There are some details you need to know in the process of maintaining the hydraulic road blocker. What do these details mainly include? I’ll take you to know more about this problem.
1. In the process of electrical maintenance, the relevant power supply shall be cut off in time, and signs such as maintenance and overhaul shall be hung on obvious positions.
2. Check the working condition of switches, buttons, indicator lights, and buzzers once a month.
3. When there are vehicles or pedestrians above the turnover barrier machine, lift it strictly to avoid harm.
4. Keep the drainage at the bottom of the turnover barrier body unblocked and the surroundings clean to ensure the service life, performance, and waterproof tightness of the lifting barrier machine parts.
5. During the operation of anti-terrorism automatic road blockers, prevent continuous rise and landing. Rising and falling are not suitable for continuous fast switching, which is easy to shorten the service life of the motor and hydraulic pumps.
6. On large ice and snow days, if there is serious ice inside the pile body of the roadblock machine, stop lifting and use it after freezing by heating and other methods.
7. Regularly check the oil level in the oil tank of the anti-collision road blocker. If the oil level is lower than the bottom line, add oil; If the oil becomes dark and turbid, you need to consider changing the oil.
Whether the road blocker is worn?
Next, let’s introduce the method to judge whether the anti-collision road blocker is worn.
Road blocker is a traffic security facility with good characteristics, such as anti-collision, anti-terrorism, anti-rust, corrosion resistance, long service life, etc. It is widely used in government units, nuclear power plants, and other places. The anti-collision roadblock machine can be used together with automatic rising bollards and parking barrier gates or used alone. It is mainly composed of a mainframe, hydraulic transmission station, and electric control system.
However, when using the anti-collision road blocker machine in life, there may be different degrees of wear. If the hydraulic anti-terrorism road blocker machine has the function of machinery, it will collide, and the collision will inevitably wear. How many manifestations of the wear of the anti-collision road blocker machine? Let’s take a look:
1. There are three periods of wear of the anti-collision road blocker machine. The running-in period: due to the rough surface of the conflicting pair and the slight error during installation, the flatness of the conflicting pair is poor, the normal load is large and the wear is fast, which also depends on the situation of the conflicting pair itself.
2. During the normal wear period, if the collision pair cooperates normally, wears normally, and has the minimum wear and collision, the operation time of the anti-collision road blocker machine will be long. If the wear reaches a certain degree, it will enter the limit wear period, and the wear will increase at this time.
3. If the anti-collision automatic road blocker machine has the function of machinery, there will be a collision. If there is a collision, there will be wear. There is a rule of wear: that is, the volume wear is directly proportional to the relative sliding interval of the collision pair; The yield strength proportional to the normal load is inversely proportional to the hardness.
On the basis of theory, it is proved by experiments that the correlation between wear rate and impact element is very small. Generally, there is a level difference between impact elements, and there will be three levels of difference in wear rate. Therefore, the change of impact coefficient is not fixed.Sharing this:
