离心式注水泵是采油厂的主要注水设备,由于它需要的功率大,是采油厂主要耗电项目。胜采厂共有型号不同的注水泵40台,每天开泵台数约15台,耗电量约为720000kw/h,如果能够将每台泵的泵效提高1%,就能降低电量损失5%,每天15台泵可节约20974kw/h,按每度电0.5元计算,每天可节约电费10487元,每年可节约电费3775320元。因此,研究离心泵的三大损失,对提高离心式注水泵效率具有重要的意义。 Centrifugal water injection pump is the main water injection plant equipment, because of its power needs, it is the main power plant project. There are 40 different injection pumps in Shengseng Plant, with about 15 pumps per day. The power consumption is about 720,000kw / h. If the pump efficiency of each pump can be increased by 1%, the power loss can be reduced by 5% 15 pumps can save 20974kw / h, calculated at 0.5 yuan per kWh per day to save electricity 10487 yuan, 3775,320 yuan per year to save electricity. Therefore, the study of three centrifugal pump losses, to improve the efficiency of centrifugal water injection pump is of great significance.
