CQJ type accumulator Gas charging tool

Short Description:

CQJ type accumulator Gas charging tool is a matching product for filling nitrogen into NXQ type accumulators. It can be used for charging, discharging, measuring, and correcting the charging pressure of the accumulators. CQJ type accumulator Gas charging tools are also suitable for applications in the fields of metallurgy, electric power, and other industries that require filling high-pressure gas into high-pressure containers. It can be used not only for charging nitrogen into energy accumulators, but also for charging nitrogen into nitrogen springs. It is suitable for charging nitrogen into energy accumulators, gas springs, pressure storage devices, high-voltage switches, electrical products, injection molds, high-pressure containers, fire-fighting equipment, etc. that require nitrogen charging.
Brand: YOYIK


Product Detail

Determination of inflation pressure

The inflation pressure can refer to the following values:

1. Impact buffer: use the common pressure at the accumulator set point or a slightly higher pressure as the inflation pressure;

2. Pulse damping: 60% of the average pulse pressure is used as the inflation pressure;

3. Energy storage: The inflation pressure should be determined within the range of 90% below the minimum working pressure of the system (typically 60% to 80%) and 25% above the maximum working pressure;

4. Thermal expansion compensation: The lowest or slightly lower pressure in the closed circuit of the hydraulic system is used as the inflation pressure.

Precautions for use

1. The accumulator must be inspected before filling with nitrogen

2. When filling nitrogen, proceed slowly to prevent bursting the capsule.

3. The accumulator cannot be filled with nitrogen, compressed air, or other combustible gases.
