Through cooperation of a U-shaped backflow tube and devices on the U-shaped backflow tube, cooling liquid circulates in the U-shaped backflow tube, heat exchange is conducted between the cooling liquid and hydraulic oil in the hydraulic oil cylinder, and the cooling liquid can take away heat generated when the hydraulic oil cylinder operates, so that the hydraulic oil in the hydraulic oil cylinder can be cooled, cylinder explosion caused by too high temperature is prevented, and the purpose of effectively cooling is achieved.

Description

technical field [0001] The invention relates to the field of hydraulic oil cylinders, in particular to a temperature-drop type explosion-proof early warning hydraulic oil cylinder. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. The power source of the hydraulic cylinder is the thrust of hydraulic oil. There is no deceleration device, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. [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.

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
