How the hydraulic lifting platform maintenance and repair?

For hydraulic mechanical lifting devices, machinery normal running well or not is directly related to the enterprise whether the normal factors of production. On hydraulic lifting equipment, normal operation of the hydraulic system is a major sign of good technical condition.
And qualified hydraulic oil is to protect the reliable operation of the hydraulic system, proper maintenance of the hydraulic system can not only reduce repair and maintenance costs, but also to create greater value for the enterprise long-term use. How lifting platform for systematic maintenance and maintained?
Select a suitable hydraulic oil
Hydraulic oil plays a delivery pressure in the hydraulic system, lubrication, cooling and sealing effect, an inappropriate choice of hydraulic oil is a hydraulic system failure and durability of early decline. When grade hydraulic oil should randomly select "Manual" specified in special circumstances require the use of substitute oil, should seek their grades the same performance as the original performance. Different grades of hydraulic oil can not be mixed with the hydraulic oil to prevent a chemical reaction, the performance change. Dark brown, white, smelly oil hydraulic oil is deterioration can not be used.
Prevent contamination of the hydraulic system solid
Clean hydraulic oil is the life of the hydraulic system. Hydraulic system has many precision coupling, and some damping holes, some have gaps and so on. If solid impurities precision coupling invasion will cause strain, credit card issuers, oil duct blockage, endangering the safe operation of the hydraulic system. Ways general solid impurities invade the hydraulic system are: hydraulic oil unclean; refueling tool unclean; refuel and repair and maintenance accidentally; scaling and other hydraulic components. Solid impurities can prevent intrusion system from the following aspects:
When refueling
Fill the hydraulic oil must be filtered, clean and reliable tool should refuel. Not in order to improve the speed and remove the fuel tank fuel filter at the mouth. Refueling should use clean gloves and coveralls to prevent solids and fibrous impurities fall into the oil.
Maintenance time
Removing the hydraulic tank filler cap, filter cover, detecting holes, hydraulic tubing and other parts, causing the system to avoid dust exposure oil channel, after the demolition of the site must first be thoroughly cleaned to open. When the hydraulic tank filler cap as demolition, first remove the soil around the tank cover, rear twist pine oil cover, remove the debris left in the joint zone (not rinsed with water to prevent water infiltration tank), confirmed to clean the fuel tank cap can be opened. For use when wiping material and hammer, can not afford to wipe material should be selected and the striking face fiber impurities attached special rubber hammer. Hydraulic components, hydraulic hose should carefully cleaned with high pressure blown dry after assembly. Selection of genuine packaging intact filter (within the packaging is damaged, although the filter in good condition, it may unclean). Meanwhile wash the filter oil change, the application materials carefully wipe clean the dirt at the bottom of the filter housing before installing the filter.
Cleaning the hydraulic system
Cleaning the oil used in the system must use the same grade of hydraulic oil, the oil temperature between 45 ~ 80 ℃, with a large flow rate in the system as impurities away. Hydraulic system to repeatedly wash more than three times, after each cleaning, the entire release system to take advantage of the oil is hot. Cleaning is completed and then cleaning the filter, add new oil after replacing the new filter.
