The liquid ring vacuum pumps and compressors of 2BE series are high-efficient and energy-saving products developed by our company on the basis of our scientific achievements and production experiences over the years combining with the advanced international technique of similar products. They are usually used to suction the gas without solid particle, undissolved and noncorrosive gas in order to form negative pressure in the closed container. By changing the fluid parts material, they can also be used to suction corrosive gas or use corrosive liquid as operating liquid such as the PPS thermal spray coating obtained national patent.

These single-stage and single-acting pumps are simple in structure, convenient in maintaining, reliable in operating, efficient and energy-saving. They can run under tough working conditions with large drainage discharge and changing load impact. 2BE vacuum pumps adopt unique flexible discharge structure for their exhaust systems. Each valve plate is covered on vents in outer side of a port plate and fixed by a stainless steel baffle at its other side. Curvature of the valve plate changes with inlet pressure so that pumping medium can be discharged when it reaches the inlet pressure. Such structure avoids over-compression in a vacuum system and automatically adjusts exhausting area to lower power consumption, thus a best operating efficiency can be obtained.
2BE series products are applied in the chlor-alkali industry mainly to hydrogen compressor package unit of ion-exchange membrane caustic soda, acetylene compressor package unit of PVC and exhaust gas recycle vacuum pump etc.

Specifications of water ring compressor complete unit

Water ring compressor package unit are large complete equipment developed on the basis of water ring compressor. The main pump is equipped with advanced 2BE、2SY series water ring compressor and can provide aspiring system, water system of cooling and recycle seal liquid, gas and liquid separator, instruments and meters, security alarms device and pipe valves etc. according to different using requirements. The electrical control can set several functions such as manual operation, semi-automatic or full-automatic remote control. By experiments, the large complete equipment is verified to have the ability to pumping gas under various kinds of complicated working conditions and excellent performance, meanwhile can fully ensure clients’ requirements.
2BE、2SY series water ring vacuum compressors are high-efficient and energy-saving products developed in the 1990s by our company on the basis of our scientific achievements and production experiences over the years combining with the advanced international technique of similar products.
The products are tested by national vacuum equipment quality supervision and inspection center. All the performance reaches or exceed design demand and appraised by experts, our products reach the international advanced level.

The outstanding characteristics and advantages:

The impeller material is qualified steel plate, and the blades are shaped once by stamping. The inside and outside of the wheel hub conduct machining and adopts welding process. The whole impeller conducts thermal treatment and has good balance. Therefore the problem of dynamic and static balance is solved fundamentally. Our impeller has high strength, good toughness, abrasion resistance, never broken, impact and bent resistance etc. advantages and reaches international advanced level.

According to different process, the fluid parts of the compressor can adopts many kinds of material, such as SS304, SS316 and treatments(spray coating treatment) to improve the capability of being suitable for working environment. The corrosion, washing, erosion resistance ability and anti-scale deposit ability are further enhanced.
The position of the impeller reinforce rib is away from the end face. The end face of the blades on the port plate surface scrapes the sundries between them off like a scraper in case that the sundries scale between the impeller and port plate and of the wear of port plate. The sudden shut off phenomenon can be avoided as well.

The optimization design of the port plate and molded lines of the impeller improve the stream guidance effect, enlarge the suction and discharge volume and brings high efficiency and simple structure. Therefore it barely need repair and maintenance.

Adopting wear-proof stainless steel shaft sleeve and ensure the shaft away from wear.

Shaft end of the compressor adopts reliable seal mode——mechanical seal, which can avoid leakage of operating liquid and pump gas efficiently.
Foreign import bearing has stronger bearing capability , accuracy position and service life over two hundred thousand hours, which ensure the reliability of compressor’s long term operation.

Compressor and attached device can be manufactured with ordinary or special material according to different medium.

The coupling is fixed with removable strong steel closed shield which is fastened into the bottom plate firmly.

The design and structure of each electric motor coordinate with electrical system driven device and operation maintenance. The motor is damp-proof closed.

All the equipments, including the support have capability to bear completely the force and moments of the force passed from the users connecting pipe ports.

The cooling device of the operating liquid is set according to the specific working condition and pumping capability of the compressor. Adopting heat exchanger with high efficiency and convenient repair and maintenance. The heat exchanger adopts plate type generally and the plates adopt SS304 stainless steel. Thus the closed cycle of operating liquid is achieved and save the consumption of the water.

According to the demand of working condition, the gas and liquid separator is generally provided which can separate the pumping gas efficiently and recycle operating liquid. Meanwhile, the liquid cooled by heat exchanger can replenish the recycle of operating liquid. The gas is discharged to specified place via the outlet of the separator. It’s specially suitable for pumping flammable, explosive and poisonous gas. The reliable automatic water replenishing and drainage device is correspondingly installed.

The liquid level meter in the separator that can display is magnetic flap type to be controlled by electrical magnetic valve or mechanical high-low liquid level switch. There is a DCS interface which is safe and reliable.

The package unit is provided with operating liquid drain-off pipes. When the package unit is shut down, the accumulated liquid can be drained off to specified place according to environmental requirement.

According to the process demand, the control of the electrical motor and the butterfly valve of the inlet can be set via DCS. To monitor, control and interlock all the control objects and other related systems as well as protect signal can access to DCS.

According to the process demand, the whole instrument measure and control device can be provided to make sure reliable test and control capability. The exact action of the high-low water level switch and reliable output interface can make the water ring vacuum pumps operate safely and reliably and ensure the package unit to work stable with high efficiency.

The compressor and all the accessories are supplied in complete and are installed on the same foundation support with all the accessories assembled well. Meanwhile the foundation support is set special drainage device in case of accumulated water.
