The influence of capillary tube length on refrigeration system parameters and troubleshooting

The capillary tube generally refers to a slender copper tube with an inner diameter of 0.4~2.0mm. As the throttling mechanism of the refrigeration system, the capillary tube is the simplest one. Because of its low price and flexible selection, it is widely used in small refrigeration devices.

Ways to reduce bearing noise

Ways to reduce bearing noise (1) Method of using chemical additives Adding certain chemical additives to the bearing lubricant can reduce bearing noise. For example, a low-noise grease containing noise-reducing additives produced by a factory in Tianjin can reduce bearing noise by 3.9-9.2dB from the original basis. , Suitable for use in miniature or small bearings.

What factors affect the displacement of centrifugal compressors

1) The air filter is blocked or the resistance increases, causing the suction pressure of the compressor to decrease. When the outlet pressure is constant, the compressor pressure ratio is increased. According to the performance curve of the compressor, when the pressure ratio increases, the displacement will decrease;
