Problems solved by technology
In the case of low temperature, the viscosity of the hydraulic oil is high and the fluidity is poor, which leads to the slow movement of the hydraulic cylinder and the unsmooth start of the hydraulic cylinder.
The hydraulic oil enters the hydraulic cylinder through the oil pump, and there is a temperature difference between the hydraulic oil and the hydraulic cylinder. When the temperature difference is large, the inner wall of the cylinder and the piston and other parts will bear this temperature difference, which will affect the performance of the material, and eventually will Reduced service life of hydraulic cylinders

The invention provides a hydraulic oil temperature keeping device of a hydraulic cylinder. The hydraulic oil temperature keeping device of the hydraulic cylinder comprises a connecting pipe, a temperature control pipe and a control system, wherein the temperature control pipe is inserted in the connecting pipe; and heating pipes are arranged in the temperature control pipe. The control system comprises a temperature sensor arranged in the connecting pipe, and a processor arranged outside the connecting pipe; the temperature sensor and the processor are electrically connected; and the processor and the heating pipes are electrically connected. The hydraulic oil temperature keeping device of the hydraulic cylinder can keep the temperature of hydraulic oil entering the hydraulic cylinder to prevent unsmooth starting of the hydraulic cylinder caused by too low temperature from and to prevent damage to parts of the hydraulic cylinder caused by too low temperature of the hydraulic cylinder, so that the maintenance cost of the hydraulic cylinder is reduced, and the service life of the hydraulic cylinder is prolonged.
Description
technical field [0001] The invention relates to the technical field of hydraulic cylinder protection, in particular to a hydraulic oil heat preservation device for a hydraulic cylinder. Background technique [0002] Hydraulic cylinder is a widely used hydraulic actuator. Hydraulic cylinders convert the pressure energy of hydraulic oil into mechanical energy. The hydraulic cylinder has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable. Hydraulic cylinders are used in various environments due to their excellent performance. In the case of low temperature, the viscosity of the hydraulic oil is high and the fluidity is poor, which leads to the slow movement of the hydraulic cylinder and the unsmooth start of the hydraulic cylinder. The hydraulic oil enters the hydraulic cylinder through the oil pump, and there is a temperature differenc...
