摘要(Abstract):

流体反输型密封装置工作时始终被清水冲洗,被密封液体与装置脱离接触,阻止了矿物质、添加剂在装置上的析出以及固体颗粒的磨损,可以提高污水泵的密封性能,延长其使用寿命。而且密封液也随污水回注油层,无附加能量损失。
A new type of sealing device is designed and washed all along by clean water. It can prevent sewage from contacting with the spiral, therefore can hold back the deposition of the minerals and additives one the device and avoid the wear of the solids. The service life and the sealing performances of the device was improved. The sealing liquid is pumped into oil reservoir along with the sewage, so no addition energy was wasted.
