subject: The Measures For Emergency Repair Of Machinery [print this page] The measures for emergency repair of machinery
1, simple repair
If appear a sudden failure on construction machinery in the role or the process of moving, we should do a simple repair to enable it to reliably travel or effect. This year we met a TY-220 type bulldozer engine suddenly stopped job due to engine's connecting rod bearings burned out. Because the site has no replacement parts, so we adopt the solder welding, and then use the knife to repair the surface to smooth, the right size, clean installed, finally the diesel engine returned to work.
2, plugging
Construction machinery will produce the oil spill, leakage and leakage phenomenon, emergency plugging if long-term used, especially for construction machinery working in the tunnel, because of the limited working space, it is prone to appear hydraulic or diesel fuel tank collision leading to the failure of the leakage. Once this happens, we can use epoxy glue or soap to smear so that emergency plugging. If perforating, we can use cork, if necessary, use the wire or rope tied firmly. 3, replacing part
If construction machinery does field operation, it should be with a number of wearing parts spare parts in order to make the emergency replacement. Such as diesel engine cooling water pump seals water seal wear and aging will lead to water pump leaks, replacement of the water to win the title pump will return to normal. Of course, hydraulic cylinders, hydraulic pumps, hydraulic valve, replacement seal repair, are more effective. Also, if replacement parts assembly is even more simple and convenient, such as replacement of diesel filter or hydraulic oil, oil filter.
4, binding
By cable, wire and wooden clubs sticking if bolt breaking or slipping in construction machinery can not tighten the binding, and temporarily restore the running state. Such as the air pressure of 74 excavator institutions damaged, the front axle has been unable to connect, off-road performance of the machine, so that the suspension hydraulic cylinder can not latch. When connected to the front axle, fork shaft and the cylinder separation and look inside to push fork shaft, and then fixed in the fork shaft circle, so to ensure that the driver of the front axle. Similarly, if the suspension hydraulic cylinder or brake mechanism has lower or no pressure, may take such first aid methods.
