The hydraulic tee machine is an important component in the hydraulic system, and its function is to divide the fluid from one channel to two or more channels. Hydraulic tee machine is generally composed of pipe body, spool, spring and other components, its structure is relatively simple, but the hydraulic tee machine may also malfunction and damage, need to be repaired. This article will introduce the maintenance of hydraulic tee machine from the following aspects.
First, troubleshooting
Before the maintenance of the hydraulic tee machine, it is necessary to first troubleshoot and determine the cause of the failure. The common faults of hydraulic tee machine are as follows:
1. Slow motion: The slow motion of the hydraulic tee machine is generally caused by damage or excessive wear of the spool or spring, resulting in poor movement of the spool.
2. Drip: The reason for the drip of the hydraulic tee is generally the damage of the seal. Common seals include O-rings, gaskets and so on.
3. Noise: The reason for the noise of the hydraulic tee machine is generally the gap between the valve core and the seat is too large or there is noise in the hydraulic system.
Second, maintenance steps
1. Disassembly: First of all, the hydraulic tee machine needs to be removed from the hydraulic system, and then the various parts of the hydraulic tee machine are removed one by one, including the tube body, valve core, spring, etc. It should be noted that the surface of the tube body and valve core should be protected from any damage during the disassembly process.
2. Cleaning: The disassembled hydraulic tee needs to be cleaned to clean the debris and oil dirt. Cleaning agents or gasoline can be used for cleaning, but it is necessary to pay attention to the choice of cleaning agents to avoid injury to parts.
3. Check: In the cleaning process, it is necessary to check the various parts of the hydraulic tee machine one by one. Check whether the gap between the pipe body and the valve core is too large, and whether the seal is damaged. If a problem is found, replace it in time.
4. Maintenance: After checking the problem, the corresponding maintenance needs to be carried out. In general, parts such as seals and spool need to be replaced. If the valve seat is found to be too worn, it will also need to be replaced.
5. Assembly: After the maintenance is completed, the various parts of the hydraulic tee machine need to be assembled one by one. It should be noted that the assembly needs to ensure that the position and direction of the various parts are correct.
6. Debugging: After the assembly is completed, the hydraulic tee needs to be re-installed into the hydraulic system and debutted. Tools such as pressure gauges can be used for debugging to ensure that the hydraulic tee can work normally.
Third, maintenance precautions
1. Master the working principle and structure of hydraulic tee machine to prevent wrong disassembly.
2. When disassembling the hydraulic tee, handle it gently to avoid damaging the parts.
3. When cleaning the hydraulic tee, the appropriate detergent should be selected to avoid parts injury.
4. Check the parts carefully to ensure that problems are found.
5. When replacing parts, choose parts with reliable quality.
6. When assembling the hydraulic tee, keep the working environment clean and avoid debris entering.
7. When commissioning the hydraulic tee, ensure the normal operation of the hydraulic system to prevent secondary damage.
In short, the maintenance of the hydraulic tee needs to be careful and follow the correct steps and precautions to ensure that the hydraulic tee can work normally and ensure the stability and stability of the hydraulic system.
