With the development of society and the development of the elevator industry, hydraulic elevators have become an indispensable weapon for major production, manufacturing and processing industries. After the New Year, we all went to work as happily as before, but at work, many hydraulic equipment did not want to be as easy to use as before. At this time, the workers in the maintenance class in our factory went to work as a whole to repair. Does not affect production. The leaders of our company also wondered that many of them were new equipment purchased enough years ago, and they couldn't go wrong in such a short time, so they called the equipment manufacturers for repairs. Equipment manufacturers send workers to repair. Think about it the other way round and still don't know much about the device. For hydraulic equipment, it is not used for a period of time, and it must be idling for a period of time when the weather is cold in winter. For example, hydraulic lifts. Take hydraulic lifts for example. In coastal cities that are relatively cold in winter, if the equipment is not used for a period of time, the hydraulic oil of the equipment will settle. If it is not suitable for a long time, the hydraulic oil is not very thin. It is for these reasons that our equipment is not operating at the normal speed. Leaders of the company should not worry, it is not difficult to solve this problem. The equipment will run a few more times, and the effect will be more obvious. Like in the northern part, if you buy some kerosene and add it, the effect will be better. But remember to use summer hydraulic oil in summer.
