Summer is coming, in the summer excavator maintenance management is very important, routine maintenance excavator is mainly reflected in several aspects of it? First, the excavator routine maintenance: all grease fittings, slewing ring, wiping every 10 Sky 15 days once the butter, different angles butter every 4-8 hours to play twice, each gear within the first 520 hours of work to replace one, After the replacement of 2-3 times a year, the engine must be preheated for 10-15 minutes before work. Second, the hydraulic oil in winter and summer two winter oil is 32 or 46, 68 or 100 summer oil, hydraulic oils must, Used Mini excavator price, the difference is high summer temperatures, 90 digging machine prices , the use of hydraulic oil viscosity is high, low winter temperatures, the use of hydraulic oil viscosity is low. Third, the excavator which is easy to loose parts A: slewing ring gear, the engine loose screws, requirements and coated plastic thread, must bear firmly. IV Notes A parking after: low-speed operation must be 10-15 minutes before the flame, a first arm and bucket perpendicular to the ground, the pilot activity several times, and the hydraulic oil pressure in the system all the relief so far. Fifth, within the structure of Rotary reducer A: rotary motor, motor bracket, a shaft drive, a Samsung frame, a shaft, Samsung hoist, drive ring, vertical. Sixth, the running gear of the internal structure of the A: travel motor, a gear, ring gear, the Samsung stand, Samsung hoist, gear holder, axle, wheels ring. Excavator Excavator prevent air and water intrusion hydraulic system, the hydraulic system to prevent air intrusion containing volume ratio of 6 to 8% air at atmospheric pressure at room temperature hydraulic oil, reduce air when the pressure will be freed from the oil bubble rupture of the hydraulic components "cavitation" noise. A lot of air into the oil will "cavitation" phenomenon intensified, hydraulic oil compression increases, job insecurity, digging machine prices, reduced efficiency, the actuator appears to work "crawl" and other adverse consequences. In addition, the air will make the hydraulic oil oxidation, accelerate the deterioration of oil. Prevent air intrusion should note the following: (1), after repairs and oil changes according to the random "manual" for excluding the air system to normal operation. (2) hydraulic pump suction nozzle shall not expose the oil, the suction line must be sealed well. (3), the oil pump drive shaft seal should be good, pay attention to where the seals should be used to replace the "lips" Authentic Seal, can not use the "single lip" seal in place, because the "single lip" seal oil seal in only one direction, It does not have the function of sealing gas. Had an overhaul after Liugong ZL50 loaders, hydraulic pump consecutive "cavitation" noise, fuel tank level automatically rises failure, hydraulic pump repair process upon inquiry, we found that the hydraulic pump drive shaft seal is the misuse of the "single lip "seal due. 2, to prevent water intrusion hydraulic system oil contains excessive moisture, Xuchang digging machine price, make hydraulic components rust, oil emulsion deterioration, reduced lubricant film strength, accelerated mechanical wear. In addition to maintenance to prevent moisture invasion, but also pay attention to oil tank when not in use, tighten the lid, preferably upside down; high water content of the oil through several filters, each one at a time to replace a dry filter paper, In the absence of special detection equipment can be droplets on a hot iron plate, no steam can only fill out and immediately burn.泰安嘉 and Heavy Machinery Co., a small digging machine prices, Kerry and Heavy Industries (online consultation), Xuchang digging machine prices offered by 泰安嘉 and Heavy Machinery Co., Ltd ..
