The gas-liquid booster pump is a kind of composite piston pump, which uses a large area of low piston pressure to produce a small area of high piston hydraulic pressure. The electric pressure pump belongs to reciprocating piston pump. The motor drives the plunger to move the slide block, and then inject water into the tested object to gradually increase the pressure. This machine is composed of pump body, switch, pressure gauge, water tank, motor, etc. So, what's the difference between gas-liquid booster pump and electric pressure test pump?
气液增压泵:重量轻、体积小、携带方便;0.3 - -0.8 mpa压缩空气;无过载过热现象，达到压力，自平衡，停止工作，压降及时补压会出现电机过载，过热现象，输出压力;压力可达500MPa甚至1000MPa。低于60分贝;不产生电火花、电弧，可用于任何易燃场合，特殊场合需考虑电机的防爆等级结构和维护;结构简单，易于维护。
Gas liquid booster pump: light weight, small volume, easy to carry; 0.3-0.8 MPa compressed air; no overload and overheating phenomenon, reaching the maximum pressure, self balance, stop working, pressure drop and timely make-up pressure will cause motor overload, overheating phenomenon, and the maximum output pressure; the maximum pressure can reach 500 MPa or even 1000 MPa. Less than 60 db; no electric spark and arc, it can be used in any inflammable occasions, and the explosion-proof grade structure and maintenance of the motor shall be considered in special occasions; the structure is simple and easy to maintain.
Electric pressure test pump: heavy in weight, large in volume and inconvenient to move; 220V or 380V power supply; maximum pressure about 100MPa; noise: over 75db; complex in structure and troublesome in maintenance.
Through the above comparison, it can be clearly seen that the gas-liquid booster pump has great advantages over the electric pressure test pump. Both pumps can be used in the following situations.
Aviation industry, diesel engine, automobile, industrial machinery, tunnel engineering, oilfield industry, machine tool industry, chemical industry, pump industry, energy industry, electric power industry, fire protection, sealing, pipeline, construction, valve industry, transportation, ship industry, sewage, soil structure, scientific research (College), natural gas industry and other industries.
With the further improvement of people's understanding of the gas-liquid booster pump, the application of the gas-liquid booster pump is more and more extensive, and the electric pressure pump is gradually replaced.
