Problems solved by technology
For example, oil cylinders working in front of steelmaking, steel rolling, non-ferrous metal smelting, metal material heat treatment furnaces, etc., although the oil cylinders are made of high-temperature resistant sealing materials, because the oil cylinders are under high temperature conditions of 250-400 °C, the seals of the oil cylinders will be damaged after working for 3-5 days. All are scrapped, and the service life is very short, causing the equipment to stop working and the factory to stop production
[0003] The working environment temperature of the oil cylinder is high, and the oil cylinder generates heat after working for a long time. Generally, the seals of the oil cylinder are mostly rubber products, and the maximum temperature resistance cannot exceed 200°C. If the temperature of the oil cylinder shell is too high, the high temperature aging of the seal will be caused. The use of the oil cylinder is limited, and the cooling water in the existing cooling oil cylinder is discharged directly after cooling, resulting in a waste of water resources, and it is impossible to quickly grasp the temperature of the oil cylinder when the oil cylinder is working

A self-circulation cooling type oil cylinder comprises an oil cylinder shell, a piston rod, a circulating cooling water tank and a circulating water pump, an oil cylinder cooling layer is arranged in the oil cylinder shell, a cooling water outlet is formed in the lower end of the left side of the oil cylinder shell, and the cooling water outlet is connected with a cooling water recycling water pipe. The cooling water recycling pipe is connected with a circulating water tank water inlet pipe, the circulating water tank water inlet pipe is connected to a circulating cooling water tank, a circulating water pump is arranged on the upper end face of the circulating cooling water tank and connected with a water outlet pipe, and the water outlet pipe is connected to a cooling water inlet formed in the upper end face of the oil cylinder shell. The oil cylinder cooling layer is provided with the cooling water inlet and the cooling water outlet, the heated cooling water enters the circulating cooling water tank through the cooling water outlet, and the cooling water enters the oil cylinder cooling layer through the cooling water inlet after being cooled in the circulating cooling water tank. And cyclic utilization of the cooling water is completed.
Description
technical field [0001] The invention relates to the field of cooling oil cylinders, in particular to a self-circulating cooling type oil cylinder. Background technique [0002] In the metallurgical smelting machinery and equipment industry, the working environment of most oil cylinders is under high temperature conditions. For example, oil cylinders working in front of steelmaking, steel rolling, non-ferrous metal smelting, metal material heat treatment furnaces, etc., although the oil cylinders are made of high-temperature resistant sealing materials, because the oil cylinders are under high temperature conditions of 250-400 ° C, the seals of the oil cylinders will be damaged after working for 3-5 days. All are scrapped, and the service life is very short, causing the equipment to stop working and the factory to stop production. [0003] The working environment temperature of the oil cylinder is high, and the oil cylinder generates heat after working for a long time. Gener...
