Hydraulic support concentrate is a composite product based on water, with good hydrophilicity, better stability than traditional emulsion oil, suitable for coal mine hydraulic support, machinery industry, metallurgy industry hydraulic system as the transmission medium, but in the use of hydraulic support concentrate can not be blind, also need to remember the relevant technical indicators, in order to help you better application, The following article explains the details for you.
First, the adaptability of sealing materials
The lack of damage and significant effect between the concentrate of the hydraulic support and the various materials in contact with it is referred to as adaptability or compatibility with the material. The hydraulic system has a variety of metals, rubber, plastics, coatings and other materials, and the concentrate should be compatible with them. Rubber seals and nylon, plastic, leather and other sealing materials are widely used in hydraulic systems. Hydraulic support concentrate should be selected for compatibility with the system sealing material. If it is not suitable for the sealing material, it should not be used. If the new concentrate is significantly superior to the original concentrate but is not suitable for the system's sealing material, other sealing materials suitable for the concentrate will need to be used.
Two, ventilation
Foaming refers to the tendency of the oil product to produce foam and the stability of producing foam, and air release refers to the ability of the oil product to release the bubbles dispersed in it. The air can be mixed with the hydraulic system, dissolved and mixed in the hydraulic support concentration. The amount of air dissolved in the oil is proportional to the absolute pressure. The mixed air is suspended in the oil by bubbles.
Third, cleanliness
The cleanliness of hydraulic support concentrate refers to whether there are water and mechanical impurities in hydraulic support concentrate. When the concentrate enters the water, the harm is the same as other lubricants. It is important to note that concentrates using silicates or phosphates as base oils will hydrolyze when they encounter water, producing corresponding acids that will corrode metal components. Therefore, there should be no water in the concentrate. If there are mechanical impurities in the hydraulic support concentrate into the hydraulic system, it is easy to damage the working surface of the hydraulic components, thus greatly shortening the service life of the hydraulic components. In order to ensure the normal operation of the hydraulic system and improve the service life of the hydraulic components, the concentrate entering the hydraulic system needs to be very clean and does not allow the concentration of solid particles and other dirt beyond the limit.
