liftstar electric stacker Troubleshooting internal combustion forklifts hydraulic mechanical transmission system are

Troubleshooting internal combustion forklifts hydraulic mechanical transmission system are: output power shortage, the initial difficulties, shift unresponsive; oil temperature is too high and the torque converter does not work.
Failure Analysis
If viewed from the observation hole of the torque converter to the torque converter does not work, you should first check the oil return into the oil and torque converter, Semi Electric Stackers if not back to the oil, and the truck with normal cold and hot cars travel difficulties, the cause of the failure to compensate pump badly worn or damaged; if the torque converter without power output, while sometimes working without work, the cause of the malfunction is the oil plug, inside idler pulley seat or seat cover is damaged nut loosening.
If the oil temperature is too high, the usual reason is: the oil pump oil blockage caused by inadequate compensation amount, the clutch dry friction caused by high oil temperature; adjust the pressure inside the torque converter oil pressure falls below the main pressure valve, so that converter outlet pressure is too low; oil grades wrong; converter damage to internal components of the engine's power is only rarely passed to the turbine part, reactive power is too large and cause a sharp rise in oil.
Found in the course of the forklift underpowered, climbing difficulty, shift unresponsive, and load lifting work, the first detection system pressure gauges are available, if less than the required pressure value may be due to: Compensation pumps gear pump for excessive wear, the compensating pump gear pump for excessive wear, so that the increase in the compensation pump leakage; cleanliness bad oil caused oil plug, make compensation platform stacker sucked empty.
Troubleshooting
As can be seen from the above analysis, the truck's hydraulic mechanical transmission failure is mainly the oil, torque converter and compensation pump these three aspects. Therefore, the first consideration should be to clean up the oil troubleshooting, replacing the oil and oil filter as required; then check the torque converter and compensation pump these three aspects. Therefore, the first consideration should be to clean up the oil troubleshooting, replacing the oil and oil filter as required; then check the torque converter guide wheel, seat and clutch pulley for damage; and finally check the pump to compensate for wear and repair or replace damaged components. Must clean up the oil radiator Electric pallet truck surface dust and dirt. Were above treatment, generally better troubleshooting.

After working for some time part of the truck, in the work unit load drop, hydraulic oil often ejected from the tank respirator, accompanied by the sound of a steam jet outside pallet jack.
The hydraulic oil tank truck for common industry Semi Electric Stackers open structure, gas within the fuel tank to atmosphere through the respirator, when the return pipe back to the oil, the excess air within the tank is discharged through the respirator. Preliminary analysis of the reasons is the lack of a respirator injector ventilation, but after working for some time to remove the respirator, the problem still exists. Remove the oil filler cap test, after working for some time to directly cover the hydraulic oil ejected from refueling.
Its brake pump, steering, multi-way valve and mast cylinder return pipe ports are arranged above the hydraulic oil level, and the nozzle is on the steel suction tube. Scene observed when working device with load drop, a lot of oil quickly back to the oil return pipe through the mouth after playing in the high-speed suction pipe, forming intense splash. After computer rentals hydraulic oil temperature, but also produce a lot of oil droplets and mist the tank, so that a sharp increase in air pressure inside the tank. The oil, the oil droplets and mist, and ultimately through the respirator rapid discharge. Due to the blocking effect of the filter, the oil droplets and mist through the filter respirator piled up in the fuel tank, under outside pressure difference of the role of the high-speed jet of hydraulic oil from the respirator pallet Electric hydraulic stacker jack.
Because of these problems forklift hydraulic tank, through research, we decided to go back on the hydraulic tank tubing re-arranged location. Body as follows: the return oil return pipe frequent brake pump, steering return line and multi-way valve is arranged in the return line of all hydraulic oil below the surface, its back to the oil port and suction tube position offset from each other and, if possible pull these big oil return port and respirator distance.
After the return line above the forklift rearranged, back to the oil frequently three return port below the liquid level, avoiding the high-speed crash back to the oil suction tube and produce oil droplets or mist, tank respirator injection disappears. Furthermore, this improved hydraulic components also play a Manual drum Stacker protective role, but also to extend the service life of hydraulic oil.
