Overview :
The concentrated liquid for hydraulic supports is a high-performance working medium specially developed and designed for the hydraulic transmission systems of hydraulic supports. After being diluted and mixed with water in a specific proportion, it can be applied to the daily operation of hydraulic supports in underground coal mines, providing reliable power transmission, lubrication, rust prevention and other aspects of guarantee for hydraulic supports. It is a key supporting product to ensure the safe and efficient production of fully mechanized coal mining faces.
Product Characteristics:
Exceptional Stability: It can quickly and evenly dissolve with different water qualities and will not separate into layers or precipitate oil even when left standing for a long time.
Outstanding Lubricating Performance: Containing high-performance base oil and multiple additives, it can extend the service life of the equipment.
Remarkable Anti-rust and Anti-corrosion Performance: There is a special combination of additives.
Good Anti-foaming and Air Release Properties.
Excellent Resistance to Hard Water: It can adapt to the complex water sources underground and has good tolerance to high-hardness mine water, without precipitation or scaling problems.
It is widely applicable to the hydraulic systems of hydraulic supports in various underground coal mines. Meanwhile, it is also suitable for other hydraulic equipment under similar working conditions underground, such as the hydraulic pushing devices of scraper conveyors.
