Problems solved by technology

However, when used in some machining sites, the vibration that may be caused by processing will affect the service life of the thermocouple, because the protection tube is poor in brittleness and elasticity, and its mechanical properties cannot meet the requirements. It may be broken by vibration or impact. Unable to meet the requirements of protecting the temperature measurement circuit

Abstract

The invention discloses a thermocouple temperature measuring circuit protection tube. The thermocouple temperature measuring circuit protection tube is prepared from the following raw materials in parts by weight: 60 to 70 parts of main material, 1 to 2 parts of 1,1-bi-(tert-butyl peroxide)cyclohexane, 2 to 6 parts of multiwalled carbon nanotube, 2 to 4 parts of weathered coal, 1 to 5 parts of carbon fiber, 4 to 10 parts of vermiculite powder, 1 to 2 parts of isostearic acid isopropyl titanate, 5 to 12 parts of bamboo fiber compound, 1.5 to 2.5 parts of plasticizer, 1 to 2 parts of antistaticagent, 0.4 to 0.6 part of compatibilizer and 1 to 2 parts of antiaging agent. The thermocouple temperature measuring circuit protection tube disclosed by the invention has high elasticity and superiormechanical performance, is not liable to crack, and has extremely high thermal stability; the thermocouple temperature measuring circuit protection tube is buffered under vibration, so that a core body in the protection tube is prevented from being damaged under severe vibration.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to a thermocouple temperature measuring line protection tube. Background technique [0002] A thermocouple is a temperature-sensing element that converts a temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument. Thermocouples generally have a protection tube extending into the medium to be measured and a core located in the protection tube. There are temperature measurement lines inside that need to be isolated from the outside. However, when used in some machining sites, the vibration that may be caused by processing will affect the service life of the thermocouple, because the protection tube is poor in brittleness and elasticity, and its mechanical properties cannot meet the requirements. It may be broken by vibration or impact. It cannot meet the requirements of protecting ...
