Q:What is a positive displacement pump? He Weizheng displacement?
Includes a pump housing (10), a pump chamber (24), the pump chamber has an entrance channel (21) and an outlet check valve (17) export control channel (28), a displacement member (13), the definition of the pump cavity in a direction of movement in (24) and in a stroke section in the pump cavity (S) in reciprocating motion
Q:Metering pumps related matters
1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
Q:What's the difference between non negative pressure and variable frequency water pump?
No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure
Q:Household automatic booster pump, how much pressure can you work automatically?
Household automatic booster pump is not started by pressure, it is induced water pump, that is boiled water faucet
Q:Water pump does not produce water, what are the reasons?
The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.
Q:Water pump dead center lift
Should shut down the valve bar, reduce the flow to increase the point of the head, it is best to adjust within the best range of work, otherwise it is easy to cause the current is too large, burning the motor
Q:What is the name of the day pump and ground pump? Specific introduction
Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.
Q:Why can't the centrifugal pump pump the vacuum?
Condition:The pump shell must be filled with liquid under certain installation height and running without leakage.What is the phenomenon of centrifugal pump? What harm does it have? How to eliminate?)
Q:What is the difference between centrifugal pump and positive displacement pump?
The centrifugal pump is to rely on high-speed rotation of the impeller to do work on the fluid. These two types of pumps are also the most widely used.
Q:What is the difference between the ground pump and the pump in the commercial concrete?
Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly
