Give priority to electric power, shiping building, metallurgy, building materials, petrochemical industry, electromechanics, aquatic products processing, etc
重點發展電力、船舶修造、冶金、建材、石化、機電、水產品加工等產業。 -
Because the surface treatment processing adopts the high pressure water washing and the surface treatment needs not remove dust or special prepared ventilation equipment, and has no humidity requirement, which bring safe and reliable economic benefits to the anticorrosion protection of petrochemical industry
由於表面處理工藝採用了高壓水沖洗，並且表面處理過程中無須除塵，無須專門準備通風設備，且無濕度要求，為石化工業的防腐保護帶來了安全可靠的施工、無污染和可觀的經濟效益。 -
As one of four pillar materials following steel, timber, and cement, plastic has been widely applied to agriculture, building materials, packing, mechanical electronics, automobiles, traffic, domestic appliances, petrochemical industry and national defense. at present, there are about 34, 000 enterprises engaged in the plastic processing. early in 1998, the annual output of plastic products in china was about 15 million tons, only after the u. s. a, ranked the second in the world ; and the total output value of plastic products was about rmb 138 hundred million in china in the same year
塑料作為繼鋼材木材水泥之後的四大支柱材料之一，已經廣泛應用於農業建材包裝機械電子汽車交通家電石油化工和國防各個領域，目前我國從事塑料加工的企業約34萬多家， 1998年中國塑料製品的年產量約為1500萬噸，已僅次於美國，居世界第二位。 -
In the recent years, as the proportion of mechanic industry in nation economy increases, the requirement for safe operation of mechanic equipment is higher and higher. due to that all kinds of technology are progressively applied to mechanic equipment fault and diagnosis, such as signal processing, pattern recognition, etc., mechanical equipment fault and diagnosis technology has been developed rapidly all over the world. the reciprocating pump as a part of mechanic equipment field takes up very important station in production department, such as the petrochemical industry. because its applications are very widely, making researchs about its fault and diagnosis has important meaning. though people have already made out some researchs and obtained some research results, but the total diagnosis level is not still very high. based on former research results, according to the strong non - stationary characteristic of the pump valve signal of the reciprocating pump, this text introduces hilbert - huang transform ( abbreviated as hht ), and diagnosed the pump valve faults of the reciprocating pump well
雖然人們已對其開展了不少研究並取得了一些研究成果，但總的診斷水平還不是很高。本文在基於前人研究成果的基礎上，根據往復泵泵閥信號的強非平穩特性，引入了希爾伯特-黃變換（簡稱hht ） ，對往復泵泵閥較好地進行了診斷。往復泵由於其結構復雜，激勵源多，故其信號為強非平穩信號，對其進行故障特徵提取和診斷比較困難，所以本文主要研究了往復泵泵閥振動信號的特徵提取方法。 -
On the station in the high - tech beginning since our company founded, it devotes continuously to advanced processing technology of the polymer powder and polypropylene, which manufactured by selecting the special - purpose raw material that the international famous transnational petrochemical industry company produces
