Electric stacker trucks require manual intervention inspections to test compliance with their pressurization systems

It is not uncommon to use electric pallet trucks to transport goods, because it can easily electric pallet lift truck and transport large, medium and small goods, especially large ones. Generally, the volume is larger or the weight is heavier. When manual handling is required, two or more people are required to carry it at the same time, which greatly reduces the handling efficiency. If an electric stacker is used, it can be easily handled. , as long as the stacker is operated correctly. However, various problems will inevitably occur when the electric stacker is used, which requires relevant personnel to conduct inspections. Let's take the booster system as an example to see how to check the fault.

I. Inspection of the vacuum supercharger

1. Check first and then listen, that is, start the engine for a few minutes and then turn off the engine. Press the brake pedal several times, and every time you can hear the sound of 'hissing, hissing' from the vacuum booster. If this sound is loud and gradually weakens with the increase of the number of pedaling, it can basically be concluded that the vacuum booster is device performance is good.

2. Start the engine, step on the brake pedal by one person and keep it still, so that the vacuum valve and the air valve in the control valve are closed at the same time, and the brake is in a balanced state (at this time, a strand of cotton yarn is placed on the vacuum booster. There should be no inhalation at the air filter port of the compressor); another person removes the rear cavity air pipe of the power cylinder, and quickly blocks the air pipe port and the rear cavity pipe joint with their fingers. If the pipe port has suction, it means vacuum If the valve is not sealed, it should be repaired or replaced; if the joint has suction, it means that the power cylinder membrane is damaged and must be replaced.

3. Start the engine, do not step on the brake pedal, and place a strand of cotton yarn at the air filter port of the control valve. If the cotton yarn is sucked, it means that the air valve is leaking, and the control valve must be disassembled and inspected. Replace the apron or air valve.

2. After the vacuum booster system of the electric stacker fails, it should be judged and eliminated according to the following methods

1. Inspection of the vacuum pump of the electric stacker, manual inspection: dismantle Lower the pipe joint of the vacuum pump, block the interface of the vacuum pump pipe with fingers, and start the engine. If the fingers are sucked, the vacuum pump is good; if the suction is weak, the vacuum pump is faulty and needs to be repaired.

2. Vacuum gauge inspection: connect the vacuum gauge to the vacuum tube, start the engine, no matter the engine is at any speed, the vacuum degree should not be lower than 500mm mercury column, otherwise the vacuum pump should be repaired or replaced.

3. How to prevent the goods from slipping during the operation of the electric stacker

1. Some warehouse companies will think that as long as the anti-falling shielding frame is not damaged, it is qualified, but the internal quality is only The conclusion can only be drawn in the engineering of testing and inspection, and it is impossible to judge whether it is good or bad by visual inspection in daily work. Only through testing and testing can it be foolproof.

2. In addition, the shuttering frame should be sent to the legal unit for re-inspection two years after the factory leaves the factory, and then inspected once a year, because these inattentiveness will plant seeds for safety hazards. Therefore, special equipment like this must be routinely inspected and maintained by professional personnel. Qiancheng don't hold on to luck. The shutter of the gantry will not cause any problems, that is, the shutter that represents the gantry may not have safety problems. But if it's time for a security accident, it's too late to regret it.

The above is the troubleshooting method for the booster system of the electric stacker introduced by the editor. I hope that after reading it, everyone can check and check their own electric stacker. In fact, the inspection of these mechanical equipment is very necessary, in order to reduce the probability of failure during use, so as not to delay work efficiency.
