5 FAQs about [Screw air compressor slide valve]

How to control a screw compressor using slide valve?

Figure 3: Capacity control of screw compressor using slide valve If the slide valve moves towards the suction, the compressor will function at full load similarly if the slide valve moves towards the discharge, the compressor will function at part load. Actually, by moving the slide valve, the initiation of the compression process is altered.

What is a slide valve in a twin screw refrigerant compressor?

Hence the slide valve assists in capacity control of a compressor that results in energy saving too. This article focuses on a semi-hermetically sealed twin screw refrigerant compressor. In semi-hermetically sealed compressor, the motor and the compressor are enclosed in a bolted casing.

How does a slid valve affect the capacity of a compressor?

e lower capacity range of operation.Elements of the slid valve that work together to determine the capacity of the compressor are:Axial location of the suction end of the slide valve, Zsv. Movin the slide valve away from the slide stop and towards the discharge end of the compressor reduces gth of the rotors. This effect

Why is a slide valve used in a compressor?

Note: Under the part load operation, the compression process starts after a certain delay. This results in energy saving which is shown as red coloured zone in the above figure. Hence the slide valve assists in capacity control of a compressor that results in energy saving too.

What is a semi-hermetically sealed twin screw refrigerant compressor?

This article focuses on a semi-hermetically sealed twin screw refrigerant compressor. In semi-hermetically sealed compressor, the motor and the compressor are enclosed in a bolted casing. Bolted casing helps in accessing the components inside the casing during a malfunction.
