High Quality Gas Charging Cart 

prodct name: high quality gas charging cart

1. general description.

CDZ - D1 nitrogen filled the car is suitable for the NXQ series hydraulic capsule accumulator, hydraulic piston accumulator, the hydraulic diaphragm accumulator (including import accumulator) and other special high-pressure container filling, charging nitrogen pressurization device, at present, the maximum pressure of nitrogen pressure of 35 mpa, the type of nitrogen charging car is developed by our company is a new type of nitrogen pressurization device, already obtained the national patent, patent number for ZL03229074.8. In 2003 was named "China hydraulic pneumatic sealing industry excellent new product", this type of nitrogen charging car has the advantages of novel structure, small volume, low noise, easy to operate, supercharging effect is remarkable, etc, by the national major iron and steel (group), aerospace, heavy machinery, military industry, etc. The user's high praise

2. working principle.

The nitrogen filled the car by the hydraulic system, pneumatic system and circuit system, etc, when pressure oil through electromagnetic directional valve into the pressure cylinder inferior vena, push the piston up, into the pressure cylinder start nitrogen pressurization and cavity on the one-way valve, pneumatic tools, filling the accumulator (or high pressure container), when the piston booster device on the run up to the top, the hydraulic system pressure rises to the semiconductor pressure relay setting the highest pressure, the semiconductor pressure relay signals, power electromagnetic directional valve, piston under the action of air pressure, run down; Hydraulic system pressure began to decline, when to semiconductor pressure relay setting minimum pressure, semiconductor pressure relay signals after delay timer delay 5 to 20 seconds, the electromagnetic directional valve electricity, the piston began to run up; So running up and down reciprocating piston until the exhaust pressure to the highest pressure of semiconductor pressure relay setting 0, the semiconductor pressure signal to cut off the motor and power supply system.
