Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?
Centrifugal pump cavitation phenomenon how to solve?:Measures to improve cavitation resistance of centrifugal pumps(1) improve the design of the suction port of the centrifugal pump to the impeller. Increase flow area; the radius of curvature increases the impeller cover inlet section, reduce the flow accelerated sharply with pressure; reduce the thickness of the blade, and the blade inlet rounded, close to the streamline, can also reduce the acceleration and pressure flow around the blade head portion of the impeller and the blade inlet part; improve surface finish in order to reduce the resistance loss; the blade inlet edge extends to the impeller inlet, the liquid flow in advance to accept work pressure, improve.
Q:How to install, operate and maintain the pipeline booster pump?
When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, 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.
Q:How many concrete pump tube diameter
The pump tubing diameter is 125MM general concrete or mortar pump tube diameter is 80MM fine stone
Q:Is the diaphragm pump and the drain pump one?
Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.
Q:What is the cause of the damage of pump bearings?
In high-speed equipment, the most likely damage to bearings is high temperature.
Q:Why is the submersible pump tripped on an electrical switch?
There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped
Q:What are the ways of hydraulic pumps?
Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Normal words are needed, but when you check and check, has anyone checked?
Q:What is a feed pump?
Feeding the role of the pump is to make the injection pump inlet pressure, increase the injection pump inlet pipe flow rate, in order to ensure high pressure water injection pump has sufficient supply.
Q:Rules for operation of centrifugal pumps
Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.
