Description

Technical Field

[0001] This utility model relates to the field of well workover machine technology, and in particular to a well workover machine oil suction filter element with a dirt collection function. Background Technology

[0002] Well workover rigs and special equipment often operate in the field under harsh conditions. If the hydraulic oil is too dirty or the hydraulic oil tank is not thoroughly cleaned during oil changes, the hydraulic system will frequently malfunction. For example, the hydraulic system control valves may become clogged, resulting in reduced displacement pressure, increased fuel consumption, or excessive wear on the gear pump. This can prevent the equipment from continuing to work, affecting its performance, construction progress and output, increasing maintenance costs and repair costs, and increasing the consumption of oil and materials, resulting in significant waste. Therefore, it is necessary to use an oil suction filter to filter the hydraulic oil.

[0003] In existing technology: During the operation, when raising or lowering the tubing string, the hydraulic tongs are changed according to the required tightness of the tubing string. Each time the quick-connect couplings of the hydraulic lines are disassembled and installed, hydraulic oil is lost and consumed. In addition, oil and mud from gloves may be accidentally introduced into the hydraulic system, causing premature wear of hydraulic system components and hydraulic pumps. Due to hydraulic system failures, at least one gear pump needs to be replaced every year, costing more than 30,000 yuan. In addition, the material costs and maintenance costs caused by hydraulic system failures and hydraulic oil replenishment result in direct economic losses of up to tens of thousands of yuan. In response to the above problems, the literature with application number: 201220565932.7 discloses a hydraulic oil filtration device for workover rigs, which includes a hydraulic oil tank, an oil pump and a filter tank. The inlet line of the oil pump extends to the bottom of the hydraulic oil tank, and the outlet of the oil pump is connected to the inlet line of the filter tank. A cylindrical filter element is installed in the filter tank, and the outlet line of the filter tank is connected to a second oil pump. The outlet line of the second oil pump extends into the hydraulic oil tank. The hydraulic oil filtered by this filtration device has significantly increased anti-wear properties and hydraulic system pressure, greatly reducing maintenance costs and improving equipment utilization and availability.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: Although it is possible to filter impurities in hydraulic oil, the lack of a dirt collection structure means that some filtered impurities will adhere to the filter element, which not only affects the filtration of hydraulic oil but also makes it inconvenient to collect and clean the filtered impurities, leaving room for improvement.

[0005] Therefore, this application proposes a well workover rig suction filter element with a sludge collection function to solve the above problems. Utility Model Content
