◊ 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: Fire pump and shower pump flow head selection, high resolution.: Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s

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: What are the internal losses in centrifugal pumps? How did they come about?: Volume loss: loss due to leakage;3. mechanical loss

Q: What is the Rhodes pump?: Best answerRoots vacuum pump (referred to as: Roots pump) refers to the pump is equipped with two opposite direction of synchronous rotation of the leaf rotor, rotor, rotor and pump housing between the walls of a small gap and no contact with a variable capacity vacuum pump.Roots vacuum pumps have been tested for long time in the fields of petroleum, chemical, plastic, pesticide, steam turbine rotor dynamic balance and aerospace simulation, so it should be popularized and applied in china. It is also widely used in petroleum, chemical, metallurgical, textile and other industries. Vacuum pump fittings are used for noise control of vacuum pumps, vacuum pump silencers.

Q: What does "anti pump" mean in pump operation?: Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen

Q: Pump unloading in hydraulic transmission,: Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving

Q: Brief description of centrifugal pump on / off operation: Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.

Q: What are the constant pressure pumps?: Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.

Q: Do you have a suction pump higher than 9 meters?: Pump rated suction generally 7 meters or so, it is estimated that no one calibration pump suction stroke 9 meters. Calibration suction range of 9 meters is not reliable.

Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?: Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
