Tobacco farmers, the timing of the spring season in the field is a key period for the use of tractors. It is very important for the maintenance of the tractors. In order to improve labor efficiency, the tractors must be “10 taboos†for maintenance and repair. Hopefully this will help you.
One bogey tighten the screws and bolts
Screws and bolts in important parts of the tractor transmission case, cylinder head, hub, connecting rods, and front axle, etc., are specified in the instructions in the use of tools and tightening torques. For example, artificially tightening can cause screws or bolts to break and thread slipping. Or pull the buckle and cause a malfunction. Ordinary screws or bolts, the tightening torque can be tightened by 4 times the tightening torque of the thread diameter.
Second avoid replacement of oil does not clean the oil
Some agricultural operators lack maintenance knowledge or are lazy. They do not clean the oil passages when replacing lubricants, thus burying potential safety hazards. It should be noted that after the lubricating oil is used, there are many residual mechanical impurities in the oil. Even if the lubricating oil is drained, there are still impurities in the oil pan and the oil passage. Especially after a new or overhauled locomotive, there are more impurities after the trial operation. If you do not clean the oil gallery and you are eager to put it into use, it is very easy to cause accidents such as burning tiles and holding shafts.
Three bogey don't use lubricants according to the season
Some farmers do not pay attention to the use of lubricants according to the season, the use of summer lubricants in winter, the use of winter lubricants in the summer, even regardless of quality, cheap to buy, resulting in locomotive start difficulties and burning bush and so on. Therefore, the agricultural operator must select the lubricating oil that has passed the quality test and the applicable temperature label.
4 bogey installation piston with open flame heating
The uneven thickness of the various parts of the piston, the thermal expansion and contraction are different, easily lead to deformation. If the piston is heated with an open flame to a certain high temperature, the metal structure will be damaged after the natural cooling, which will reduce the wear resistance and greatly shorten the service life.
Five bogey when installing the cylinder pad butter
Some agricultural operators are used to applying butter when installing cylinder head gaskets. They think that this can increase the airtightness of cylinders. I do not know if they are counter-productive. Due to the partial loss of butter after high temperature, there is a gap between the cylinder pad, cylinder head and the plane of the machine body. High-temperature and high-pressure gas can easily impact from this place, destroying the cylinder pad and causing air leakage. In addition, the butter will produce carbon deposits at high temperatures for a long time, resulting in premature aging of the cylinder mats.
Six bogey to place the throttle at the maximum fuel supply position
When some farm tractors start the locomotive, they are used to putting the throttle at the maximum fuel supply position. This will inevitably cause too much fuel to be injected into the cylinder. The mixture is too concentrated and difficult to start. The scientific positioning of the throttle is: When the temperature is above 15C, it is slightly higher than the idle speed; when the temperature is below 15C, the crankshaft should be idle for a few revolutions, and when it is easy to feel, start with a small throttle. In addition, do not avoid the throttle, to prevent the sudden fluctuation of the speed, fuel and air mixed unevenly, so that parts of the cylinder such as carbon deposition, or cause the connecting rod bending, crankshaft fracture and other accidental failure.
Seven Bogey Does Not Carefully Check and Care for New Cars
Some young agricultural operators mistakenly believe that with the development of science and technology, the current safety performance of locomotives is very reliable. Therefore, after a new car is bought, it will not be seriously checked and maintained except for the trial run. As a result, the problem is frequent and there is no trace of regret. To do this, you should do the following inspection and maintenance work: First, check whether the oil in the oil filter in the three-stage air filter is organic oil. The second is to check the fastening of the bolts in various locations. The third is to check and adjust the injection pressure. The fourth is to change the oil in the oil pan, and clean the oil pan and lubricant road.
Eight Bogeys Water Tank “Cooking Pan†When Adding Cold Water
Most agricultural operators know that overloading of the engine, lack of water in the tank, and poor heat dissipation will cause the tank to “open.†If the temperature is too high, adding cold water will cause the cylinder head and cylinder to “blowâ€. Therefore, once the tank is found to “open potâ€, the agricultural operator should take emergency measures to ensure that the engine cooling water cools itself.
Nine bogey hurry to increase labor efficiency
Some agricultural machinery experts believe that the rapid increase in labor efficiency, but I do not know how it is closely related to the amount of fuel consumption. It has been verified by practice that the locomotive accelerates from the start to the moderate speed (30 km/h), and the fuel consumption with rapid acceleration (25 seconds) is approximately equal to twice the fuel consumption of slow acceleration (40-50 seconds), and the speed is accelerated. There is nothing to lose. Therefore, the farmer should take a low-speed start and then accelerate slowly.
Ten hanged oil instead of brake oil, gear oil
In the production practice, the phenomenon that some farm machinery operators use engine oil instead of brake oil and gear oil is quite common, and various accidents have been caused. It should be noted that the brake fluid is the medium for the transmission of pressure in the hydraulic braking system of the locomotive. The main components are castor oil and alcohols. Their solubility is good and they are not easy to precipitate and corrode. Contact with the rubber body can make the expansion rate of the rubber body smaller. . The oil does not have these excellent characteristics. If oil is used instead of brake fluid and gear oil, precipitation will occur easily, and the rubber parts of the brake system will swell, which will easily lead to brake failure. Compared with gear oils, oils have low viscosity and weak compressive, wear-resistance and load-bearing capacity. If oil is used instead of gear oil, the transmission gears are not easy to hang on the oil film and the lubrication effect deteriorates, causing premature wear of transmission gears, etc. Bad phenomena occur.
