Thông tin chi tiết

The Atlas Copco 1623992500 thermostat is a mechanical temperature-regulating valve core. It controls the flow path of lubricating oil inside oil-injected screw compressors . Specifically, Atlas Copco engineers this component for the GA200-250VSD variable speed drive compressor series. The valve weighs 299.8 grams and measures 40 by 40 by 100 millimeters. Despite its compact size, it plays a critical role in compressor thermal management. Without a functioning thermostat, the compressor cannot maintain optimal oil temperature. Consequently, both efficiency and component longevity suffer.

Product Overview

The Role of Oil Temperature in Screw Compressors

Oil-injected screw compressors rely on lubricating oil for three simultaneous functions. First, the oil lubricates the rotors and bearings. Second, it seals the clearance between male and female rotors. Third, it absorbs the heat generated during compression. The injection oil can reach temperatures above 100°C under full load. Therefore, a cooling circuit must remove this heat before the oil re-enters the compression chamber.

The thermostat valve sits at the intersection of two oil flow paths. One path routes oil through the oil cooler. The other path bypasses the cooler and sends oil directly back to the airend. The valve core mechanically selects the correct path based on oil temperature. This selection happens without electrical signals or controller intervention. Instead, a temperature-sensitive element inside the valve expands and contracts in response to oil temperature changes.

Application in GA200-250VSD Compressors

The 1623992500 serves the GA200-250VSD series. These compressors deliver motor power from 180 to 320 kW and cover working pressures from 3.5 to 10.9 bar(g). In VSD compressors, the motor speed varies continuously based on air demand. This variation means the compression heat load changes constantly. The thermostat valve must respond to these dynamic conditions and maintain stable oil temperature across the entire operating range. A malfunctioning thermostat in a VSD compressor can cause either overheating at high speed or condensation buildup at low speed.
