Analysis of the correct use of the lead battery of agricultural transportation vehicleAll agricultural transport vehicles that start the diesel engine by DC electric motors must have a battery. The chemical energy is converted into electrical energy when the battery is powered (discharge); when charging it, the electrical energy of the generator is chemically stored. Since the lead battery is low in other types of batteries, the capacity is high, and the use is safe and reliable, so it is favored by the majority of users. However, if the use of lead storage batteries and improper maintenance, it will also happen to people’s safety, and it is also easy to cause early damage to the battery. In order to enable the majority of users to properly use and maintain the vehicle lead battery, this paper only on the working characteristics of the lead battery in the agricultural transport vehicle, talk about the problems that should be paid attention to in use and maintenance.
1. The battery is installed firmly
The battery is susceptible to the shock during the driving process, which will not only loose the joint, but also break the battery shell. Therefore, the battery should be matched in the soft material, and the components should be fastened.
2. Use the starter correctly
In order to avoid excessive discharge, the startup time must not exceed 5 seconds each time; the second startup should be 2 minutes; if it is not started three consecutive times, it should be found before starting. Otherwise, it will damage the battery pole board too early.
3. Keep the liquid level height of the battery electrolyte
At charging, the chemical reaction in the battery is strong, the temperature is increased, the electrolyte evaporation causes the liquid level to drop, and the time is long and the polar plate will expose to air contact, so that the battery life is shortened. Generally, every 5 to 15 days in winter, after 5 to 6 days in the summer, the liquid level height of the electrolyte should be checked. The height of the liquid surface should be 5 to 10 mm high, and if the liquid level is insufficient, the distilled water should be immediately added to the liquid level height.
4. Regularly check the density and temperature of the battery electrolyte
It is generally checked for each after 15 days after work. The density and temperature measured by the densitometer and the thermometer were converted to a density at 15 ¡ã C, such as a density of 1.28, indicating sufficient battery power; if the density was 1.24, it indicated that the battery was discharged from 25%; if the density was 1.20, It indicates that the battery has been discharged from 50%. It should be noted that the battery’s winter discharge is more than 25%, and the degree of discharge in summer is more than 50%, it must be charged in time. In daily use, distilled water should be added in a timely manner to ensure the liquid level height of the battery, but should not add an acid electrolyte, otherwise it will shorten the life of the battery due to density disorders.
5. Timely and correctly charge
Excessive discharge of the battery will vulcanize the plate and affect its life. Therefore, the battery used in the car should be charged once every two months. Battery stored in electrolyte, supplemented once every two months. For icing batteries, it should be charged after Ice. The liquid level is checked before charging, and the distilled water should be added when the liquid is insufficient. When the vehicle is parked, the iron wire should be removed to prevent electricity. If re-enabled, you must check if the battery is sufficient. If it is not enough, it should be sufficient.
6. Keep the regulator charging voltage
The charging voltage of the general regulator is in the range of 11 to 14 volts, and it is not allowed to adjust any. Low, the battery is in a short state of charge, which will increase the vulcanization of the plate; it is high, the battery is overcharged, and the battery life will be shortened.
7. Battery with original specifications
The vehicle battery cannot use a large-capacity battery because the engine power on the vehicle is fixed, and the output current cannot increase or decrease, so the vehicle must be used as a prototype battery according to the original electrical design. If the battery is low in the car, some drivers will find enough batteries and the original batteries on the car, so although there is a lot of things, it has a big shortcomings. Because the battery-incoming battery in the parallel circuit is charged with a very large current, the battery is rated, and the rated charging current is high, and the polar active substance is easily detached and affects its service life. The correct method should be to remove the battery that is insufficient, replaced with a fully charged battery, and then start the engine.
8. Keep the outside of the battery clean
The battery-spilled electrolyte is stacked on the cover, mixed with dust, soil, easy to make the positive negative terminal forming pathway, causing self-discharge phenomena. In order to reduce self-discharge, apply a clean dry cloth to wipe the dirt on the cover during use, remove the oxide on the wiring column and wiring, and apply a thin layer of Vaseline or butter.
9. Keep the ventilation holes on the mixing hole
The battery produces hydrogen and oxygen during charge and discharge, especially when overcharged, water is electrolyte to produce a large amount of hydrogen and oxygen. The vent hole in the battery can be used to exist of these gases. In order to ignore the dredging of the vent, cause the vent to block, the heat generated during chemical reaction cannot be dispersed, which will increase the internal temperature and pressure of the battery, eventually cause the battery to explode. Therefore, attention should be paid to venting pores in daily maintenance to prevent dirt from blocking venting holes.
10. Battery power consumption

First check the boot, followed by some of the electric equipment, such as air conditioning motors, scraping motors, etc., therefore must be regularly maintained. The motor bearing should be used to lubricate butter lubrication, and the oil-containing bearing is soaked. In addition, the electric horn, the electric plug, the lighting line, and various types of control switches must be tandem the fuses, and must not be protracted from the battery pillars.
