Hydraulic elevator drive chain system 液压升降机的传动链条系统
There are many types of hydraulic lifters. Common guideway lifters in the market are one kind. The power part of the lifter is hydraulic cylinder, but the transmission part is chain.
As the hydraulic elevator is a special equipment, so the use of the chain is very exquisite, jinan saili machinery co., ltd. is a professional manufacturer developing and manufacturing hydraulic lift, the selected elevator chain is custom-made professional.
A typical hydraulic elevator has a layer of oil on its chain. But that oil is not a lubricant, it is the oil that protects the chain, to take into account that the storage time of the chain may be longer, to avoid the rust and corrosion of the chain, so the oil above is not a lubricant. After the elevator chain has been used for a while, it needs to be oiled. The purpose of oiling is “too much of a good thing”.
The lifting chain must be oiled after a period of time. The oil can only be oiled on the chain. It is better to use motor oil and other mechanical oil.
All you have to do with the elevator chain is just keep some of the links between the chain joints, no more, just a little bit.
Inspection of hydraulic elevator chain:
1: whether the inner/outer chain sheet is deformed, cracked and corroded.
2: whether the pin is deformed or rotated, rusting.
3: the roller is cracked, broken and overworn
4. Whether the joint is loose and deformed
5. Sound or abnormal vibration during operation; good lubrication of the chain.
Chain is labor-intensive, and many developed countries have turned to developing countries for production, which brings new opportunities for China’s chain to expand export.
Chain manufacturing capability is the decisive factor of chain manufacturing, and the center of chain manufacturing strength is the degree of process of chain manufacturers. Chain manufacturing process depends largely on the professional level of chain consumption. The strength of process equipment directly influences the consumption efficiency, product quality and economic benefit of chain manufacturers. In recent years, the chain industry of our country is very attention to hardware devices, a lot of chain enterprises spend a lot of money and manpower and material resources, implementation of chain using electromechanical integration equipment modification and striking, successfully developed a high degree of strength of chain exclusive use manufacturing equipment, and put into use, its professional consumption efficiency, technological process more hasten is reasonable, function more complete, makes our country small and medium-sized chain manufacturers specifications power had a significant progress, especially the strict chain of hydraulic lift, manufacturing process is complicated, need to do all kinds of test, The strength and toughness of the body to achieve high requirements for the use of the lift chain.
