Oil injection screw vacuum pump is a kind of dry pump specially for industrial application. It is a new design, which is specially used to solve the vacuum problems in industrial application, such as dust, tar, etc. Oil injection screw vacuum pump adopts variable pitch rotor with internal compression process and no bearing and seal in the pump cavity, which greatly reduces the failure rate. There is no internal valve in the pump cavity, so it has strong resistance to dust and tar. The screw of this pump adopts internal hollow cooling, which can reduce the rotor temperature and thermal deformation, and increase the screw life. The following gives you a detailed explanation of the characteristics and advantages of oil injection screw vacuum pump products.
Oil injection screw vacuum pump features:
High efficiency:
Flexible screw host, patented “throttling control” design, through the slide valve real-time adjustment of the exhaust port position to ensure the best position, the main motor energy consumption is reduced by about 20% compared with the conventional screw vacuum pump under the same air displacement; the direct drive saves energy by 5% than the belt drive and 3% than the gearbox drive; the whole machine is more energy-saving and environmentally friendly.
Longevity:
The main engine adopts cylindrical and tapered roller bearing triple design, bearing life ≥ 100000 hours; the main engine is guaranteed for five years, and the motor and heat exchanger are guaranteed for two years.
Low noise:
Direct drive, no gear noise; shell and main engine intake noise elimination, to achieve amazing low noise operation.
High vacuum capacity:
It can reach the maximum vacuum degree of more than 29.9inhg, which is suitable for continuous and stable vacuum applications or production requirements.
High reliability:
Patent intake valve, large diameter, low pressure drop, through 5 million cycle life test, sensitive response, reliable operation, maintain system vacuum under harsh conditions, achieve high reliability.
Integration technology:
Intelligent PLC, real-time monitoring; cloud management, remote support; fault analysis and recovery, high temperature protection and other protection functions; multi machine joint control, centralized management, active energy-saving settings, reduce operating costs.
High efficiency separation system:
High tech seals and lubricants are used to seal the main engine rotor, lubricate the bearings, and provide cooling and heat dissipation; the separation system uses nano materials (non lipophilic and non hydrophilic) plus multi-stage separation system to efficiently separate and purify the exhaust mixture containing lubricating oil, reduce the loss of lubricating fluid and improve the separation efficiency.
Forced lubrication:
Positive displacement forced lubricating oil pump ensures the full lubrication of vacuum pump at different vacuum degrees.
Non throttling intake design:
The special intake design and throttling control design of flexible screw host make it run at full load from atmospheric pressure to maximum vacuum. That is to say, when there is a sudden load demand, the system vacuum can still be well maintained. Other models use intake throttling design when vacuumizing the system, which reduces the air intake load. When the system vacuum suddenly decreases, it has to protect itself to prevent motor overload.
