loading
1. The compressor structure is a symmetrical flat type (D type), with completely balanced inertial forces and inertial moments also fully balanced through counterweights, resulting in very smooth operation.
2. For a wider range of intake, the use of a clearance cylinder can effectively reduce the power configuration of the motor, achieving energy-saving goals.
3. By adopting frequency conversion adjustment, broad intake requirements can be met. There is no need to use pressure regulating devices due to large fluctuations in pipeline pressure, which can save approximately 150,000 yuan in station construction costs.
4. The crankcase and middle body are cast as a single unit, greatly increasing rigidity, and are complemented by a high-precision machining center. The integrated processing of front and rear bearing holes and left and right slideway holes significantly improves the concentricity of the shaft holes, the verticality of the slideways, and the precision of dimensional tolerances, reducing the leakage rate of conventional compressors from 3% to 1%. This means that a 1000Nm3/h compressor will leak 11,200Nm3 less per year, which helps reduce the operating costs of gas stations and minimizes environmental pollution.
5. The cylinder and packing use low-oil or oil-free lubrication, with the oil content of the compressed and purified gas being less than 10ppm, saving approximately 20,000 to 60,000 yuan in annual operating oil costs.
6. The cylinder features a double-acting or reverse differential structure, making assembly and maintenance convenient with fewer specifications and quantities of wear parts. During third and fourth stage compression, the piston rings and guide rings are one specification less than those in conventional compressors, and their quantity is reduced by about one-third, with oiling points also reduced by about one-third, saving approximately 20,000 yuan in annual operating costs.
7. The PLC provides full automatic control, with fault detection, alarm, and shutdown functions during unit operation.
