Problems solved by technology

[0003] The hydraulic cylinder can provide high-frequency and large thrust. During the working process of the hydraulic cylinder, there is friction between the hydraulic oil and the cylinder wall. At the same time, the friction between the hydraulic oil and the cylinder wall will generate a lot of heat. At the same time, under the condition of heavy load, the hydraulic oil will be compressed to a certain extent, and the viscosity coefficient of the hydraulic oil will also increase accordingly. The friction generated during work will If it is further increased, a large amount of heat will be generated. If the heat is dissipated only through the thermal conductivity of the hydraulic cylinder itself, it will be difficult to dissipate the heat quickly, and if the staff does not find the abnormality in time, the hydraulic cylinder will continue to operate. Cylinder explosion is prone to occur when working under high temperature
[0004] How to design a temperature-dropping explosion-proof early warning hydraulic cylinder that can efficiently cool down, effectively avoid the occurrence of cylinder explosion, and can issue an alarm at high temperature has become a solution to the existing technology that generates a lot of heat during high-frequency operation or under load. , There is a high risk of cylinder explosion, and it is difficult for staff to find abnormal problems in time
