In order to ensure the continuous and efficient operation of machinery and equipment, a set of scientific and systematic maintenance program is particularly important. The following is an in-depth analysis of the main points of maintenance of road rollers, to ensure that your project is carried out smoothly and efficiently.

First, transmission maintenance guide

The transmission should be cleaned and maintained at least once a quarter. Specific operation steps include: in hot condition, stop the car and unscrew the oil drain screw at the side end of the transmission, release the lubricating oil in the box; then re-tighten the oil plug, and pour kerosene into the box. Start the diesel engine, let the gearbox run at low speed for 2-3 minutes and then stop the car, drain out the kerosene and clean the oil plug thoroughly before reinstalling . In order to ensure the normal operation of the gearbox, it is necessary to regularly check and adjust the positioning devices of the speed change maneuvering mechanism and the reversing mechanism to keep the gears in the correct position to avoid derailment.

Second, the main points of the hydraulic system maintenance

Maintenance of the hydraulic system involves a number of components, including filters, valves, motors, pumps and cylinders. Regularly check whether the mounting bolts of these parts are loose, and whether there is oil leakage at the joints. At the same time, observe the oil level meter on the side of the tank to ensure that the hydraulic oil is sufficient, and when it is insufficient, the same grade and filtered hydraulic oil should be added. Hydraulic oil tank should be cleaned and replaced with new oil every six months.

Third, the vibration wheel maintenance method

The vibrating wheel needs to replace the lubricating oil every 1000 hours. When checking the oil level, you should turn the oiling port to the positive, and open the oil port, so that the oil leakage until no or little leakage. When replacing the lubricant, it needs to be kept clean. Vibrating wheels should be lubricated with CD grade No. 30 diesel oil. At the same time, the traveling bearing also needs to be lubricated and maintained on a regular basis, and a sufficient amount of calcium-based grease should be added to the corresponding oil cup position every 20 days on average.

Maintenance skill of main clutch

Maintenance of the main clutch needs to pay attention to adjust its operating mechanism at any time, and check and adjust the end of the release lever so that it is located in the same plane, and the release bearing to maintain a certain clearance (0.4 ~ 0.7 mm). When engaging and disengaging the clutch, it should be smooth and gentle, avoiding excessive force. At the same time, make sure that the clutch pedal is fully returned to achieve full engagement and that the pedal is pressed to the bottom when disengaging. In addition, the main clutch should be inspected regularly to avoid oil contamination on the surface of the friction plate and pressure plate.

Side-drive Maintenance Recommendations

Because of the low rotational speed, heavy load and easy to be contaminated by dust and sand, the side transmission should check its lubrication condition frequently, and remove the dirt on the gears and apply new grease regularly to prevent damage.

Six, battery maintenance measures

Battery maintenance needs to pay attention to the specific gravity of the liquid, charging voltage and discharge voltage and other indicators. If the battery acid salinization is found, it can be charged 1-2 times with smaller current to restore normal. At the same time, the charge of the battery pack needs to be checked regularly and charged as needed. In winter, make sure the battery pack is kept in a full state to prevent freezing. In addition, the surface of the battery needs to be kept clean, if there is dust or electrolyte outflow, it should be promptly wiped off with a rag dampened with ammonium chloride alcohol or 10% ammonium sulfate liquid.

Seven, diesel engine maintenance instructions

Diesel engine maintenance should be carried out in accordance with its use of maintenance instructions to ensure the normal operation of the machine and extend the service life.

Through regular cleaning, inspection, adjustment and replacement, we can effectively prevent failures and extend the service life of the roller, while improving efficiency and safety.
