Nuclear power quick-cutting series servo hydraulic cylinder

The product has the advantages of fast response, sensitivity, high precision and reliable performance, and integrates high-precision proportional valve. The hydraulic actuator of quick-cut valve is a hydraulic control device designed and developed for the TRT quick-cut valve of nuclear power system. Its main structure consists of: 1. Control valve group: by the pressure reducing valve, hydraulic control check valve, solenoid valve and cartridge valve, see the system schematic diagram. 2. Quick cylinder: composed of special cylinder and spring. 3. Transmission box: composed of box body, shift fork and transmission rod. The hydraulic control system composed of the above components realizes the slow opening, slow closing, fast closing and swimming of the fast cutting valve through the power provided by the power source of the main system.

AGC automatic thickness control series servo hydraulic cylinder

AGC cylinder is a high-end servo hydraulic cylinder for adjusting roll gap on metallurgical rolling mill. It has the characteristics of high response frequency, low friction and short stroke. Common specifications: cylinder diameter 600-2000mm, rod diameter 450-1600mm, stroke 50-800mm; Hydraulic automatic thickness control, referred to as hydraulic AGC or HAGC, is called hydraulic pressure up system in China and HAGC is also called HGC in foreign countries. It is an important part of the rolling mill and one of the key technologies for the precise control of the thickness of modern strip. The HAGC system controls the displacement of the hydraulic cylinder through the electro-hydraulic servo valve to make the roll move up and down to complete the roll gap.

Piling machinery series Hydraulic cylinder

The main products are static pile pressing machine, rotary digging machine and other full set of hydraulic cylinder, such as luffing cylinder, mast cylinder, pressure cylinder and so on. The cylinder body is made of high-strength alloy steel, the piston rod is made of high-strength carbon steel, and is based on the design concept of improving the strength of the rod body and high-performance heat treatment. It has a high safety factor and can withstand high working pressure and tension. Good safety performance. The surface of the piston rod adopts the intermediate frequency quenching process, and the surface hardness, wear resistance and smoothness are effectively improved after the working surface is plated with chromium, so that the surface of the piston rod has high pressure resistance and corrosion resistance. Adopt advanced sealing technology to ensure smooth operation of the oil cylinder and high reliability
