Double Stages High Vacuum Pump System Combination For Electrical
Equipment Air Dryer
Application:
In case single vacuum pump is not suited for a certain process due
to pumping speed or ultimate vacuum. DYK Series vacuum pumps unit
consist of roots pump as booster and rotary vane pump as backing
pump, the exhaust from the roots pump is connected to the suction
side of the backing pump thereby giving advantage of high pumping
speed at higher vacuum. The pumps unit also equips air cooling
system,cooling water system, vacuum valves,ventilation valves,
compensator, vacuum meter etc, and highly efficient, reliable and
consume less power. It also can be designed and mounted on base
frames ready for use, or trailer are offered to suit user's
requirements. DYK unit is wildly applied in vacuum metallurgy,
vacuum drying, welding, chemical, laboratory, power
station,electric power industry of transformer, wire and cable,
condenser vacuum impregnation, vacuum drying process. It’s the
ideal vacuum equipment for the industry of vacuum coating, vacuum
smelting, vacuum heat treatment, vacuum oil filter, freeze drying,
aviation simulation test and other industrial vacuuming, especially
for vacuum transformers and other electrical equipment operation.
Feature:
▲ The machine adopts special Roots pump and vacuum pump, so the
vacuum pumping speed and pressure are obviously better than any
other devices.
▲ Roots pump automatically runs by the start of backing pump with
electrical-contact vacuum meter.
▲ The powerful rotary vane backing pumps generate the necessary
backing pressure so that the diffusion pump can always attain its
full pumping speed and an ultimate vacuum
▲ The pumping unit has vacuum valve at the inlet and a rough vacuum
line (bypass). This makes it particularly efficient for rapid
evacuation cycles.
▲ The high vacuum pump unit offer outstanding energy savings, high
efficient, reliable and low power consumption
▲ The forward pump adopts the original world's leading vacuum pump
imported from Europe, and customers can choose the imported Roots
pump or homemade ones according to their purchasing power.The pump
can attain high working vacuity at a vey fast pumping speed.
▲ Equipped with Pipeline filter so as to keep large impurities out
of the system, not damaging the vacuum pump.
▲ Working vacuum range and maximum vacuum degree are superior to
other products.
▲ It is installed with special vacuum gauge for accurate
indication.
▲ It adopts automatic vacuum relay for automatic control.
▲ Stable and reliable operation, low noise, and easy to move.
