An effective energy-saving measuresmetric hydraulic fittings

The hydraulic system accumulator set in the main loop, whose role is to provide large flow of oil in each pai r of hydraulic cylinders stretched out, returned, and reduce the hydraulic pump displacement of the accumulator and electric contact pressure gauge electromagnetic relief valve and check valve used in conjunction with the hydraulic pump in a correction cycle, only about working load, the rest of the time are unloading state. This is because the general long-straightening tube meters, the distance between the correction roller with the first pair of corrective roll m, the hydraulic cylinder when the steel pipe into the host after all, only by correcting a roll of steel pipe exert corrective force, does not require flow, the pressure of the main circuit soon reach electric contact pressure gauge pressure contact settings for adjustment of the maximum correction force, high-pressure contact conduction, instruction solenoid is energized by the electromagnetic relief valve hydraulic pump unloading. Only when the low pressure of the main circuit to the electric contact pressure ga uge low-voltage contacts for adjustment of the settings according to the lower limit of the correction only force, low-voltage contact conduction, instruction electromagnet power failure, the hydraulic pump was re-load work. In addition, the hydraulic system in the air during operation of the non-correction tube, the solenoid is energized, the pump has been in the unloading state, so the actual energy consumption of the system is very small.

Second, the photoelectric switch instruction controlhydraulic quick coupling

The system uses the position of the photoelectric switch feelings correction steel pipe road works reliably, and fast to install, easy to adjust, and long life characteristics

Third, the technical design of hydraulic manifold blockshydraulic hose crimping machine

All hydraulic control valves are used in the hydraulic system connection plate, placed in the hydraulic manifold block integration of the hydraulic manifold block by block valve block installation, assembly, adjustment, replacement, repair and maintenance are very convenient. Valve block software design, a map, not only greatly improve the design efficiency, but also to ensure the quality of the design, reducing the consumption of the valve material, and indirectly reduce energy consumption.
