Dobavitelj termostata kapilarne cevi na Kitajskem

A capillary tube thermostat is a mechanical or electronic device that controls equipment operation by sensing temperature changes through a capillary tube and a temperature-sensing bulb. Key information follows:

Operating Principle

A sealed system consists of a temperature-sensing bulb, kapilarna cev, and a bellows/diaphragm, filled with a working fluid (such as Freon). After the temperature-sensing bulb detects changes in ambient temperature, the working fluid pressure is transmitted through the capillary tube to the actuator, actuating the switch contacts. Some models use a microswitch to react to fluid expansion for control, with a temperature range of 0-500°C.

Main Types

Mechanical: Models such as the WJA-400 and KTS-300, with knob adjustment, are suitable for equipment such as electric water heaters and deep fryers, z območjem nastavitve običajno med 30-400 °C.

Elektronski: Modeli, kot je Honeywell H6062A1000, imajo digitalni zaslon in se uporabljajo za natančen nadzor temperature.

Scenariji uporabe

Gospodinjski aparati: Kotli za vodo, električne pečice, klimatske naprave, itd.

Industrijske aplikacije: Visokonapetostne in nizkonapetostne stikalne naprave, sevalni klimatski sistemi s kapilarno cevjo (kot so trikonstantni sistemi).

Parametri in lastnosti

Dolžine kapilarne cevi se običajno gibljejo od 0.7 do 1.8 metrov.

Konfiguracije stikov vključujejo SPST (enopolni, enometni), z nazivno napetostjo do 230V.

Nabavne reference

Blagovne znamke, kot sta YAXUN in Yuduo, so na voljo na platformah, kot sta JD.com in Taobao. Cene se gibljejo od $1 do $50, odvisno od temperaturnega območja in števila zatičev (npr., 2-žebljiček vs. 3-zatič).
