Prestressed computer numerical control precision tensioning equipment is mainly composed of computer synchronous control station, synchronous hydraulic sub-stations, tensioning hydraulic cylinders, pressure sensors and hydraulic system accessories, large diameter high strength finish-rolling screw and nut etc.

This system is composed of 1 high pressure pump station, control valve groups, hydraulic cylinders, stroke monitoring devices, pressure monitoring devices and 1 set of electrical control system. Hydraulic pump station controls the flow by on-off valve, depending on regulating the switch frequency to change the flow which achieves the purpose of output flow can be regulated continuously.

Electronic control system is the key to realize synchronous actions. It is based on the theory of closed-loop control system, the displacement signal of heavy moving as a controlled parameter, the pressure signal generated by heavy objects in force chamber of hydraulic cylinder is taken as a reference.

Plunger hydraulic pump equipped with balance valves, guarantee hydraulic cylinders in oil-taking speed control when lifting and lowering, alleviate the effects of hydraulic impact on the synchronous accuracy, can lock the hydraulic cylinders without leakage, ensure hydraulic cylinders will not fall freely in case of accidental power failure and make the load of the hydraulic cylinder will not be out of control.

Hydraulic weighing synchronous lifting system is a multi-function hydraulic system controlled by a PLC (programmable controller), lifting the load by hydraulic jack (no need additional auxiliary lifting equipment), transferring weight of load to the hydraulic jack, and then detected by high-precision sensor, calculated by designed software, the final weight can be reflected on the screen, and printing out the data can be achieved.

70Mpa working pressure, to achieve lightest weight of cylinder with the same tensioning force, reduce labor intensity. Standard safety valve, protects the cylinder from damage of overload and ensures safe and reliable use. Double acting, hydraulic return; baked enamel finish for increased corrosion resistance.

With a double load positioned over one cylinder, that cylinder would stall while the opposite cylinder tries to extend. When using flow-control synchronization, size each cylinder to carry the whole load if the load might get off center. When controlling hydraulic cylinders, it is best to use pressure-compensated flow controls.
