Correct purchase of new corn thresher

Long-term use of mechanical equipment requires maintenance, and the new corn thresher is no exception. The new corn thresher is mainly used for its high performance. Therefore, the maintenance of agricultural machinery directly affects the service life and performance of agricultural machinery. Let me introduce how to prevent the new corn thresher from rusting?

       First of all, most parts of agricultural machinery are made of iron. Such iron parts should be cleaned when not in use, coated with anti-rust paint, and stored in a ventilated and dry place.

       Secondly, the new corn thresher is placed in a dry and ventilated place. When the wheel harvester and tractor are put into storage, the wooden piers should be used to jack up the front and rear axles of the locomotive, so that the tires will be lifted off the ground and will not bear the load, but must maintain appropriate air pressure.

        Third, if the new corn thresher is not in a free position when it is parked, the spring will lose its elasticity, causing plastic deformation and scrapping it in advance. For example, the intake and exhaust valves of the engine should be closed to prevent the spring from being compressed and prevent dust from entering the cylinder.

       We found that some robots never check or maintain certain parts. They always think that they will have no problems. As long as the parts are not damaged, they will continue to be used, and even there will be a dead-end for the maintenance and repair of agricultural machinery. Agricultural machinery is often prone to failure at critical times. For example, agricultural tools such as corn threshers have maintenance dead spots. Why does this happen? There are three main reasons.

       One is that some parts are in a state of hidden damage that is difficult to detect with the naked eye. This is the case for peeling rubber tubes. An agricultural vehicle emits black smoke and is unable to work. The inspection is caused by peeling of the inner layer of the intake pipe; and a wheeled tractor engine has too high water temperature and reduced power. The result proves that the inner wall of the radiator hose has fallen off and blocked the circulating water channel. . The cloth hose is stronger than the pure hose, because it is wound with multiple layers of cord in the hose. In the working process, due to the long-term bearing of circulating hot water or air flow, the thin rubber layer on the inner wall of the hose is easy to fall off, just like a movable valve, which makes the cross section of the pipe smaller and hinders the flow of circulating water or air. The above fault.

        Second, some failures of the automatic corn thresher are caused by the gradual failure of some parts over time. This is the case for the softening of the spring and the formation of scale in the cooling system. The softening of the springs, such as valve springs, governor springs, outlet valve springs, and clutch springs, will have a serious impact on the normal operation of the locomotive. Many operators believe that the cooling system scale has little effect on the engine's work, and the cleaning and maintenance work is more troublesome, so they don't care about it. However, after scale is generated in the cooling system, due to poor thermal conductivity, it is easy to cause overheating of the engine, resulting in a decline in power and economy.

       The third is to over-reliance on the manufacturing accuracy of the accessories, and therefore ignore the inspection before installation. Such as the side gap and back gap of the piston ring, if these gaps are too small, it is easy to cause the piston ring to jam or break....
