[Dry goods] Common troubleshooting and maintenance of lifting columns!
Keou automatic lifting column, focus on school traffic safety.
As an important and indispensable facility for campus safety, the lifting column has been widely used in major campuses, mainly to prevent vehicles from entering.
Its main advantages are ease of use and simple operation. However, as an intelligent device, some minor faults may still occur unavoidably. We must discover and deal with these faults in time to avoid affecting the normal use of the lifting column and causing traffic jams!
Today, Keou will explain the common failures of lifting columns to everyone! Absolutely dry goods ~ not quickly collected!
Question one
Press the control button, there is no response from the lifting column
Generally this kind of situation is that the circuit is faulty, you need to check the circuit and check the status of the power supply and fuse.
If the lifting column cannot be started after making sure that it is correct, the motor may be faulty and the damaged parts of the motor need to be checked and replaced.
The Keou lifting column can be manually lowered when it encounters a malfunction and the control keys are not available.
Question two
The cylinder cannot rise or rises slowly
There are generally three reasons for this situation:
The relief valve is too loose
Oil supply system is not smooth
The pressure relief valve is not closed tightly
This requires us to eliminate them one by one to make the ascent speed of the lifting column return to normal.
Question three
The cylinder descends slowly
The main reason for the slower decline of the cylinder and the main reason for the slower rise of the cylinder are not much different, both related to whether the oil supply system is smooth and the relief valve is tight.
Therefore, we should pay more attention to the tightness of these components during normal maintenance and make timely corrections.
Question four
The cylinder will fall down by itself
After a long period of use, this situation is generally caused by the manual pressure relief valve being too loose, which requires us to tighten or close.
Furthermore, the hydraulic oil leaks. In this case, the hydraulic column needs to be repaired, and the hydraulic oil is replenished at the same time.
The last case is the failure of the hydraulic lock, which does not play the role of fixing the cylinder. At this time, the hydraulic lock needs to be replaced to ensure the normal operation of the lifting column.
The above four failures are common types of problems for automatic lifting columns. Through the analysis of these four common failures, we can also find that the beginning of the failure is due to the failure of daily maintenance. The importance of working properly.
Daily considerations
In addition to the regular inspection and maintenance of the lifting column, we also need to pay attention to things in the daily use process:
Daily use
For example, continuous rise and fall, this is easy to shorten the service life of the motor and hydraulic pump, so you can keep the lifting column up or down when not in daily use to avoid excessive wear and tear.
Surrounding hygiene
We need to routinely check the drainage at the bottom of the lifting column and the sanitation and cleaning around it to ensure the performance and working life of the lifting column machinery.
Winter reminder
It should be noted that in winter, it is forbidden to start the lifting column when the lifting column body is frozen or frozen. It can be hydrolyzed and frozen before lifting. This situation is related to the performance of the product itself. The lowest temperature that can be adapted is -30 ℃, which is suitable for most weather.
to sum up
These common lifting column troubleshooting methods can help you quickly find the source of the problem and solve the lifting column work problem, but you should still pay attention to daily maintenance. After all, long-term maintenance is a guarantee for long-term product work!

LED Sensor Batten Lights
LED Sensor Batten Lights has options of microwave sensor and infrared sensor. There are two sensing modes. One is 0-10v dimming, and the other is on/off.
The main difference between these two modes is that the 0-10v dimming mode can set the brightness of the light after the person walks, and the pending time of this brightness can also be set. On/off mode, you can only set the time for the lights to turn off after a person walks, but not the brightness (that is, functions 3, 4 cannot be implemented). The 0-10v dimming mode is more intelligent.
Briefly introduce the function of sensor light:
1. Set up daylight threshold: If the ambient light is higher than the set brightness, the sensing function will not be triggered.
2. Set up the hold time: The time for the light to maintain brightness after the person walks away.
3. Set up a stand-by dim level: set the brightness maintained after the person walks
4. Set up stand-by time: After the person walks, the time to maintain low brightness
5. Set up detection area: Set the detection area.
Toggle button can set the remote distance of remote control and sensor.
If you need sensor lights in factories or warehouses, corridors, or other indoors, you can choose this LED Sensor batten lights. If you need IP66 sensor light, you can choose Sensor Waterproof Light.
