What to Look Out for When Disassembling a Diaphragm Accumulator

When disassembling a diaphragm accumulator, there are several key points that need special attention to ensure the safety and effectiveness of the operation. The following is a detailed analysis and summary:
1、 Safety preparation
Ensure system safety: Firstly, ensure that the entire hydraulic system is in a safe state. Stop the operation of the system and release the pressure inside the system in an appropriate way to prevent accidents during disassembly.
Use appropriate tools: Use appropriate tools and equipment to reduce pressure in the system and ensure safe and controllable disassembly process.
2、 Preparation before disassembly
Check the working condition: Conduct a comprehensive inspection of the diaphragm accumulator, including whether there is any damage to the appearance and whether there are cracks or signs of wear on the diaphragm. If any abnormal situations are found, the diaphragm should be replaced or necessary repairs should be carried out in a timely manner.
Prepare necessary tools: Prepare necessary tools and equipment such as wrenches, screwdrivers, hydraulic pumps, etc.
System emptying: Confirm that the system where the accumulator is located has been emptied and ensure that the storage pressure of the accumulator has dropped to zero.
3、 Disassembly steps
Unscrew protective cap: First, unscrew the protective cap and use a nitrogen filling tool to release the nitrogen inside the capsule.
Remove the valve core: Use an air valve wrench to remove the valve core, and remove the nuts and seals in sequence (pay attention to the order).
Remove other components: Remove the stop bolt, flange, stop nut, and seal on the other side to slide the oil valve into the housing. Remove the elliptical washer on the oil valve to remove the capsule.
4、 Precautions
Completely release pressure: Before disassembly, the pressure inside the accumulator must be completely released, otherwise it may cause serious injury.
Prevent oil leakage: During the disassembly process, be sure to pay attention to preventing oil leakage to avoid contamination and danger.
Use special tools and cleaning agents: During cleaning and inspection, special tools and cleaning agents should be used to avoid secondary pollution or damage to the accumulator.
By following the above steps and precautions, the safety and effectiveness of the operation when disassembling the diaphragm accumulator can be ensured.
