In operation, the temperature of each component has its own normal range double roll crusher. Such as general cooling water temperature is 80 ~ 90 ℃, the temperature of the hydraulic drive system of hydraulic oil is 30 ~ 60 ℃, below or exceed this range will accelerate the wear and tear of parts, causing deterioration of lubricating oil, resulting in changes in material properties and so on. Tests showed price excavators, engineering machinery main drive gear and bearing lubricants operate at -5 ℃ than the operation of the lubricating oil 3 ℃, the wear and tear to be increased from 10 to 12 times the Breakers. But when the temperature is too high, will accelerate the deterioration of lubricating oil, such as oil temperature checked 55 ~ 60 ℃, the oil temperature is increased by 5 ℃, the oxidation rate of the oil will be doubled. To this end, the engineering machinery in use, one to prevent overload conducted at low temperatures, to ensure the normal operation of the low-speed pre-heating phase, the mechanical reach the required temperature before traveling or working, not because there was not a problem while ignoring its important to do; two to prevent mechanical operation at high temperatures, mechanical during operation should always check the value of various thermometers, identify problems immediately stop inspection, found fault even excluding roll break. We could not find a reason for the small excavator price list, must not fail treated and still make mechanical work sick. In the usual work, pay attention to check the working conditions of the cooling system of composite crusher. For water-cooled machine, must be checked daily before work, and refresh the cooling water; for air-cooled machines, also regularly clean up the dust on the air cooling system to ensure the smooth flow of cooling air duct. Mechanized construction companies, engineering machinery technical condition is good or not is a direct factor in business whether normal production. On hydraulic transmission engineering machinery, the normal operation of the hydraulic system is a major sign of their good technical condition. Qualified hydraulic oil is to protect the hydraulic system and reliable operation of mini excavators prices, proper maintenance is essential for reliable operation of the hydraulic system. To this end, according to the work they practice on safeguarding the general operating environment of a hydraulic system for rough discussed. Select the appropriate hydraulic oil hydraulic oil in the hydraulic system plays a transmit pressure, lubrication, cooling, sealing effect, the inappropriate choice of hydraulic fluid is a hydraulic system failure and durability early decline. When selecting hydraulic oil grade should be random "manual" in the provisions of the special circumstances need to substitute oil, we should seek the same performance as its original performance grades. Different brands of hydraulic oil can not be mixed use, to prevent hydraulic oil to produce a chemical reaction, the performance changes. Dark brown, white, smelly oil hydraulic oil is bad, you can not use. Baoding excavator price, Kerry and heavy industry, domestic small excavator price offered by 泰安嘉 and Heavy Machinery Co., Ltd ..
