[Rubber cutter machine] will become the cause of the slow: it is to facilitate the next working procedure plastication and cutting rubber adhesive (piece of) piece of equipment, mainly rubber cutting knife, frame, cylinder, base, auxiliary table, hydraulic system, electrical system components, etc. In use after a period of time, rubber cutting opportunity becomes slow, the vision is: [Rubber cutter machine]return speed is slow, there is no maximum return rate. Just on the way back to retreat quickly is not normal, check valve and its task is normal. To develop a way no other task load, low system pressure match, rubber cutting machine outlet flow all input rod chamber [rubber cutting machine], [rubber cutting machine] should be brought in high speed. But found that [rubber cutting machine] return is not only slow speed, and the system pressure is high at this time.
Oil seal trimming machine return not only lack of elasticity, and there is tilted, incur the valve core of oil seal trimming machine after power failed to return to the original position, then slide valve announces the quantity is too small, rubber strip cutting machine for after oil seal trimming machine of oil saving effect. Rubber cutting machine output pressure oil big local by overflow valve back to the fuel tank, the oil seal before trimming machine valve pressure relief valve setting pressure on arrival, that is why d rubber cutting machine, pressure. Provoked return valve core reason of pressure drop increase can also include: stolen goods into the slide valve cracks and then make the valve core to move hard; Of the gap between valve core and valve hole is too small that when the oil temperature rise high and jammed valve inflation; Electromagnet push rod sealing ring of resistance and bones and muscles to make valve solenoid valve hole deformation, etc. Rubber rubber cutting machine only can find out the real reason of clamping, the response way to remove the match easily. Because of big local pressure oil spill tank back, by cutting into the rubber oil seal trimming machine rubber cutting machine with rod cavity of the oil will be less, and rubber cutting machine return no maximum speed. Slide valve means less back in situ, belong to spring reason, should change to pass the spring. If because of the slide valve accuracy is poor, and the radial clamping, deal with slide valve for repairing mold or new preparation of common hatred of taper valve core tolerance. Trace amounts of taper valve core, make best and make it big end in low pressure cavity side, so much can take the initiative to cut PianTeng quantity, also reduced the friction, and then reduce or prevent by the clamping force.
Above is the [rubber cutter machine] will be slow.
