Do you know how to maintain the hydraulic lifting platform daily?

点击浏览: Release time: 2019-07-18Click to browse: Source: Longzhu Machinery- Lift Freight Lift Manufacturer

The hydraulic lifting platform has been inspected and debugged before leaving the factory, and the various technical indicators have met the design requirements. Only the power supply needs to be connected when using. However, daily maintenance before work is also very important, and it also relates to personnel safety and equipment life. The following introduces the daily maintenance of the hydraulic lifting platform for everyone, I hope to help you.

⒈ Monthly maintenance

During maintenance of the hydraulic lifting platform, personnel enter the lifting platform to work, and the elevator must be suspended to prevent the lifting platform from falling suddenly and causing casualties.

A. Check the lubrication and wear of rollers, intermediate shafts and bearings; cylinder pins and bearings; boom hinges and bearings

B. Fill the above parts with lubricating oil. Extend bearing life.

C. Check hydraulic oil quality and oil level. When the lifting platform is raised to the highest level, the hydraulic oil level should be 40-50 mm above the bottom of the fuel tank. When the oil color of the hydraulic oil becomes dark, the oil is sticky, or there is foreign matter such as grit in the oil, the hydraulic oil should be replaced in time. The hydraulic system of the lifting platform uses 32 # hydraulic oil.

⒉year-end maintenance

A. Check hydraulic and piping connections. If the pipe is damaged, it should be replaced immediately; tighten the pipe joint when the connection part is loose.

B. Remove and disassemble the lowering valve, blow the valve core with compressed air and install it again.

C. Fully drain all the hydraulic oil in the fuel tank, open the fuel tank, remove the suction filter, wash it and put it back into the fuel tank, and install it in place. The fuel tank is refilled with new oil.

你知道液压升降平台的日常怎么维护吗?

Lift cannot lift or weak lifting force

⒈Relief valve pressure adjustment does not meet the requirements to adjust the pressure to the required value

检查 Cylinder internal leakage check or replace the cylinder assembly

⒊ Reversing valve is clamped or leaked Check or replace valve assembly

⒋The oil level is too low, the oil inlet filter is clogged, add enough oil, and clean the oil filter

⒌Check the fuel supply pump or replace the pump

Ripper cannot lift or weak

⒈Relief valve pressure adjustment does not meet the requirements to adjust the pressure to the required value

泄 Refer to the method of 2.3.4.5 above for leakage in the oil cylinder

⒊ Reversing valve is stuck or leaking

⒋The oil level is too low and the oil inlet filter is blocked

毛 Defective fuel pump

泄漏 Check valve leakage Check the damage of check valve core and valve seat, check the check valve spring for fatigue, deformation, etc.

Heavy lever

⒈The operating lever mechanism has fault inspection, adjustment and replacement of unqualified parts; cleaning of valve parts; check of hydraulic oil cleanliness

⒉Control valve spool is clamped (manufacturing, installation problems, dirt problems)

Torque converter and faults, such as weak torque converter, power shift failure, high oil temperature, etc.

⒈Weak torque converter

不足 Insufficient amount of hydraulic oil

压 Improper voltage regulation

⑶ Insufficient back pressure Check the torque converter oil quality (whether the hydraulic transmission oil is used by mistake), the amount of use, and check the torque converter pressure regulator, back pressure valve and its adjusted pressure value

⒉Power shift failure

⑴.Quick check valve, pressure reducing valve, power transmission valve, directional valve are stuck and leaking

⑵. Oil pollution is serious. Check the cause of valve jam and eliminate it accordingly. Filter or replace the hydraulic oil.
