Pumping operation of JRP series Roots effected through two
‘8’shaped rotors in pumping chamber rotating opposite directions. With
drive ratio of 1:1,two rotors constantly seal against themselves without
touting each other and the chamer. The gaps between the movabls parts
are narrow enough to seal against the exhaust side and intake side in
visous flow and molecular flow,so that to chieve the purpose of pumping
the gas in the chamer.
When the rotors locate at 1 and 2 in
the chamber,the volume of air inlet will increase. When the rotors
locate at 3 in the chamber,part of air volume will be blocked out from
the air inlet. When the rotors locate at 4,this volume will open to
vent.When the rotors further,air will discharge through the air outlet.
Rotors will rotors more than two coures once every rotates.
The pressure difference between the inlet side and outlet side of roots
pump are limited. JRP series roots pump adopts a bypass valve.When the
value of pressure difference reaches to a certain figure,the bypass
valve opens automatically.Some air volume from the outlet side flows to
the reverse direction of inlet side through the bypass valve and reverse
passage,which reduce the operational load of roots pump and front-stage
pump greatly in the condition of high pressure difference.Meanwhile,due
to the function of unloading when bypass valve opens,it makes sure JRP
series vacuum pump and front-stage pump start at same time to aviod the
overload for both of them.
The roots pump has to be worked
as pump unit together with front-stage pump（such as rotating vane
pump,slide valve pump and liquid ring pump）.If it is required to reach
to higher vacuum degree,two sets of roots pumps can be connected to work
as a three stage roots pump unit.
Good Characteristic ：
There
is zero friction between rotors,also between rotor and pump chamber,so
there is no need of lubricating oil.Consequently,our pump can aviod the
oil pollution on vcuum system.
Compact structure,and easy to install horizontally or vertically
Good dynamic balance,stable running,small vibration and low noise
Can pump off the non-condensable gas
Quick started and can achieve the utmost pressure in a short time
Small power and low operation maintence costs
The
bypass value on roots pump can enjoy the automatic overload protection
effect,so that the operation will be safe and reliable
Application Range ：
vacuum drying and impregnation
vacuum degass
vacuum predischarging
gas exhausting
for
the processes in vacuum distillation, vacuum concentration and vacuum
drying in chemical industry,medicine,food and beverage,light industry
and textile industry
