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, 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, 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. 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. 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.
