The speed ratio refers to the same flow (volume of liquid entering the hydraulic cylinder per unit time), Wuhan Hydraulic station manufactor The ratio of the piston rod extension speed to the retraction speed. The calculation is equal to the inverse ratio of the large cavity area and the small cavity area of the cylinder. The speed ratio is related to the cylinder diameter and rod diameter of the oil cylinder. Main products: harvesting machinery series Wuhan Hydraulic station Flip plow series, press series, grader series, TGL, HG, SG, DG series vehicle oil cylinder, HSG series engineering oil cylinder mining machinery, ship oil cylinder, and various non-standard oil cylinders. Welcome to order!

If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Wuhan Hydraulic station Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Wuhan Hydraulic station manufactor The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.

The diameter of the oil unloading hole of the hydraulic cylinder is too large, which directly affects the service life of the rubber seal ring on the piston. Because the piston moves back and forth, Wuhan Hydraulic station When the rubber seal ring on the piston passes through the oil discharge hole, the rubber's own elasticity expands to the oil discharge hole, and the oil discharge hole edge and the piston seal groove edge shear the rubber seal ring. At the same time, China has the advantages of strong market demand and low cost, and is expected to become the center of gravity of the world's hydraulic industry and oil cylinder industry in the future. The hydraulic cylinder is a very important part of the hydraulic machinery and plays an executive role in the entire hydraulic machinery, Wuhan Hydraulic station manufactor In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.

Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, Wuhan Hydraulic station And there is no transmission clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and pressure difference on both sides; The hydraulic cylinder basically consists of cylinder barrel, cylinder head Wuhan Hydraulic station manufactor The piston and piston rod, sealing device, buffer device and exhaust device are composed.
