FAQ

What's the submersible pump?What is a submersible pump, and what about it?

Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.

What is a water pump coupling device?

The automatic coupling device of the water pump coupling device has compact structure and small occupation area. The sump pump works because it is submergedThe utility model can be directly installed in a sewage pool, and no special pump house is needed to install a pump and a machine, thereby saving large amounts of land and infrastructure expenses

Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines? Why?

Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value

Why is the flow of the pump too small will occur cavitation phenomenon?

Why is it easy to produce cavitation when the inlet flow of pump is lowered?This is because the main performance parameters such as the head, power and efficiency of the centrifugal pump are not fixed, but vary with the flow rate. The curve drawn on a coordinate paper is called the performance curve or characteristic curve of the centrifugal pump. What happens when the flow rate decreases? The disadvantage of throttling adjustment is that the pump flow is small, and the impeller is easy to cause cavitation

What are the characteristics of a pipe shield pump?

According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.

What are the main performance parameters of hydraulic pumps?

Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.

Why can the centrifugal pump hold down the pressure?

The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).

What are the starting and stopping procedures for centrifugal pumps?

Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.
