Service life prediction method and device for sand pump of fracturing blender truck

Abstract

The invention relates to the technical field of sand pumps, in particular to a service life prediction method and device for a sand pump of a fracturing blender truck. The service life prediction method for the sand pump of the fracturing blender truck comprises: inputting real-time working condition data of the sand pump into a preset sand pump PWM value prediction model, and obtaining a real-time prediction PWM value of the sand pump; obtaining indexes of the sand pump according to the real-time predicted PWM value of the sand pump; and determining the service life of the sand pump according to the indexes of the sand pump. By inputting the real-time working condition data of the sand pump into the PWM value prediction model, the real-time prediction PWM value of the sand pump is obtained, and the obtaining process of the real-time prediction PWM value of the sand pump is simplified. An index of the sand pump is calculated according to the real-time predicted PWM value of the sand pump, and the service life of the sand pump is determined according to the index of the sand pump. Therefore, in the operation process of the fracturing blender truck, the working condition data of the sand pump are detected in real time, the service life of the sand pump can be accurately determined, and constructors can arrange work conveniently and complete operation on time conveniently.

Description

technical field [0001] The invention relates to the technical field of sand pumps, in particular to a life prediction method and device for a sand pump of a sand mixer. Background technique [0002] The sand pump is the core component of the sand mixer. The sand pump is the main conveying equipment used to transport the liquid medium with solid impurities. It is easily impacted by high-speed moving sand and gravel, causing wear and tear. Severe wear of the sand pump will cause the performance of the sand pump to decline or even fail to work. [0003] In the current sand mixer equipment, the sand pump will only be replaced when it completely fails and hinders normal construction. At the same time, the wear and tear of the sand pump will be found and repaired when the sand pump is manually disassembled and inspected regularly. When the sand pump fails, the sand pump may not be able to be effectively repaired due to greater wear and tear during use, resulting in greater damage...

When the sand pump fails, the sand pump may not be able to be effectively repaired due to greater wear and tear during use, resulting in greater damage

However, when the sand pump is manually disassembled and inspected periodically, when the interval is long, the wear of the sand pump cannot be monitored in time; when the interval is short, the sand pump needs to be disassembled and assembled every time, which takes a long time. Not conducive to the continuous use of sand pumps
