The effect of installing the oil return filter on the breaker

The function of the oil filter element is to filter the sludge in the automobile engine and the residue formed by the deterioration of the engine oil itself, to avoid the deterioration of the engine oil, and to greatly reduce the damage of each component during the operation. It is proposed to improve an oil return filter element to prevent the unfiltered residue from entering the hydraulic transmission system and damage the hydraulic pump during application. So what is the effect of installing the oil return filter element?

For the breaker with the hydraulic transmission system as the key energy structure, the hydraulic transmission system is spread throughout the entire excavator, which covers the hydraulic oil tank, the main valve, the pressure regulating valve, the pipelines and the hydraulic cylinders, motors and other components for each operation. , These hydraulic components are all processed by precision machining, and they have higher requirements for the maintenance of the hydraulic transmission system.

When the hydraulic oil enters the hydraulic transmission system, cleaning is the main problem. The filtering effect of the fake hydraulic oil filter element is poor, and it cannot reasonably prevent foreign objects and other residues from entering the system. If the hydraulic transmission system enters the fine magazine particles, they will Scratch the pump, jam the valve, block the oil hole, and cause equipment problems.

The hydraulic oil filter is used in the hydraulic transmission system to filter out the solid particles and colloidal components in the working components, which can reasonably control the influence level of the working components, maintain the reliable operation of the equipment, and increase the service life of the equipment. Bad is very important.

On the basis of the original hydraulic filter device of the breaker, an oil return filter element is added. The setting of the oil return filter element needs to fully consider more elements. One of the main elements is hydraulic impact, especially if there is a hydraulic pressure upstream. In the case of the cylinder and proportional valve, the reversing of the hydraulic cylinder and the sudden power failure of the proportional valve under high pressure will cause a very large and rapid total flow impact, which will cause very large damage to the filter element of the oil filter. When using the oil filter of the oil return line, there must be sufficient understanding and the structure type should be strengthened.
