Paper Machine Water/Liquid Ring Vacuum Pump

Product Description

Liquid Ring Vacuum Pump

Liquid ring vacuum pumps are rotating positive displacement machines providing process vacuum in industrial applications such as chemical, electrical power, environmental, food & beverage processing and packaging, marine, mining, oil & gas, pharmaceutical, pulp & paper and textiles. These types of pumps utilize water or other process compatible liquid as the sealant. The simple operation, with no contacting parts, make liquid ring vacuum pumps a safe and reliable choice for handling dirty and potentially dangerous gas streams.  Liquid ring pumps are available in single and dual stage designs and also configured as compressors for even more versatility.

2BE Series

                                                                                               2BV Series

 

Principle of Operation

The seal liquid forms the ring inside a pump body as the impeller spins creating small chambers for gas to be trapped. The axis of the rotor is eccentric from the body allowing the liquid to almost fill, and then almost empty each rotor chamber during a single revolution, forming the compression of the gas for the pumping action. Vacuum inlet and atmospheric discharge ports provide flow paths for the gas mixture being handled. Heat of compression of the gas is dissipated into the seal liquid, and some of the liquid flows out to discharge. The exhaust gas and residual water discharge is separated from the gas stream and directed to the house exhaust and returned to the pump respectively.  Seal fluid is replaced by a constant flow of cooler makeup seal fluid.  

Application and Features

The water ring vacuum pumps and compressors is usually used to aspirate gases that don't contain solid particle,non-dissolves in water.non-corrosiveness in order to form vacuum and pres-sure in closed container.Through changed structure material,it is too used to aspirate corrosive gases or act corrosive liquid as the working liquid.It is widely used in paper-making,chemical industry, petrification, pharmacy, light industry,foods,metallurgy,building,electrical equipment,coal cleaning,fertilizer, etc.

Welding impellers are used,blade are machining by primary punch mould with rational moulded lines. All hub are machined, so solved fundamentally the issue of dynamic balance.Impeller and pump shaft are machined by  head assemble interface fit with reliable performance, stable running. impeller ere heat treated after welded, the blade have excellent tenacity to be assured impact resistance and bending resistance.
2BEA,2BECseries pump with gas and water separator, many places set up aspirating and exhausting holes,pump cover set up exhausting valves, check and repair window. The gap between impeller and distributing plate are adjusted by gland of two ends of locating bearing. Installation and use are convenient, operations are simple,the maintenances are convenient.
