“…Another approach is to use machine learning methods. For example, failure mode and effect analysis (FMEA) [12][13], neural network (NN) [14], support vector machine (SVM) [15][16], Gaussian mixed model (GMM) [17] and other fusion algorithms [18][19][20] are used for fault diagnosis. Machine learning methods require a large amount of data to train the model to get accurate results and therefore consume a lot of time; while direct analysis by spectrum only requires real-time data measurement and professional analysis to determine the cause of faults.…”

The frequency domain analysis method was used to analyze the changes of the vertical spectrum of the non-driving end, the vertical spectrum of the driving end, the horizontal spectrum of the non-driving end and the horizontal spectrum of the driving end of the pump unit under different operating conditions. And the relationship between the vibration value of the motor and the temperature was summarized. The results show that the motor vibration signal components are mainly fundamental frequency and second harmonic, and there are third harmonic components; The motor vibration value increases with the increase of bearing bush temperature and winding temperature. The reason for the failure of the pump unit is that the motor heat is too large, which leads to the high temperature of the motor bearing bush and winding, and the rotor appears bending and expanding deformation, which leads to the increase of the vibration value of the motor. The results show that the frequency domain analysis method has a good application effect in vibration analysis and fault diagnosis of oil transfer pump unit.

No matter in metal mines or coal mines, an emulsion pump station has a wide range of application market and can play an important role. In this paper, the frequency conversion constant pressure control system of the mine emulsion pump station is taken as the research object. The two kinds of water-based drawing fluids used are dispersed drawing fluid and emulsion drawing fluid. After the intelligent level of the equipment reaches a very high level, an environmentally friendly, safe, and efficient Internet of Things technology system will be added. Combined with 3D laser scanning technology based on self-scanning of road contours, the blast method is input to the terminals of the emulsion pump station for automatic blast hole positioning and semiautomation of the emulsion pump station. Combined with 5 g communication and other intelligent key technologies, it realizes high-end functions such as fault self-diagnosis, remote operation, and remote monitoring of the emulsion pump station and rock drill, which can be called full intelligent stage. The results show that the initial friction coefficient of drawing fluid A lubrication is 0.21, and then, with the extension of time, the friction coefficient gradually decreases to 0.14. The initial friction coefficient of drawing fluid B is 0.22, then it decreases rapidly to 0.13, then it is stable at 0.17, and then it remains basically unchanged. When the temperature is 55°C, the initial friction coefficient is 0.16 and then decreases to 0.12. Therefore, the frequency conversion constant pressure control system of the mine emulsion pump station should be selected according to the environment and application scenarios.

“…Considering the complexity of the structure of the axial piston pump and the types of fault that could occur in it, as a kind of multiobjective analysis method, the AHP can satisfy the requirements of performance assessment and failure prediction for the pump. Yang et al proposed a multiparameter evaluation method for oil pump unit, which used Failure Mode and Effect Analysis to select the evaluation indexes, AHP to calculate the weights of the indexes, and fuzzy comprehensive evaluation to assess the state of the pump unit [1]. Lin et al proposed a failure prediction method for pump in aircraft based on fuzzy comprehensive evaluation and AHP [2].…”

The axial piston pump is an important industrial power element, and its performance directly affects the operation of the system. However, owing to its complex structure and harsh operational environment, the actual operational performance of the axial piston pump is difficult to be assessed accurately, which makes ensuring the normal operation of the hydraulic system difficult. To improve the evaluation method for an axial piston pump, a comprehensive performance evaluation system was proposed based on analytic hierarchy process (AHP), which could assess the performance of an axial piston pump on the basis of theoretical analysis, test, operator interaction, and application. Considering a model of load-sensitive axial piston pump with good operability as an example, the model development and simulation of the pump were carried out based on AMESim and the pump was tested using a developed performance test bed for axial piston pump. The weights of factors in the evaluation system were determined on the basis of the simulation results, analyses, and calculation. The above results were used to comprehensively analyze the tested pump and design a set of comprehensive performance evaluation software. The evaluation result was nearly identical to the actual usage, which verified the feasibility of the designed evaluation system.
