JB/T 53285-1999

Manufacturers of power station boiler centrifugal forced draft and induced draft fans use this standard to classify product quality into grades (qualified, first-class, superior) and to conduct tests and inspections accordingly. Quality supervision authorities also rely on this standard for grade evaluation and sampling inspection of these fans. This standard is important because it ensures consistent performance, reliability, and service life of forced draft and induced draft fans, which are critical for the safe and efficient operation of thermal power stations.

电站锅炉离心送风机和引风机的制造商使用本标准来划分产品质量等级（合格品、一等品、优等品），并依据标准中的试验和检验方法进行产品检测。质量监督部门也依据本标准对产品进行等级评定和抽样检查。该标准确保了送、引风机的性能、可靠性和寿命达到统一要求，对火力发电站的安全高效运行至关重要。

This standard JB/T 53285-1999 specifies the product quality grading requirements for power station boiler centrifugal forced draft fans and induced draft fans, classifying products into three grades: qualified, first-class, and superior. It details assessment indicators for each grade regarding efficiency, pressure, vibration, balance, impeller service life, and first major overhaul period, and prescribes test and inspection methods (e.g., efficiency testing per GB/T 1236, balance testing per JB/T 9101). Additionally, the standard provides sampling plans and evaluation methods for both individual and batch products. It applies to centrifugal forced draft and induced draft fans for steam boilers in thermal power stations, serving as a basis for quality control and grade certification.

本标准JB/T 53285-1999规定了电站锅炉离心送风机和引风机的产品质量分等要求，将产品分为合格品、一等品和优等品三个等级。标准详细列出了各等级在效率、压力、振动、平衡、叶轮寿命和首次大修期等方面的考核指标，并规定了试验与检验方法（如按GB/T 1236测效率、按JB/T 9101测平衡等）。此外，标准还给出了抽样方案和等级评定方法，包括单台和批量产品的评定规则。该标准适用于火力发电站蒸汽锅炉的离心送、引风机，为产品质量控制和等级认证提供了依据。
