Borax solution circulation pump

Abstract

The invention relates to a borax solution circulation pump which comprises an upper trough and a lower trough. The borax solution circulation pump is characterized in that the upper trough is arranged on the left upper side of the lower trough, a motor is installed on the right upper side of the lower trough, a U-shaped pipe is arranged inside the lower trough, a U-shaped pipe end A and a U-shaped pipe end B are respectively arranged at two ends of the U-shaped pipe, the U-shaped pipe end A is communicated with the upper trough, and the U-shaped pipe end B is open; an output shaft of the motor is connected with a long shaft, an impeller is installed at the bottom of the long shaft, and the bottom of the long shaft is arranged on the U-shaped pipe end B; the motor is installed on a coupling-shaft fixing frame, an outer bearing bush cover is installed at the bottom of the coupling-shaft fixing frame, and the notch of the lower trough is completely sealed through the outer bearing bush cover; a water splashing disc is installed under the outer bearing bush cover. By the arrangement, the problem that a borax pump and a pipeline must be taken apart for cleaning before use can be solved.

Description

technical field [0001] The invention relates to a circulation pump, in particular to a special circulation pump for borax solution. Background technique [0002] The bead wire needs to be mechanically dephosphorized, pickled and boronized before drawing, which is beneficial to powder and lubrication during subsequent drawing. When boriding the steel wire, it is necessary to heat the borax solution to above 80 degrees, pump the borax solution in the lower tank to the overflow upper tank and circulate repeatedly, so that the steel wire can pass through the overflow upper tank To realize the boronization of steel wire surface. The borax solution is in a solidified state at room temperature, because the heating and circulation of the borax solution will stop after the car is off duty, so the pump must be disassembled from the solution immediately after the car is stopped, and the solution in the pump body and pipeline must be cleaned before the next drive Then reinstall it int...

AI Technical Summary

Problems solved by technology

Due to the complex structure of the current centrifugal pump, the gap between the impeller and the pump body is closely matched, and the surrounding area of ​​the impeller will be stuck if it is not cleaned up after parking, and it will be stuck when it is restarted next time. The inside of the pipeline must be cleaned, otherwise the pipeline will be blocked in the next use

In addition, once a small amount of solution enters between the dynamic and static rings of the mechanical seal, tiny borax particles will form after the pump is stopped and cooled, and the dynamic and static rings will soon wear out when the pump is started again.
