How to correctly install the explosion-proof heat resistance?

Users in the installation of explosion-proof heat resistance, in order to ensure the using quality of late, so we must be sure to pay attention to some problems. Usually, for the installation requirements of explosion-proof heat resistance has: is advantageous to the temperature measurement accuracy, safety and reliability, convenient maintenance, and shall not affect the equipment operation and production operations, etc. So, we are in the process of actual installation, how to grasp these points?

in fact, if you want to meet these requirements, so we choose the installation location, needs to be more careful. Below together to get to know the specific content. In order to make the measurement of thermal resistance and capable of achieving the full heat exchange between measured medium, you need to select the appropriate measuring point position, don't choose near the valve, or the position such as elbow and pipe.

in addition, in order to prevent causing more energy loss, as far as possible to reduce the error, we should also ensure that heat resistance with enough insertion depth. If is fluid temperature measuring pipe center, is the measuring end is inserted into the pipe center; And if the current body of pipe diameter is 200 mm, so should keep its insertion depth at 100 mm.

in addition, we also need special consideration to the work environment conditions, such as if it is to measure some of the high temperature and high pressure and high velocity, so we must as far as possible to reduce cases of fluid resistance, so this time can choose protection tube shallow way, or is the use of hot shell heat resistance. Usually, the inserting depth of the former shall not be less than 75 mm, the latter is a standard insert depth should be 100 mm.

of course, at the time of actual installation, there are many problems we need to consider, hope everyone can seriously and properly installed thermal resistance, so in the later use of time, not only can guarantee the use effect, but also can avoid a lot of trouble.
