It's getting colder and colder. Recently, many users have come to consult us. What are the tips for maintaining hydraulic freight elevators in winter? The following are the technical staff of the hydraulic lifting freight elevator manufacturers to introduce to you:
The first reason is also the main reason. Many workers in other industries are unaware that the hydraulic oil used in hydraulic lifts is different in summer and winter. At low temperatures, hydraulic oils used in the summer can become sticky and even freeze. After entering low temperature in winter, you must remember to change the hydraulic oil containing antifreeze in winter, this oil is suitable for low temperature operation.
The second is that steel has a significant thermal expansion and contraction effect at low temperatures. Although steel is considered when designing and manufacturing hydraulic lift freight elevators, the environment is different after all. Under extremely low temperature conditions, the steel will have some unstable properties, such as increased hardness and reduced toughness. At this time, we need to pay more attention to the maintenance of the equipment to make the key parts lubricate.
Third, the hydraulic lift freight elevator maintenance tips:
1. When the equipment is used for about 2 months (according to the actual frequency of use), it is necessary to add lubricating oil to the rotating part.
2. Regularly check the working status of the hydraulic lifting freight elevator pin every month. If the pins and screws are loose, they must be tightened to prevent the pins and screws from falling off and causing accidents
3.Hydraulic oil should be kept clean and replaced every 6 months
4, when maintaining and cleaning the hydraulic lift, ensure that the support is safe
The technical personnel of the hydraulic freight elevator manufacturer will introduce the winter maintenance and maintenance skills of the hydraulic lifting freight elevator to everyone, and I hope to help you better in winter.
