New three-point recovery technology for innovation in oil mist lubrication systems for petrochemical pump sets
Thread Content
The power source for the oil mist recovery unit in the pump train is instrument air; after passing through two stages of filtration, clean air is discharged from the unit’s exhaust outlet. (And the oil mist recovery regulator in the device allows for adjusting the negative pressure levels of the oil mist emitted from the front and rear ends of the pump bearings as well as from the collection box, enabling effective negative pressure regulation at multiple leakage points.) Truly achieve oil mist recovery through three-stage recovery)
Shijiazhuang Refining & Chemical: Revitalizing Old Facilities 2019-03-22 Source: Sinopec News Network, Petrochemical News. The Party branch of the First Oil Refining Operations Department at Shijiazhuang Refining & Chemical adheres to lean management principles and uses party building to support its core tasks; it has been awarded the title of Advanced Grassroots Party Branch at Shijiazhuang Refining & Chemical on multiple occasions, and in 2018 it was recognized as an Advanced Grassroots Party Organization by the group company. With the implementation of the points system, innovation, excellence, and achievement have gradually become the conscious actions of Party members. To address the long-standing problem of minor leaks in some pumps, the Party members in the equipment team organized technical efforts to modify the mechanical seals; by employing new technologies, they improved the operating conditions of the equipment and completely resolved the issue of seal leakage in those pumps. To address the issue of oil mist leakage from the oil mist lubrication systems used in on-site pumps, six additional oil mist recovery systems were installed to ensure sealed discharge and recovery, effectively solving the problem and yielding significant environmental benefits. During the annual HSSE inspection, the tidy and organized site environment as well as the use of new technologies were frequently praised by the experts from the inspection team
This lubrication method is particularly good; the operator only needs to keep an eye on the main oil tank
