Q:Is the centrifugal pump large or small?
NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.
Q:Centrifugal pump flow, why can be adjusted through the outlet valve?
Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.
Q:The water tank of the fish tank does not air out and only has the water outlet
The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.
Q:Hydraulic pump displacement refers to the pump shaft what?
Just as you carry a spoon to the water. How much water can you pump at once (every turn)? That's the displacement.
Q:Why adjust the centrifugal pump outlet valve can adjust the flow?
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
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
Q:What is the difference between an air pump and a water pump?
Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
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.
Q:What are the main performance parameters of hydraulic pumps?
speedOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.
Q:Why do we need to stop the pump?
And the pump at the start, if the valve opening pump, then the pump outlet pressure (head) is very small, so the pump flow will be great, the pump power is very large, causing the start-up current is very large. In addition, the starting current of the motor itself is also very large. These two factors add up to the possibility of overloading the motor, resulting in failure to start or even burn the motor.
