Routine maintenance and maintenance of agricultural vehicles
During the use of the vehicle, the working performance of the vehicle will wear out, deform, corrode, loosen, and change the gap, etc., which will degrade the technical performance and work ability of the vehicle, cause difficulties in starting, power shortage, fuel consumption increase, and even failure. ACCIDENT. Routine maintenance and maintenance is based on the degree of deterioration of its technical status, systematically inspect, clean, tighten, lubricate, add, adjust, and replace certain vulnerable parts.
(1) Fasten. For fastening bolts subjected to dynamic loads and prone to major accidents, such as cylinder heads, connecting rod bearings, flywheels, etc., the fastening bolts have strict requirements and should be tightened as required. Some bolts (such as cylinder head bolts) on new or overhauled vehicles will have initial elongation after trial operation and should be tightened in time.
(2) Lubrication. Fill lubricants and greases in a timely manner. When adding, be sure to clean and prevent spillage.
(3) Clean. Keep the outside of the vehicle clean, and pay attention to the use of appropriate cleaning agents and proper cleaning methods for internal cleaning.
(4) Adjustments. Strictly follow technical maintenance procedures.
Agricultural vehicle battery use and maintenance pay attention to what?
(1) During use, the dirt around the battery, the oxides on the poles and the wire connections, and the electrolyte on the battery cover should be wiped off. The wiring should be solid and reliable.
(2) Regularly check whether the battery is firmly installed in the vehicle and ensure that the wire connector is tight and the contact is good.
(3) It is prohibited to discharge large currents for a long time. When starting the engine, the time for each start shall not exceed 5 seconds, and the interval between adjacent two starts shall be 15 seconds apart. At the same time, the electric horn shall not be sounded for a long time.
(4) Can not charge and overcharge with high current. Generator regulator voltage regulation value should be adjusted strictly according to regulations. Practice has proved that a 10% increase in charging voltage will shorten the battery life by 2/3.
(5) The storage battery should be charged regularly to ensure that it operates in a fully charged state. The discharged battery should be fully charged within 24 hours.
(6) When using the battery in winter, special attention must be paid to maintaining a fully charged state so that the electrolyte freezes due to a decrease in relative density, causing the shell to crack.
(7) If the battery is not used for three months, fully charge the battery and put it in a cool and ventilated place. At the same time, the relative density of the electrolyte should be checked regularly to keep the battery fully charged. If it is not used for a long time, first discharge the battery at a discharge rate of 20 hours, pour out the electrolyte, and rinse it with distilled water several times until the water is not acidic. After cooling, tighten the hole cover and seal it for storage.
