Structure and Features
With roots pump for the chief pumps, water ring vacuum with air ejectors system as backing pump establish. It has many virtues as follow compared with the same number Roots pump systems with water ring vacuum pumps
- High vacuum, high pumping speed in lower pressure
- It also can save energy because series PQ air ejector needn’t power when running.
- Different pressure of the roots pump fall, reduce excessive high temperature of the roots pumps and operate reliably.
Can be combined as follow according as different useful request
1) A roots pump systems with air ejector and water ring vacuum pump
2) Two roots pump systems with air ejector and water ring vacuum pump
Use
The vacuum system is suitable for high vacuum distilling, vacuum vaporizing and vacuum dehydrating-crystal of chemical and medicine industry, vacuum drying and vacuum soaking of electric utility and light textile industry, freeze-dryer of food industry etc. |
