The disassembly of water ring vacuum pump is divided into partial disassembly and complete disassembly. The water in the pump shall be completely released from the drain hole and all gaskets shall be removed before disassembly. Care should be taken in handling this step. In case of damage, new gaskets of the same thickness should be replaced during assembly. Note that disassembly begins at the end of the never coupling. The water ring vacuum pump is removed in the following order. First, loosen and remove the bearing cover. Step 2, loosen the rolling bearing, use the hook wrench to unscrew the round nut and remove the nut on the packing gland. Step 3: loosen the bearing frame by the side of the left cover, and rotate two dismounting screws to remove the bearing and bearing frame from the shaft. Step 4: disconnect the inlet pipe and pipe on the side cover, and loosen the connecting screw between the pump body and the side cover and the double-headed bolt outside the pump foot. Fifth...

Water ring vacuum pump has the characteristics of vacuum transportation: compact structure, reliable balance and uniform flow. In chemical production, it is often used to transport or pump inflammable, explosive and corrosive gases. Water ring vacuum pump because impeller mixing liquid, loss of energy, so its efficiency is very low. Vacuum pump is widely used, can be used in petroleum, chemical industry, machinery, mining and many other industrial sectors, it can also be used for conveying vacuum, I do not know if you know its characteristics of conveying vacuum, the following is to introduce the characteristics of vacuum pump for vacuum transport: 1, high efficiency, equipment no return transport, other means of transport have the transport wrist are free return defect, and the transport medium is air, only in the terminal into the atmosphere, in the process of transport, the inlet can be continuous feeding, complete continuous transport. 2, the equipment has simple structure, m...

I think many friends are very interested in the excitation control of water ring vacuum pump, this is really a key and difficult work, next I will introduce some relevant content, you can read it carefully. 1. Open-loop simulation test for closed loop regulation of potential (or voltage). The simulation mode gives the armature terminal voltage and armature loop current, and sets the output limiting value, excitation current and feedback loop parameters of the potential (voltage) regulator. 2, excitation current (or flux) regulation closed-loop control of the step response to adjust the dynamic characteristics. The dynamic characteristic indexes of k should be measured and adjusted respectively in the full magnetic working area, near the starting point of weak magnetic field and the weak magnetic working area to meet the design requirements. 3. The excitation loop of the water ring vacuum pump is connected to the power supply to check and adjust the preset parameters, including th...

1, water ring vacuum pump is a crude vacuum pump, by the pump body, impeller, suction and exhaust disc, water in the pump body wall water ring, exhaust port, suction port, auxiliary exhaust valve, etc. About the two-stage pump is 0.133 ~ 0.665kPa. Water ring pump can also be used as a compressor, it belongs to the low-pressure compressor, its pressure range is (1 ~ 2)X105Pa table pressure 2. The gas enters into the water ring pump through the valve in the pipeline, and then is discharged into the air and water separator through the air guide bend, and is discharged through the exhaust pipe of the air and water separator. As tightening machine is unavailable, the tightening machine discharge of air water mixture in the gas water separation in the separation, gas through the valve walked up to the system of tight gas demand, while water in gas water separation device, for the water level adhere to certain gets water separation device is equipped with automatic water switch, when th...

In this paper, a new kind of water-based film adhesive, applied in the vacuum aluminum plating pet composite glass paper production process, the printing plant shows that the adhesive has a fast drying speed, extrusion compound process is not easy to blister, flat, smooth film surface rubber good transparency, no yellowing, had no adverse effect on printing ink and other characteristics, is an ideal water film adhesive. The emulsion copolymerization product of acrylate and vinyl acetate, the glass transition temperature is lower than 0e, the production process is simple, no need to add viscosifier and other modifiers, the ph value is nearly neutral, no corrosion to the cots. The adhesive can also be used for other laminated packaging materials, such as wine packaging box paper, laminated paper bag, printing laminated cover paper manufacturing. C vinegar vacuum aluminum plating film adhesive preparation principle of vacuum aluminum plating pet film with very smooth surfa...

Water ring vacuum pump works stably and reliably with simple operation and convenient maintenance. Although it looks light, it can be used in life. Below by small make up for you to introduce it! 1. Vacuum filtration (chemical filtration plant, chemical processing plant, iron ore plant, mining industry, phosphate fertilizer plant, paper mill, poultry processing plant, coal preparation plant) 2. Pump diversion (waterworks) 3. Steam recovery (distiller, loading station) 4. Vacuum distillation (milk factory, food factory, chemical factory, pulp factory) 5. Condenser tank refill (power station) 6. Vacuum disinfection (hospital, infirmary, laboratory) 7. Drying (chemical, pharmaceutical manufacturing) The above is small make up for you to introduce the main application areas of water ring vacuum pump, if you want to know more about the water ring vacuum pump knowledge, welcome to call our company's service hotline, we will be happy to serve you!
