[Asia pump network] The concrete machinery market has also been rapid development, including pump in the booming construction market plays an important role in the domestic hydraulic reciprocating piston pump has experienced from scratch, from weak to strong development process . With the market warming, pump manufacturers continue to emerge, different manufacturers, models of pump products more and more. Let us talk about the working principle of the pump. The working principle of the pump Working principle of the pump can be described as: When pumping concrete material, under the action of the main cylinder, the concrete piston 7 moves forward and the concrete piston 8 retreats, meanwhile, the distributing valve 10 communicates with the concrete cylinder 5 under the action of a swinging cylinder , Concrete tank 6 and hopper connectivity. So that the concrete piston 8 retreat, the hopper concrete will be sucked into the concrete tank, concrete piston 7 forward, the concrete tank concrete material sent to the dispensing valve. When the concrete piston 8 retreats to the end of the stroke, the reversing device 4 in the water tank 3 is triggered, the main cylinders 1 and 2 are switched over, the swing cylinders 12 and 13 are switched over, the distribution valve 10 and the concrete cylinder 6 are communicated, and the concrete cylinder 5 Connected with the hopper, then piston 7 back, 8 forward. The next cycle, in order to achieve continuous pumping. In the anti-pump, the concrete cylinder in the suction stroke is communicated with the distribution valve through the anti-pump operation, and the concrete cylinder in the push stroke is communicated with the hopper, so that the concrete in the pipeline is withdrawn to the hopper. Concrete pump is the main equipment of cement concrete machinery, used for vertical and horizontal concrete delivery work. With high efficiency, good quality, high degree of mechanization and operation from the site conditions and can reduce environmental pollution and so on. Germany pioneered the pumping of concrete construction technology in 1927 and was the fastest growing country in the world for pumping concrete in Europe. By 1973, the penetration rate of pumping concrete reached 40% to 50%. The United States and Japan have also developed rapidly following the introduction of German technology and have also become the countries with the highest pump concrete penetration rates. In the early 1980s in our country, pumping concrete began to be widely used, its application range throughout water conservancy, hydropower, tunnels, subways, bridges, large-scale foundations and high-rise buildings and Other projects. Hope that the low starting point of our country's transmission pump will not affect the development of this industry in our country, at the same time, it is hoped that the transmission pump can provide help for the economic development of our country.
