◊ 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: The water tank of the fish tank does not air out and only has the water outlet: The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.

Q: What are the application areas of pumps?: Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:

Q: How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?: For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,

Q: What is the liquid pump? What are their categories? What are their strengths and weaknesses?: The pump is constructed by connecting large diameter gas piston with small diameter hydraulic piston. The two piston area ratio produces a pressure ratio, and the maximum output pressure can be calculated by the pressure ratio. High pressure ratio produces high outlet pressure. You can set the outlet pressure through a simple gas pressure reducing valve. Pressure ratio * gas drive pressure = output pressure.

Q: What is the difference between the ground pump and the pump in the commercial concrete?: Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly

Q: Which nuclear submarines use the shaftless pump technology?: The team led by academician Ma Weiming of China is now carrying out the research on this technology and has achieved initial success.. This technology is expected to be applied to the next generation of domestic submarines.

Q: Metering pumps related matters: 1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal

Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.: If the water pressure is not enough, the pump can not start, then it must be wrong. Because if the water pressure is not enough, the pump should be running automatically. It's just because the water pressure is not enough.

Q: What flowmeter is installed after the pneumatic diaphragm pump?: The pressure decreases, the diaphragm moves slowly, and the flow decreases.This is not particularly accurate, because the diaphragm is not a metering pump, but the approximate flow can still be controlled.

Q: How to maintain and repair the booster pump of pipeline pump?: Two 、 troubleshootingfaultReasonRemoval method1. water pump does not produce waterThe water injected into the water pump is not enough, the rotation direction is not right, and the impeller passage is blocked.Pump water into the pump, pass through the impeller runner, adjust the direction of rotation.2. pump flow is insufficientThe pump speed is too low, part of the blockage, the total lift pump is higher than the rated value, the damage to the impeller.Clean the water pump and pipe, replace the impeller, increase the pump shaft revolutions, adjust the outlet valve.3. lack of outlet pressureThere is air in the liquid, the speed is too low, the impeller is damaged and the outlet valve is open.Exclude liquid air, increase the pump speed, replace the impeller, adjust the small outlet valve.
