Liquid Ring Vacuum Pump

CZPT CZPT &lparXihu (West Lake) Dis.&rpar Co&interval&comma Ltd is the expert vacuum pump provider&period
2BV sequence h2o ring vacuum pumps are suitable for pumping the gases and steam&period of time Its suction force can get to 33mbar &lparABS&rpar &lpari&period e&period 97 &percnt vacuum diploma&rpar&time period If the transformer oil is employed as the working liquid&comma these pumps are named oil ring vacuum pump and the suction pressure can achieve 6&period7mbar &lparABS&rpar &lpari&period e&interval ninety nine &percnt vacuum degree&rpar&interval So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps completely&interval When the liquid ring vacuum pumps function beneath the condition in close proximity to the restricted vacuum for a lengthy time&comma it is essential to pair with the cavitation defense pipe in purchase to get rid of the screaming and safeguard the pump&time period

When the compressor is working&comma the greatest stress is &period26MPa &lparABS&rpar&time period And the greater of discharge stress&comma the larger of the energy of the compressors&time period So it is needed that the knowledge of the discharge pressure is provided to choose the suitable motor&time period
2BV2-Ex&comma 2BV6 sequence water ring vacuum pumps and compressors are largely used for pumping the explosive gases or perform in the flammable and explosive environment&interval The complex parameter of each and every sort is the very same as the corresponding sort of the 2BV2 or 2BV5 collection goods&time period
2BV sequence stainless steel pumps can be utilised under the circumstances with larger demands for the corrosive-evidence or the lustration&interval

In accordance to the working circumstance&comma the material of all the elements where the liquid flows &lpari&period e&period Pump casing&comma pump include&comma port plate&comma and impeller&rparare made of different stainless steel 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 utilised the John CZPT goods and the seals substance is optional for FPM or PTFE&period

2BV series goods have the characteristics as bellow
· The shut-coupled design and style is hassle-free to put in and can save space&interval
· The CZPT seals are all employed the John CZPT mechanical seals&period
· 2BV series goods have the cavitation security port&period When they operate beneath the issue near the constrained vacuum&comma the cavitation protect port opens &lparor connects with the separator&rparto get rid of the screaming to shield the pump&period

· Aluminum bronze impeller is of substantial intensity and donning nicely&time period The erosive-proof ability of the pump can be enhanced by employing it&time period If the components exactly where the liquid flows are produced of the stainless steel&comma the pumps can be employed under the more demanding problem&period of time
· The exclusive style of the discharge port can safeguard the pump from the above-force to make sure the very best effective efficiency in the operating variety of the pump&period of time
· The motors are all adopted Y2 collection items&time period The security course is IP54 or IP55 &lparnormal is IP44&rpar and the insulation grade is F&interval
· The bearings are all utilized the imported items with model name of NTN or NSK&interval
