Pressure test pump The pressure test pump is mainly used for the detection of various pressure vessels, valves, pipelines and other pressure-bearing parts, and is also an important tool for blasting tests such as gas cylinders and high-pressure hoses. When choosing a pressure test pump, it is necessary to choose according to the actual pressure detection requirements, and cannot only take the pressure or flow rate as the standard. If possible, try to improve the efficiency during the pressure test, such as filling the test container or equipment in advance to avoid air or water during the test process, so as to better ensure the quality and accuracy of the test. The working principle of the pressure test pump is like a sophisticated instrument. The cam rotates under the drive of the motor, which pushes the plunger to move upward, so that the sealing volume composed of the plunger and the cylinder body is reduced, and the oil is squeezed out of the sealing volume and discharged to the required place through the check valve. When the cam rotates to the descending part of the curve, the spring presses the plunger downwards to form a certain vacuum, and the oil in the tank enters the sealing volume under the action of atmospheric pressure. This periodic lifting movement causes the plunger to continuously suction and drain oil, thus maintaining the continuous operation of the pressure test pump.
When it comes to maintenance and upkeep, the pressure test pump also needs to be properly cared for. Before starting to use, check whether the connections and pressure gauges of each component are normal, keep the working medium clean, and avoid using water containing sediment or other contaminants. In the process of pressure test, if there is air or water mixture, the work should be stopped immediately for inspection and repair. After the pressure test is completed, the water valve should also be loosened to let the pressure drop to protect the pressure gauge and avoid damage.
In general, the pressure test pump is an efficient and accurate testing equipment, which provides strong support for the quality inspection of various pressure devices. In the process of use, it is necessary to strictly follow the operating procedures to ensure its normal operation and prolong its service life.
