Hot air circulation oven quality appraisal

hot air circulation oven is a heat treatment equipment widely used in industry and laboratories. It can be used for drying, curing, heat treatment, testing and other applications.
hot air circulation oven generally consists of shell, insulation layer, heating system, temperature control system, ventilation system, sensors, etc. The outer shell is made of high-quality steel plates, and the interior is lined with high-temperature resistant materials. Thermal insulation is used to reduce thermal energy loss. Heating systems generally use electric heaters, but can also be steam or other heat sources. The temperature control system is used to accurately control the temperature in the furnace. The ventilation system provides air convection and ensures even temperature distribution. Sensors are used to monitor and feedback temperature information.
In the case of hot air circulation oven quality appraisal, Zhongke Testing can provide hot air circulation oven quality appraisal services.

hot air circulation oven can be divided according to industry: special oven for the electronic industry, special oven for the instrumentation industry, special oven for the plastic and rubber industry, special oven for the electrical equipment industry, special oven for the electroplating industry, special oven for the printing industry, special oven for the glasses industry, special oven for the pharmaceutical industry, special oven for the textile printing and dyeing industry, special oven for the machinery industry, special oven for the synthetic fiber industry, special oven for the wood industry, special oven for friction materials, etc.

A company purchased a certain model of hot air circulation oven from Company B, which was responsible for the installation. In the sales contract, supplementary agreement and attachments signed by both parties at the time of purchase, the quality requirements and quality guarantees of the purchased products were clearly agreed upon. The technical parameters, materials, product structure, specific configuration and origin of the oven involved were also agreed upon in detail.
One day, Company A smoldered when using a hot air circulation oven to dry the Sanitary Tablet granules, causing the oven and Sanitary Tablet granules to burn down. Company A sued Company B for compensation, claiming that the hot air circulation oven involved had product quality problems that caused smoldering.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" in the hot air circulation oven involved in the case.
identification and analysis results: The
identification and analysis expert group discussed the relevant information and on-site investigation of the hot air circulation oven involved in the case and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions: HTMLTAGTOKE The hot air circulation oven involved in the N5 case did not have a ring alarm, which did not comply with the provisions of Article 2, Article 8 of the "ZDF-8 Low Temperature Vacuum Oven"; it had certain quality defects; the lack of a ring alarm was not the direct cause of burning the oven, but if there had been a ring alarm or other control response, it might not have caused the burnout accident.
The hot air circulation oven involved in the case will not automatically cut off the electric heating after the fan stops running abnormally; there are certain quality defects; the fan stops running abnormally and the electric heating is not cut off, which may cause the oven to burn out, but it is not the only reason for the oven burning down.
