【産業上の利用分野】本発明は、水用のポンプに関し、
送水流量をネジ調整によりポンプ自体で変える事の出来

的なので調整が簡単なものではないと思われる。2. Description of the Related Art In particular, in the case of a water absorption pump for a well, most of the time, a pump larger than the target water amount is attached and a part of the flowing water is discarded to adjust the flow rate. There is also a pump that adjusts the flow rate by changing the number of rotations with some inverters.
The power change due to the rotational change of the motor is large, and the flow rate change due to the rotational change is not linear but curvilinear, so that it is not easy to adjust.

【発明が解決しようとする課題】一般のポンプにおいて
は、ポンプ自体による流量調整は出来ず、行うとすれば
流量に合ったポンプを使い分けるか流水の一部を捨てて
調整するしかなかった事にある。In general pumps, the flow rate cannot be adjusted by the pump itself, and if it is done, either the pump suitable for the flow rate must be used properly or part of the running water must be discarded to make the adjustment. is there.
