Agricultural vehicle maintenance and maintenance

In the process of operation, the working performance of the vehicle will decrease with the changes of parts wear, deformation, corrosion, looseness and fit gap, etc., resulting in the technical performance and working capacity of the vehicle, which leads to difficulties in starting, insufficient power, increased fuel consumption and even failure or accident. Daily maintenance and maintenance is to regularly check, clean, tighten, lubricate, add, adjust and replace some vulnerable parts according to the deterioration of technical condition.

(1) tighten. For the fastening bolts that bear dynamic loads and are easy to cause serious accidents, such as the fixing bolts of cylinder head, connecting rod bearing, flywheel, etc., the fastening force is strictly required and should be tightened according to regulations. Some bolts (such as cylinder cover bolts) on new or overhaul cars will produce initial elongation after test run and should be tightened in time.

(2) clean. Keep the exterior of the vehicle clean. Pay attention to proper cleaning agent and proper cleaning method for internal cleaning.

(3) to adjust. Strictly follow the technical maintenance procedures.

(4) the lubrication. Fill the lubricating oil and grease timely, and make sure it is clean and free from leakage.

What should be paid attention to when using and maintaining batteries for agricultural transport vehicles?

(1) in the process of use, dust soil around the battery should be frequently removed, oxide on the pole pile and wire connector should be removed, and electrolyte on the battery cover should be erased. The connection should be firm and reliable.

(2) check whether the battery is installed firmly in the vehicle, and ensure that the wire joints are tight and in good contact.

(3) do not discharge large current for long time. When starting the engine, the time for each start shall not exceed 5 seconds, and the interval between the two start times shall be 15 seconds. At the same time, the horn shall not be played for a long time.

(4) no large current charging or overcharging. The voltage regulation value of generator regulator should be adjusted strictly according to regulations. It is proved that the charging voltage is increased by 10%, and the battery life will be shortened by 2/3.

(5) the battery should be charged regularly to ensure that it is working under sufficient power. The battery should be charged within 24 hours after it is finished.

(6) when using the battery in winter, special attention should be paid to keep the battery fully charged, so as to prevent the electrolyte from freezing due to the reduced relative density, causing the shell to break.

(7) if the battery is not used for three months, it should be put in a cool and ventilated place after being fully charged. At the same time, the relative density of electrolyte should be checked regularly to keep the battery in the state of sufficient electricity. If the battery is not used for a long time, discharge the battery at the rate of 20 hours, pour out the electrolyte, rinse with distilled water for many times, until the water is acidic, cool dry, then screw the hole cover, seal storage.
