Q: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.
Q:How does the centrifugal pump pump and cut the pump?
Check the motor, pump and fasteners in good condition; whether the lubricant is added or not;Disc dynamic coupling, whether or not stuck phenomenon;Open the inlet valve, remove the gas in the pump or pump the gas out of the pump;
Q:Hydraulic pump displacement refers to the pump shaft what?
You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
Q:Must the water pump in the tank be all soaked in water?
Of course, if the motor is overheated, it will burn, and the temperature of the water will drop down.
Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)
Q:Troubleshooting of diaphragm pump
In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
Q:Water pump dead center lift
The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa
Q:What is the function of the heating pump system for the water pump design?
Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.
Q:What is the difference between centrifugal pump and self suction pump? Which is better?
If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Working pressure - the actual working pressure of the motor, that is, the pressure of the input oil. The difference between the motor inlet pressure and the outlet pressure should be calculated.Rated (nominal) pressure under normal working conditions, according to the test standards for continuous operation of the maximum pressure, that is, the rated pressure, more than the maximum pressure is called overloading.
