Points of Attention During the Disassembly of a Diaphragm Accumulator

When disassembling a diaphragm accumulator, the following are some key points to note to ensure safety and accuracy of operation:
1、 Safety preparation
Ensure system security:
Stop the operation of the system and release the pressure inside the system in an appropriate way to ensure that the system is in a safe state.
Use appropriate tools and equipment to reduce pressure in the system and ensure safe and controllable disassembly process.
Personal protection:
Wear personal protective equipment such as protective goggles and gloves to avoid injury during operation.
2、 Preparation before disassembly
Tool preparation:
Prepare necessary tools such as wrenches, ring wrenches, pointed pliers, screwdrivers, hammers, etc., as well as fabrics and other cleaning agents required for cleaning.
Check the working status:
Conduct a comprehensive inspection of the diaphragm accumulator to ensure that there is no damage to its appearance and that the diaphragm has no cracks or signs of wear.
If any abnormal situation is found, the diaphragm should be replaced or necessary repairs should be carried out in a timely manner.
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:
Use appropriate tools to loosen the protective cap for subsequent operations.
Release nitrogen:
Use a nitrogen filling tool to release the nitrogen inside the capsule, ensuring that the internal pressure is zero.
Dismantling connecting components:
Disassemble the valve core, nut, seal and other components in sequence, paying attention to the disassembly sequence and preserving the disassembled parts.
Remove the stop bolt, flange, stop nut, and seal to slide the oil valve into the housing.
Take out the capsule:
Remove the elliptical gasket from the oil valve and then remove the capsule from the accumulator.
By following the above steps and precautions, the safety and accuracy of the operation when disassembling the diaphragm accumulator can be ensured.
