315kw Two-Stage Permanent Magnetic Variable-Frequency Screw Air Compressor for Air Tank Testing
Customer type
Large pressure vessel manufacturing plants (pressure testing for gas storage tanks/reactors/heat exchangers), third-party non-destructive testing companies, boiler and pressure vessel quality inspection institutes, petrochemical pipeline pressure testing contractors, military/aerospace ground support units, and large bottle inspection stations (centralized gas source stations).
Core pain points
1. The pressure test requires a large flow rate for rapid pressurization (due to the large volume of the tank), which is too slow for small models;
2. Pressure testing is an intermittent operation but lasts for several hours at a time, and the no-load power consumption of ordinary power frequency machines is astonishing;
315Kw belongs to ultra high power, and electricity is the core cost. PM VSD+two-stage compression must be used to minimize the specific power;
4. The pressure should be stable at 7-13bar and equipped with automatic pressure holding, without overshoot;
5. The factory has an industrial power grid (380V/415V/440V) and does not require diesel engines.
Typical scenario
Gas storage tank pressure test (0.8-1.3MPa pressure holding for 30 minutes), pressure resistance verification of reaction kettle, segmented gas test of long-distance pipeline, centralized high-pressure gas source for bottle inspection station, and pneumatic tool master station for heavy industry workshop.

Advantages
1. The most advanced split type design
2. The air end and motor are connected by the coupling, free from the trouble of maintenance.
3. Double screw highly efficient air end design of large rotor, larger compressed capacity, longer service life with imported SKF bearings.
4. Permanent magnet motor
The motor is made of the special material of rare-earth permanent magnet, strong magnetic field, large overload torque and small current while starting and operation,
The special rare-earth permanent magnet with the special design of the rotor, makes the efficiency of the motor 10%-15% higher than the same horsepower induction motor.
Design of the lower temperature, the raise temperature of the motor<60K, greatly improves the service life and service factor.
Soft starter by the inverter
Avoiding the strong mechanical shock while starting, prolonging the life of machine, reducing the maintenance, improving the reliability. So it can save 30% energy.
