CZPT Co., Ltd is the skilled vacuum pump provider.
2BV sequence h2o ring vacuum pumps are suited for pumping the gases and steam. Its suction pressure can achieve 33mbar (Ab muscles) (i. e. ninety seven % vacuum degree). If the transformer oil is used as the functioning liquid, these pumps are known as oil ring vacuum pump and the suction stress can reach 6.7mbar (Ab muscles) (i. e. ninety nine % vacuum diploma). So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps entirely. When the liquid ring vacuum pumps perform below the problem close to the minimal vacuum for a extended time, it is required to pair with the cavitation defense pipe in buy to get rid of the screaming and safeguard the pump.
When the compressor is functioning, the highest force is .26MPa (Abdominal muscles). And the higher of discharge force, the greater of the power of the compressors. So it is required that the data of the discharge pressure is presented to select the correct motor.
2BV2-Ex, 2BV6 collection water ring vacuum pumps and compressors are mainly utilized for pumping the explosive gases or function in the flammable and explosive atmosphere. The technological parameter of each and every variety is the very same as the corresponding kind of the 2BV2 or 2BV5 series merchandise.
2BV sequence stainless steel pumps can be utilized beneath the circumstances with higher requirements for the corrosive-evidence or the lustration.
In accordance to the operating scenario, the content of all the elements exactly where the liquid flows (i. e. Pump casing, pump include, port plate, and impeller)are created of different stainless metal as bellow:
SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)
The content of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John CZPT goods and the seals material is optional for FPM or PTFE.
2BV sequence merchandise possess the qualities as bellow
· The near-coupled design is handy to put in and can preserve area.
· The CZPT seals are all utilised the John CZPT mechanical seals.
· 2BV sequence goods have the cavitation protection port. When they operate under the situation near the minimal vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to safeguard the pump.
· Aluminum bronze impeller is of high depth and donning nicely. The erosive-evidence ability of the pump can be improved by employing it. If the areas exactly where the liquid flows are created of the stainless steel, the pumps can be utilised underneath the more rigorous problem.
· The unique style of the discharge port can protect the pump from the more than-pressure to ensure the very best effective functionality in the functioning selection of the pump.
· The motors are all adopted Y2 series merchandise. The safety class is IP54 or IP55 (typical is IP44) and the insulation quality is F.
· The bearings are all employed the imported merchandise with model title of NTN or NSK.
