2BV series Liquid ring vacuum pump

Products

一、Product description of 2BV water ring vacuum pump:

2BVvacuum pumps and compressors system by the vacuum pump, compressor, motor, gas water separator line. 2 bv the working process of the vacuum pumps and compressors and gas water separator is as follows: gas by pipeline is entered into the 2 bv vacuum pump or compressor valve, and then through the exhaust pipe in the gas water separator, the bullishness of water separator exhaust pipes. When used as a compressor, the gas-water mixture discharged by the compressor is separated in the gas-water separator, and the gas is transported to the system that needs to be compressed by the valve. 2 bv the work of the water in the vacuum pump or compressor is by air without cooling water separator to the vacuum pump to use, the rest of the work of water by the water supply pipe, the size of the water supply, by the valve to adjust the water supply pipe.

The difference between gas suction and pressure delivery system is only that the internal structure of the gas-water separator is different. When pumping gas, the suction pressure is lower than atmospheric pressure, while the outlet pressure is equal to atmospheric pressure, and the air and water separator has overflow pipe. Compress gas, inspiratory mouth for atmospheric pressure (or vacuum), vent pressure is higher than a atmospheric pressure, in order to ensure the conveying gas pressure, gas water separator of water through the overflow water switch to control.

二、Use and scope of 2BV water ring vacuum pump:

The 2BV series water ring vacuum pump is a single-stage pump with integral structure - machine pump. Shaft seal adopts mechanical seal with simple structure, simple installation, no oil, safe and reliable.

2BVseries water ring vacuum pump suitable for pumping gas and wet steam, inspiratory pressure can be up to 33 mbar absolute pressure (vacuum) 97%, when 2 bv water ring vacuum pump suction pressure is less than 80 mbar long-term work, should join cavitation protection tube to the pump, 2 bv water ring vacuum pump, such as air ejector suction pressure can reach 10 mbar, sprayer can be installed directly on the vacuum pump suction mouth, used as a compressor, its maximum pressure 0.26 MPa (pabs).

2BV series water ring vacuum pump and compressor are widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields. Since the compression process of gas is isothermal during the working process, it is not easy to explode when the gas is compressed and pumped, so its application is more extensive.

三、Working principle of 2BV water ring vacuum pump:

2BVwater ring vacuum pump because in the process of work, the work is done to generate heat, hot water ring, jobs at the same time, some of the water and gas is weeks together, therefore, in the process of work, must constantly to pump water, supplemented by cooling and the consumption of water in the pump, the pump work requirements.

When 2BVwater ring vacuum pump exhaust gas is no longer used, on the 2 bv water ring vacuum pump exhaust wind water separator, waste gas and part of water into the air after the water separator, gas water separation, gas from the exhaust pipes, leave the return pipe of water supply to continue to use inside the pump. With the extension of working hours, the working temperature of the water will continue to rise, then need to supply cold water from the pipes, in order to reduce the work of water temperature, to ensure that the pump can achieve the required technical requirements and performance indicators.

When 2BVwater ring vacuum pump used as compressor, pump outlet wind water separator, air water mixture into the gas water separator automatically after points, gas from the exhaust pipe to the required system work after water separator to come within 2 bv water ring vacuum pump. When compressed gas, the working water is extremely hot, the water is discharged from the pump exhaust outlet, the temperature will be higher, and the water supply pipe should be continuously supplied with cold water. In order to replenish the water that is released, the cooling effect of the working water will not be too high, so as to ensure the performance of the compressor, danone technical indicators and full process requirements.
