The speed of the roadheader has nothing to do with pressure!

The speed of the roadheader has nothing to do with pressure! Shared the rock tunnel boring machine supplier.

The speed of the roadheader has nothing to do with pressure, but the speed of the roadheader has nothing to do with flow.

Part connection is not reasonable. Through many years of maintenance of the roadheader, it is found that part of the roadheader cutting cantilever section and cutting head use flange connection, this connection method cantilever section of the spindle section changes greatly, the stress concentration in the shaft shoulder leads to increased fatigue fracture tendency, overload may lead to the sudden fracture of the spindle.

When driving machine manufacturers into the machine operation, use cooling water, otherwise it will make the oil temperature rise driving machine can not work normally.

The oil absorption filter and oil return filter of the hydraulic circuit should be cleaned regularly, otherwise, mechanical impurities will enter the hydraulic system, making the hydraulic components wear out, resulting in leakage of the hydraulic system.

Mucking loader for  rock tuneling hydraulic system is composed of hydraulic pump station, cutting head lifting hydraulic cylinder shovel plate hydraulic cylinder. In order to maintain the hydraulic pump fault accurately and quickly, the phenomenon and process of fault point were found. The maintenance method is first component, then component, first external and then internal, first simple and then complex, layer upon layer dissection.

The speed of the roadheader has nothing to do with pressure, but the speed of the roadheader has nothing to do with flow.

When the rock roadheader stops working, maintenance and shift, disconnect the disconnecting switch on the machine and hang the power failure sign.

For machine operation and problems, the shift driver to the replacement driver to explain.

When the gas concentration in the wind current within 20 meters before and after the roadheader reaches 1.5%, stop the operation, cut off the power and conduct treatment.

When the machine is running, use cooling water, otherwise the oil temperature of the roadheader will rise and the roadheader will not work normally.

Mechanical, electrical, hydraulic system, protection device should be normal and reliable, parts and components should be intact, each part connection screw should be complete, fastening.

The cable clips of the connecting devices of the electrical system should be complete and firm, the cable should be hung neatly without any damage or extrusion.

The joint of hydraulic pipeline and atomization pipeline should be free from damage and leakage, and the protective device should be complete and reliable.
