What is the maintenance rule of hydraulic system of lift platform
Today WIZ LIFT will tell you what are the maintenance items for the hydraulic system of the lift platform. The lift system is composed of hydraulic cylinders and hydraulic pump stations. It is vital to ensure the cleanliness of the hydraulic cylinders and hydraulic pump stations. For the hydraulic system of a hydraulic lift, the cleaning oil must use the same hydraulic oil as the system. The oil temperature is between 45 and 80°C. The lifting platform uses a large flow to remove impurities from the system as much as possible. The hydraulic system should be cleaned more than three times. After each cleaning, the oil will be drained from the system when it gets hot. After cleaning, clean the filter, replace with a new hydraulic lift and add new oil.
1. The hydraulic system of the hydraulic lift to prevent air from entering the hydraulic system.
Under normal pressure and normal temperature, the volume ratio of air contained in the hydraulic oil is 6% to 8%. When the pressure drops, the oil in the air will be released and the bubbles will burst, causing the hydraulic components to "cavitation" and generate noise. A large amount of air entering the oil will aggravate the "cavitation" phenomenon, increase the compressibility of the hydraulic oil, make the elevator run unstable, reduce work efficiency, and produce adverse effects such as "crawling" of the actuator. In addition, air also oxidizes hydraulic oil to accelerate oil degradation.
2. The following points can prevent air intrusion: 1. After repairing and replacing the oil of the hydraulic elevator, the air in the system should be cleared according to the random "Instruction Manual" to make it operate normally.
3. The suction pipe of the hydraulic oil pump of the hydraulic lift must not be exposed to the oil surface, and the suction pipe must be well sealed.
4. The seal of the oil pump drive shaft of the hydraulic elevator should be good. To Second, prevent water from intruding into the hydraulic system: In the hydraulic system of a freight elevator, excessive moisture in the oil will cause corrosion of hydraulic components, oil emulsification, decrease in lubricating oil film strength, and acceleration of mechanical wear.
In addition to preventing moisture intrusion during maintenance, it is also necessary to tighten the lid when the oil storage tank is not in use. It should be placed upside down; oil with high water content should be filtered several times. The filter paper should be replaced every time the hydraulic elevator filters. If there is no special instrument to detect, you can drop the oil on the hot iron plate without generating steam. Can be filled immediately after burning.
