国内压力测控技术发展的几个方向?

1、压力级别。逐步从低压向高压发展。随着国内石油工业和航空工业的快速发展,高压设备的需求越来越多,冷媒体增压泵工作压力从35MPa已经提升到150MPa,这样就对压力测试设备的要求就更高了,目前最大的测试压力已经达到1050MPa。国产品牌支持高压已经不是问题。
1. Pressure level. Gradually from low pressure to high pressure. With the rapid development of domestic oil industry and aviation industry, the demand for high pressure equipment is more and more, the working pressure of the cold media booster pump has been raised from 35MPa to 150MPa, so that the pressure testing equipment is more demanding, and the maximum test pressure has reached 1050MPa. It is no longer a problem for domestic brands to support high pressure.
2、性能品质。中国工业发展基础雄厚,国内到目前已形成从仪表、管路、接头、控制阀、增压泵到配件为一体的完整产业链。国内厂家初具规模,拥有足够的资金来提高设备加工能力和技术水平,产品质量相应得到有效成倍的提高,性能更加稳定,品质更加可靠。加上各自的市场份额越来越大,在降低制造成本的同时,使得国产品牌在与进口品牌的竞争中已初步彰显品牌优势。
2, performance quality. China's industrial development base is strong. So far, a complete industrial chain has been formed from instrumentation, pipelines, joints, control valves, booster pumps to fittings. Domestic manufacturers have begun to take shape and have sufficient funds to improve the processing capacity and technical level of the equipment. The quality of the products has been improved effectively, the performance is more stable, and the quality is more reliable. With the increasing market share, the manufacturing cost is reduced, and the brand advantage of the domestic brand has been preliminarily highlighted in the competition with the imported brands.
3、价格优势。进口元件价格昂贵,单单一个70Mpa的气动增压泵动辄就要几万元,而一套石油工艺用的检测设备更是几百万。随着国产品牌的十几年来不断完善,技术的不断更新进步,产品质量技术堪比达国家水平,而价格只有进口产品的1/5-1/3。

3, price advantage. Imported components are expensive, and a single 70Mpa pneumatic booster pump will often cost tens of thousands of yuan, while a set of oil processing equipment is millions. With the continuous improvement of the domestic brand in more than ten years and the continuous improvement of technology, the quality technology of the product has reached the level of the national level, and the price is only 1/5-1/3 of the imported products.
4、售后服务。作为功耗产品,在使用过程中难免会出现问题。进口产品价格昂贵,出现质量问题国内进口厂家没有相关的成熟技术支持,难以售后服务。维修费用昂贵,拿一个进口气动增压泵来说,维修费用几近新的气动增压泵的成本价格。维修周期超长,少则也要三个月。而国产增压泵性能稳定,质量有保证,售后服务完善更及时。多数厂家推出一年质保、终身服务的售后理念。
4. After service. As a power consumption product, there will be problems in the process of using. Imported products are expensive and quality problems. Domestic importing manufacturers have no mature technology support, so they are hard to sell after service. The maintenance cost is very high, and the cost of maintenance is nearly the cost price of the new pneumatic booster pump with an imported pneumatic booster pump. The maintenance cycle is too long, but it will take three months. The domestic booster pump has stable performance, guaranteed quality and perfect after-sales service. Most manufacturers offer a one year warranty and lifetime service aftermarket concept.
5、测控技术。逐步由单一测量向测量与控制同步的技术发展。随着气动增压泵、气控阀、伺服阀、高速采集卡和测控软件的大量使用,压力测试设备逐步从手动操作压力表测量到计算机伺服控制测量发展。测试工艺流程、压力的控制精度和压力的测量精度已经大大提高了。
5. Measurement and control technology. Technology development is gradually changing from single measurement to synchronous measurement and control. With the use of pneumatic booster pump, gas control valve, servo valve, high-speed acquisition card and measurement and control software, the pressure testing equipment is gradually measured from manual operation pressure meter to computer servo control measurement. The accuracy of the test process, pressure control and pressure measurement has been greatly improved.
