An improved method of analyzing a water pump lubricant filter
Water injection pumps are essential equipment for oil recovery. The normal operation of these pumps directly affects the completion of production tasks and is closely related to energy-saving efforts at the joint station. At the first oil production plant's joint station, there are a total of 6 water injection units, including 3 D300-150 × 10A large pumps rated at 2000kW and 3 DFl20-180 × 12 high-pressure pumps rated at 1200kW. Over the years, lubrication system failures have frequently disrupted the operation of these pumps, leading to an average of more than 15 annual overhauls. Each overhaul takes over 3 days, and each pump requires more than 45 days for maintenance annually. This results in significant consumption of manpower and resources.
After careful analysis of the design and working principle of the lubricating oil system, it was identified that the main issue stemmed from the unreasonable structure of the lubricating oil filter. Following a redesign and implementation of improvements, the system was put into operation with excellent results. The risk of accidents was completely eliminated, and stable production was ensured.
**1. Existing Problems**
Through observation and analysis, several issues were identified with the original lubricating oil filter:
a. Disassembly and cleaning are inconvenient. The filter gland is directly connected to the filter outlet line, requiring the entire filter to be removed along with the pipeline for cleaning, making routine maintenance difficult.
b. The system is prone to leaks due to poor sealing.
c. The gland installation cannot be properly aligned. The directional nature of the filter gland pipelines causes misalignment during compression and connection.
d. There is insufficient lubricant flow. Because the oil enters from the bottom of the filter, the space between the filter core and the base is too small, resulting in limited oil flow that fails to meet the lubrication requirements of the water pump.
**2. Improvement Measures**
Based on the above analysis, the primary issue was the structural defect caused by the direct connection between the filter gland and the pipeline. To address this, the following solutions were implemented:
a. The filter outlet was redesigned to be located on the top of the filter, separate from the filter gland. This allows for cleaning without removing the entire lubrication line, solving the problem of improper gland tightening and reducing oil leakage.
b. The filter inlet was moved from the bottom to the lower part of the filter, increasing the oil intake space and ensuring sufficient lubricant supply to meet the needs of the water pump.
c. A pressure ring was added to the upper part of the filter core, keeping it fixed during operation and preventing any impact on the filtration performance.
**3. Results After Implementation**
The technological improvement required minimal investment and involved simple modifications without major changes to the existing lubrication system. After the transformation, the filter demonstrated excellent sealing performance and ease of maintenance. Since its implementation, frequent overhauls of the lubrication pumps have been completely avoided, significantly reducing pump downtime and ensuring the smooth completion of water injection tasks. This has not only improved operational efficiency but also contributed to cost savings and better resource management.
