◊ 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:Why can't the centrifugal pump pump the vacuum?: Condition:The pump shell must be filled with liquid under certain installation height and running without leakage.What is the phenomenon of centrifugal pump? What harm does it have? How to eliminate?)

Q:Does the reservoir water heater press the booster pump (high marks)?: If insufficient pressure really, adding an automatic booster pump in the water inlet, is feasible. Home booster pump, a basic model, to sell the place to ask the next to know, generally 200 yuan or so, traffic 0.3-1.8, 90~150 watts on it. Do not buy too large, too much power, the water will also be too large, but the water heater will not be used.

Q:Concrete pump 125 pipe wall thickness: Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q:What does "anti pump" mean in pump operation?: The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)

Q:What is the name of the day pump and ground pump? Specific introduction: People often say "day pump" actually refers to the boom pump, it also has many other name, such as pump, boom pump, concrete pump, concrete pump truck, these words are "day pump".Ground pump, in fact, refers to the pump drag pump. Therefore, to understand the difference between day pump and ground pump is to understand the difference between the boom pump and the tow pump

Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?: Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.

Q:What's the meaning of the pump head in the water pump, please advise, thank you: The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.

Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump

Q:Double floor sewage pump circuit diagram of a small problem: Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.

Q:What are the problems that should be paid attention to when using vacuum pumps?: (8) in the process of running the pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.(10) vacuum pump to stop using, first shut down valve, pressure gauge, and then stop the motor. (11) vacuum pump in the first month of work, 100 hours after the replacement of lubricating oil, oil every 500 hours after the change.(12) adjust packing gland regularly to ensure the normal condition of drip in packing room. (13) regular inspection of shaft sleeve wear, larger wear should be replaced in good time.
