Screw refrigeration compressor
Thread Content
When an open-type screw compressor increases or decreases its load, does the speed of the rotor change accordingly?
An open-type screw compressor is a device that features a pair of male and female rotors for compressing gas, has no suction or discharge valves at either end of the cylinder, and regulates the gas flow by using an oil piston controlled by oil pressure to move a slide valve； The function of the balance piston is primarily to counteract the axial forces on the male rotor. The lubricating oil injected through the injection holes in the slide valve serves to cool, lubricate, and seal the volume elements that are under compression.
No. Load is increased or decreased by moving the hydraulic slide valve.
No, it’s just an increase or decrease in the amount of air inhaled
