Title: Apparatus for automatically holding impeller gap
Inventor: TAKAHASHI HIROSHI
IPC: F04D29/16
Filed: 1982-03-31
Abstract: PURPOSE:To prevent the drop of the efficiency of the operation of a pump due to excessive increasing of the impeller gap and contact between an impeller and a casing liner, by automatically controlling change in the impeller gap caused by expansion and contraction of a pump shaft to keep the impeller gap always at a proper value. CONSTITUTION:For instance, when a pump shaft 1a is contracted due to the temperature difference of bearing lubricating water and work liquid and the gap (impller gap) D between an impeller 2 and a casing liner is increased, a hydraulic means 8 is set into operation in response to the output signal of a detector 7 and supplies pressure oil to the upper cylinder above a piston 9b of a piston lifting means 9 and also to a hollow space 13 in a holding 10d of a piston clamping means 10. This causes expansion of the holder 10d and unlocks a piston rod 9c. At the same time, the piston 9b is moved downward, so that the pump shaft 1a is also moved downward via the piston rod 9c and a motor 6, thus reducing the impeller gap D to keep it at a proper value. Thus, it is enabled to operate a pump in a safe and efficient manner by keeping the impeller gap D always at a proper value.
