Description

Technical Field

[0001] The utility model belongs to the technical field of oil filter vehicles, and in particular relates to a high-efficiency oil filter vehicle. Background Art

[0002] According to statistics from the International Organization for Standardization (ISO), pollution is the main cause of 70%-85% of hydraulic system failures. Among the many types of pollution, solid particle pollution is the main pollution of hydraulic systems and oil. For the control of solid particle pollution, on the one hand, in the hydraulic system design stage, according to the sensitivity of the hydraulic system to pollutants, corresponding filters are set in the hydraulic circuit to intercept solid particles. On the other hand, in the later operation of the hydraulic system, the cleanliness of the hydraulic system needs to be tested regularly in order to timely understand the cleanliness of the hydraulic system oil and take necessary treatment measures.

[0003] The hydraulic system filters equipped in the above-mentioned design stage include high- and low-pressure pipeline filters, oil suction filters, oil return filters, etc. Considering the cost, lightweight equipment, installation space, etc., the filters are often determined by giving a specific starting pressure drop based on the system pressure and system flow during the selection stage. This is more obvious in engineering vehicles, but the solid particle pollutants are generated the most during the early debugging and running-in stage of the newly installed hydraulic system. The particles brought by each hydraulic component, the particles brought in during the assembly stage, and the particles generated by the initial running-in wear, etc., will increase the filtering pressure of the system configuration filter. Therefore, some engineering vehicles have the problem of on-board filter clogging during the warranty period or even during the debugging stage. Therefore, bypass filtration of the hydraulic system is particularly important;

[0004] Most of the existing bypass filtration is a single bypass filtration form. Low-pressure bypass filtration has an oil filter cart that is only used for oil tank filtration and refueling filtration. In addition, due to the pursuit of cost reduction and structural simplification, the use of related accessories on site, such as oil pipe storage, cable storage, and equipment cleaning, is inconvenient, making equipment management chaotic. High-pressure bypass filtration is rarely used, and it mainly requires a vehicle-mounted high-pressure filter. Regarding the detection of cleanliness, sampling detection is currently the main method. However, the pollution in the sampling process and the professional quality of the sampling personnel also directly affect the test results, and the test cycle is relatively long.

[0005] Therefore, those skilled in the art have proposed a high-efficiency oil filter trolley to solve the problems raised by the background technology.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content
