Z-Type Reciprocating Piston Compressor Petrochemical Field

The cylinder centerline of the Z - type compressor is arranged vertically to the ground, presenting an upright structure, which can be single - row or multi - row. The piston reciprocates in the cylinder and is connected to the crankshaft through a connecting rod, converting the rotational motion of the crankshaft into the linear motion of the piston. When the piston moves downward, the volume of the cylinder increases, the pressure decreases, and the outside gas enters the cylinder under the action of the pressure difference. When the piston moves upward, the volume of the cylinder decreases, the gas is compressed, and the pressure rises. When the gas pressure in the cylinder reaches a certain value, the exhaust valve opens, and the compressed gas is discharged from the cylinder. It is applied in industries such as chemical engineering, pharmaceuticals, food and beverage, etc., to provide compressed air and power support for production equipment and processes. In air - separation plants, it is used to compress gases such as oxygen and nitrogen to achieve gas separation and purification. In some small - scale refrigeration systems or air - conditioning systems, it can serve as the core component of the compressor refrigeration cycle.
