The main reason for high and low temperature is that there is a backlash between the disconnection temperature and the reconnection temperature of the thermostat. The higher the backlash, the lower the backlash. Therefore, to improve the thermostat to reduce the backlash is to reduce the difference between the disconnection temperature and the reconnection temperature.

So how to improve it, how to make the temperature difference smaller? Really there is no such controller as the small sun. There are high and low-grade heating pipes that are used now. As soon as they are connected, they are heated rapidly. They will be disconnected by 200 degrees, and the contactor will snap and jump.

Answer: Temperature controllers to adjust the temperature difference can only find manufacturers, manufacturers have ways. Are you going to make an electric heater? Why do you always jump? That's because the power of the heat pipe is too big to dissipate heat. Large heating platform manufacturers reduce the power of the heat pipe or increase the speed or area of heat dissipation, so that the heat is close to the heat dissipation, so that it won't jump. They can also make a low-grade switch and connect a high-current diode, so that the power can be achieved. To cut it in half.

Single-ended heating tube

There are several types of heating pipes, such as single-end heating pipes, ordinary L-type single-end heating pipes, baffle type single-end heating pipes and threaded single-end heating pipes.

(1) The common single-end heating pipe refers to the heating pipe without baffle, thread and other fixed ways. Its installation method is as follows: directly installed on the bracket; after drilling, fixed on the heating pipe with copper or other metal sheets (similar to baffle electric heating pipe); some people use welding to fix the heating pipe.

(2) L-type single-head heating tube can be directly inserted into the general environment for use. Installation and fixing according to installation instructions do not require special fixing.

(3) The baffle heating tube can be directly used or welded and fixed on the base of the baffle.

(4) Installation of single-ended pipe and threaded spiral heating pipe are usually threaded for heating liquid where repairs are needed. Of course, there are strict requirements for sealing protection, which can also be welded on the original basis.

3.U-type heating tube, flange heating tube and fin heating tube

U-shaped heating pipes are usually installed with fasteners, usually directly with fasteners, while heating pipes without fasteners are usually installed with brackets or welded.

Flange electric heat pipe literally means to install and fix according to the installation method of flange. Flange installation can generally be divided into connection flange (bolt connection) and welding flange. In the case of low pressure or low sealing requirement, flange connection can be adopted, and metal gaskets can be installed and fixed by bolts through several bolt holes of original or post-treatment; in the case of high pressure or low pressure flange with large diameter, welding flange should be installed and fixed by welding.

It can be said that the basic double-ended heating pipe needs to be installed and can be used for fastener installation.
