How to maintain the rotating parts of the hydraulic excavator

regularly check and replace the filter element

in order to prevent dust and impurities contained in the added oil from invading the main parts of the machine, protective measures are taken on the excavator. Several filters are installed on an excavator, and these filters play their respective important roles

(1) air filter

fresh air is required for the combustion of fuel in the engine. The air filter can remove the dust and other foreign matters in the air sucked into the combustion chamber from the outside, so as to prevent the wear of engine cylinder liner and piston ring

(2) oil and fuel filter

oil and fuel are easy to mix with moisture and dust during storage and refueling. The filter can filter foreign matters and prevent the wear of system components inside the engine. In addition, if the pollution of these filter elements is serious, it will lead to the failure of poor oil or fuel flow and engine damage caused by insufficient engine power or poor lubrication

(3) hydraulic oil filter

the function of hydraulic oil is to transform the medium of power, so it is strictly prohibited to mix dust and other foreign matters. The hydraulic oil filter can prevent impurities from entering all parts of the hydraulic device

in addition, the oil suction filter is installed in the hydraulic oil tank to protect the hydraulic pump in the hydraulic circuit. The oil after operation will return to the hydraulic oil tank, and the oil return filter is installed on the oil return part. Therefore, whether the pump or other parts of the hydraulic system are in an abnormal state can be judged by observing the pollution degree of the oil filter that does not affect the processing performance (such as whether there is iron filings)

when the oil passes through the above filter element, the impurities in it can be removed. Therefore, the pollution of the filter will become more and more serious over time. If the contaminated filter is not replaced in time, This kind of PCL material can be reduced by combining it with calcium phosphate which can be 3D printed (due to the flow of TCP oil, the original performance of the machine cannot be brought into full play. In addition, if you continue to use the damaged or excessively polluted filter, you will not be able to filter impurities, thus shortening the service life of the machine in the most widely used conventional plastic granulator equipment.

therefore, the filter element should be replaced regularly, and if any abnormality is found in daily maintenance and inspection, it should be replaced immediately.

in order to prevent machine wear, you should add Note enough oil and grease

during the operation of the hydraulic excavator, there will be great friction in all parts of the machine. Grease and oil can reduce these friction forces, because grease can form an oil film to prevent the metal parts of the rotating parts from contacting each other

filling oil and grease is an important operation, which is mainly to reduce friction and wear and make the machine run smoothly. However, if you do not add enough oil or add degraded grease, you will not be able to form an oil film and make metal parts contact each other, which will cause wear and seizure. If the machine continues to operate under this state, it will cause the burning of the mating parts of the moving parts of the machine, and will fall into the shutdown state in serious cases

therefore, sufficient oil and grease should be added regularly. Regularly checking and changing the oil in the oil tank is very important for the normal operation of the machine

to sum up, the maintenance points of the upper slewing platform of the excavator are: the structures of these fixtures have their own advantages and disadvantages

regularly check and replace the filter, and regularly fill enough oil and grease
