Q:The working principle of magnetic pump
Working principle of magnetic pumpN of the magnet (n is even) arranged according to the laws in the magnetic clutch assembly inside and outside the magnetic rotor, the magnet part consisting of magnetic coupling system. When the inside and outside the two poles in different relative displacements, two poles between the angle phi = 0, the lowest energy magnetic system; when rotates to the relative displacement is two poles, pole angle between phi = 2 pi /n, the magnetic system of magnetic energy. Remove the external force, due to the magnetic system of magnetic poles repel each other, magnetic magnet will return to the lowest energy state. So magnets in motion, driven by the magnetic rotor.
Q:What are the reasons for sealing damage of centrifugal pumps?
Two, cavitation. Cavitation (mainly from a thermal centrifugal pump).Because the medium is hot water, the water temperature is too high to produce steam, the gas in the pipeline enters the pump cavity height, and the part of the gas can not be discharged, thus causing water shortage to run, the machine seal dry grinding is invalid, and the cavitation erosion device is not available.Process: replace the machine seal.
Q:What is the pumping property of concrete?
Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
Q:60 type concrete pump performance?
HBT60.13.90S performance parametersParameter name unit HBT60.13.90SMaximum theoretical concrete conveying capacity m3/h 69/43Maximum pump outlet pressure Mpa 13/7
Q:What does centrifugal pump mean horizontally?
Centrifugal pump: centrifugal pump is a centrifugal force on the impeller rotates to transport liquid pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
Q:Working principle and diagram of axial piston pump with pressure compensation variable
Adjust the flow characteristics, the first limit screw to the top, according to the flow and pressure changes in the required range, adjusting the spring set, the initial flow pressure began to change to meet the requirements, then the limit screw to the ultimate pressure when the flow is no longer changed, the relationship between flow and pressure the changes are determined by the pump itself.
Q:Constant pressure pump working principle
15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
Q:5 floor water pressure is too low, what kind of water pump is better?
Installed pump flow, lift did not meet the requirements, this will need to re type selection, calculation;
Q:What is the Rhodes pump?
Best answerRoots vacuum pump (referred to as: Roots pump) refers to the pump is equipped with two opposite direction of synchronous rotation of the leaf rotor, rotor, rotor and pump housing between the walls of a small gap and no contact with a variable capacity vacuum pump.Roots vacuum pumps have been tested for long time in the fields of petroleum, chemical, plastic, pesticide, steam turbine rotor dynamic balance and aerospace simulation, so it should be popularized and applied in china. It is also widely used in petroleum, chemical, metallurgical, textile and other industries. Vacuum pump fittings are used for noise control of vacuum pumps, vacuum pump silencers.
Q:How to calculate the motor power of metering pump?
The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
