2BV Single Stage Vacuum Pump

• Model NO.: 2BV
• Specification: SGS, ISO9001

• Trademark: AOLI
• Origin: Shanghai, China

2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i. E. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i. E. 99 % vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump.

When the compressors work, the maximum pressure is 0.26MPa(abs). And the higher of discharge pressure, the larger of the power of the compressors. So it is necessary that the data of the discharge pressure is provided to choose the proper motor.

2BV series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.

2BV6 water ring vacuum pump/compressor (pump's material is stainless steel)

2BV2-Ex, 2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series products.

2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.

According to the working situation, the material of all the parts where the liquid flows (i. E. Pump casing, pump cover, port plate, impeller)are made of various stainless steel as bellow:
SUS304(0Cr18Ni9)
SUS316(0Cr17Ni12Mo2)
SUS316L(00Cr17Ni14Mo2)
The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John Crane products and the seals material is optional for FPM or PTFE.

The data below is a part of our products,we can choose the perfect pump for you according to your requirements.

Cylinder Or Power Steering Cylinder

The main components of power steering system are power cylinder, control valve and steering machine. Power steering systems are classified according to the arrangement of these components.
(1) Integral power steering system power cylinder, control valve and steering machine are a unit contained together. This type of power steering system is most common in modern cars.
(2) Pull rod type power steering system power cylinder near the middle position of the steering transmission mechanism. There are two types of pull-rod power steering systems: split and combined.
1) Separated type: power cylinder, control valve and steering machine are completely separated units.

2) combined type: control valve and power cylinder as a unit. The steering machine is a separate unit. (Combined power steering systems are commonly used on heavy trucks and buses)
