The water ring vacuum pump is the most popular vacuum equipment used in vacuum pumps. It is mainly sealed by the liquid ring formed by water. The extracted gas will take away part of the working fluid. The gas-liquid separator is the part of water and gas. Separation. The separated water is then returned to the pump body through the heat exchanger to realize a closed cycle of the vacuum pump working fluid.
The inlet of the water ring vacuum pump gas-liquid separator is connected to the exhaust port of the vacuum pump. After the vacuum pump and the part of the water are discharged into the gas-liquid separator, due to the different density of the gas and the liquid, when the liquid and the gas mix and flow together, if the blockage is encountered, the gas will bounce away, and the exhaust pipe discharge. The liquid continues to have a forward speed due to inertia, and the forward liquid adheres to the barrier wall and is brought down by gravity, and is discharged or returned to the vacuum pump for circulation. When the working time of the vacuum pump is prolonged, the temperature of the working fluid will continuously increase. At this time, a certain amount of cooling water is added to the vapor-liquid separator to reduce the temperature of the working fluid, and the pump can meet the required technical requirements and performance indexes.
The water ring vacuum pump can also be used alone without a gas-liquid separator. The gas-liquid separator is arranged to facilitate the recycling of the working fluid of the vacuum pump. If the working fluid contains substances with recycling value, the working fluid is toxic and harmful and cannot be directly discharged, and the working fluid is insufficient to be recycled.
The water ring vacuum pump and the gas-liquid separator are used together to reduce environmental pollution, save water resources, reduce the generation of sewage, save sewage treatment costs, and prolong the service life of the vacuum pump. In addition, the separator can also eliminate the noise generated when the water ring vacuum pump is running, so it is also known as the silencer.
Everyone should pay attention to the following items when installing the gas-liquid separator of the water ring vacuum pump: (1) The vapor-liquid separator should be installed in the specified position according to the outline drawing; (2) The connecting line between the vacuum pump and the separator should not be too long. . If the pipe is too long, the possibility of leakage in the middle increases. In addition, if the pipeline is too long, the pump's outlet resistance will increase, which will reduce the pumping capacity and vacuum of the pump and increase the power consumption. (3) The connecting pipeline can not be turned too fast, and the turning is too fast, which will cause a greater workload on the vacuum pump. . (4) The flange end face of the connecting pipe shall be sealed with asbestos pad and shall not leak air; (5) The pipe supplying water to the water tank and the water supply pipe of the stuffing box may be connected together.
The installation of the gas-liquid separator of the water ring vacuum pump cannot be ignored. Everyone must handle it according to the actual working environment and working conditions to achieve the best working results.
