The CQJ-D-H nitrogen charging tool is an efficient and reliable supporting product designed specifically for NXQ type accumulators. Its main functions include multiple operations such as inflation, exhaust, air pressure measurement, and correction of inflation pressure, providing a convenient solution for the maintenance and debugging of hydraulic systems.
Usage of CQJ-D-H nitrogen filling tool:
Before testing or adjusting the pressure of the accumulator, it is necessary to disconnect the accumulator from the system and empty the liquid inside. Prepare nitrogen cylinders or nitrogen charging carts with sufficient pressure. Screw the adapter inflation connector into the accumulator inflation valve and ensure that the pressure relief valve is closed. Then, turn the hexagonal screw of the spindle counterclockwise to open the air valve. After inflation is completed, open the pressure relief valve and release the nitrogen inside the nitrogen charging tool.
The flexibility and versatility of the CQJ-D-H nitrogen filling tool make it widely used in multiple fields and scenarios, providing efficient and reliable tool support for the maintenance and debugging of various hydraulic systems.
