It is not uncommon to use electric pallet trucks
to carry goods, because they can easily carry large, medium and small goods, especially large goods. 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 handled easily. , 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 carry out inspection work. Let's take the booster system as an example to see how to carry out fault inspection. 1. Inspection of the vacuum booster 1. Check first and then listen, that is, start the engine for a few minutes and then turn off the engine, step on the brake pedal several times, and you can hear the 'hiss, hiss' sound from the vacuum booster each time , If this kind of sound is loud and gradually weakens as the number of pedaling increases, it can basically be concluded that the vacuum booster performs well. 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, put a thread of cotton yarn on the air filter port of the vacuum booster , There should be no inhalation); another person removes the rear cavity air pipe of the power cylinder, and quickly blocks the air pipe port and the back cavity pipe joints with fingers. If the nozzle has suction, it means that the vacuum valve is not sealed. Replacement; if the connector has suction, it means that the power cylinder membrane is damaged and must be replaced. 3. Start the engine, without stepping on the brake pedal, and place a strand of cotton yarn on the air filter port of the control valve. If the cotton yarn is sucked, it indicates that the air valve is leaking. The control valve must be disassembled and the rubber ring or air valve must be replaced. 2. After the failure of the vacuum booster system of the electric stacker truck, the following methods should be used to judge and eliminate: 1. Inspection of the vacuum pump of the electric stacker truck, manual inspection: remove the pipe joint of the vacuum pump, and block the connection of the vacuum pump pipe with your fingers , Start the engine, if the finger is sucked, the vacuum pump is in good condition; 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 and start the engine. No matter the engine is at any speed, the vacuum degree must not be lower than 500mm mercury column, otherwise the vacuum pump should be overhauled or replaced. 3. How to prevent the goods from falling during the operation of electric stacker 1. Some warehouse companies will think that as long as the fall-proof shielding frame is not damaged, it is qualified, but the internal quality can only be concluded in the test and inspection project. It is impossible to judge good or bad visually in daily work. It can only be foolproof through testing and testing. 2. In addition, the shielding frame must be sent to the statutory unit for re-inspection two years before it leaves the factory, and then inspected once a year, because these carelessness will plant the seeds for potential safety hazards. Therefore, special equipment like this must be inspected and maintained by professional personnel. Don't hold the shutter of the gantry by chance. There will be no problems, that is, the shutter that represents the gantry may have a safety problem. But if it comes to a safety accident, it will be 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 inspect their 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.
