Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?

As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump

Q:Rules for operation of centrifugal pumps

3, start the pump, wait until the speed reaches the normal speed, slowly open the outlet valve, observe the ammeter at the same time, and control the current in the rated current range of the motor.4, the operation requires smooth operation of water pumps, no abnormal noise, no pressure fluctuations. The abnormal situation should be stopped in time.

Q:You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?

Q:What are the failures and causes of the replacement of the fuel pump assembly?

Common troubles of gasoline pump:Gasoline pump supply shortage of gasoline pump supply depends on the pump membrane stroke, stroke, pump oil should be more; however, the amount of gasoline pump oil pump will reduce the consumption of gasoline engine, and the fuel pump is inevitable, if the engine fuel consumption, but the actual amount of oil is less, this situation is the amount of oil in the petrol pump, there will be a float chamber of a carburetor oil level is reduced, the engine power shortage.

Q:What is the name of the day pump and ground pump? Specific introduction

PumpGround pumps are used very frequently in many large basements, because they have no boom, so they need to be taken over manually. In addition to the site, for those days to pump the high-rise buildings, such as 200 meters or 200 meters altitude, can also take over to transport concrete by pump, but the premise is to have enough power to pump concrete will hit above the height and the length of nozzle can reach the height of the floor.Thus, the day pump and ground pump have their respective advantages. The pump is easy to use, but the ground pump can make up for the height that the pump can not reach. At the same time, the price is relatively cheap, so users can choose the corresponding concrete pump when they are in use.

Q:How to adjust the flow of piston pump?

Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.

Q:What does "dual purpose" of water pump mean? Please expert advice

2, the pump must pay attention to maintenance after use, for example, when the pump is used up, the water pump should be put clean, it is best to remove the water pipe, and then rinse with water.5, the water pump on the tape should be removed, and then rinse with water after drying in the light place, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.6, to carefully check whether there are cracks in the impeller, the impeller fixed to the bearing on whether there is loose, cracks and loose if the phenomenon to be timely maintenance, if the water pump impeller should also be above the earth clean.
