Problems solved by technology
[0002] At present, in the field of axially reciprocating axially moving hydraulic cylinders (including hydraulic cylinders, pneumatic cylinders, hydraulic cylinders, etc.), it is often necessary to expose the piston rod of the hydraulic cylinder to dust, smoke, mist, steam and Under harsh working environments such as gas, humidity, acid-base, heat, and severe cold, dust, smoke, water vapor, and acid-base components in the environment enter the cylinder barrel of the hydraulic cylinder with the expansion and contraction of the hydraulic cylinder, contaminating the hydraulic fluid ( Oil pressure, air pressure, water pressure and other fluids), and when the hydraulic cylinder is working, the temperature of the hydraulic fluid will change drastically, which will affect the physical and chemical properties of the hydraulic fluid (such as viscosity characteristics, etc.), these combined effects will weaken the hydraulic cylinder. The performance will affect the working efficiency and quality of the hydraulic cylinder, and even cause the hydraulic cylinder to fail.

Embodiment Construction
[0025] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.
[0026] combine Figure 1 to Figure 4 As shown, a device for dust prevention and heat control of a hydraulic cylinder, including a fixed sleeve, an annular fan mechanism, a sealing end cover, and a dust cover; sports. The fixed sleeve is set on the outer peripheral wall of the cylinder barrel of the hydraulic cylinder, and the annular fan mechanism is set on the fixed sleeve. The cylinder barrel, the fixed sleeve, and the annular fan mechanism are in a fixed relationship with each other. The sealing end cover is arranged on the end of the cylinder, that is, the sealing end cover is arranged on the open end of the cylinder ( figure 2 The lower end of the middle cylinder), the sealing end cover is used to seal the cylinder to prevent the hydraulic fluid (oil pressure, air pressure, water pressure and other fluids) in the cylinder from leaki...
