Q:Why can't the centrifugal pump pump the vacuum?
Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
Q:Advantages and disadvantages of centrifugal pumps?
The centrifugal pump has no valve, so it is suitable for conveying suspended liquid, and the special design can also transport large solid suspensionThe pump can be made of chemical resistant material, which is suitable for conveying corrosive solution.The utility model has the advantages of simple structure, few parts, little failures, durability, low maintenance cost, convenient management and reliable work.The output can be adjusted even by the discharge valve fully closed, there is no danger of infinite rising pressure head.The liquid is transferred to a large quantity. And the pressure head does not require large, most suitable for centrifugal pump.
Q:What is double hydraulic pump?
[double hydraulic pump] the same drive shaft drives the rotation of two pumps, which are connected together and driven by an electric motor. The suction port of the pump is common, and the oil pressure port is separated from each other. Pump output of two shares of flow can be used alone, can also be used in parallel. This pump, a pump can play the function of two pumps. For example, there are two pumps on the loader, a pump acting as the work, a pump acting as the steering, and the double linked pump can replace the functions of the two pumps. It works by coupling the two pumps at the same time.
Q:How many pumps does the 80cm tank use?
Mainly look at the flow of the pump, all pumps have flow signs, such as 15L/HThe above is I at random, meaning that 15 litres per hour. You should calculate the volume of your cylinder, that is, the length of the tank, the width and the height of the water surface, the unit is cm. The result is 1000, which is the volume of your fish tank
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
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:Water pump can not be pumped out, how to maintain water?
Severe vibration of water pumpIt is possible that the rotor is unbalanced, or the coupling is not good, the bearing is worn and bent, and some parts may be loosened and broken. They can be adjusted, repaired, strengthened or replaced separately.
Q:How to select hydraulic pump?
1. rpmOperating 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?
The valve opening pump is aimed at the centrifugal pump.From the power curve of the centrifugal pump, the power of the centrifugal pump increases with the increase of the flow rate; the flow curve of the centrifugal pump shows that the flow rate of the centrifugal pump decreases with the increase of the head.
Q:The main factors affecting the performance of centrifugal pumps
The low specific speed pump, on the other hand, is suitable for smaller flow and higher lift. When the pump outlet pipe diameter at the same time, if the two pumps flow similar, smaller than the speed of small head, shaft power consumption is also large. Generally speaking, the centrifugal pump with smaller revolutions than the impeller has a narrow outlet width and a large outer diameter, and the channel formed by the blade is narrow and long. If the ratio of revolutions is large, the impeller outlet is wide and the outer diameter is small, then the flow passage is short and wide.I hope my answer will be helpful to you. I hope to adopt it!
