2BV collection drinking water ring vacuum pumps are ideal for pumping the gases and steam. Its suction pressure can attain 33mbar (ab muscles) (i.e. ninety seven % vacuum diploma). If the transformer oil is employed as the running liquid, these pumps are called oil ring vacuum pump and the suction strain can achieve six.7mbar (ab muscles) (i.e. 99 % vacuum diploma). So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work underneath the condition in close proximity to the limited vacuum for a lengthy time, it is essential to couple with the cavitation security pipe in order to get rid of the screaming and protect the pump.When the 2BV collection are utilised as compressor, it should shell out consideration to the discharge stress and pick ideal motor electrical power as the improve of the discharge pressure will enhance the 2BV pump electricity.
Structure and attributes:
The direct link of the motor and pump with the exact same shaft saves room and is practical to set up.
Adopting mechanical seal as CZPT products, which removes leakage and can make the upkeep hassle-free.
Stable doing work and the sound can lower to sixty two decibel.
Distinctive design of versatile discharge port will not trigger above compression which for that reason, helps make positive the greatest effectiveness of 2BV in the functionality scope.
All the 2BV collection have the connection port of the cavitation protection pipe. E.g. when the pump operate below minimal strain, opening the link port of the cavitation safety pipe or connecting with the separator can eliminate the cavitation audio beneath the situation that the suction result can be created confident at utmost and shield the pump.
All the roughs of all the types in the 2BV collection undertake specific casting( stainless metal and typical content).
All the factors are processed precisely by the CNC lathe, and the mechanical seal adopts imported johncrane or HangZhou Bergman to make certain the precision.
All adopt NTN or NSK imported bearing.
