1. Pollution problems
1 The main reason for the failure and failure of hydraulic components is that there are pollutants in the hydraulic oil.
2 Contaminants in oil have various forms and come from different sources.
3 Therefore, the pollution control of the hydraulic system should be based on the root cause of the pollutants, and take effective measures against the disease.
2, leakage control
1 The oil in the hydraulic system should flow or stay in the cavity or pipeline of the hydraulic component, and different chambers often have different pressures.
2 If the oil crosses the boundary for some reason and flows to other chambers or systems outside it, this is a leak.
3 Leakage from the high pressure chamber to the low pressure chamber is an internal leak, and leakage from the component or the pipeline to the outside is an external leak.
3, noise control
1 Noise is a public hazard.
2 There are certain restrictions on the noise of industrial enterprises or workplaces.
3 The main noise source of the hydraulic system is the hydraulic pump. The noise reduction of the hydraulic pump has been significantly improved after years of domestic efforts.
4, factory test
1 Before the hydraulic system assembly is delivered, at least the cleanliness inspection, pressure test, sealing test and functional test shall be carried out.
2 functional tests include: pump operation function test, circuit function test and noise test.

The hydraulic two-arm Bolting Jumbo for coal mines is a new type of roadway support mechanical equipment. The machine is used in conjunction with the roadheader and the drilling unit to quickly complete the support work, achieve operational balance, and improve mechanization. Mainly used for coal rock and semi-coal rock roadway working face support operations. It can simultaneously realize the support of roadway top and side bars with bolts and cables. It also has the functions of drilling blast holes and detecting holes (water control, gas detection) in the coal seam.
