Hydraulic oil is the direct medium of hydraulic system work. All the power and operation control of hydraulic system are transmitted by hydraulic oil. The main parts that cause “deterioration” of hydraulic oil are hydraulic oil tank, hydraulic oil filter and hydraulic parts. Impurities etc. produced.
1. The hydraulic oil tank is a place to provide hydraulic oil, heat dissipation and cooling, deposit impurities and discharge air from the hydraulic system.
First of all, the insufficient supply of hydraulic oil will cause the hydraulic oil pump to be emptied, which will lead to insufficient oil supply of the hydraulic oil pump, which directly leads to the wear of the hydraulic oil pump, which will soon cause the hydraulic oil pump to be seriously damaged to scrap.
Secondly, air suction will also mix air into the hydraulic oil, which will increase the compression elasticity of the hydraulic oil and reduce the volumetric efficiency of the hydraulic oil pump and other working devices. At the same time, the air in the hydraulic oil is compressed to form air during the operation of the oil pump and the working device. The cavity will damage the sealing surface, and will also cause the oil pump and working equipment to wear out quickly.
The prevention method is to frequently check the hydraulic oil in the hydraulic oil tank to ensure that the amount of hydraulic oil is within the normal range.
2. The hydraulic oil filter is used over time.
The impurities in the hydraulic oil are adsorbed on the surface of the filter element and the filter element is blocked, which will also cause the oil pump to absorb insufficient oil and cause air suction. Regular replacement of the hydraulic oil filter is the most effective preventive method.
Tianjin Goldenhugeline hydraulic filter has always been quality-oriented and can meet the filtering accuracy requirements of various conditions. It provides clean hydraulic oil for the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving parts, and provides lubrication. , Cooling and cleaning, thereby extending the life of these parts.
Third, the hydraulic oil will not be replaced if it has been used for too long
The impurities (iron filings, copper filings, dust, etc.) in the hydraulic oil will accumulate more and more, and at the same time the fine particle size will become smaller and smaller, which is invisible to the naked eye and can easily pass through the hydraulic oil filter. At the same time, if the hydraulic oil is used for too long, the various characteristics of the hydraulic oil, such as lubrication performance, viscosity characteristics, anti-wear performance, rigidity characteristics, etc., will be greatly reduced. The impurities in the hydraulic oil are brought to various working devices and control components through the working cycle. It directly leads to the rapid wear of the hydraulic components of the entire hydraulic system.
The preventive method is to change the hydraulic oil regularly, or take samples for inspection regularly, and replace it in time if it is found to exceed the standard.
