See how the summer to your excavator 'sunscreen hydrating'

Recent excavator attachments many times to share summer excavator maintenance. Hot weather in summer we must attach importance to excavator maintenance. Outbreak, resume work delay, at this stage is to compare the busy period of engineering. Must reduce excavator failure and ensure the construction period. Next summer in excavator maintenance methods: first, before entering the summer, to targeted on every excavator parts of the lubrication system can make a one-off detection, in order to make the oil pressure gauge, transmission pressure gauge instructions accurately. For gearbox, variable pitch and drive axle oil in a system of inspection, from the quality of the oil to the amount of oil, and to keep the oil clean.

2, in order to ensure that the cooling system of the machine performance is good, before entering the summer, the cooling system of the excavator accessories tighten and thorough cleaning, lubrication, cleaning as possible cooling system scale ( Including the scale clean radiators) To increase the cooling efficiency, keep clear of the cooling system and accelerated cooling water circulation. 3, check the connection hose, water tank of the oil resistance of the rubber hose is poorer, easy to early damage, thus affect the water supply, causes the engine temperature is too high. Check have burst and leakage phenomenon, to rule out in a timely manner. At the same time to keep enough water, found insufficient to add in a timely manner. Four, in order to ensure the correct use of the machine, are aware of water thermometer readings, & 90 deg; When the above measures must be taken. Can choose the nearest parking the shade and cool in idle speed, be careful not to shut down immediately, in order to prevent the engine internal cylinder caused overheating accident, etc. After being temperature drop down, but should also check the fan belt tension.

5, to ensure that the battery electrolyte level; High summer temperatures, evaporation, liquid level height falling fast, should be timely supplement of distilled water or electrolyte according to need, Pay attention to its purity) Above the plate at the top of the liquid level height 10 a 15 mm, avoid to produce plate oxidation. Should clean up the dirt on the surface of the battery in time, and the pile and the oxide on the wire connection, vent should be keep smooth, clean, battery should be fixed. In a timely manner to eliminate battery failure, do maintenance on time, timely maintenance. Six, check the braking performance of the machine, so that early detection and exclude the failure of the braking system, to reduce accidents. Homework for braking for a long period of time, make the temperature of the brake hub and brake piece is too high, braking performance degradation, should immediately stop the cooling, so as not to bring the machine operation safety hidden trouble. But not allow to forced cooling with cold water poured brake.

7, the machine if in case of wading, so after wading disc Zha actuator, the water should maintain a lower speed, the use of shoe and the brake hub of friction heat drying shoe, to avoid brake block. Eight, the transmission system of lubrication and transmission mechanism of the machine under high temperature excavator attachments wear and tear, largely mainly depends on the lubricating oil quality, adopted by the long-term experiment proved that using larger touch of lubricating oil, can make the transmission system to reduce wear and tear. Application of high dropping point of lubricating oil, especially be careful not to let the water and air into the hydraulic system, hydraulic system changes, has led to the wear and corrosion phenomenon of system. 【 Mechanical 】 Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent the views or responsibility for their authenticity.
