Q: How about the depreciation of vacuum pumps?: (five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.

Q: What are the general water pump failure, how to repair?: Troubleshooting of water pumpFirst, the water pump does not cause water analysisThere is air in the inlet pipe and pump body(1) before the water pump is started, the water is not filled enough. Sometimes it seems that the water has been discharged from the vent hole, but the pump shaft is not rotated. The air is completely discharged, resulting in a small amount of air remaining in the inlet pipe or pump body.

Q: How does the centrifugal pump pump and cut the pump?: Check the motor, pump and fasteners in good condition; whether the lubricant is added or not;Disc dynamic coupling, whether or not stuck phenomenon;Open the inlet valve, remove the gas in the pump or pump the gas out of the pump;

Q: Water pump can not be pumped out, how to maintain water?: The pipe leaks or leaks:The nut may not pinch well when it is installed. If the leakage is not serious, it can be coated with cement or mixed with asphalt oil in the places where the gas leaks or leaks. Temporary repairs can be done with wet mud or soft soap. If the leakage at the joint, you can tighten the nut by hand. The leak is critical and must be re assembled.

Q: Does vacuum pump oil belong to dangerous goods?: Is the grease inside? How could it be dangerous goods? Absolutely not!

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: The main factors affecting the performance of centrifugal pumps: Revolutions required to have. It has the following meanings: 1, similar to the geometry of centrifugal pump, everywhere efficiency at the top of the similar condition; centrifugal pump 2, than the number of different, its geometry must be different than the number; the same pump, its shape is similar, but does not rule out the shape similar situation. The following factors are related to specific speed. The specific speed of centrifugal pump has nothing to do with the nature of the conveying fluid, but has a close relationship with the shape of the impeller and the performance curve of the pump. The pump with high specific speed corresponds to the highest efficiency when the flow rate is large and the head is small

Q: What is the working pressure of the hydraulic pump in the hydraulic transmission system?: The choice of pressure depends on the size of the load and the type of equipment. Consideration shall also be given to the assembly space, the economic conditions and the availability of components for the actuators.In the case of a certain load, low working pressure, is bound to increase the structure size of the actuator on some devices, the size must be limited, from the perspective of material consumption is not the economy; on the other hand, the pressure to choose too large, the pump, cylinder, valve and other components of the material, sealing and manufacturing accuracy requirements very high, must raise the cost of equipment.

Q: How many square cables does the submersible pump for 7.5KW need?: According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.

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.
