The hydraulic system of hydraulic support is mainly composed of power cylinder, control valve and pipe fitting. The concentrated liquid products of hydraulic support can effectively protect the hydraulic system of the equipment and extend the service life of the support equipment. They are widely used in mining and mining, and the performance requirements of concentrated liquid products are higher in the coal industry.
1, with reliable security. Concentrate products should not be able to ignite and, of course, not be able to help ignite to ensure the safety of coal mine production.
2. Viscosivity: The viscosity of the concentrated liquid product is close to that of water. Reduce the energy consumption in the work, and better viscosity-temperature performance is also conducive to the pump station and the stability of various valve performance.
3. It is required to have good anti-corrosion. Because the concentrate products contain components that prevent rust and corrosion, good quality products can even overcome salty mine water, reducing corrosion and extending the service life of the equipment.
4, lubrication and sealing material adaptability is better, excellent lubrication performance and sealing material compatibility, can effectively avoid leakage, so as to reduce maintenance and material consumption costs.
5, good stability. Because the concentrated liquid products contain emulsifiers, coupling agents and anti-foaming agents, the stable emulsifying system can produce stable oil-in-water emulsion, avoid oil-water separation, and is not easy to produce bubbles, and has good chemical stability. Ensure the normal operation of the equipment.
6. Concentrate products are not harmful to human body, have no irritating odor, no odor, and do not pollute the environment.
7. Economy of use: Usually fully mechanized mining face has nearly 100 hydraulic supports, or even as many as 150. Due to the small viscosity of concentrated liquid, easy leakage, lubrication is not as good as mineral oil, it requires better sealing performance and rust prevention performance for emulsion pump and hydraulic valve. Therefore, the use of more cost-effective concentrate products to reduce concentrate leakage and liquid consumption can reduce the overall cost of use.
