Construction machinery in use in emergency response to sudden events will teach you 9 ways

1, Maintain

Construction machinery in the operation or process, if it suddenly fails, simple repair method should be used in order to make it reliable or operations. As bulldozers in the job when the engine suddenly stalled, dismantling the find engine connecting rod bearing burned out. As no parts replacement, and solder welding, and then the surface with a knife to smooth, repaired the right size, after clean installation, diesel returned to work.

2, Leakage

Construction machinery used for a long time, will produce oil spills, leaking and leaking phenomenon, emergency blocking, more suitable for long in tunnel construction in construction machinery, due to its limited working space, prone to hydraulic or diesel fuel tank leakage fault due to a collision. If this is the case, use epoxy cover or smear with SOAP, emergency leak. If pierced, Cork entertainment, with wire or rope tied when necessary. If the oil spill because of loose fitting, available random distribution with tape on the thread wrapped around 3-5 circle, to tighten them.

3, Change

Engineering machinery field work should bring some consumable spare parts as much as possible, to enable emergency replacement. Diesel engine pump seals water seals worn and aging will cause water pump leaks, replaced new water pump will return to normal work after closure. Of course, the hydraulic cylinder, hydraulic pump or hydraulic valve, replace the seal repair, are working. Also, if we can replace the mechanical Assembly is more simple and convenient, such as replacing diesel fuel filter oil or hydraulic oil filter.

4, Tied up

Construction machinery somewhere on the bolt when they cannot be fastened or sliding buckle, may consider the application of wire and sticks, lashing, make it temporarily to restore operation. Type 74 excavator pressure body damage, the front axle has been unable to connect, the off-road performance of the machine, make it impossible for its suspension hydraulic cylinder closed. When you need to connect the front axle, fork shaft and cylinder can be separated and to push the fork shaft, and then in shift fork shaft rings fixed, thus ensuring the front axle drive. Similarly, if suspension hydraulic cylinder or brake mechanism when there is less pressure or no pressure, may adopt this method of first-aid.

5, Demolished

On the premise of not affecting the operation of construction machinery, detachable stretch out unused and damaged parts. For example, the damaged diesel generators can be removed, temporary short-time power supply battery starting System. Director of parts after demolition after a simple repair, emergency use. Such as gas producing diesel engines damaged, grinding it detachable, restoration and sealing of the valve seat, can be used.

6, Short circuit

Engineering machinery and starting system or a component in a control circuit is damaged, can neither repair nor replacement of spare parts, such as usage allows, consider short circuit, and emergency use. But not long-term use often increases after the short circuit in the heat, it is possible to burn other circuit elements, conditions damaged components must be replaced immediately to prevent new failures

7, Supplement

Low pressure hydraulic hose is damaged, other pipes that are available to restore the original length to facilitate emergency repair. For example, diggers, tubing due to long-term use of aging or wear, caused when the pipe ruptured and cannot be blocked, without tube replacement, they can be damaged parts cut out, put plastic or rubber tube, fit over the ends of the tubing and solid prison, conduction can be.

8, Suspend the use

Driving on the job or in the construction machinery, circuit or hydraulic system is damaged, it can be damaged partially broken, not used. Such as somewhere in the engine starting system wiring up iron discharge, sometimes cannot be ruled out, left vacant could be positive power to power ignition system, so that first aid. If several parallel branch-circuit hydraulic system one fails, then remove the inlet pipe and plug seal, so that other branch circuits may continue to work, to be repaired in a timely manner when the job completed.

9, Replacing the

When certain parts of construction machinery is damaged so that they do not work, car will not affect the work of other components or components produced locally instead, but this method of repair to make the project worse mechanical properties recover, usually only used in its no-load operation. For example, the compact excavator fan belt, belt, backpack available in a short time with a braided belt, instead.
