High-pressure pump for high-pressure rotary jet grouting to provide high-pressure power for new buildings, highways, high-speed rail, underground railways and other soft ground strengthening reinforcement, uneven settlement of old buildings, reservoir dam and under the building High-pressure pump can also be used in high-pressure water intake to avail rock breaking coal, underground hydraulic prop for liquid supply, anchoring water conservancy expansion Metal anchor pumps high-pressure water, large underground dredging cleaning dredging, high-pressure water jet perforation or other areas need to use high-pressure liquid as the driving force. There is another kind of high-pressure pump to do burst pressure test booster pump. Widely used in various industries. Blasting experiments. G series of gas-liquid booster pump with a single gas-controlled unbalanced gas distribution valve to achieve automatic reciprocating pump, gas drive part of the pump body made of aluminum. Wetted part of the media according to different choice of carbon steel or stainless steel, pump full set of seals are imported high-quality products, thus ensuring the pump performance. There is also a new type of high-pressure pump, with high pressure, high flow, compact structure, low noise, long life, fast response, impact resistance and so on; is only made in recent years, the localization of constant pressure variable displacement radial piston pump , Radial piston pump, widely used in ships, steel, machine tools, mining, tin magnesium and other products industry, is a lot of plunger pumps and other types of pump ideal replacement products! High pressure pump with a circular plunger and hydraulic cylinder as the main components. When the plunger of the high-pressure pump is reciprocated in the plunger hole, the volume of the closed oil chamber formed by the plunger and the plunger hole is changed, so as to realize the oil suction and pressure oil work. Changing the working stroke of the high-pressure pump plunger can change the displacement of the pump. High pressure pump with high pressure, high volumetric efficiency, easy flow adjustment and so on. The disadvantage of high-pressure pump is the structure is more complex and costly. High-pressure pump can be divided into radial high-pressure pump and axial high-pressure pump two categories.
