Application of hydraulic hose for excavator in mine

The hydraulic tubing of excavator is the special hydraulic tubing in the hydraulic system of the excavator, and there are two kinds of hydraulic tubing and hydraulic tubing of the hydraulic pipe.Classification: excavator large arm pipe, excavator small arm hydraulic tubing, pilot tube, broken hammer hydraulic hose, etc.;Parameters: high temperature resistance, high pressure, high pulse, etc.Features: operating temperature range: - 40℃ to 100 ℃.Pulse frequency: more than 600, 000 pulses.Maximum working pressure: 42.5Mpa.Life span: more than 3 years.Because of its poor working environment and working content, the crushing hammer requires the driver of the excavator to choose the broken hammer pipe with suitable price and performance.

Special hose for coal mining equipment

    1. When the hydraulic hoses are installed in coal mine hydraulic supports and integrated shearers, they must be properly installed according to the hydraulic pipe installation specifications. 2. For hydraulic hoses that are not installed and used, the following points should be made for daily storage. The stacking should not be carried out. Sharp objects should not be rubbed during storage; they should not be mixed with chemicals. 3. If oil leakage or hose breakage occurs in the process of use, it should be replaced in a timely manner. Do not continue to operate under abnormal conditions. 4. During use, the mine hose cannot be strongly stretched; the pressure and high temperature or low temperature must be within the product specification. Cracked oil spills cannot continue to be used and must be replaced in time. 5. Because of its poor working environment and work content, the hammer requires excavator drivers to choose a hammer with suitable price and balance performance. The latest hydraulic tubing assembly quotation please contact online customer service. 6, the transmission medium must be the design of the fluid medium for the product; working pressure, working temperature can not exceed the scope of the hose. 7. The length of the hose should be suitable. Too long or too short and the difference in diameter will lead to shortened hose life. Hesitation Hose structure is more complex, daily transportation and storage process, the hose should not be distorted. Once there is a problem with the wire winding hose, it must be stopped immediately and replaced in time!
