How to check the pressurization system failure of the handling forklift?


Release time:

Jun 30,2022

Now it is common to use forklift to carry goods, because it can easily lift large, medium and small goods, especially large goods. Generally, the volume is large or the weight is heavy, and two or more people are required to carry it at the same time, which greatly reduces the handling efficiency.

Now useHandling forkliftHandling goods has become commonplace because it can easily lift large, medium and small goods, especially large goods. Generally, the volume is large or the weight is heavy, and two or more people are required to carry it at the same time, which greatly reduces the handling efficiency. If you use a handling forklift, you can easily handle it as long as you operate the stacker correctly. However, it is inevitable that there will be various problems in the use of forklift trucks, which need to be checked by relevant personnel. Take the booster system as an example to see how to check the fault.

Inspection of 1. Vacuum Booster

1. Check first and then listen, that is, start the engine for a few minutes, then turn off the engine and step on the brake pedal several times. Every time you can hear the vacuum booster make a "hissing, hissing" sound. If the sound is loud and gradually weakens as the number of pedals increases, it can be basically concluded that the performance of the vacuum booster is good.

2. Start the engine, step on the brake pedal and keep it still, so that the vacuum valve and 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 wisp at the air filter port of the vacuum booster Cotton yarn, there should be no suction phenomenon); the other person removes the air pipe of the rear chamber of the power cylinder, and quickly blocks the air nozzle and the rear chamber pipe joint with his fingers. If the suction nozzle has suction, the vacuum valve is not sealed and should be repaired or replaced. If the connector has suction, the diaphragm of the power cylinder is damaged and needs to be replaced.

3. Start the engine, do not step on the brake pedal, and put a wisp of cotton yarn in the air filter port of the control valve. If the cotton yarn is sucked, the air valve is leaking. The control valve must be disassembled and inspected and the flapper or air valve replaced.

2.Handling forkliftThe fault of vacuum booster system shall be judged and eliminated according to the following methods

1.Handling forkliftInspection of the vacuum pump, manual inspection: remove the pipe joint of the vacuum pump, plug the pipe joint of the vacuum pump with your fingers, and start the engine. If the finger is sucked, the vacuum pump is in good condition; if the suction is weak, the vacuum pump is malfunctioning and needs to be repaired.

2. Vacuum gauge check: Connect the vacuum gauge to the vacuum tube and start the engine. Regardless of the engine at any speed, the vacuum should not be less than 500mm Hg, otherwise the vacuum pump should be repaired or replaced.

3.Handling forkliftHow to prevent the goods from slipping in operation

Some storage enterprises will think that as long as the fall prevention shelter is not damaged, it is qualified, but the internal quality can only be concluded in the test and inspection items, and the quality cannot be judged by visual inspection in daily work. Only through testing and inspection can it be foolproof. In addition, before leaving the factory, the sunshade frame should be sent to the legal unit for re-inspection two years after leaving the factory, and then it should be inspected once a year, because these carelessness will plant the seeds of potential safety hazards. Therefore, special equipment like this must be routinely inspected and maintained by professionals. Don't get too lucky. The shutter of the gantry frame will not have any problems, that is, the shutter of the gantry frame may have safety problems. But if there is a safety accident, it will be too late to regret.

The troubleshooting method of the power-assisted system of the electric stacker introduced above hopes that you can check your own after reading it.Handling forklift. In fact, it is very necessary to check these mechanical equipment, so as to reduce the probability of failure in use, so as not to delay work efficiency.
