In October 2014, Jiekai received feedback from customers on the use of 2500-type, 4 "plunger diameter hydraulic end products, confirming that the hydraulic end service life of the fracturing pumps produced by our company can reach at least 380 hours, which marks The performance of Jiekai products has reached a new level. Due to the harsh environment of drilling and mining, the hydraulic end is subject to high fatigue loads and medium corrosion, grinding and erosion, and is a vulnerable part of the fracturing pump . At present, the average service life of most hydraulic ends in China is about 230 hours, and the service life of Jiekai products has been maintained at about 235 hours. With the increasing demand for fracturing pumps in recent years, and their longer working hours According to the requirements, Jiekai Technical Chief Engineer and his technical team continuously study the production process and metal properties, and finally find that a special technical treatment can increase the service life of the product, so that our products can reach the domestic priority level in this regard. , We are more firm in the future development, Jie Kai can develop better and higher quality products confidence.
