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.

Electric Stacker pressurization system common failure analysis and troubleshooting

March 13, 2012 Read 1814 times Tags: Electric Stacker Full Electric Stacker Semi-Electric Stacker Stacker
Summary: Electric pallet truck Stacker power cylinder vacuum brake system determines the level of the vacuum booster booster effect is good or bad. The power cylinder vacuum reasons for the decline are: vacuum pumps, vacuum valve and air valve performance is poor or breakage of the power cylinder coating, wherein the vacuum valve, air valve seal bad most common. If the vacuum valve is not sealed, when the pedal is pressed, while the vacuum valve is closed, but the air from the vacuum valve and seat can still penetrate between the front chamber of the power cylinder, causing the power cylinder vacuum decreased, so much thrust rod reduced, can not form the auxiliary cylinder pressure, thereby reducing electric stacker braking performance.
A, Electric Stacker insufficient vacuum booster booster causes and corresponding solutions
Electric Stacker vacuum booster by a pressurized cylinder (auxiliary cylinder), the control room, adding strength to the vacuum chamber (power cylinder) three kinds of composition.
Control valve diaphragm divided internally by about two chambers. Vacuum valve and air valve are one, relying on spring action. Stacker not brake in time, the vacuum valve and the diaphragm seat center hole between the normally open and normally closed air valve to maintain the state. Power cylinder divided by the film before and after the chamber, the first chamber is connected with the vacuum tank, vacuum tank with a vacuum pump connected via a tube; rear chamber through a pipe connected with the right chamber of the control valve. When the electric engine start without Stacker depress the brake pedal is taken, the vacuum booster power cylinder before and after the chamber and the control valve to the left and right chamber so connected with each other with the same degree of vacuum, so the return spring under the action of the power cylinder rod coating in the center rearward limit position.
When electric stacker engine starts, brake pedal, when oil rose to a certain value of the master cylinder brake fluid when its input turbocharger, all the way through the center hole of the flow of the auxiliary piston front left and right brake cylinder; all the way to the right to promote the control valve piston, diaphragm seat to close the vacuum valve, the control valve left and right two chambers isolated (equivalent to the power cylinder before and after the spleen every child) and then open the air valve, after the cavity is filled with the power cylinder air, and the first chamber to maintain a certain degree of vacuum remains. Therefore, before and after the chamber creates a pressure differential to force the power cylinder rod to move forward driven diaphragm, putting the ball off first with the top dead center of the auxiliary piston bore, which in turn push the piston forward, to the master cylinder to the oil plus pressure (boost), and thus obtain a higher brake cylinder hydraulic, electric stacker makes for good braking performance.
Seen from the above works, electric stacker power cylinder vacuum brake system determines the level of the vacuum booster booster effect is good or bad. The power cylinder vacuum reasons for the decline are: vacuum pumps, vacuum valve and air valve performance is poor or breakage of the power cylinder coating, wherein the vacuum valve, air valve seal bad most common. If the vacuum valve is not sealed, when the pedal is pressed, while the vacuum valve is closed, but the air from the vacuum valve and seat can still penetrate between the front chamber of the power cylinder, causing the power cylinder vacuum decreased, so much thrust rod reduced, can not form the auxiliary cylinder pressure, thereby reducing electric stacker braking performance.
Similarly, if the air valve leak, did not step on the brake pedal before the power cylinder had penetrated the air chamber, the vacuum power cylinder when the pedal is more greatly reduced. Therefore, the control valve of the vacuum valve, the air valve is a vacuum booster booster lack the most common point of failure. From our years of maintenance practice, vacuum pump oil is caused by electric stacker vacuum booster damaged a fatal factor. Because vacuum system into the oil can cause the valve, coating damage, if there is pumping oil phenomenon will promptly repair or replace the pump. In addition, the pump performance is not good, connecting pipeline leakage and breakage Kuang Yung Pak Doo-ho and other fabrics have made straight into the turbocharger pressure is insufficient.
