Abstract
The invention provides a hard alloy amphibious mine vertical pump capable of being idled and connected in series. The mine vertical pump is characterized in that third bearing chambers and single-end-face second mechanical seal chambers are arranged at the lower end of a pump shaft; oil seal chambers are arranged above the single-end-face second mechanical seal chambers; and clamp nuts of an impeller are provided with rotary sheaths extending out of the circumferences of the oil seal chambers. The mine vertical pump has the following advantages that after the third bearing is protected by the second mechanical seal and the clearances of shaft sleeves or impeller chomas of a single-stage pump and a multistage pump of the mine vertical pump are enlarged through wear, the third bearing is reliably protected, so that the pump shaft can hardly violently vibrate and the interlocking loss and fault rate of vibration will substantially fall.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running can to connect amphibious vertical pump for mine, it is land and amphibious type water pump dual-purpose under water, is applicable to carry in liquid containing the vertical pump of the sand-discharging submerged pump of solid abrasive particles or land.
Background technique
Prior art, the patent of invention of " vertical pump for mine " by name has three: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0.Original vertical pump for mine is the motor single-stage pump coaxial with pump and multistage pump, is all cantilevered axle in disclosed file, only in motor, has two bearings.Therefore, after sand discharge, after the gap of its single-stage pump and the axle sleeve of multistage pump or impeller port ring is worn and increases, easy generation high vibration, sometimes vibration makes the nut of fastening impeller release to come off, make alloy seal ring shatter sometimes, and linksystem damage occurs, these markets directly having affected this pump are expected.At present, the vibration that the relevant cantilevered axle not yet retrieving this vertical pump for mine is long, sand discharge is worn and torn to be caused and eliminate the concrete way of vibration.
Summary of the invention
