1.performance as transfer pump or booster pump in oil delivery system
2.Applied as fuel pump for delivery system
3.Pressurization and injection in fuel supply system
4.All industry fields as lubricating pump
The heat treated gears have the advantage of higher hardness and intensity,and rotate with the axles inside the replaceable bearing sleeves. Design with leakage and return chute,which lets the gears bear the least torque force and reduces load and wear on bearings in order to raise pump‘s efficiency.
Gears,axles,Pump body,pump cover,safety valve and Axles-end seal etc.

Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Large pump control valve controlled energy consumption at least 30% reason is that there are serious throttling loss of a throttle valve control system of severe fever but simple structure and low cost which is why now valve control system still occupy the main market reasons.Pump control system with complicated structure especially when serious nonlinear control unsymmetrical cylinder control effect is not ideal, but the biggest advantage is energy-saving and low fever America professor Monika points out that using the pump control system of hydraulic excavator energy efficiency compared with the valve control system can be improved by over 46% but costs are high. But in control, the three pump invented by Professor Quan LONG of China is a good solution. LZ can find the invention patent or find his paper on sage. It seems that there are three or four SCI about this pump
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:How accurate is the metering pump?
In addition, when the oil supply is too large or the pipeline pressure rises unexpectedly, the volume of the liquid in the hydraulic chamber can be changed, thereby affecting the stability of the flow and reducing the metering accuracy of the pump. In order to solve the problem of how to stabilize the measurement accuracy of metering pump metering pump flow, how stable, the three valve device. The so-called actual refers to the combination of three functions including compensation, discharge and safety protection device or device supporting the hydraulic chamber, according to its action principle is different, is divided into automatic compensation and forced compensation two three valve device.
Q:What flowmeter is installed after the pneumatic diaphragm pump?
The pressure decreases, the diaphragm moves slowly, and the flow decreases.This is not particularly accurate, because the diaphragm is not a metering pump, but the approximate flow can still be controlled.
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value
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:Fire pump and shower pump flow head selection, high resolution.
3, larger than 25000, the minimum water consumption of indoor fire hydrant is 20L/s4, the minimum water consumption is the flow of a fire hydrant.
Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.
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's the difference between non negative pressure and variable frequency water pump?
No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure
