oil free compressor pump
1. The impeller type line is advanced and the efficiency is high
2. The use of frequency conversion adjustment, the maximum to meet the needs of the user. At the same time, theanti surge system is equipped to avoid the vacuum pump entering the surge area, and the better protection equipmentwill not be damaged.
3.The vacuum pump is compact in structure and small in volume.Adopting the assembled integral structure, the vacuum pump body is assembled on the shell of the gear increasingbox, and the lubricating oil system is arranged in the chassis of the unit tightly. The motor and gearbox are installed onthe common base, and the base is also used as the oil tank.
Industrial pumps is a new product developed by Zhangqiu wind blower Limited by Share Ltd and Xi'anJiao Tong University in Shandong province. The aerodynamic performance and structure design of this series of productshas reached the advanced level of similar products at home and abroad. lt can be widely applied to vacuum systemssuch as paper machines, vacuum dehydration, life paper folding machines, vacuum systems, vacuum dedusting andvacuum packaging.
Impeller：According to the three dimension flow theory to the design ofhigh efficiency, the precision machining after strict dynamic balancecorrection, and through overspeed test 1.15 times the rated speed, ensurethe impeller strength. in order to meet the needs of different workingconditions, the impeller can be used for many kinds of materials such asforging aluminum, stainless steel and titanium alloy.
High-speed Rotor：The high speed rotor consists of the impeller, the high speed gear andthe high speed shaft. The impeller is connected to the high speed shaftby the pull rod, and the torque is passed on the end face pin. In order toensure the smooth and reliable operation of the vacuum pump, the overallbalance precision of the high speed rotor is G1.
Gear：The speed increasing gear pair for the involute tooth shape, the sizegear surface is all grind and nitriding hardening treatment, guarantees thevacuum pump to run at high speed steadily, the vibration and the noise aresmall, the life can reach 20 years.
Bearing：High speed bearings with tilting pad sliding bearing is composed of aplurality of pivot deflection activities can be composed of its anti vibrationpad, excellent performance, and can be automatically adjusted accordingto the change of load and speed changes.
