Do not hurry construction machinery nine strokes to solve emergency repair
In engineering machinery, often encounter unexpected situations, how to quickly solve the problem, to avoid more losses, each boss is concerned, the engineering machinery home today Xiaobian teach you a few action.
1. brief repairs
Construction machinery in the process of operation or driving, if the sudden failure, should be used to repair a simple method, so that it can reliably drive or operation.
Such as a bulldozer in the operation of the engine stalled, we found that there was burnt out engine connecting rod bearing.
Because there is no replacement on the spot, the solder repair welding is used, and then the surface of the knife is repaired to smooth, smooth and suitable size, cleaned and installed, and the diesel engine is restored to work.
2. plugging
The use of construction machinery for a long time, will produce Water Leakage and oil spills, leakage phenomenon, emergency plugging, more suitable for construction machinery in the tunnel for a long time, because of the limited working space, prone to hydraulic or diesel fuel tank due to collision caused leakage fault.
Once this happens, can supplement the epoxy resin or use soap daub, emergency plugging. If there is a perforation, available cork hospitality live, if necessary with a wire or rope bound.
If the oil leakage is caused by the pipe joint loose, the rubber belt with the random belt can be screwed 3-5 times at the thread, then it can be screwed down.
3. exchange parts
Engineering machinery field operation, should try to bring some more vulnerable parts of spare parts, in order to make emergency replacement.
For example, the seal of the cooling water pump of the diesel engine will cause the water pump leaking because of the water seal wear and aging. After replacing the new water seal, the water pump will return to normal.
Of course, the hydraulic cylinder, hydraulic pump or hydraulic valve, replace the seal repair, are more effective.
Also, if you can replace the parts assembly is more simple and convenient, such as the replacement of diesel filter or hydraulic oil filter, etc..
4. bundling
When a bolt is broken or slipped on the construction machinery, it can not be fastened, so it can be used to tie the wire and stick together so as to temporarily resume the running state.
For example, when the pressure mechanism of 74 excavator is damaged, the front axle of the excavator can not be connected, and the performance of the machine is decreased, so that the suspension hydraulic cylinder can not be locked.
When the front axle needs to be connected, the shifting fork shaft and the cylinder can be separated, and the fork shaft is pushed inwards, and then fixed in the circle of the fork shaft, so that the drive of the front axle can be ensured.
Similarly, if the suspension hydraulic cylinder or the brake mechanism appears the barometric pressure drops or does not have the barometric pressure, may take this kind of first aid method.
5. disassembly
In the premise of not affecting the operation of engineering machinery, mechanical stretch out and detachable temporarily not damaged.
For example, the diesel engine has damaged the generator remove temporary battery to start short-term electricity.
Some parts removed after a simple repair, and can use the emergency.
If the gas production of the diesel engine is damaged, it can be disassembled and ground, and the seal of the valve seat ring can be recovered basically.
6. short circuit
If a part of the starting system or control circuit of the construction machinery is damaged, it can not be repaired and no spare parts are replaced. If it is used, the short circuit connection can be considered and the emergency use can be taken.
But it can not be used for a long time, because the short circuit connection will often increase the calorific value of the circuit, it is possible to burn other circuit components, when conditions must be replaced immediately damaged components, in order to prevent new faults.
7. supplement
Low pressure hydraulic oil pipe is damaged, can be restored to the other pipe length, to facilitate emergency repair.
For example, excavator, due to the long-term use of the tubing aging or wear, leading to pipeline rupture and when not blocked, without preparation of pipe replacement, the damaged part cut off, the plastic tube or a rubber tube is sheathed at both ends of the tubing firmly, can be conducted.
8. suspension of use
In the operation or driving of construction machinery, if the circuit or hydraulic system is damaged, the damaged part can be broken off and temporarily used.
Such as wire bonding discharge engine starting system somewhere, time has not ruled out, the cathode hanging off, only for the ignition system for emergency power supply. If several parallel branch circuits in the hydraulic system of a failure, this time can be removed and the inlet pipe plug seal, so that other branch circuit can still continue to work until the operation is completed timely repair.
9. alternative
When a part of engineering machinery damage so that it can not work when the car can temporarily affect the work of other parts or materials manufacturing parts to replace, but this maintenance method make the engineering mechanical properties was poor, usually only used in the no-load running.
For example, the small excavator fan belt, in a short period of time can use tape, backpacks and other woven belt to replace.
Under normal circumstances, the use of the above methods can temporarily let your machine run, the best way is to quickly come to the engineers will repair the machine
