Introductive
This standard is pair of JB/T 6533, 92 " type of blade type vavuum pump and basic parameter " , ZB J78 004, 87 " 2X blade style is true
Condition of empty pump technology " , JB/T 5281, 91 " condition of technology of vavuum pump of type of straight couplet blade " , JB/T 6532, 92 " vacuum of type of straight couplet blade
Pump type and basic parameter " edit.
The ultimate total pressure, requirement that starts temperature than power, lowest raised when this standard edits; Increased not fuel injection, do not leak to check oilily square
Law; Wait to project of test of town of noise index, gas, sampling method, type undertook modification.
This standard replaces JB/T 6533 at the same time since the day of autogenous effect, 92, ZB J78 004, 87, JB/T 5281, 91, JB/T 6532, 92.
The appendix A of this standard is standard appendix.
This standard standardizes technical committee to put forward by countrywide vacuum technique and put in a mouth 's charge.
This standard drafts an unit: Vavuum pump factory of institute of technique of vacuum of Shenyang of machinist trade department, Shanghai, Beijing instrument factory.
This standard basically drafts a person: Li Yuying, He Bi unripe, Zhao Yang.
