Before the cold weather, how to maintain the machinery?
1、 Clean the exterior
During the construction of cold regenerator, a large amount of dust will fall on the surface of the regenerator, including oil stains and other pollutants in the construction, which has little influence on the appearance, and more seriously, it becomes the inducing factor of corrosion.
1. Clean the appearance of diesel engine, chassis and working device of construction machinery, remove dirt and oil, and keep the appearance of regenerator clean.
2. It is forbidden to use high-pressure and high-temperature water gun to wash the parts with high waterproof requirements (especially the electrical parts), so as to avoid damage to the electrical parts.
Cleaning appearance is one of the key points of winter maintenance of construction machinery.
2、 Maintain the rotor and its casing and slippers
1. Check whether there is cement scaling on the rotor, clean up the dust in time, and replace the cutting tools that need to be cut and welded in time;
2. Clean the dust on the rotor housing, and pad the rotor housing 5-10 cm above the ground to prevent the erosion of rain and snow at the end of construction;
3. Check the slipper, repair the worn part of the slipper, and apply grease on the thread to prevent rust.
3、 Replacement method of gear oil for reducer
1. Site: it is required to harden the road surface without dust. The area should be about 200 square meters. It should be a warehouse as far as possible, but there should be enough working height and radius of 25 tons of crane.
2. Facilities: a 25 ton crane (20 tons is OK).
3、配件：进口美孚齿轮油9升、卫生纸10卷、塑料带20个、废油桶2个、紧固胶262/340一支、密封胶587一支、黄油一袋，细线绳20米、 12 *45的带母螺栓30套、4*30开口销10个。
3. Accessories: imported Mobil gear oil 9L, 10 rolls of toilet paper, 20 plastic belts, 2 waste oil drums, a 262 / 340 fastening glue, 587 sealant, a bag of butter, 20 meters of string, 30 sets of 12 * 45 female bolts and 10 4 * 30 split pins.
4. Tools: at least one set of 10, 16, 18, 19, 21, 22, 24, 30 sockets and spanners, one quick wrench and one long and short extension rod, one afterburner, 30 tire wrench, 10 mm hexagon wrench, two 55 adjustable spanners, one small loose end wrench, one small vice, one hand vice, one slotted screwdriver, one hammer head and two crowbars Pneumatic wrench and air pump can improve work efficiency.
(inspection of reducer oil level and reducer oil: cut off the power supply, wait for the reducer to cool down, open the oil drain plug, check whether the oil is full to avoid oil leakage, take oil sample, check oil color and viscosity index, if the oil is obviously turbid, it is recommended to replace it as soon as possible. After the new reducer is used for (500-1000) hours, the new oil shall be replaced (the internal dirty oil shall be flushed out), and then the oil shall be replaced every 1500 hours. However, the quality of the oil still needs to be checked during the use, and the oil shall be replaced at any time in case of aging and deterioration.)
