Q:What are the characteristics of the piston pump?: 1 、 built in overvoltage protection and flow correction system.6 、 large screen LCD display.7. The well designed exhaust device can effectively remove the bubbles in the liquid.8, flow and pressure settings can be memory, and PLC communication (custom).

Q:Why can't the inlet of centrifugal pump be negative pressure?: However, the centrifugal pump will have its import pressure requirements, which is to prevent cavitation, that is, the fear of the delivery of liquid at low pressure will occur gasification. Centrifugal pump has an important parameter called NPSH, for example relating to the inlet pressure, the pump NPSH, 4 meters, it means that the absolute pressure of imports should be higher than the saturated steam conveying fluid pressure of liquid column is 4 meters high, so, when it is at a temperature of saturated vapor pressure for water transport 2 meters, 4+2=6 meters minimum inlet absolute pressure. Because the absolute pressure is 10 meters water column atmospheric pressure, at this time the entrance negative pressure is 10-6 meters =4 meters water column.

Q:How many concrete pump tube diameter: The pump is generally divided into 125 and 150 two, the inner diameter is 125mm and 150mm. And the two kinds of each have high and low pressure points. Low pressure type type 125 pump for the pipeline diameter is phi 133,

Q:What are the causes of pump shock?: Troubleshooting cause1. bearing damage, replace new bearings2., coupling pin, bolt damage, rubber column or metal bolt wear, change

Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.: One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.

Q:Harm of air pump and pump: Centrifugal pump situationEmpty pump is divided into two kinds, if there is no liquid, then it will cause the mechanical seal of the pump to overheat, wear and even die

Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?: Mechanical efficiency: the ratio of theoretical torque to actual torque of the pump.

Q:What is the function of the heating pump system for the water pump design?: As the feed water temperature is higher, in the case of non warm pump start, will make the pump body is subject to greater thermal impact; in addition, the flow components with the pump contact heating fast, not contact with water directly heating slowly. This expansion due to uneven speed, it will inevitably produce thermal stress, deformation of the pump body, sealing surface, the joint surface is lax and leaking phenomenon. Therefore, the warm water pump system is designed for the water pump.

Q:What is the cause of the damage of pump bearings?: Is the water pump motor overheating or damaged leaves overheating, resulting in overheating bearings, lubricating oil dry, excessive wear and tear guide system damage

Q:Water pump outlet valve sequence: Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.
