Q:Working principle and structure of external gear pump

When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, and the pressure is lowered, and the liquid in the suction pipe is sucked into the pump; the suction liquid is divided into two parts to be pushed into the discharge chamber by the gear in the alveolus. When the liquid enters the exhaust chamber, the liquid is squeezed and discharged from the exhaust chamber into the discharge pipe because the teeth of the two gears are continuously engaged. The driving gear and the driven gear keep rotating, and the pump can continuously inhale and discharge the liquid. The pump body is equipped with a safety valve, when the discharge pressure exceeds the required pressure, the delivery liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe.

Q:What is a solution pump?

(4) smooth running, low noise, no lubrication, no lubrication and low noise due to the absence of rolling bearings and motor fans(5) a wide range of use, the high temperature, high pressure, low temperature, high melting point and other conditions are able to meet the requirements2.2 shielding pump shortcomings(1) because the shielding pump adopts sliding bearings and is lubricated by the medium to be transported, the medium with poor lubricity should not be transported by shielding pump. Generally, the viscosity of the pump medium is 0.20mPa.s.(2) the efficiency of shielding pump is usually lower than that of single end mechanical seal centrifugal pump, which is approximately equal to that of double end mechanical seal centrifugal pump(3) long time in small flow operation, shielding pump efficiency is low, will lead to heat, make the liquid evaporation, and cause the pump to dry, and thus damage the sliding bearingsCanned pumps can be divided into the following types: 1) basic type 2) reverse circulation type 3) high temperature type 4) high melting point type 5) high pressure type6) self priming 7) multi stage 8) mud type

Q:What is the distance between the pump and the wall?

What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.

Q:Significance of water pump model ISO50-160

Meaning of water pump model ISO50-160: ISO- stands for international standard code (IS). 50- indicates that the inlet diameter of the pump is 50 mm (the complete model IS50-32-160 32- indicates that the outlet diameter of the pump is 32 mm). 160- represents impeller diameter.

Q:Which nuclear submarines use the shaftless pump technology?

Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.

Q:What are the failures and causes of the replacement of the fuel pump assembly?

Failure cause:1) the gasoline pump is too thick with the gasket at the junction of the axle box.2) pump film rupture or pump film and pump shell combination of sealing is not strict.3) the oil inlet valve is stuck or sealed badly.4) severe wear of the rocker arm, reducing the pump film stroke.5) the pipeline from the gasoline tank to the gasoline pump is not smooth, or the pump film spring passes.

Q:What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?

Pump downstream equipment design pressure is greater than 3MPa, if it is 400 meters, the downstream equipment design pressure is greater than 4MPa

Q:Do you have a suction pump higher than 9 meters?

This screw self-priming pump suction process can be more than ten meters or more, my family is using this

Q:What are the problems that should be paid attention to when using vacuum pumps?

What are the problems that should be paid attention to when using vacuum pumps?

Q:Filter backwash pump for what use, what is the principle of work ah?

When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
