Explosion-proof water ring vacuum pump

Water ring vacuum pump overview

(2bv series vacuum pump suitable for pumping gas and water vapor, suction pressure and 33 mbar pabs vacuum degree (97%), when the vacuum pump suction pressure is less than 80 mbar long-term work, gas corrosion protection tube connected to the pump, such as air injector, inspiratory pressure can reach 10 mbar, sprayer can be installed directly on the vacuum pump, a compressor, the pressure to 0.26 MPa (pabs). Water ring vacuum pump and compressor are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields, because in the process of work, the gas compression process is isothermal, so in the compression and suction of flammable and explosive gas, not easy to occur dangerous, its application is more widely.

Water ring vacuum pump structure and characteristics

Pump coaxial design, save space, easy to install.
The use of mechanical seals as a standard configuration, eliminating leakage, easy maintenance.
Smooth operation, noise can be as low as 62 db
Uniform corrosion resistance design, bronze impeller to improve the corrosion resistance of the pump, stainless steel is more suitable for more demanding applications
The unique flexible exhaust design ensures that SKA is efficient within its performance range without over – compression.

Explosion-proof water ring vacuum pump is widely used

Water ring vacuum pump and compressor are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields, because the compression process of gas in the process of work is isothermal, so in the compression and suction of flammable and explosive gas, not prone to danger, its application is more widely.

Water ring vacuum pump equipment installation

1, pump installation: vacuum pump and compressor in the installation, the installation surface must be horizontal, and through the hole in the bottom corner with bolts installed firmly. To prevent welding slag from entering the vacuum pump during installation, suction should be used during installation

2. Installation of water separator

The gas-water separator can be installed directly on the vacuum pump exhaust port and fixed firmly with bolts. The gas-water separator has a pipeline connected to the pump, thus supplying the water required for the pump work. The rest of the working water is supplied by the water supply pipe, and the water supply volume is regulated by the valve on the pipeline. The suction pipe of the vacuum pump or compressor shall be equipped with a check valve to prevent the water in the vacuum pump or compressor from returning to the system under the pressure of the exhaust pipe during the shutdown.

Water ring vacuum pump start and stop

Before long-term stop operation, fan impeller blade must be turned to verify whether there is a stuck phenomenon of 2BV water ring vacuum pump.

Starting technology of water ring vacuum pump:

1. Close the inlet valve;

2. Open the vent valve;

3. Pour a small amount of water into the pump, and refer to the water consumption in the technical index table;

4. Start the motor;

5. Open the inlet valve;

6. Adjust the water supply so as to consume a small amount of water and ensure the technical index of the pump.

The water ring vacuum pump shall be shut down in the following order:

1. Close the inlet valve;

2. Turn off the motor and stop the water supply

3, release the residual water in the pump body.

Water ring vacuum pump maintenance

1, in order to avoid wear impeller, pump body or stuck in the main impeller, with the gas and working fluid into the pump chamber of the dust particles, can be washed away through the pump lower rinse port.

2, if the use of hard water working fluid, must be soft, or in a certain period of time with the solution to clean the pump.

3, the normal work of the motor bearing is higher than ambient temperature 15 ℃ ~ 20 ℃, high does not allow more than 55 ℃ ~ 60 ℃, the normal work of bearing loading should be 1-2 times a year, cleaning bearing at least once a year, and replace all lubricating oil.

4, the use of mechanical seals, leakage phenomenon, should check the mechanical seal of the dynamic, static ring has been damaged, or the sealing ring has been aging, such as the above situation, need to replace the new parts.
