◊ Application

RS Series vacuum pump is compact, light and attractive in design. It uses the big starting torque and is specially designed for low temperature environment. It is guaranteed start normally in winter’s low temperature. It is applicable to vacuum packaging, vacuum freez

This kind of pump is widely used in food packaging, scientific research, medical treatment, electronics, chemicals, medicine and laboratory of universities and colleges.

ing, automobile reparation, gas analysis, medicine mechanism, printing mechanism and other vacuum evacuations.

◊ Technical data

◊ Products' picture

Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: 1) oil rotary vane vacuum pump is too low, no effect on the oil seal exhaust valve, rotary plug to refuel after large exhaust sound, and oil mist, that the level is too low, the gas can be eliminated.(2) the vacuum caused by the condensable steam pollution of oil should be changed, and new vacuum pump oil should be replaced.

Q: 5 floor water pressure is too low, what kind of water pump is better?: The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position

Q: What are the ways of hydraulic pumps?: Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.

Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?: When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal

Q: What are the basic technical parameters of the pump?: Two, pump head H head is the unit weight of the liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid. Habits referred to as meters. Three, the pump speed is n RPM pump unit time revolutions, represented by the symbol n, the unit is r/min. four, the pump NPSH NPSH NPSH is also called net positive suction head, said main parameters of cavitation performance. Cavitation has been used a h power of five, the power of the pump. And the efficiency of the pump is usually refers to the input power, which is the prime mover on the pump shaft power, it is also known as the shaft power, denoted by P;

Q: Is the sewage pump the same as the mud pump?: Two of the main performance parameters of mud displacement and pressure, displacement from a number of liters per minute, with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger aperture, the greater the displacement. The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.Sewage pump is mainly used for industrial wastewater treatment, sewage treatment, environmental protection has played a big role. Among them, the sewage pump is also a sewage pump with cutting wheel, such sewage pump can be chopped dirt, and then extract the sewage clean.

Q: Working principle and structure of external gear pump: When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, and the pressure is lowered, and the liquid in the suction pipe is sucked into the pump; the suction liquid is divided into two parts to be pushed into the discharge chamber by the gear in the alveolus. When the liquid enters the exhaust chamber, the liquid is squeezed and discharged from the exhaust chamber into the discharge pipe because the teeth of the two gears are continuously engaged. The driving gear and the driven gear keep rotating, and the pump can continuously inhale and discharge the liquid. The pump body is equipped with a safety valve, when the discharge pressure exceeds the required pressure, the delivery liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe.

Q: Harm of air pump and pump: Centrifugal pump situationEmpty pump is divided into two kinds, if there is no liquid, then it will cause the mechanical seal of the pump to overheat, wear and even die

Q: Suction stroke and lift of water pump: For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.

Q: What are the failures and causes of the replacement of the fuel pump assembly?: Failure cause:1) the gasoline pump is too thick with the gasket at the junction of the axle box.2) pump film rupture or pump film and pump shell combination of sealing is not strict.3) the oil inlet valve is stuck or sealed badly.4) severe wear of the rocker arm, reducing the pump film stroke.5) the pipeline from the gasoline tank to the gasoline pump is not smooth, or the pump film spring passes.
