The principle of the hydraulic rod is to fill a closed pressure cylinder with damping grease to make the pressure in the cavity several or tens of times higher than the atmospheric pressure. The pressure difference generated by the cross-sectional area of the piston rod is smaller than that of the piston. Realize the movement of the piston rod. The hydraulic support rod is an industrial accessory that can support, buffer, brake, height adjustment and angle adjustment. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (damping grease), control elements in the cylinder and control elements outside the cylinder (referring to controllable gas springs) and joints.
General specifications of hydraulic rods: According to different places of use, there are many specifications of hydraulic rods. It is used on train seats, aircraft racks, medical beds, patient tables, tool boxes and fish tanks. Damping force and damping speed can be customized according to requirements. The minimum damping force is 10N, and the maximum damping force can reach 1500N. The diameter and connection method can be customized.
The hydraulic rod is an elastic element with gas and liquid as the working medium. It is composed of a pressure tube, a piston, a piston rod and a number of connecting parts. The inside is filled with high-pressure nitrogen. Because there are through holes inside the piston, there is gas at both ends of the piston. The pressure is equal, but the cross-sectional area on both sides of the piston is different. One end is connected to the piston rod and the other end is not. Under the action of gas pressure, pressure is generated to the side of the smaller cross-sectional area, that is, the elastic force of the support rod. The elastic force can be passed Set different nitrogen pressures or piston rods of different diameters. Unlike mechanical springs, the support rod has a nearly linear elastic curve. The elastic coefficient of the standard support rod is between 1.2 and 1.4, and other parameters can be flexibly defined according to requirements and working conditions.
Pain points of choosing fat:
1. The type of damping grease is relatively single and cannot cope with various damping strengths;
2. The damping force is unstable under low temperature conditions;
3. Insufficient sealing and waterproof performance.
