Introduction
Overview :YJ series two-stage Roots vacuum pumps , the company is YJ series single-stage Roots pump , based on carefully researched successfully developed a new generation of replacement products, the indicators have reached the level of similar foreign products .
Currently in China , Roots vacuum unit to obtain a high vacuum is the main way Multiple Roots pumps coupled in series before the pump , multiple pumps in series Roots Although relatively flexible, but complex piping connections , equipment, complex composition , increasing the leakage point and maintenance costs , along with the extensive application of Roots vacuum pumps and related industrial technology requirements increase, there is a growing need for an easy to use and maintain , reliable operation of the new Roots vacuum pump to improve their production efficiency and reduce production costs.
Two dual -stage Roots vacuum pump series single-stage Roots vacuum pumps are integrated , the use of equipment , dual-stage Roots vacuum successful development , optimization of the structure and composition of the unit , reducing the cost.
The main structure and principle:
1 , the rotor : The rotor is the core component of Roots vacuum pump , design and processing requirements, made by precision CNC machining , each of four , mounted on a pair of parallel shafts , each shaft assembly of different sizes, two rotors ;
2 Housing: according to certain pumping speed ratio of the two chambers housing the Chinese and sizes , namely the level of the vacuum chamber ;
3 , the synchronization gear: the core part of Roots vacuum pump , which is used to ensure the synchronization of the two rotors rotate, and to maintain the clearance between the rotor , gear surface is high-frequency quenching , and then formed by a special precision grinding ;
4 ,
Was pumping gas from the suction port first enter the high vacuum chamber , and then pass through the wall of the gas into a low vacuum chamber , and finally through the discharge port to the next pump.
Main features:
1 , the exhaust chamber oil water, no secondary pollution ;
2 , with two single-stage pumps in series compared to compact, small footprint ;
3 , fewer parts , ease of maintenance and repair, reducing the cost ;
4 , the level of the internal connection between the vacuum chamber , reducing the two pump connecting pipe between the amount of leakage , improve unit performance indicators ;
5 , the internal structure are optimized to improve the efficiency of the pump , reducing the power consumption;
6 , the entire unit's control system more simple and convenient ;
7 , reducing the unit auxiliary pipe fittings, more conducive to the production and maintenance of the unit ;
