Hydraulic machine repair major maintenance projects including: oil system the overhaul and hydraulic components replacement, maintenance and electrical components of the circuit system replacement, hydraulic cylinder repair and replacement of oil seals, repair of the cylinder piston rod, wearing machinery spare parts replacement. Hydraulic Machine Repair Service Area: Guangzhou region (including Panyu, Huadu), Shenzhen, Dongguan, Foshan, Zhongshan, Guangdong Province, in other cities and regions. Faults and troubleshooting of hydraulic machines (Optional copy sporadic for reference) (1), the oil viscosity is too large or too high an oil temperature rise, check the motor turning 2 dredge pipeline cleaning filter, a new oil 3 to check to replace the parts, fastening each connected at the screw, to avoid leaks, take strict precautions against air mixed with 5, the correct selection of the fluid control the temperature rise Noise severe pressure fluctuations powerful 1 suction pipe clogged filter or filter small capacity, the suction pipe seal leak or oil bubbles, pump and coupling heart 4, low oil level 5, the oil temperature is low or high viscosity 6, pump bearing damage, clean the filter allows suction tube patency, the correct selection of filter 2 is add a little oil or sealed at joints, such as noise reduction, tighten the connector or replace seals; return pipe port below the oil should have a certain distance from the suction pipe, adjust concentric 4 refueling solution 5 the oil is heated to the appropriate temperature, check (hand touch) the pump bearing part of the temperature rise of the pump shaft neck oil seals oil spill oil spill pipeline fluid resistance of the pump body pressure rises to more than the allowable pressure value oil seal check piston pump on the pump drain port with separate tubing directly connected to the fuel tank. If it is found to the the few piston pump leak tubing parallel in a same diameter Explorer and then turned on the fuel tank, or the piston pump drain line connected to the total return pipe, should be corrected. Best pump leak oil port connected to a pressure gauge to check the pressure of the pump body, its value should be less than 0.08MPa
