Overview
In order to meet the requirements of production processes and energy conservation and emission reduction, improve working conditions, enhance economic benefits, and ensure the quality of thermal insulation engineering design, pump equipment is designed in accordance with the GB 50264-2013 standard.
This equipment is suitable for measuring the heat loss of thermal insulation materials on the outer surface of industrial equipment and pipelines with temperatures ranging from -196℃ to 850℃.
It is not applicable to equipment and pipelines with special requirements in nuclear energy, aviation and aerospace systems, as well as buildings, cold storage facilities and buried pipelines.
Instrument reference standard

GB 50264-2013 Code for Design of Thermal Insulation Engineering of Industrial Equipment and Pipelines
Temperature Control System
It is mainly composed of heating wires, iron plates, etc., and is heated by a temperature instrument. The maximum heating temperature in the temperature zone can reach up to 600 degrees Celsius
It can be used at 500 degrees Celsius for a long time
A total of 12 temperature collection channels are equipped. Among them, the heating temperature channel is a closed-loop control of the temperature zone, with 5 temperature monitoring points set. The remaining heat protection hot plate is equipped with 2 temperature monitoring points, and the cold surface is arranged with 5 temperature measurement points.
Pressurization System
It is mainly composed of cylinders. The required pressure value is achieved by fine-tuning the air pressure, and the current status is displayed in real time within the control system.
Cooling System
It is mainly composed of a chiller, thermocouples, etc. The chiller cools the heating part of the equipment. The thermocouple detects the temperature of the bottom surface. After the test is completed, when the temperature of the bottom surface is greater than 50℃, the system prompts "Turn on the chiller" to quickly cool the hot plate.
Working principle
The equipment is composed of a sample back temperature measurement plate, a constant temperature heating plate and a pressurization system. The sample back temperature measurement plate is equipped with five temperature sensors to measure the back temperature of the sample in real time. The constant temperature heating plate provides a stable high-temperature heat source, and the pressurization system supplies a stable pressure to the sample, ensuring the reliability of the test.
2. The equipment has two functions: measuring the thermal conductivity of insulating materials and the amount of heat loss. It first tests the thermal conductivity and then the amount of heat loss. Completed at the same workstation;
3. Calculate the heat loss:
Calculate the amount of heat loss in accordance with standard GB 50264-2013 5.4
