First said the excavator, excavator accessories manufacturer, also known as mining machinery, is higher or lower than scoop mining machine surface material, and load transport vehicles or discharge to stocking yard of earth moving machinery, has become one of the main engineering machinery in engineering construction.
Excavator digging bucket actually not difficult to operation, but the scoop of the maintenance for many people, implement a regular excavator maintenance aims to reduce the drivers fault, prolong the service life of the excavator.
But in the process of practical maintenance, machinist by mining is not good to maintenance, often maintain a & other;
Damage & throughout;
Today, excavator accessories factory small had to count to you excavator digging bucket maintenance, absolutely can't do, and see it together!
1, the start method is undeserved cause serious damage to the machine in winter, some drivers for quick start engine, often using anhydrous start (
First start, then add water)
Abnormal startup method.
It can cause serious damage to machinery excavator attachments
, shall be prohibited from use.
The correct preheating method is: first the heat preservation quilt on the tank, open the drain valve, continuous injection 60 - to the tank
70 ℃ clean soft water, touch feel hot water flowing from water drain valve, then close the drain valve and shipped 90 - to the tank
100 ℃ clean soft water, and turn the crankshaft, make each moving part properly lubricated beforehand, and then start again.
2, do not pay attention to the body heat preservation to reduce the working life, damage to the engine low winter temperatures, easy to make the diesel engine work excessive cooling.
So the thermal insulation is the key to good winter with diesel engine.
In the north, the winter use diesel engine shall be equipped with heat preservation and insulation curtains and other protective equipment.
3, casually use fuel to reduce the engine life, increase the damage probability of winter low temperature keep the liquidity of diesel, viscosity increases, spray powder not easily, cause atomization, burning, resulting in a decline in the power performance and economic performance of the diesel engine.
So the winter should choose and ignition performance good light diesel oil with low freezing point.
General requirements, the freezing point of diesel engine should be lower than the local lowest temperature 7 - the current season
4, low load operation machine caused by serious wear was burning diesel engine start, some drivers can't wait to immediately load operation.
Diesel engine fire soon, because the body temperature is low, oil viscosity, oil is not easy to filling the motion pair of friction surface, can cause excavator machine accessories serious wear and tear.
In addition, the plunger spring, valve spring and injector spring because & other;
Cold short & throughout;
It is easy to break.
5, with flame baking oil sump or burning machine, light machine wear in order to avoid making within the oil sump oil deterioration, even burning, lubrication performance degradation or complete loss, exacerbating excavator attachments
Winter should choose low condensation point of the oil, startup can be closed to water bath heating method is adopted to improve the oil temperature.
To correctly maintain excavator digging bucket, don't let the wrong maintenance becomes the origin of the damage to the machine.
