FAQ

If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?

The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve.

What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?

Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)

What does "anti pump" mean in pump operation?

Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen

Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?

This method can be used to regulate flow. The advantage is that it is simple and easy to use and the disadvantage is that the throttle consumes energy

What is the lift of diaphragm pump?

Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.

What is cavitation, centrifugal pump cavitation phenomenon how to solve?

First, what is cavitation?:When the centrifugal pump shell has air, it produces less centrifugal force because the density of the air is much smaller than the density of the liquid. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is bad enough to the liquid storage tank into the pump, the centrifugal pump self suction capability, the centrifugal pump can not transport liquid, this phenomenon is called "cavitation".When a liquid drops at a certain temperature to the vapor pressure at that temperature, the liquid produces a bubble. The phenomenon of producing bubbles is called cavitation. When the cavitation bubbles, flow to the high pressure, the volume of reduced, so as to burst. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse.

The working principle of magnetic pump

Magnetic pumpBy the pump magnetic pump, magnetic actuators, motors of three parts. The key components of magnetic actuator by the external magnetic rotor sleeve, inner magnetic rotor and non magnetic components. When the motor drives the outer magnetic rotor, the magnetic field can penetrate the air gap and non-magnetic material, driven by the inner magnetic rotor is connected with the impeller for synchronization the rotation, to achieve non-contact power transmission, the dynamic seal into static seal. As the shaft, the rotor is within a magnetic pump, isolated sets of completely closed to completely solve the problem of "run, run, drip, leak, remove the oil refining chemical industry flammable, explosive, toxic and harmful media through the pump seal leakage security risks, effectively ensure the health and safety of workers.

I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?

(8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
