Why does the high-pressure pump not discharge water

High pressure pumps are suitable for high-pressure water descaling in crude oil, chemical plants, and organic fertilizer industries, as well as high-pressure water cleaning, scale cleaning, oil and gas field filling, heating furnace water supply and drainage, hydraulic equipment, and power devices in food and pharmaceutical industries that must cause a portion of high-pressure liquid in industrial production such as engineering, shipbuilding, sugar making, paper making, and chemical plants, The conveying medium is a liquid without solid particles. As a capacity type high-pressure reciprocating pump, in the process of model selection, it is necessary to clarify the total flow pump head of the high-pressure pump, the main purpose, and select a suitable high-pressure pump; The materials used for high-pressure pumps should be corrosion-resistant. If the medium causes corrosion to the pump during transportation, it not only causes damage to the high-pressure pump, but also has a high possibility of causing damage to the body. In addition, the sealing characteristics of high-pressure pumps are reliable, especially in controlling the leakage amount of flammable, explosive, harmful, and precious media, and even completely no leakage. The medium being transported is liquid vapor, and it is necessary to control the pump speed and temperature of the high-pressure pump. During the specific application process, it was suddenly discovered that the high-pressure pump did not produce water, which resulted in many reasons for this situation, such as gas in the water inlet and pump body; The speed ratio of the high-pressure pump is too low; The bottom valve cannot be opened; The bottom valve filtration device screen is blocked; The centrifugal impeller is severely damaged; Common faults or blockages in the reversible check valve of the shut-off valve can lead to a decrease in total flow rate or even inability to pump water; Leakage of the inlet and outlet pipelines can also endanger the water flow rate. Therefore, it is necessary to clarify the causes of common faults and handle them purposefully.
