Studying the movement characteristics of the coalmine emulsion pump valve is of great significance for optimizing the dynamic response characteristics of the pump valve, reducing the hysteresis effect, and improving the volumetric efficiency. This article combines the Internet of Things (IoT) and cellular automata techniques to investigate the movement characteristics of the valve of the emulsion pump. Based on Adolf’s exact differential equation and Runge–Kutta iterative method, the movement displacement and movement of the pump valve spool speed curve are computed using Scilab software. We employ cellular automata and AMESim to establish the hydraulic system model of emulsion pump and analyze the movement characteristics of pump valve movement displacement, speed, stability, and closing hysteresis through simulation. Finally, the IoT techniques and a test device are used to evaluate the movement displacement of the pump valve. The experimental results verify the feasibility of using the proposed method to study the pump valve motion characteristics, greatly reduce the cost of testing and parameterized design, and contribute to the development of highly reliable and efficient emulsion pump valves.

The relief valve is an important control and overload protection component of the emulsion pumping station. Its performance will affect the overall performance of the emulsion pumping station and the stable and intelligent control of the working surface. However, the research on high pressure and large flow relief valve for mine emulsion pumping station is still inadequate. In order to meet the requirements of emulsion pump station for large flow sensitivity, stability, reliability, and remote intelligent control of overflow valve, this paper uses the digital control method to establish the mathematical model of the relief valve and uses the software such as AMESim to its dynamic characteristics. The simulation results show that the structural parameters such as spool quality, damping hole, and spring stiffness have an effect on the working characteristics of the relief valve. It also provides reference for the intelligent control research of the large flow relief valve for the emulsion pumping station.

“…For the design of compressors, the valve dynamics need to be considered as the efficiency of the gas suction and gas discharge is significantly influenced determined by the movement of compressor valves. 28 Compressor valves are featured with simple and inexpensive designs, which are pressure actuated and automatically adapted to the operating. 29 The suction and discharge gas flow can be controlled through the optimal design of the self-acting valves in the compressor.…”

Summary The ionic liquid compressor is regarded as the most promising compression technology for the hydrogen refuelling station due to the combined application of ionic liquid and the hydraulic driving system. However, the design, mathematical and experimental investigations of the ionic compressor are still absent from the open literature. This paper proposed a new structure design and the design methodology of the ionic liquid compressor. The mathematical modelling considering the valve dynamics was provided for simulating the thermodynamic process, which was verified by the experimental data. The results showed that the delayed closing of the discharge valve would take place due to a high or low stiffness of the valve. The increase in the stiffness alleviated the rebound issue of the suction valve. An increase in the stroke to diameter ratio could solve the rebound issue of the discharge valve. A low or high trajectory coefficient would cause an intense rebound during the closing procedure of the discharge valve. The designed results of the main parameters of the compressor based on the simulation were the suction valve stiffness of 100 N/m, the discharge valve stiffness of 500 N/m, the stroke to diameter ratio of 1.0, and the trajectory coefficient of 0.125 under the given design condition.
