Product Specification

Product Show

The temperature sensor is made of enclosed stainless steel capillary tube with high precision. Used for automatic instrument signal tube, automatic instrument wire protection tube.

Closed end stainless steel capillary specifications

Closed-end stainless steel capillaries (also known as thermistor housings or thermocouple manifoles) provide excellent heat transfer for consistently accurate temperature measurements in a variety of industries.

Type of tubes manufactured:

Low round

Low flat

Low point

Low horn

1. The blockage of the thin tube leads to the good operation of the indoor and outdoor machines without cold air, but no cold air blowing out. Detection and judgment: after removing the shell of the indoor unit, the evaporator is not good. After removing the shell of the outdoor unit, the capillary at the outlet of the filter is found to be frosted, indicating that the capillary is blocked inside.

2, maintenance method: release refrigerant, gas welding under the capillary, with fine steel wire through the blockage, with 95% anhydrous alcohol cleaning capillary inner diameter. And then reweld it. After pressure test, leak detection, add refrigerant 0.5mpa 'air conditioner to restore refrigeration.

Experience and experience: the fault feature of capillary blockage is that the air conditioner does not refrigerate and there is frost on the capillary. The phenomenon is similar to the system "fluorine deficiency", you can try to add some R22 refrigerant for the air conditioner, if filled with fluorine, frost can recede, it is "fluorine deficiency fault", if refrigerant is added, there is still frost, the fault is capillary blockage.
