kaksiruuvipumput
kaksiruuvipumput is the Finnish term for two-stroke piston pumps, a class of reciprocating pumps that use two cylinders to provide continuous forward flow. The pump operates on a four‑stroke cycle, but each cylinder completes only two strokes (a suction and a discharge) before the next cylinder takes over, allowing both cylinders to be in opposite phases. This arrangement eliminates the dead time that single‑cylinder pumps experience, resulting in smoother output and higher efficiency at lower speeds.
The design of kaksiruuvipumput typically includes a crankshaft that drives the pistons, a phase‑shifted valve system
Common uses include hydraulic tools, small mobile generators, and low‑to‐mid‑pressure fluid delivery systems such as irrigation
Compared with single‑cylinder reciprocating pumps, kaksiruuvipumput offer higher throughput, lower vibration, and improved start‑up performance; however,
