2BV2 Pressure Gas Steam Fluid Liquid Water Ring Vacuum Pump

Introduction of 2BV2 High Pressure Gas Steam Fluid Liquid Water Ring Vacuum Pump

2BV2 High Pressure Gas Steam Fluid Liquid 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.

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.
 
Comparing with the SK, 2SK, SZ water ring vacuum pumps, the 2BV series products possess the characteristics as bellow:
The close-coupled design is convenient to install and can save space.
The standard seals are all used the John Crane mechanical seals.
2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump.
Aluminium bronze impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel,the pumps can be used under the more rigorous condition.
The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the pump.
The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.
The bearings are all used the imported products with brand name of NTN or NSK.

A semi-trailer is a commercial vehicle equipped with a special device for traction semitrailer.

The front driver is called the tractor, the rear no traction drive car is called the trailer, the trailer is dragged by the tractor.
There are two kinds of connection mode of the tractor and the trailer: the first one is the front half of a trailer traction saddle in the tractor rear section on the top of the back of the car bridge under traction Trailer part weight, which is half hanging; second is the front end of the tractor trailer even the rear of the towing vehicle only provide forward force, dragging the trailer go, but does not bear the weight down trailer, this is the whole hanging.

Semi Trailer

According to their use, roughly divided into flat semi-trailer, dump semi-trailer, low flat semitrailer, box type semi-trailer semi-trailer truck, warehouse bar, transport semi-trailer, LPG transport semi-trailer, chemical liquid transport semi-trailer tank, transport semi-trailer, powder material transportation semi-trailer, Aluminum Alloy semi trailer,  concrete mixer semi trailer.

Tractor

According to the driving form,roughly divided into 4x2,4x4,6x2,6x4,6x6,according to the type of fuel, roughly divided into diesel tractor,LNG tractor,CNG tractor.

Semi Trailer
