The patent-the-art unique to the preparation to replace the traditional areas of manufacturing technology behind the production process so that the pump manufacturing, repair industry to a new level. Preparation of a new technology: pollution-free products in strengthening the implementation of the low temperature, the main components of the plunger need not strengthen the abrasive surface, the high level of accuracy. The science of matching plunger and pump barrel, ball valves and valve seats between the hardness of the relationship between the ratio of the raw materials and fuel fell to the lowest point, that is, performance products, high temperature and high temperature corrosion and wear, increased the oil-well pump in a different environment, oil and gas regions in the mixed layer effect , To extend the service life, so that the overall quality and pump efficiency improved. This technology will be a number of traditional technology or a similar way to implement integrated into one, which is available in the field with the same technology can not be completed.
