Screw vacuum pump GVS900-3900
-
The operating principles of the screw vacuum pump are described as follows: a pair of meshing screw rotors rotate in opposite directions, so that the screw groove space is changed from small to large, the air intake, compression and exhaust are caused, and then the gas in the target space is pumped away and exhausted. Lubricating oil plays a role in lubrication, cooling and cleaning, and it also plays a very important role in sealing the gap between rotors and between rotor and case, thus improving the volumetric efficiency. With air intake control, cooling system, variable frequency control, automatic logic control, etc., automatic system operation can be realized.
Screw vacuum pump is composed of twin-screw main machine and other components;
It is researched, developed and designed independently; Advanced design concept is adopted to provide products with better cost performance;
In the design, technology, material, manufacturing and other links, cost is controlled in a scientific and reasonable way, ensuring leading performance and controllable cost;
Efficient and reliable products with reasonable cost performance can hit the middle and high-end market dominated by foreign capital;
15~55 kW, covering the mainstream demand range.

Screw vacuum pump
It is designed for vacuum applications. Optimally developed twin-screw main machine is efficient and reliable; The motor is driven directly without transmission loss; The transmission efficiency is highest and fault points are reduced;
Permanent magnet synchronous variable frequency motor can ensure high efficiency under full load or partial load conditions. The power factor is high, reducing the burden of power grid;
Air intake filter designed for vacuum applications can effectively protect the rotor and improve the efficiency of the whole machine with ultra-low pressure drop; The oil-gas separator with advanced design concept can ensure ultra-low oil content in exhaust air (less than 3 ppm), protect the environment and reduce the consumption of lubricating oil. Low oil separation pressure drop reduces exhaust back pressure and power consumption, and improves the efficiency of the whole machine;
Air ballast design (option) (wet application version) can be used for the application of water vapor in intake air flow, broadening the application surface
Vacuum intake valve can ensure normal operation of equipment. Meanwhile, ultra-low pressure drop improves the overall efficiency of the vacuum pump;
The oil circuit system (including temperature control valve, oil filter, cooler and pipeline) with overall control of pressure drop can supply oil normally without extra lubricating oil pump, ensuring the operation and cooling of vacuum pump, and reducing fault points;
Air-cooled type, centrifugal fan cooling system, high efficiency and silence (GVS minimal machine is of axial flow cooling);
Variable frequency control is provided. According to the set degree of vacuum and customer load, the speed will be automatically adjusted, so as to meet the customer demand and stabilize the degree of vacuum;
6" color touch screen PLC intelligent control is provided with intuitive and simple operations. Fault diagnosis, alarm record, parameter setting, maintenance, etc. are provided;
The Internet of Things is supported, so the operation of vacuum pump can be remotely monitored through PC, Pad, mobile phone and other devices, and alarm information can be received.
