All of our pumps have got CE certificate and exported to Italy,Astralia ,America,Indonesia and the kind.
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.

Q:Troubleshooting of diaphragm pump
The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture
Q:What is the distance between the pump and the wall?
What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Centrifugal pumps require a vacuum to produce negative pressure, which allows atmospheric pressure to lift the water surfaceAxial flow pump impeller is thrust on water
Q:How about the depreciation of vacuum pumps?
(three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;
Q:How can I buy a pump?
Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.
Q:Is the vacuum pump air compressor?
No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
Q:What is pump suction work?
In the ventilation process, pump suction is formed. The ventilation process is the whole process from opening to closing of the exhaust port. Pump Qigong refers to the cylinder gas on the piston in the forced exhaust stroke and suction stroke done by the work
Q:Any center of the pump
Alignment methods and requirements:1, check two feeler dial gauge or flange coupling the parallelism, usually with clearance between the both ends of the side instead of difference, in the circumferential direction every 900 measure, the maximum and minimum gap gap difference (Ab) less than or equal to 0.3 mm.2, the coupling flanges outside the park up and down, left and right four position to check whether they are in the same line, C less than or equal to 0.1 mm.When looking for a positive C, it will affect (a - b), finding the right (a - b) will affect the C, to balance each other. It's easier for an unskilled comrade to find C (a - b) first, and then find a positive one. Through the adjustment of the motor at the foot of the gasket thickness (Ab) and meet the requirements of C.Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition.It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
Q:The function of centrifugal pump
The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearing, sealing ring, stuffing box.1, the impeller is the core part of the centrifugal pump, it is high speed, large output, the impeller blade and play a major role in the impeller before assembly, through the static equilibrium experiment. The inside and outside surfaces of the impeller are required to be smooth, so as to reduce the friction loss of the water flow.
Q:Why should I pump the pump before starting the centrifugal pump?
1., if it is backward flow, it is not pumping;2., if the pump is installed underwater (such as submersible sewage pump), it is not pumping;3. pump is for installation in the form of suction. If no diversion irrigation pump, then the pump is full of air quality, air density is less than water, the pump will not be inside the gas out, the pump pressure will not be far less than the atmospheric pressure, the water will not be pressed into the pump to pump through irrigation formed inside the closed environment, the pump will start water out will cause local vacuum, entrance external water pressure into the pump is in inside and outside differential pressure, complete water movement. (vacuum water diversion is directly through the vacuum pump pumping the air in the pump, resulting in internal and external pressure difference, the external water pressure in the internal and external pressure is press into the inlet of the pump. The principle is the same as the pump. A standard atmosphere of =10m water column.)
