Product DescriptionZJ Series Roots Vacuum Pump OverviewThe
series ZJ roots vacuum pump is with overflow valve.Roots vacuum
pump (referred to as roots pump for short) is a non-internal
compression type rotary positive displacement pump, which achieves
suction and exhaust by two 8-shape rotors rotating in the pump
shell. Its principle is similar with roots blower.As it works
within the low pressure range, the free paths of the gas molecules
are long, and the resistance is strong for gas to pass through
small gaps, thus, it is able to obtain a higher compression
ratio, and can be used as a booster vacuum pump; But it can
not directly exhaust the gas into the atmosphere alone, and it
shall be connected with a fore vacuum pump in series, and
exhaust the pumped gas into the atmosphere through the fore vacuum
pump.Features 1. There is a certain gas between the rotor
and pump chamber, and between rotors. They do not contact with each
other, and do not need oil lubrication.2. Rotor has a good
geometric symmetry, and can improve the rotary speed so as to
produce a compact large pumping rate pump. 3.Pump works
with small vibration and large capacity, and the capacity
utilization factor is around 0.5.4. In the pump chamber, there is
no compression as the mechanical vacuum pump does, so it does not
require an exhaust valve. For this reason, it can be used to pump
the condensable vapors.5. It starts fast, and can achieve the
ultimate vacuum in a short period. It has low power and low
maintenance cost for operation.6. Roots pump owns a high
pumping rate in a wide range of pressures (1000PA ~ 1PA).
It is able to quickly exhaust the gases which are suddenly released
of gas, and cover the shortage of low pumping rate of the diffusion
pump and oil sealed mechanical pump under the pressure of (1000PA
~ 1PA). As a result, it is most suitable used as
a booster pump.Applications ZJ series roots vacuum pump
is a kind of rotary positive displacement pump, which must be
used with a fore pump. It has a higher pumping rate in
a wider pressure range, and not sensitive to the pumped gases
which contain dust or water vapor. Therefore, it is widely used in
the metallurgy, chemical industry, food, electronic coating and
other industries.SpecificationsModel(L/S) PumpingSpeed≤(Pa)
