Q:What is the difference between centrifugal pump and self suction pump? Which is better?

If the centrifugal pump in full before the start of the shell of the gas, then start after the center of the impeller was thrown in the gas can not be large enough to form the vacuum, so that liquid in the bath can not be sucked, so the centrifugal pump to start before using foreign liquid in the pump housing space filling

Q:What should be used to pay attention to the use of mechanical pumps?

Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test

Q:What is the dry running protector of screw pump? What's the principle and function? Thank you

The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air

Q:What does centrifugal pump mean horizontally?

Centrifugal pump horizontal opening meaning: pump shell and pump body along the pump blade horizontal central line is divided into the upper and lower halves, so that the maintenance of pump leaves when the pump top cover can be separated from the pump and bearing as a whole. No need to remove the pipe.

Q:What are the causes of pump shock?

6., water pump relatively serious cavitation, improve the water level of the water tank, reduce water output7., impeller and motor rotor imbalance, overhaul8. pump shaft bending or abrasion overhaul

Q:What's the difference between non negative pressure and variable frequency water pump?

No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure

Q:Does vacuum pump oil belong to dangerous goods?

Absolutely not. We often send oil by express or by freight. There are no problems at all. Don't be afraid, don't burn, explode

Q:Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?

Different working conditions, our company does dry claw pump alone can also achieve the vacuum of 133 PA.

Q:What's the difference between a concrete pump and a concrete pump truck?

Concrete conveyor pump height and distance can reach hundreds of meters, which is far more than pumping vehicles, but it needs cloth tube, not flexible enough. Less investment.Pump car use more flexible, higher investment.

Q:Attention should be paid to the use of pumps?

1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
