According to the structure principle of the shotcrete machine, it can be divided into four types: cylinder type, screw type, rotor type, and hydraulic type.
According to the number of nozzles, it can be divided into single shotcrete machine, double shotcrete machine, and three shotcrete shotcrete shotcrete machines.
According to the degree of automation, it is divided into ordinary concrete shotcrete machine and concrete wet spraying manipulator (intelligent wet spraying trolley)

What is wet sandblasting?

Wet blasting is a technique for surface preparation using water, abrasives and compressed air.

"Wet blasting" refers to a technology that uses the power of compressed air to spray a mixture of water and abrasives at high speed to achieve surface cleaning, processing and modification of metals, plastics, ceramics and other materials. Since it is wet processing, it is also suitable for fine processing using abrasives as small as several microns.

Advantages of wet blasting

Wide selection of abrasive grain sizes, shapes and materials
Because the abrasive particles are carried by water to the target, finer particles can be used compared to dry blasting.

High fluid control and controllability
The grinding fluid mixed with water and abrasive grains can realize fluid control, so the processing precision is higher.

Less abrasive residue
After machining, the abrasive particles are washed away by water, so less particles remain on the machined surface.

Capable of handling ultra-thin targets
The processing pressure is small, and the ultra-thin target will not be damaged during processing.

Adding chemicals can get the effect of secondary treatment
Chemicals can be dissolved in water, and chemical treatment can be performed at the same time as sandblasting.

The principle of wet sandblasting

Wet sandblasting is an easy-to-automate and environmentally friendly way to circulate the grinding fluid.
The basic principle of wet sandblasting is as follows. The grinding liquid (mixture of water and abrasive) in the grinding liquid tank is drawn to the sandblasting gun by a pump, and is sprayed onto the target material by the action of compressed air in the sandblasting gun. The grinding fluid is recovered to the grinding fluid tank for recycling. Click here to know more wet blasting machine details.

Wire saws are mainly divided into electric wire saws and hydraulic wire saws according to power

Advantages and disadvantages of electric wire saw

1. The saw head is relatively heavy. In actual construction, you can fix the saw head by directly pressing the bottom corner without using expansion screws, which greatly reduces the damage to the concrete cutting.

2. There is no need for a lot of cooling water. Anyone who has used hydraulic wire saws knows that hydraulic pumping stations must use cooling water to cool the oil temperature to reduce the problem. Electric wire saw machines do not need a lot of cooling water, only the rope head Just add cooling water, it can work for a long time.

3. Low cost: It can be operated by household electricity, eliminating the need for hydraulic system, so the cost is much lower.

Disadvantages: Inferior to hydraulic wire saws, it is flexible in construction, especially in places where the construction area is narrow. 2. The power is not as strong as the hydraulic power, and the efficiency is slower than that of the YG hydraulic wire saw.

Overview of hydraulic wire saw

The hydraulic wire saw is a new generation of fully automatic reinforced concrete cutting equipment developed by our company based on years of construction and product design experience. The machine has strong power, adopts Australian motors and Italian hydraulic components, guarantees the lightest design under the same volume, and ensures that the cut is straight and tidy during construction, without trimming. And it can be cut on reinforced concrete, ceramics, and glass. No vibration when working, low noise and accurate positioning, very suitable for cutting complex sections.

The hydraulic wire saw is widely used in cutting and dismantling industries such as reinforcement and reconstruction of houses, bridges, floors, beams and columns. The hydraulic wire saw can meet the cutting depth that the wall saw cannot reach, and the cutting depth is not limited. YG hydraulic wire saw machine is mainly composed of a hydraulic wire saw unit and a hydraulic power station group, and cooperates with a directional wheel or a universal wheel and a rope for cutting operations.

The portable vertical all aluminum single operator hydraulic wire saw machine produced by our factory can cut various kinds of thick concrete. It is the most suitable cutting construction equipment for cutting, dismantling and repairing concrete walls, bridges and pillars. The wire saw can be used for closely arranged reinforced concrete structures and even for underwater cutting from 30 meters to 50 meters. The hydraulic rope saw can meet the cutting depth that the wall saw can not meet, and the cutting depth is not limited. At present, it is the leading advanced cutting construction equipment widely used in the construction of buildings, bridges, tunnels and wharf reconstruction, which replaces the traditional methods of hard-hitting, drilling and blasting.

Working principle of drilling pump

If the entire drilling construction process is compared to human life activities, then the drilling pump, like the human heart, is the source of continuous circulation of drilling fluid from the ground to the bottom of the well, and then back to the ground from the bottom of the well. The drilling pump sucks the drilling fluid in the circulating tank, and at a pressure of 10-30 MPa and a delivery displacement of 20-60 liters per second, it passes through the ground high-pressure manifold, hose, drill pipe, and drill nozzle to the bottom of the well. , It will also form a high-pressure jet when flowing through the nozzle of the drill bit. Play the role of breaking rocks, cleaning the bottom of the well, and cooling the drill bit. When drilling with bottom hole screws or turbodrills, drilling fluid is the power source for power drilling tools. If the drilling pump fails to work normally and the drilling fluid cannot maintain circulation during the drilling process, downhole drilling engineering accidents will occur. It's as if the human heart stopped beating. Click here to know more details.

Drilling pump classification

A reciprocating pump is a kind of drilling pump commonly used in oil drilling rigs, and its function principle is exactly the same as that of general reciprocating pumps. The power end of the drilling pump is a set of crank and slider mechanisms. Because the liquid transported is mostly mud, it is also called a mud pump. There are many types of drilling pumps, which can be divided into double-cylinder pumps and triple-cylinder pumps according to the number of hydraulic cylinders of the pump. According to the number of times the piston sucks or discharges liquid once, it can be divided into single-acting pumps and double-acting pumps. At present, the most widely used oil drilling rigs at home and abroad are double-cylinder double-acting and triple-cylinder single-acting piston drilling pumps.

Work efficiency

The efficiency of the drilling pump directly affects the speed and progress of drilling. The pump valve, piston, cylinder liner and seal of the YG mud pump are the weakest parts of the drilling pump because they have been working in the drilling fluid containing fine sand for a long time, and the working environment and conditions are harsh. In recent years, with the joint efforts of scientific research and manufacturing units, my country has developed a number of high-quality, long-life drilling pump accessories, which greatly improves the working efficiency of drilling pumps.

Mud pump development

In the 1980s, due to the rise and development of jet drilling technology, the matching update speed of high-horsepower drilling pumps was greatly accelerated. In just over ten years, the mud pump has developed from 600 horsepower in the past to 800, 1000 and 1300 horsepower now. Individual deep well drilling teams are also equipped with 1,600-horsepower drilling pumps.

Why is the epidemic coming back?

The mismatch of the new crown vaccine + the mutation of the virus + the slack prevention and control of the epidemic has led to the fourth wave of upward trend in the overseas new crown epidemic.

With the continuous vaccination of vaccines, the epidemic should gradually recede. But in fact since March 2021, the global new crown epidemic has shown signs of continuous rebound, and the number of new confirmed cases in a single day has once again soared.

In the past five days (April 20-April 24), the number of newly confirmed cases abroad in a single day reached 759 thousand, 787 thousand, 849,000, 1.070 thousand, and 865,000 respectively, compared with February 2021 The daily level of 300,000 to 400,000 new cases has almost doubled, and it has refreshed the previous historical high in December 2020. The WHO also stated at a recent press conference that the current situation is close to the highest infection rate since the outbreak.

The overseas new crown epidemic is experiencing a fourth wave of upward movement (the first wave is in March 2020, the second wave is in July 2020, and the third wave is in December 2020).

How to control the epidemic in India

As the epidemic situation eased at the beginning of the year, epidemic prevention and control measures in various countries have been loosened, especially in populous countries such as Brazil and India. The people's failure to observe the prevention and control measures such as wearing masks and maintaining social distancing, and holding large-scale gatherings caused the epidemic to break out on a large scale again. If you work in airports, railway stations, large supermarkets, hospitals and other places, the intelligent ultraviolet disinfection robot and disinfection door will be your right-hand man in disinfection.

India is the country with the worst epidemic in this round, and it is facing a situation of out of control. In the past 24 hours, there were nearly 400,000 new cases in a single day. There have been more than 300,000 new confirmed cases in a single day for several consecutive days, and it continues to set new highs. The cumulative number of confirmed cases has exceeded 17 million.

Another large-scale outbreak of the epidemic in India is closely related to the previous government’s approval of the opening of the Big Pot Festival. The Big Pot Festival is a very large religious gathering, which also includes bathing in the Ganges River. Almost a million people enter the Ganges every day Participate in religious ceremonies.

In addition, the vaccine progress is slow (the two-dose vaccination rate is less than 2%, and the one-dose vaccination rate is less than 10%. The United States has “stuck the neck” on key raw materials, causing major problems in the local vaccine supply), and the spread of mutant strains (locally) B.1.617 double mutated virus, in recent sampling, India B.1.617 virus has accounted for 70.4%) also objectively aggravated the outbreak of the epidemic in India.

The epidemic situation in India has become out of control. Due to the large number of patients and the shortage of medical resources, many local designated hospitals have even shared the same multifunctional hospital bed for two patients, and there has even been a nationwide oxygen shortage.

Medical oxygen generator exports

At the present, many countries including China rushed to aid India in an emergency. Hundreds of oxygen generators were delivered to it, including large-scale PSA medical oxygen generators. Small medical oxygen generator. Personal household oxygen generators, etc. As a leading manufacturer of oxygen concentrator in China, YG Engineering company is also increasing its production speed, and doing its best to let the Indian people use high-quality and efficient YG oxygen concentrators to resist the disease.

Introduction of drilling rig machine

Drilling rigs are mechanical equipment for drilling holes on the surface. Drilling rigs include outdoor drilling equipment for large water wells, oil wells and natural gas wells. It also includes small devices that can be moved by a single person, called augers.

Drilling rigs can sample underground mineral deposits or be used to install underground production equipment. Such as underground machinery, instruments, pipelines and hoistways. Drilling rigs can be mobile equipment installed on trucks, trailers, or tracks.

Drilling rigs can also be relatively fixedly installed on land and offshore structures (such as drilling platforms, which are generally referred to as "offshore oil rigs", although they do not include drilling rigs). The term "drilling rig" generally refers to equipment that drills into the earth's crust.

The rig includes

Small portable drilling rig. Such as mining drilling, water wells drilling machine price, environmental survey drilling rigs.

Large-scale drilling rigs can drill the earth's crust to a depth of more than thousands of meters. During the drilling process, the mud pump circulates the mud through the drill pipe and the drill bit into the casing annulus to cool the drill bit and remove cuttings.

The lifting system on the drilling rig can lift hundreds of tons of drill rods. Other equipment can pump acid or sand into the reservoir, perform fracturing operations, and guide crude oil or natural gas out of the reservoir to the surface. In remote areas, drilling rigs can be equipped with permanent residential facilities, eating tools, etc., which can be provided for the daily lives of more than one hundred employees. Offshore drilling rigs can operate at a distance of several hundred kilometers offshore, and personnel on the well will rotate.

Drilling rigs are classified according to drilling type

Because different YG drilling rig types allow drill rods to enter the borehole in different ways, each has advantages and disadvantages. According to the depth that can be drilled, sampling type, cost, and insertion rate, there are two basic drilling types. : Cuttings drilling and core drilling.

DTH drilling machine for sale

Down the hole drilling uses a spiral drill to rotate into the ground, and the soil is lifted to the ground through the gap of the spiral blade. Hollow drill pipes can be used for drilling, geological drilling, soil engineering and geochemical exploration of mineral deposits in soft soils such as swamps and other soils where the soil does not open naturally. Solid flying drills/short tube augers are used for hard soil drilling. Sometimes, mining shafts are drilled with auger rods. Small drill machine rods can be installed on trucks, and large augers can be used to place bridge foundations.

Spiral drill pipes are generally used for relatively soft unconsolidated materials or rocks in bad weather and are characterized by economy and speed.

Disposable latex glove production line Production process

To produce disposable latex gloves, the main raw materials and additives are first stirred and mixed in a special container in a certain proportion to form an emulsion. After filtering, vacuuming, and standing still, the mixture is pumped into the dipping tank in the production line. Under normal production conditions, the hand molds on the assembly line automatically enter the dipping tank, and the hand molds that adhere to the emulsion come out of the dipping tank in turn, and continuously rotate during the journey to make the emulsion on the surface of the hand mold uniform and make the excess emulsion hang down. Drip down. The dripping liquid returns to the immersion tank through the collection tank.

After dripping the excess emulsion, the hand mold moves into the oven with the production line. The temperature of the oven is controlled at 230-250 degrees Celsius. Under this condition, the emulsion that is touched by hand is cured and formed. The hand mold coming out of the oven undergoes processes such as natural cooling, lip curling, and powder dipping. The gloves are manually removed from the hand mold, and the hand mold continuously moves to the dipping tank. The unloaded disposable latex gloves will be put into storage as a finished product after powder removal. Check here to know more details.

How are latex gloves produced through the latex production line?
1. The production process of latex gloves through the latex production line is as follows:

 (1) The rubber is first sliced by a rubber mixing machine, and then sent to the sol tank to mix with gasoline for sol. After the sol is emulsified and prepared, it is pumped to the latex intermediate tank.

 (2) (The rubber solution dissolved in gasoline is fed from the top of the distillation tower, heated by steam for distillation, the light component gasoline is heated into a gas phase, and the gasoline gas is mixed and cooled by cold water in the oil-air cooler. The oil-water mixture is then sent to the oil-water separator, Oil, and water layer. The upper gasoline is recovered, and the lower water is pumped to the cooling water tower for cooling, and then the gas gasoline in the distillation tower is cooled after cooling;

 (3) The latex of the distillation tower kettle is sent to the latex mixing tank for stirring according to its own pressure, and after preparation, the glove material latex is separated out by the centrifuge, and then it is toned and filtered for later use.

 (4) The glove model is first cleaned with acid and alkali and washed with water. The washed model is first immersed in hot water and heated until it is soaked with coagulant and dried for dipping. After dipping, it is sent to the oven for preliminary drying, adding fiber inner sleeve, flushing hot water,  and then sending to the oven for vulcanization, drying, and forming. After the gloves are demolded, they are inflated, checked, shaped at low temperature, dried at medium temperature, washed with water, dehydrated, dried, and then packaged and sent to the finished product warehouse.

2. Latex gloves produced by the latex production line: it is a kind of gloves. It is different from ordinary gloves and is made of natural latex. It can be used in household, industrial, medical, beauty, and other industries, and it is necessary for hand protection. Supplies.
