Water ring vacuum unit

The vacuum system is mainly composed of multiple liquid ring vacuum pumps. When the vacuum pump is working, the tap water stored in the steam-water separator is used as the working fluid, which is recycled after being cooled by the tubular heat exchanger, and will not discharge sewage and waste oil, which meets environmental protection requirements.

Working principle (take four water ring pump unit as an example)

The vacuum system is mainly composed of 4 liquid ring vacuum pumps. When the vacuum pump is working, the tap water stored in the steam-water separator is used as the working fluid, which is recycled after being cooled by the tubular heat exchanger, and will not discharge sewage and waste oil, which meets environmental protection requirements.
There are 4 liquid ring vacuum pumps in the vacuum system, which are designed for three purposes and one backup. During normal operation, only 3 pumps can be used to meet the vacuum air consumption of all concentrators at full load. The pump is controlled automatically and manually through sensors and PLC. Pumps 1#, 2# and 3# correspond to 1# 2# 3# vacuum buffer tanks, and 4# pumps are connected to the bypass valves of 1# 2# 3# pumps. , Take 1# pump automatic operation as an example, click 1# pump automatic operation, 1# pump will automatically start, when the set time reaches the vacuum range, it will keep running, after a period of time above the upper limit of the vacancy range (adjustable ) 1# pump automatically stops, when the vacuum pump drops to the lower limit, 1# vacuum pump automatically starts; if the lower limit of vacuum is not reached within a period of time (adjustable), start 4# pump, and at the same time 4# pump and 1# pump Open the pneumatic valve between the two pumps until it is higher than the upper limit of the vacuum range. The two pumps stop at the same time. Pump 2# 3# runs in the same way as pump 1#.
The gas sucked by the system is discharged after being washed inside the vacuum pump. It is clean and meets environmental protection requirements.
The function of the steam-water separator is to separate the gas and water discharged from the liquid ring vacuum pump and store the water for recycling.
The function of the vacuum buffer tank is the vacuum at the inlet of the buffer ring vacuum pump and the function of separating some impurities in the inhaled gas.

Features：

Economical and energy-saving: automatically increase or decrease the number of operating vacuum pumps when the vacuum load of the system is peak, normal, and low, economical and energy-saving.
Rugged and durable: high-quality liquid ring vacuum pumps from Siemens. The standard configuration of the pump is that the impeller is 304 stainless steel and the pump body is 304 stainless steel; it is not easy to rust, corrode and abrasion, and is durable. Under the same working conditions, the replacement cycle of wearing parts is longer, the performance of the whole machine is more stable, and the service life is longer. The comprehensive quality of the vacuum pump has completely surpassed similar products of international brands.
Safe and reliable: The vacuum pumps are mutually backup, and normal production will not be affected when a single pump fails or is repaired.
Clean and environmentally friendly: The working fluid of the liquid ring vacuum pump is recycled through the circulating water system, with no pollution and no emissions, clean and environmentally friendly.
Easy to maintain and repair: The liquid ring vacuum pump has no conventional wearing parts. Under normal operating conditions, there is no need to replace any wearing parts within one year and no overhaul within three years. Several small liquid ring vacuum pumps of the same model are light in weight, small in size, easier to assemble and disassemble, and more convenient to maintain. Because the parts are completely interchangeable, a set of spare parts is sufficient.

typical application：

Vacuum distillation and crystallization in the chemical industry; vacuum concentration, drying and crystallization in the pharmaceutical industry; food freeze-drying and physical refining of edible oil; electronic circuit board pressing; vacuum degassing in the building materials industry; polyester chips in the textile industry.
