Regular maintenance is the basic guarantee for the safe operation and prolongation of service life of self loading mixer. The main purpose of routine maintenance is to find all kinds of faults and potential defects of the mixer in time, and then carry out effective maintenance, so as to avoid small problems from turning into big problems. As far as the self loading mixer truck is concerned, its daily maintenance mainly includes engine coolant level, battery inspection, brake level inspection, tire inspection, clutch master cylinder level inspection, etc. the key points of each part are briefly summarized below.
Never open the radiator cap when the engine of the charging mixer is in the hot state, otherwise you may be scalded by the splashed coolant or high-temperature steam
Engine coolant level check:
Never open the radiator cap when the engine of the charging mixer is in the hot state, otherwise you may be scalded by the splashed coolant or high-temperature steam. After the engine is cooled, check that the liquid level of the coolant should be between the full level and the low level, otherwise distilled water or purified water or refrigerant should be added, and the liquid level after adding water should not exceed the full level. If it is found that the coolant decreases rapidly in a short time, check the cooling system for leakage or go to the maintenance station for inspection.
Maintenance and inspection of battery:
Check whether the battery is firmly fixed, and the electrolyte shall be between the upper limit and the lower limit. When it is close to the offline, add electrolyte or distilled water to the high level line in time. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry. For the self loading mixer truck placed for a long time, the positive and negative cables of the battery shall be removed, and the wiring shall be re connected at an interval of about half a month. After starting the engine for about 20 minutes, if the power is obviously insufficient, it shall be charged in time.
Inspection of brake fluid level:
If the braking is also between high and low, it means normal. If the brake fluid of the self loading mixer truck is close to or lower than the lower limit, it indicates that there may be leakage in the system or excessive wear of the brake shoe, and it shall be repaired in the maintenance station in time. When adding brake fluid, pay attention to adding brake fluid of the same model to prevent damage to the leather cup, and pay attention to protect the paint to prevent corrosion of the paint surface.
Check the tire pressure at normal temperature every month. If it is lower than the normal standard, supplement the tire pressure in time. The air pressure shall not be too high or too low, otherwise it will affect the driving safety of the self loading mixer. Check the cracking of the tire. If there are potential safety hazards, replace the tire in time. When selecting tires, the models shall be consistent.
Check the fluid level of clutch master cylinder:
If the clutch fluid level is between high and low, it means normal. If it is lower than the standard line, the master cylinder or slave cylinder cup may be damaged. It will be difficult or impossible to shift when the engine is running. Please go to the nearest maintenance station for maintenance immediately.
