◊ Application

This series of pumps are elementary equipment for pumping air from sealed vessels. It can be used alone, also can be used as the forepump, process pump or titanium pump of booster pump, oil diffusion pump, and molecular pump. It is applicable to vacuum coating, vacuum heat treatment, vacuum smelting, vacuum tube, bulb, refrigeration, chemicals, packing, forming, health and medical appliances, laboratory, vacuum drying machines and vacuum filtering.

◊ Technical data

Q: How can the submersible pump level meter be connected?: Install liquid level controller, two position liquid level sensor, controller to buy manual, wiring according to wiring diagram.

Q: 5 floor water pressure is too low, what kind of water pump is better?: Pipe blockage, leaks, or throttling devices are not opened. This can be tested on a pipe with a pressure gauge;Water pump is equipped with power source, power or speed does not match, check the pump and power end nameplate, power end of the pump power is generally 1.1.5 times;

Q: What is the pump, how to classify, mainly used in where?: Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump

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: Advantages and disadvantages of centrifugal pumps?: The uniform liquid no pulse phenomenon.(2) shortcomingsBefore running, the pump must be filled with liquid.For the supply of small flow, large pressure head inappropriate, inefficient and limited.Encountered imperfect design or operation is not at the time, such as milk, it is easy to produce foam, affecting the next process production.The installation is wrong. There will be "Qi tie" phenomenon.The efficiency is also lower than the reciprocating pump.The sources of knowledge are absolutely reliable!!!!

Q: There are second cutting, third cutting, why three times?: I used to do this job before. After the impeller is cut, the flow and lift will decrease. Sometimes, the same pump will be cut according to the needs of the impeller, so as to meet the actual needs, at this time, with the power of the motor will also be reduced

Q: What are the application areas of pumps?: 1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system

Q: What is the pumping property of concrete?: Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement

Q: Why is the sewage pump device coupler?: The automatic coupling device but the installation of GAK type submersible sewage pump, need lifting, people may not need to unscrew the screw water, the water pump can directly improve, after repairing down along the guide rail can realize sealing pump and pipeline, water pump and normal operation. Small sewage pump can be installed freely, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.

Q: What is the difference between an air pump and a water pump?: A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.
