How to Maintain Loading Arms Daily?
Daily maintenance is crucial to ensure the normal operation and service life of loading arms. The first is the regular inspection of components. It is necessary to regularly check the wear and aging of rotary joints, seals, and other key components. If problems such as oil leakage or poor sealing are found, they should be replaced in time. At the same time, check the integrity of safety devices such as emergency breakaway valves and electrostatic grounding devices to ensure that they can work normally.
Secondly, lubrication maintenance is required. Regularly add appropriate lubricants to the rotary joints and other moving parts to reduce friction and wear and ensure the flexible rotation of the arm. For loading arms used in harsh environments such as high temperature, low temperature, or strong corrosion, it is necessary to strengthen the inspection and maintenance frequency, and clean the surface of the equipment in time to avoid corrosion of the equipment by residual materials. Finally, establish a complete maintenance record to record the maintenance time, content, and replaced components, which is convenient for tracking the operation status of the equipment and formulating a reasonable maintenance plan.
Safety devices are an important part of loading arms, which play a key role in ensuring the safety of material transfer operations. The most core safety device is the emergency breakaway valve. When the transport vehicle accidentally departs during the loading and unloading process, the emergency breakaway valve can automatically cut off the connection between the loading arm and the vehicle within a very short time (usually within 0.3 seconds) and realize double sealing at both ends, completely avoiding material leakage caused by pipeline tearing.
In addition, loading arms are usually equipped with electrostatic grounding devices. During the material transfer process, static electricity will be generated due to the friction between the material and the pipeline. The electrostatic grounding device can timely export the static electricity to the ground, avoiding the risk of fire and explosion caused by static accumulation. For loading arms used in special scenarios, there are also corresponding special safety devices. For example, those used for transferring toxic and harmful gases are equipped with leak detection sensors, which can trigger an acousto-optic alarm immediately when a leak is detected. Those used for high-pressure material transfer are equipped with safety valves to release excess pressure and prevent pipeline rupture.
