How to maintain the crusher in winter
With the crusher in the stone crusher on the basis of the continuous enhancement of the development of the product performance is also improving, to a greater extent to meet the requirements of users, but also to a certain extent to improve the overall process of the mining industry. That crusher in the improvement process, high or low temperatures will certainly have a certain impact on it, how to solve this problem? Jaw crusher, impact crusher, cone crusher, impact crusher, etc., to enable them to be able to -50 degrees Celsius below can still work without load.
As the temperature is relatively low in winter, it will not only greatly reduce the service life of the crusher, it is easier to make the oil and water in the crusher is frozen, so in the winter before the best crusher to do a thorough inspection, maintenance, to ensure that the construction machinery safety over the winter, so as to avoid problems with the machine at that time on the production impact. That in the winter maintenance crusher considerations are as follows:
1. Crusher cleaning
Cleaning construction machinery diesel engine, chassis, the appearance of the working device can play a role in removing dirt, in the cleaning process can also be found in the various devices, parts damaged and leaking oil parts, for the next step of maintenance to do a good job in advance. It is strictly prohibited to use high-pressure and high-temperature water gun to flush the parts with high waterproof requirements, especially the electrical parts, so as not to cause damage.
2. Selection and replacement of oil
a. Selection of fuel oil. Diesel fuel is easy to wax at low temperatures, viscosity increases, mobility deteriorates, poor atomization, so that the combustion process deteriorates, reducing the power and economy of the diesel engine. In order to make the diesel engine work softly, reduce fuel consumption, should use the lower condensation point of diesel fuel.
b. Diesel engine oil replacement. Diesel engine should be selected with a smaller viscosity of low-temperature oil. Try to use high-performance oil, this kind of oil is not only not easy to oxidize at high temperatures, and will not leave deposits in the precision parts of the diesel engine, can greatly extend the life of the diesel engine. Replacement of oil at the same time, should replace or clean the oil filter.
c. Replacement of lubricating oil and grease. Seasonal maintenance, the transmission, splitter, differential, steering gear oil in the gear oil into the winter gear oil, oil change, pay attention to cleaning.
3. Maintenance of parts and components
a. Diesel engine cooling system sand production line maintenance check the thermostat working condition, to prevent the diesel engine water temperature is too low or too high. Remove the scale in the water jacket. To choose a lower than the lowest temperature in the region where the construction machinery is used about 10 ℃, and have winter anti-freezing, summer anti-boiling, anti-corrosion, waterproof scale of the long-lasting antifreeze. Once the water tank is found to have mud and sand siltation, remove it immediately.
b. Maintenance of electrical equipment check the battery motor wiring. Check and adjust the electrolyte density. Maintain the starter motor, adjust the generator charging voltage. In winter, you should often charge the battery and maintain the preheating device.
c. Maintenance of the braking system pay attention to whether the brake fluid is sufficient, whether the quality of broken deterioration. Check whether the oil-water separator and the pollution release switch work normally. Check whether the brake has become weak, run off, the brake pedal pedal force is insufficient and the brake does not return to the phenomenon, timely adjustment.
