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: If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?: Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".

Q: What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?: Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.

Q: Variable flow pumps are variable pumps: Variable input speed, the pump out of the flow is variable, it can not be said that it is variable pump.In a word。 A variable pump is a variable displacement pump.

Q: How to install, operate and maintain the pipeline booster pump?: When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.

Q: I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!: 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: Is the flow meter in front of the pump or after the pump?: After the pump, the reasons are as follows, before the pump, you pump fluid through the pump will produce negative pressure in front of the pump, negative pressure on the flow of the life of the impact, the pump will not, Suzhou first Chi meter

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: Metering pumps related matters: 1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal

Q: What flowmeter is installed after the pneumatic diaphragm pump?: According to your entire pipeline system to flow meter ah!How about the pressure, the material, the digital float or what?You must be sure of the size of the flow
