Functional principle of Test Pump

Its function is to convert the mechanical energy of the power machine (such as electric motor and internal combustion engine, etc.) into the pressure energy of the liquid. Working principle: The cam is rotated by the electric motor. When the cam pushes the plunger to move upward, the sealing volume formed by the plunger and the cylinder decreases, and the oil is squeezed out from the sealing volume and discharged to the required place through the one-way valve. When the cam rotates to the descending part of the curve, the spring forces the plunger downward to form a certain vacuum, and the oil in the oil tank enters the sealed volume under the action of atmospheric pressure. The cam makes the plunger rise and fall continuously, the sealing volume decreases and increases periodically, and the pump continuously absorbs and discharges oil.

Function: The pressure test pump is specially used for all kinds of pressure vessels, pipelines, boilers, steel cylinders, valves, pressure vessels, and fire-fighting equipment as an ideal equipment for obtaining high-pressure liquids in laboratories and hydraulic tests. The pressure test pump products and supporting pressure test and test projects have been applied in the pressure test test in the aviation field and in the key development projects of national defense scientific research. He has made significant contributions to major scientific research projects in my country, such as: high-pressure blasting test, deep-sea test, space technology, high-temperature and high-pressure test, special-shaped tube test, etc.
