Whenever the data included on the specification sheets conflicts with the provision of this general specification, the former shall govern.1.3.Compliance by the fan or blower manufacturer with the provisions of this specification does not relieve him of the responsibility of furnishing fans or blowers, their drivers and auxiliaries which are properly designed and mechanically suited to meet operating guarantees at the specified service conditions.2.0SCOPE OF SUPPLYAir fans or blowers shall be furnished suitable for outdoor installation. Each set shall include, but not limited to the following:2.1.Two sets of Fan (Blower) are installed in parallel to operate in turn outside the chamber of the storage tank. They periodically or emergently offer the sufficient air to replace the combustible gas possibly occurred inside the chamber.2.2.Two fans or blowers with motor drivers.2.3.Special tools for installation and maintenance (if required).3.0GENERAL REQUIREMENTS3.1.The equipment furnished shall be suitable for outdoor service in chemical plant environment.3.2.All equipment shall be designed for a continuous twenty-four hours per day operating cycle. General ruggedness to insure uninterrupted service is required throughout.3.3.Vendor shall submit drawings and documents as specified herein in the proposal after LPG 加氣站 設備、器材規範-3 日期98 年 02 月 26 日台灣中油股份有限公司風扇（鼓風機）規範 FAN (BLOWER ) GENERAL REQUIREMENT頁次第 3 頁共 11 頁receipt of purchase order.3.4.Vendor’s quotation shall include the coats of submission of drawings, data and documents as specified herein.3.5.All vendor drawings, documents, equipment nameplate information and instrumentation scales shall be in English or Chinese and in MKS units, except the nominal pipe (tubing) size and flange size can be British units.4.0MECHANICAL REQUIREMENTS4.1.Fan/blower, driver and all components shall be suitable for continuous full load duty under the specified operating conditions, and any prolonged cold stating condition. All parts of fan or blower driven equipment shall be safe for operation at the maximum load and torque capabilities of the driver. Equipment which must operate at its design limit in order to meet the specification and specification sheets is not acceptable.4.2.Fan or blower shall be constructed to operate safely under design conditions without undue strain, wear, heating or vibration.4.3.Fan or blower and driver shall be mounted in a shock-vibration isolation system.4.4.CasingThe casing of fan or blower shall be designed to withstand continuously the maximum pressure which can be developed by the fan or blower. Adequate provision shall be made in the design to permit proper expansion without distortion or binding, and for all other effects due to the temperature and characteristics of the fluid being compressed.4.5.Shaft and RotorThe shaft of each fan or blower shall be of adequate size and strength to withstand safely and continuously all stresses resulting from the weight to be supported, and from starting (including across the line starting), operating and temperature condition to which it will be subjected. The critical speed of the shaft shall be such as to provide a liberal margin of safety between such speed and the range of operating speeds of fan or blower. Adequate provision shall be made to prevent distortion, binding, excessive leakage or thrust due to either direct or differential expansion of the rotor parts.LPG 加氣站 設備、器材規範-3 日期98 年 02 月 26 日台灣中油股份有限公司風扇（鼓風機）規範 FAN (BLOWER ) GENERAL REQUIREMENT頁次第 4 頁共 11 頁4.6.Rotating AssemblyThe rotating assembly shall be designed such that the first critical speed is at least 25% of the maximum operating speed. The entire rotating assembly shall be both statically and dynamically balanced.4.7.。
