Q: What is a gear pump for?: Oil pump casing wearIt is mainly the wear of the floating sleeve hole (the normal clearance between the gear shaft and shaft sleeve is 0.09~0.175mm, and the maximum shall not exceed 0.20mm). The gear work is affected by the pressure oil, the gear tip is close to the oil pump casing, and the low pressure chamber part of the pump body is worn. Another kind of wear is the circumferential wear of the work surface in the shell. This kind of wear is mainly caused by the addition of oil which is not clear, so the oil without impurities is necessary.

Q: How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?: For example: water storage is relatively small, it needs to reduce the temperature of the heat exchanger. If the tank is relatively large, it does not need cooling water circulation pump again when the temperature is very low, there is no need to heat exchanger. So you need to ask how much water this is not OK.In a soda separator problem:

Q: What are the causes of pump shock?: Troubleshooting cause1. bearing damage, replace new bearings2., coupling pin, bolt damage, rubber column or metal bolt wear, change

Q: The distance from the pump button to the ground: Yellow warning pop-up, indicating that the fire control room has issued alarm information, fire alarm controller (commonly known as the alarm host)

Q: What kind of motor does the hydraulic pump need?: Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element. Hydraulic pump according to the structure is divided into gear pumps, piston pumps, vane pumps and screw pumps.

Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?: Installation method of hydraulic pump(1) according to the technological requirements and the cavitation conditions of the pump, the installation height check and the civil engineering of the foundation are carried out.(2) prepare a series of flat washers and wedge gaskets of different thickness before installation.(3) according to the characteristics of the pump conveying medium, determine the material of the gasket at the connection and process the gasket.

Q: Why does the centrifugal pump start and close first when the outlet valve is closed?: The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,

Q: What are the main performance parameters of hydraulic pumps?: Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.

Q: The working principle of magnetic pump: Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.

Q: What are the failures and causes of the replacement of the fuel pump assembly?: Gasoline pump is the gasoline from the gasoline tank suction and the gasoline tank has a certain pressure, thereby, it overcome the resistance of the pipeline, pipeline and fuel filter into the carburetor float chamber or electronically controlled injection engine in the guide frame.
