Analysis of the influence of accumulator on the stability of liquid supply of emulsion pump station

For improving the stability of the liquid supply, the pulsation of pressure and flow, and the hydraulic impact in the operation of the emulsion pump station, a simulation model is established to analyze the impact of the relevant parameters of the accumulator on the stability of the system, such as the various configuration schemes of the accumulator station, and inflation pressure changing of the accumulator. An optimization method based on accumulator theory research and engineering practice is proposed to reduce noise and extending the service life of multiple components and promote safe and efficient production in coal mines. The results show that each pump is equipped with one 20 L accumulator in which the inflation pressure is about 70% of the system's working pressure. The emulsion pump station equipped with an accumulator station which is composed of eight accumulators in parallel, the volume of each accumulator is 63 L and the inflation pressure is 70%~80% of the system's working pressure. At this time, the stability of the emulsion pump station system is better.
