一、概况一般压力表是测压仪表中量大面广的品种。全国九十多个压力仪表生产厂有70％以上的厂家生产一般压力表,根据33个主要生产厂的统计,72年一般压力表产量约100万台,占生产总量的60％。一般压力表广泛使用在钢、电、煤、化、油等基础工业的大、中、小型企业中。但是,一般压力表的“三化”(标准化、系列化、通用化)程度较低。不同生产厂生产的一种产品在结构、型号、名称、外形尺寸和
First, the overview General pressure gauge is a large variety of manometer in the wide range of instruments. More than 70% of the pressure gauge manufacturing plants in the country produce more than 70% of the total pressure gauges. According to the statistics of 33 major manufacturers, the general gauge production in 72 years is about 1 million units, accounting for 60% of the total output. General pressure gauge is widely used in steel, electricity, coal, chemical, oil and other basic industries of large, medium and small enterprises. However, the general “pressure” of the “three” (standardization, serialization, generalization) to a lesser extent.
