The hydraulic system of an electric forklift truck is a key structure that supports core operations such as lifting and tilting. Doing a good job of corresponding maintenance can not only reduce the probability of unplanned downtime, but also effectively prolong the overall service life of the equipment. The following is a detailed description of the key points of hydraulic system maintenance for CPD18S models.
Daily routine inspection points
Hydraulic oil level inspection
Before each operation, check the oil level scale of the hydraulic oil tank to ensure that the oil is within the specified range. When checking, lower the fork to the lowest position and let it stand for a few minutes until the oil is completely returned to the tank before reading the scale to avoid reading deviation. If the oil level is lower than the standard line, add qualified hydraulic oil of the same specification. Do not mix and add different types of hydraulic oil.
Appearance investigation of hydraulic pipeline
During daily inspections, check all exposed hydraulic pipelines one by one to confirm that there are no problems such as oil leakage, bulging, and outer cracks. If any minor oil leakage is found, confirm the tightness of the joints in time, and tighten the joints according to the standard torque. Do not operate with faults for a long time.
Regular deep maintenance operation
Hydraulic oil replacement specification
Replace the hydraulic oil regularly according to the requirements of the equipment's use time. When changing the oil, it is necessary to clean the impurities deposited at the bottom of the tank synchronously to avoid the particles in the old oil from entering the new oil circulation path. After the replacement is completed, it is necessary to test the lifting action multiple times without load to confirm that the system exhaust is completed before putting it into formal operation.
Hydraulic parts cleaning and maintenance
Regularly clean the exposed piston rod parts of the hydraulic pump and oil cylinder, and promptly clean the attached dust, grit and other impurities to avoid impurities from being brought into the cylinder with the action to scratch the seals. Do not use highly corrosive solvents when cleaning, and use a soft cloth that does not shed hair to wipe.
Common exception anticipated handling
If you find that the lifting action card and oil pressure are unstable during daily operation, stop the operation as soon as possible, check whether the hydraulic oil filter element is blocked, do not force high-load operation, and restart the equipment after the investigation is completed to confirm that there are no hidden dangers. During the daily maintenance process, make corresponding records to facilitate subsequent traceability of the running status of the components, and gradually optimize the operation and maintenance rhythm of the equipment.
