Plunger Metering Pump

Through its unique working principle, the petrochemical plunger pump in power plant plays a key role in the occasions of high pressure, large flow and the need for flexible adjustment of flow. Its working principle mainly includes the following aspects: First, through the reciprocating movement of the plunger in the cylinder block, to achieve the function of suction and discharge of liquid; Secondly, the use of check valve to control the flow of liquid, to ensure the normal operation of the pump; Finally, by changing the motion state of the plunger, the flow of the pump can be flexibly adjusted. Because the plunger pump has a high working pressure. Its plunger and plunger hole processing is simple, dimensional accuracy and surface quality can reach very high standards, tight fit, less oil leakage, making the volumetric efficiency significantly improved. Its working pressure range is usually 20~40MPa, and even up to 100MPa. And the flow rate is easy to adjust. This flexibility and adaptability make the plunger pump in power plant, petrochemical, hydraulic press, construction machinery, ships and other fields have a wide range of applications. But its shortcomings are also obvious, first of all, the cleanliness of the working medium is required to be high, if the medium contains impurities, may affect its performance. Secondly, its flow pulsation is relatively large, and the noise generated is also relatively high. Therefore, we must be careful in the selection.

The carton should be the right size, the quality is not damaged, deformed, and can bear the weight of the loaded goods. Stuffing such as foam board, bubble wrap, old newspaper, shredded paper, etc. can be used to protect the contents of the box
