In life, the hydraulic jack is a very common tool, but in daily use, the jack will be damaged due to improper use! Hydraulic jacks can obtain pressure through liquid to achieve the purpose of variable force! So what causes hydraulic jack damage?
1. The sealing quality is not good. The structural design of the seal is unreasonable, the materials are not good, the manufacturing process and precision are poor, the mold is defective, and the trimming is defective, resulting in damage to the hydraulic jack.
2. Reasons for storage, transportation and maintenance. Damage to hydraulic jacks can result from improper storage overflows and moisture, oxygen and ozone attack, improper stacking conditions, and improper maintenance.
3. Poor parts manufacturing and assembly quality. The processing accuracy and surface roughness of the accessories do not meet the requirements, and the processing methods are unreasonable. Hydraulic jacks are damaged due to unprotected lip damage when the seal passes through sharp edges and the top of the threads during installation.
4. The design and structure of the accessories are unreasonable. The selected seal cannot meet the requirements of working pressure, speed and temperature, and is incompatible with the oil medium and environmental conditions. Improper design of the groove of the installed seal, unreasonable selection of clearance and compression, and failure to pay attention to anti-corrosion, anti-vibration, pressure equalization, etc. are all unreasonable design and structure of the mating parts, resulting in damage to the hydraulic jack during use.
