PURPOSE:To improve adiabatic effect of a heat insulating plate by sending drain of sahft sealing water at the drive side and driven side of a pump body into an adiabatic piping provided on said plate. CONSTITUTION:A heat insulating plate 5 coated with asbestos is mounted by welding on a pin seat embedded in a pin block 3 of concrete between a pump body 1 and a pump installing floor surface and a pump leg installing portion provided on the upper portion of a base 2. A plurality of pipings 6 are provided on the plate 5 not to contact the pump body 1. By connecting these adiabatic pipings 6 to drain of shaft sealing water at the drive and opposite sides of the pump body is prevented the axis of the pump shaft from disorder caused by thermal expansion of the base. |
