During the high temperature in the summer of the three seasons, the harvester is prone to water boiling and overheating of the engine, which makes it difficult for the machine to work normally, which affects the production efficiency. The reasons and remedies are as follows: 1. The radiator is not well maintained. During the working process of the harvester, the air passage in the lower part of the radiator is easy to produce blockages, and the radiator must be constantly maintained. However, in some places, there is a lack of air pump and water gun equipment, and the operators often neglect the work in this area. With the increase of time, the cooling surface will become more and more serious and even lose heat. Remedy: Remove the blockage on the air channel between the heat sinks in time. In general, compressed air can be used for cleaning. When it is difficult, it can be washed with a water gun and combined with a thin wire to clear it. However, the radiator must be dry before it can be put into use. Second, the overload operation harvester in a long time operation, the power consumption is too large, easy to cause the engine speed down, the fan speed is reduced, the lack of air volume, causing the engine to overheat. Exclusion method: Try to work in a dry field as soon as possible, and adjust the forward gear, cutting width, and cutting height of the harvester in time according to crop yield, height, and maturity. Minimize long-term overload operations. Third, the water tank is not covered by the lid causing the cooling core to block; plug a lot of operators like to let the tank open to work: to open the engine cover when the water temperature is too high can add water. In this way, the crop leaves and dust easily enter the interior of the tank, with the cooling water to reach the body and cylinder head and gradually deposited, affecting the heat, in serious cases will also cause the cooling core block, resulting in engine overheating. Remedy: In order to save the cooling and unloading time required for adding cooling water, the tank can be sealed with multi-layer gauze and fixed with lead wire to prevent crops and dust from entering the tank. Fourth, the cooling water addition method does not add cooling water to some operators often wet the heat sink, even worse, the excess cooling water is poured to the radiator. Doing so will promote the dust to adhere more easily and cause blockage and reduce the heat dissipation effect. Remedy: Do not wet the radiator when adding water, but do not splash it. The operator should correct this incorrect operation method.
Red Star Apple
Red Star apple variety originated in the United States and was introduced to Qingdao in 1982. It is mainly distributed in Jiaonan, Laixi, Pingdu, and Jimo. It is one of the main apple varieties grown in Qingdao. The average weight of a single Red Star apple is 190 grams, with some reaching up to 500 grams, and the fruit shape index is around 1, with a conical shape. The fruit surface is smooth, with thick wax, abundant bloom, deep and wide calyx cavity, and prominent five ridges. When the fruit first turns red, there are distinct intermittent red stripes, followed by a red blush, and when fully colored, the whole fruit is deep red with prominent purple-red coarse stripes, a glossy surface, and light brown or gray-white fruit dots. The flesh is pale yellow, crisp, juicy, and sweet.
