There are many models of QST series, such as: QST70, QST70-J, QST140, QST140-J, QST140B, QST140B-J, QST140C, QST140C-J, etc. The following table is the QST series of imported pneumatic pressure test Pump parameters introduced in detail: Imported pneumatic pressure test pump is the use of compressed air as the power source to the pneumatic pump pressure source, the output hydraulic pressure and gas pressure proportional to. By adjusting the pressure of the air supply, the corresponding hydraulic pressure can be obtained. When the gas pressure and hydraulic pressure balance, the pneumatic pump will stop filling pressure, the output hydraulic pressure will also be stable at the preset pressure, by controlling the size of the intake air to control the boost speed. Therefore, explosion-proof, adjustable output pressure, step-up speed controllable, small size, light weight, simple operation, reliable performance, wide range of applications. It is especially suitable for high-pressure and extra-high pressure test of anti-blowout equipment, valves, pipes, connectors, pressure vessels and other pressurized equipment in oilfield drilling engineering. Also suitable for scientific research, testing departments for testing tools. QST series of imported pneumatic pressure pump has so many different types of parameters, we should understand it, so as to better and correct choice of products in line with their own. Hope that the detailed parameters of the above products can give you help! Further reading: Canton IFAT China Water Show article belongs to the construction industry interconnect (Xiamen) Co., Ltd.
