Q:What is a water pump coupling device?: The automatic coupling device of the water pump coupling device has compact structure and small occupation area. The sump pump works because it is submergedThe utility model can be directly installed in a sewage pool, and no special pump house is needed to install a pump and a machine, thereby saving large amounts of land and infrastructure expenses

Q:Is the centrifugal pump large or small?: NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.

Q:What is a gear pump for?: Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.

Q:What should I pay attention to when buying a pump?: Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.

Q:How is the pump level of submersible sewage pump determined?: Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level

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 is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you: There are many ways to change the variable pump flow: by changing the eccentricity to change the piston stroke length (radial piston pump, the frequency change principle) motor speed to adjust the flow (such as gear pump flow control principle).

Q:What are the differences between the sewage pump and the clean water pump?: The main difference between the sewage pump and the clean water pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.

Q:Water pump can not be pumped out, how to maintain water?: Severe vibration of water pumpIt is possible that the rotor is unbalanced, or the coupling is not good, the bearing is worn and bent, and some parts may be loosened and broken. They can be adjusted, repaired, strengthened or replaced separately.

Q:Piston filling and peristaltic pump filling which precision is high?: First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section
