Abstract

PURPOSE:To eliminate wasteful energy by providing a sensor for detecting pressure in a pump device approximately linearly, an external terminal for inputting suction height, and an operation controller for determining automatically pushing up height according to the suction height. CONSTITUTION:When the suction height with a pump device substantially installed is Hs1, pump running start pressure Hon1 is set in a range of no- discharge operation pressure 'Htmax - Hs1', that is, discharge pressure Hd1 under a no-discharge condition automatically by setting an external terminal inside a control box 12 to Hsi so that pump operation stop pressure Hoff1 is set to a higher value than Hon1. When the suction height is set to Hs2 which is smaller by H, it is considered that a pump position is shifted to Hs2, and Hon2 and Hoff2 become the values which are higher than Hon1 and Hoff1 by H. By switching the external terminal, the suction height according to an actual condition is inputted, and by setting the pushing up height automatically, pump performance can be exhibited sufficiently.

Pressure slightly lower than H_O_F_F: When H_O_F_F is reached, a pump head operation stop command is output; Pressure slightly lower than H_O_F_F; When Hp_O_F_F is reached, a parallel operation cancellation command is output; Pressure slightly lower than Hp_O_F_F: When H_O_N is reached. A pump device comprising: an operation control device that outputs a pump operation start command, and further outputs a parallel operation start command when a value slightly smaller than H_O_N; Hp_O_N is reached.
