“…18 Recently, the orthogonal optimization method has been used as a solution to the multiobjective problem of pump optimization design. Cui et al 19 explored the loss and cogging torque generated during the working process of a permanent magnet synchronous motor. Orthogonal optimization was performed along with FEM analysis for the pumping unit, and the results showed that Taguchi's method was an efficient and effective approach.…”

Tubular pumps are widely used in irrigation and water conveyance projects. However, the operating head of most of these pumps is low, and only a few studies have focused on the design of an efficient tubular pump with a head more than 5 m, which is common in long-distance water supply projects. This work aims to improve the operating head and efficiency of tubular pumps while maintaining a low shaft power. The multi-objective orthogonal optimization method was used to determine the critical parameters of the tubular pump, i.e., blade number, airfoil, blade thickness and guide vane distance, and nine design schemes were selected. Next, by using computational fluid dynamics (CFD), a 3D model of the tubular pumps under different schemes was established, and the results were compared. Subsequently, the range method and weighted matrix method were utilized to find the optimized scheme. In addition, an experimental investigation was performed to verify the simulation and the performance of the designed tubular pump. The results indicated that the optimized scheme improved the operating head to 6.9 m with higher efficiency of 84.2% and a lower shaft power of 27.7 kW. The modeling results were in agreement with the experimental measurements, and the designed tubular pump had a wide range of high-efficiency zones.

“…Figure 1 shows that the downhole direct-drive electric drilling tool powered by a drilling permanent magnet synchronous motor (DPMSM) is the core device in a deepwater subsea coiled tubing drilling rig [7]. Compared with a traditional downhole electric drilling tool, the intermediate reducer is eliminated to realize direct-drive drilling, which reduces the fault point and can effectively improve the reliability of the system; at the same time, permanent magnet synchronous motors (PMSMs) replace electric excitation with the direct excitation of permanent magnets, which avoids excitation loss compared with three-phase asynchronous motors and improves the efficiency of the system [8]. Direct-drive drilling with a PMSM is a new technology.…”

The pole–slot combination is an important factor affecting the cogging and electromagnetic characteristics of a permanent magnet synchronous motor. Taking a 95 kW direct-drive drilling permanent magnet synchronous motor (DPMSM) as an example, this paper presents an analytical model of the motor’s magnetic field based on the ideas of segmental discretization and magnetic vector potential, and considers a case in which the stator slot type is a closed slot. The Laplace or Poisson equations of each solution domain are solved using the separation of variables method, and the undetermined coefficients in the general solution are obtained by combining the boundary or interface conditions, thus completing the construction of the analytical model of the motor. The accuracy of this analytical model is verified with the finite element method (FEM). Based on the analytical model, the effects of the different pole–slot combinations on the electromagnetic performance, such as the air-gap flux density, back-EMF, cogging torque, output torque, etc., are investigated, and a reasonable choice of pole–slot combinations is made. The test results of the prototype are basically consistent with the predictions of the analytical model. The analytical model serves as an accurate and efficient calculation tool for the design of DPMSMs.

“…Conventional beam pumping units are widely used in oilfields due to their advantages of simple structure, high reliability, and convenient maintenance [1][2][3]. However, the structural characteristics of conventional beam pumping units determine their poor balance effect, large net torque fluctuation of the crank output shaft and existence of negative torque, low efficiency, and high energy consumption [4][5][6][7]. The large net torque fluctuation of the crank output shaft and the existence of negative torque are the decisive factors leading to its low efficiency and high energy consumption [8,9].…”

The large fluctuation of net torque and the existence of negative torque on the crank output shaft of the beam pumping unit are the decisive factors leading to its low efficiency and high energy consumption. The conventional pumping unit CYJ10-4.2-53HF was selected as the study object on the basis of the fixed shaft secondary balance principle and the positive torque modulation scheme was first proposed according to the following secondary balance principle based on the linkage. The kinematics analysis of the suspension point and the secondary incremental velocity mechanism were carried out using the theory of rigid body plane kinematics. The force analysis of each moving part of the pumping unit was carried out, the net torque expression of the crank output shaft was obtained, and an example calculation was performed. The positive torque beam pumping unit was developed and tested in a field test. The tests showed that the positive torque beam pumping unit was able to fully realize positive torque operation under field well conditions, with a power saving rate of 23.73% and a 14.5% increase in system efficiency, and that the reliability of the pumping unit meets the requirements for field application.
