First, with the expansion of constant filling hydraulic coupling range of applications, a variety of reasons can rise sharply coupling working oil temperature thermostat switch coupling purposes, resulting in thermal coupling mounted on the protective plug fusible alloy melts The injector protection. However, this protective effect may occur frequently in certain circumstances, not only affects the coupling to work properly, but caused serious environmental pollution, in order to solve the problem injector temperature, we use this thermostat switch to temperature causes the switch action rise to a certain degree, so as to realize the alarm or motor power, the same to protect the motor and coupling purposes. After 120 ℃ (or according to user requirements) Third, note the fluid coupling temperature alarm: Second, the technical performance of electrical parameters: 0.8A 380VAC 0.14A 220VDC limit switch Model: LXK3-20S / L limit switch alarm oil When the re-use by the staff will need to unscrew the plug 6, put a new plug, while the lever 4 reset. Alarm form, the user can according to their own needs, then light or alarm bell. Users can install the actual situation of the scene based on coupling, choose the appropriate installation thermostat switch position, and make the corresponding bracket.
