Liquid Ring Vacuum Pump

Liquid Ring Vacuum Pump

CZPT CZPT &lparXihu (West Lake) Dis.&rpar Co&period&comma Ltd is the specialist vacuum pump supplier&time period
2BV sequence water ring vacuum pumps are suited for pumping the gases and steam&interval Its suction strain can achieve 33mbar &lparABS&rpar &lpari&period of time e&period ninety seven &percnt vacuum degree&rpar&interval If the transformer oil is utilized as the working liquid&comma these pumps are called oil ring vacuum pump and the suction strain can get to 6&period7mbar &lparABS&rpar &lpari&time period e&period 99 &percnt vacuum diploma&rpar&interval So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely&time period When the liquid ring vacuum pumps work below the situation in close proximity to the constrained vacuum for a long time&comma it is required to pair with the cavitation safety pipe in purchase to get rid of the screaming and protect the pump&period

When the compressor is doing work&comma the highest strain is &period26MPa &lparABS&rpar&period of time And the larger of discharge stress&comma the greater of the electricity of the compressors&time period So it is necessary that the info of the discharge strain is offered to pick the suitable motor&time period
2BV2-Ex&comma 2BV6 collection water ring vacuum pumps and compressors are largely used for pumping the explosive gases or operate in the flammable and explosive environment&time period The complex parameter of every single sort is the very same as the corresponding variety of the 2BV2 or 2BV5 collection products&period
2BV series stainless metal pumps can be employed underneath the conditions with greater demands for the corrosive-proof or the lustration&period

According to the functioning situation&comma the content of all the elements exactly where the liquid flows &lpari&interval e&period of time Pump casing&comma pump cover&comma port plate&comma and impeller&rparare made of various stainless metal as bellow&colon
SUS304 &lpar0Cr18Ni9&rpar&comma SUS316 &lpar0Cr17Ni12Mo2&rpar&comma SUS316L &lpar00Cr17Ni14Mo2&rpar
The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are utilized the John CZPT goods and the seals materials is optional for FPM or PTFE&interval

2BV series goods have the qualities as bellow
· The shut-coupled layout is handy to put in and can save area&time period
· The CZPT seals are all utilized the John CZPT mechanical seals&period
· 2BV collection goods have the cavitation defense port&period of time When they perform under the issue near the limited vacuum&comma the cavitation safeguard port opens &lparor connects with the separator&rparto get rid of the screaming to protect the pump&period

· Aluminum bronze impeller is of large depth and wearing effectively&period The erosive-evidence ability of the pump can be improved by using it&period of time If the areas exactly where the liquid flows are created of the stainless steel&comma the pumps can be utilized below the a lot more arduous issue&time period
· The exclusive layout of the discharge port can safeguard the pump from the over-stress to ensure the ideal productive functionality in the working variety of the pump&interval
· The motors are all adopted Y2 series products&time period The safety class is IP54 or IP55 &lparnormal is IP44&rpar and the insulation grade is F&time period
· The bearings are all utilized the imported products with brand name name of NTN or NSK&period
