Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump

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: Does the reservoir water heater press the booster pump (high marks)?: The outlet water pressure of hot water is the same as that of cold water. The water heater is pushed by cold water to push out the hot water. (of heating). Installation location about 2 meters away from the ground, the impact of water pressure is not large, in rural areas, the installation position in more than two buildings will have an impact. In the city, the installation position is above four floor to affect the water pressure.

Q: The main factors affecting the performance of centrifugal pumps: The low specific speed pump, on the other hand, is suitable for smaller flow and higher lift. When the pump outlet pipe diameter at the same time, if the two pumps flow similar, smaller than the speed of small head, shaft power consumption is also large. Generally speaking, the centrifugal pump with smaller revolutions than the impeller has a narrow outlet width and a large outer diameter, and the channel formed by the blade is narrow and long. If the ratio of revolutions is large, the impeller outlet is wide and the outer diameter is small, then the flow passage is short and wide.I hope my answer will be helpful to you. I hope to adopt it!

Q: What does centrifugal pump mean horizontally?: In other words, pump casing and pump body along the horizontal center of the pump leaves into the upper and lower halves, so that when the pump leaves the pump cover open, you can pump and bearings as a whole pumping out. No need to remove the pipe. I don't know. Do you understand?.

Q: Is the sewage pump the same as the mud pump?: The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.

Q: What is the liquid pump? What are their categories? What are their strengths and weaknesses?: The air driven liquid pump adopts compressed air driving method, and has the following advantages:The pressure can be adjusted by manual pressure control valve or air control valveIt is driven by air and is especially suitable for explosion protection applicationsAble to achieve pre-set final pressureAutomatic pressure relief by pumpLong term conservation without consuming energyWhen holding pressure, medium will not overheatThe utility model has the advantages of convenient installation and low maintenance cost, and only needs to connect the gas source, the inlet pipeline and the pressure pipelineReliable operation, low maintenance cost and little noise at the time of operation

Q: What are the main performance parameters of hydraulic pumps?: Main performance parameters of hydraulic pump:1. Hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.

Q: Direct connection pump What is straight pump and non direct pump? What's the difference in structure?: Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large

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.
