The operational efficiency of equipment can be expressed as the annual consumption cost of annual capacity of the annual operating hours of the book table, and the latter two are related to the transport distance and stripping ratio. The measurement cost of the annual operating hours of Taiwan and Taiwan can generally represent the operational efficiency can not be ignored. At present, except for the Antaibao Mine, other mines have a large gap with the United States in terms of operational efficiency. Take the dump truck as an example. Hours of maintenance hours are the visible gaps between China and China. Domestic equipment operations are short and maintenance takes a long time. The reason is that the quality of equipment is not high, the management level is not high, the maintenance problem has not been completely resolved, and the spare parts supply is not timely. 2. Problems and Improvement Opinions on the Repair of Doors As mentioned above, the main problems in management are the lack of computer network management, the inability to grasp the various data of equipment operation, the discovery of problems, and the timely improvement. In the future, we should raise it as soon as possible, with reference to Antaibao. It should be emphasized that the implementation of a full mine network requires a relatively negligible cost compared with the increase in operational efficiency. The outstanding problem in maintenance is that the assembly repair problem has not been resolved and the maintenance center has not yet been built. The Huolin River was expanded on the basis of the original pit maintenance room and reluctantly took on some tasks. The Yimin River in Yuanbaoshan was designed without considering the maintenance center. Zhungeer has designed a maintenance center, but construction has not been approved. Therefore, the repair of each mine's assembly is very difficult, which is one of the main reasons that affect the operational efficiency of the equipment. Assembly is a key part of the equipment, such as diesel engine gearbox torque converter crankshaft electric wheel cylinder oil motor and other large parts to use special tools to repair the use of advanced test equipment to check the quality of repairs, currently do not have these means, unrepaired, there is The quality is not high, and the cumulative repair time is long.
The xunda Heat Shrinkable Tape is a wrap around radiation cross linked tape designed for corrosion protection of straight pipes, fittings, bends, elbows and other irregular configurations. When heated the backing layer shrinks and the adhesive flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.
The Epoxy Primer should applied to the prepared pipe surface then heat shrinkable tape is immediately wrapped around the joint over the wet epoxy.
Then center the closure patch on the overlap region.
The pipeline heat shrink tape consists of three layers, primer layer, adhesive layer, film backing.
Primer: Liquid epoxy, solvent free two component.
Adhesive: High shear strength copolymer adhesive
Film backing: Radiation cross linked. High density polyethylene
