The use of water ring vacuum pump needs to maintain a certain vacuum degree, which needs to be equipped with a vacuum gauge to observe the pressure of the system. It is part of the negative pressure device. In order to make you better understand the configuration of negative pressure device, next I will tell you what the typical configuration is.
1. The water ring vacuum pump set is mainly composed of two 2bv6-061 water ring vacuum pumps and a set of working liquid circulation system of liquid ring vacuum pump, which are connected with pipes, instruments and valves. A check valve pneumatic butterfly valve is set at the inlet of the water ring vacuum pump to prevent the backflow of working fluid due to the sudden shutdown of the water ring vacuum pump, thereby affecting the pump system and roots pump. The pressure transmitter is set at the inlet of the liquid ring vacuum device and connected to the user programmable controller system to monitor the system pressure.
2. At the same time, a vacuum gauge is also provided to observe the system pressure on site.
3. A filter screen is set at the inlet of the pump set to facilitate the user to install the pipeline and avoid the entry of particles or dust in the equipment from affecting the start-up.
4. The pump set is equipped with return pipe and stop valve to facilitate the regulation of system pressure.
5.2bv water ring vacuum pump uses methanol as working fluid. When in use, the working fluid is injected into the vapor-liquid separator to the normal liquid level, and the water ring vacuum pump opens the working fluid water supply valve.
6. The working liquid enters the water ring vacuum pump. After being compressed by the water ring vacuum pump, the inhaled gas and working liquid enter the gas-liquid separator installed on the side. The gas is discharged into the tail gas recovery condenser through the exhaust port on the top of the separator. The condensed gas enters and is sent to the relevant pipeline. The working liquid is cooled by the condenser and then recycled.
7. The gas-liquid separator is equipped with a magnetic flap liquid level transmitter, which can display and remotely monitor the working liquid level on site. At the same time, control the opening of the pneumatic ball valve for water replenishment.
The components of the negative pressure unit of 2BV water ring vacuum pump are important components of the vacuum pump. Therefore, for the negative pressure unit, its components need to be in good condition to ensure the basic performance of 2BV vacuum pump.
