How does an oil filter treat hydraulic oil?

The main reason for lubricating oil quality control is that unqualified lubricating oil quality directly affects the operation of mechanical equipment. The viscosity of the lubricating oil does not meet the requirements. When the machine movement is subjected to shock, vibration and variable loads (such as uneven movement, frequent stopping or starting, reciprocating motion, or intermittent motion, etc.), a large instantaneous pressure will be formed.

When moving under normal operating conditions, excessive resistance will be generated, or the oil film will be crushed. When the flash point or solidification point of the lubricating oil does not meet the requirements, the movable pair may burn or freeze when it is working normally or stops moving.

When the lubricating oil contains mechanical impurities, it will cause wear of the machine's movement, accounting for about 50% of all wear, and then cause the movement to fail. Severe hydraulic oil contamination will cause abnormal operation of the equipment, scabbing, burning, wear of equipment, etc., so the following methods can be selected to deal with hydraulic oil contamination: The hydraulic oil vacuum oil filter developed and planned by Chongqing Oil Filter can quickly remove harmful components such as moisture, impurities and volatiles (such as ammonia) in the oil, improve the quality of the oil, and restore its function.

Ensure the normal operation of the hydraulic system, power system and lubrication system. Therefore, using oil filters to filter lubricating oil is not only to meet the requirements for oil quality, but also an important measure to protect mechanical equipment and ensure equipment function.

Hydraulic oil should mainly monitor the appearance, viscosity change, color change, acid value change, moisture, impurities, pentane insolubles, corrosion and other items of oil during use. Regular inspection of these items can detect problems in advance and take corresponding measures to prevent failures. My country has announced the oil change targets for HL and HM oils, which are SH/T0476-92 and SH/T0599-94, respectively. In principle, the hydraulic oil in use should be replaced with new oil when it reaches a target.

The main properties that hydraulic oil should have: suitable viscosity and excellent viscosity-temperature properties. Lubricating function (anti-wear function). Thermal, oxidation stability, hydrolysis stability, shear stability. Excellent anti-emulsification. Excellent rust and corrosion resistance. Excellent anti-foaming and air release. Excellent sealing material adaptability. Excellent cleanliness and filterability.

Hydraulic transmission is used in transmission systems of many industrial sectors because of its advantages of small components, light weight, stable transmission, reliable operation, convenient operation, and easy to achieve stepless speed change. Due to differences in application requirements, operating conditions, and application environments, the hydraulic transmission systems used by different industrial sectors are also very different. 

Correctly selecting hydraulic oil varieties to ensure long-term stable and safe operation of the hydraulic system is an effective measure to ensure continuous production, save material consumption, and improve economic benefits.
