Water ring vacuum pump working fluid recovery system

Abstract

The invention discloses a recovery system for a working solution of a water-ring vacuum pump. The recovery system comprises a RO water purifying device and a first water tank which are connected with each other, wherein a vacuum pump water inlet is connected with the first water tank through a pipeline; the vacuum pump comprises a liquefying device; a water outlet of the liquefying device of the vacuum pump is connected with a third water tank through the pipeline; two water outlets are formed on the third water tank; one of the two water outlets is connected with a second water tank through the pipeline and the other is connected with a wastewater treating device through the pipeline; three water outlets are formed on the second water tank, wherein the first water outlet is connected with the first water tank through the pipeline, the second water outlet is connected with the wastewater treating device through the pipeline and the third water outlet is connected with a cooling water device; a master controller, a solenoid valve controller and a sensor system are also arranged in the recovery system for the working solution of the water-ring vacuum pump. According to the invention, the recirculation of the working solution of the water-ring vacuum pump is realized through a set of automatic control system and the water resource is saved.

Description

technical field [0001] The invention relates to a water ring vacuum pump, in particular to a recovery system for working liquid of the water ring vacuum pump. Background technique [0002] Water ring vacuum pump is a kind of rough vacuum pump, used in many processes such as medicine and food, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum adsorption, etc. Water ring vacuum pump has been widely used. Due to the rapid development of vacuum application technology, water ring vacuum pumps have been paid attention to in obtaining rough vacuum. [0003] During the working process of the water ring vacuum pump, a stable water circulation system is required to provide it with the water flow required for its work. In the filling production line of pharmaceutical companies, the adsorption function of the water ring vacuum pump is commonly used by filling machines. The working fluid is RO cooling water.

Problems solved by technology

[0005] The drained water cannot directly enter the vacuum pump to be used as the working fluid. The reason is that the temperature rise of the vacuum pump working fluid after the equipment is running exceeds the ideal working temperature range of the working fluid. Recycling and using the working fluid exceeding the temperature rise range will affect the vacuum. Spend
