Analysis of the Mechanism of Wear of Pumping Pumps and Discussion on Solutions
Core Tips: Discussion on the analysis and solution of the wear mechanism of the pumping pump Bu Fanjian (The Shengli Oil Production Plant of Shengli Oil Field Company, SINOPEC, Dongying 257051, Shandong, China) The control measures of grinding performance, sand formation prevention and sand injection prevention as means, and Explained some specific methods and their applications to solve the problem of pumping
The analysis of the wear mechanism of the pump and the discussion on its solution Bu Renjian (The Shengli Oil Production Plant of Shengli Oilfield Company, SINOPEC, Dongying 257051, Shandong, China) The management measures of grinding performance, sand prevention in sand formation, and prevention of sand pumping as the means, and expounded some The specific methods and their applications provide technical support for solving the problem of wear of the pump.
With the late stage of the oilfield, especially after entering the extra-high water cut period, the pump efficiency problem of the oil pump becomes more and more important. A prominent problem in the production for a long time is that due to the destruction of the formation cementation, the crude oil contains sand scum, which leads to the wear of the inner wall of the pump plunger or pump cylinder, and the short-term loss of the pump, resulting in a rapid drop in fluid production. Short-term failure of Shengtuo Oilfield (
Naipu SP metal Vertical Slurry Pumps are vertical, centrifugal slurry pumps submerged in sump to work.They are designed for delivering abrasive,large particle and high density slurries.These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.Wet parts of type NP-SP pump are made of abrasion-resistant metal. All parts of type NP-SP(R) pump immersed in liquid are lined with rubber outer liner.They are suited to transport non-edge angle abrasive slurry.
Typical Applications---
Sump drainage washdown
Floor drainage
Mill sumps
Carbon transfer
Monitoring
Magnetite mixing
