Full feeding crawler rice combine harvester hydraulic machine often can not afford to cut the header, the neutral position can not stop the failure, the main reasons and troubleshooting are as follows: 1. The hydraulic oil is not clean. Replace clean hydraulic oil, clean filter and fuel tank. 2. There is not enough hydraulic oil in the tank. Add hydraulic oil, add to the tank full load more than 2/3. 3. Hydraulic tubing leaks. The main hydraulic pipe is damaged or tight hydraulic pipe joints, should be promptly replaced or repaired, to prevent oil spills. 4. Hydraulic pump wear, seals are not sealed. Repair or replace damaged hydraulic pumps and seals. There is air in the oil circuit After the oil tank is changed or the hydraulic oil quantity is insufficient, air enters the oil circuit, leading to the header can not afford to hang, need to exclude the air. Exhaust method: The hydraulic pump outlet port nut and header hanging down into the oil inlet nut nut two loose start the engine, the hydraulic pump to work, observe the hydraulic pump oil spilled oil, if there is no bubble , Tighten the nut, and then manipulate the lifting handle to raise and lower the header. When the header is raised and lowered to the maximum and minimum two extreme positions, when the hydraulic oil overflowed from the inlet port nut of the cylinder does not have bubbles, tighten the nut. Note that when tightening the nut, the engine should be shut down to ensure personnel safety. 6. Cylinder or seal wear and tear damage. Check cylinder and seal wear damage, replacement or repair. 7. Safety valve (relief valve) is not working properly. After using for a period of time, safety valve closed small Yan, pressure regulating spring deformation. Hydraulic oil pressure is reduced, resulting in header can not afford to hang or hanging slowly. At this time need to be adjusted, the method is: After starting the engine, make the engine running at medium speed, put the hanging handle into the ascended position, loosen the safety valve lock nut, and then loosen the adjusting bolt to make the header cut down completely Lowest position, and then slowly reinstall the adjusting bolt until the header just can be smoothly raised, then the pressure transferred to the hydraulic system is the optimum pressure. If the pressure is too high, it will cause oil heat, gear pumps and other damage due to excessive load; if the pressure is too low, the header can not be successfully suspended. After adjustment, tighten the locknut.
