Technical Field
The invention relates to a pulsation buffering technology of fluid conveying equipment, in particular to an S valve pump with a buffering function and a buffering method thereof, which are particularly suitable for conveying fluids such as concrete or mortar.
Background
The S valve pump is widely applied to fluid conveying of concrete, mortar and the like with solid aggregate due to good fluid passing performance, and has very reliable performance. The common S valve pump is generally composed of two working cylinders, one cylinder sucks slurry, the other cylinder discharges slurry, and double-cylinder alternate slurry discharge is realized through S valve switching. However, the S-pipe switching requires a certain time, so that pumping intermittent cutoff can be generated for a certain time during the switching period, so that the pipeline generates impact, and particularly, the pipeline cannot achieve ideal effects in some application occasions (such as concrete injection, mortar spraying and the like) which need continuous and uniform flow, and other various buffering methods adopted in the industry are difficult to achieve good effects on fluids (such as concrete, mortar and the like) which contain aggregates, have poor fluidity and are easy to solidify over time, and often pay huge cost for the fluids, so that the application field of the S-valve pump is greatly limited.
