Multi-stage pump production line

Abstract

The invention discloses a multi-stage pump production line. The multi-stage pump production line comprises a workbench, a protective shell, a cutting device arranged on the protective shell, a plurality of auxiliary devices arranged on the cutting device and a driving device arranged on the protective shell. The cutting device comprises a material blocking frame arranged on the workbench, a first driving piece used for connecting the workbench and the material blocking frame, a plurality of supporting pipes arranged on the protective shell, a plurality of fixing holes formed in the supporting pipes, a plurality of fixing balls arranged on the material blocking frame, a plurality of pressing blocks arranged on the protective shell, a plurality of first telescopic rods used for connecting the pressing blocks and the protective shell correspondingly, a plurality of cutting rails arranged on the protective shell, a plurality of cutting blocks arranged on the cutting rails correspondingly, a plurality of second telescopic rods arranged on the cutting blocks correspondingly, a plurality of second telescopic rods arranged on the cutting blocks correspondingly, a plurality of cutting frames separately arranged on the second telescopic rods, and a plurality of cutting knives separately arranged on the cutting frames.

Description

technical field [0001] The invention belongs to the field of multistage pump processing equipment, and in particular relates to a multistage pump production line. Background technique [0002] The multi-stage pump is a centrifugal pump that is combined with the water inlet and outlet section and the middle section through a tie rod. Its output water pressure can be very high, and it also depends on the rotation of the impeller to obtain centrifugal force, so as to output the water flow. When the gas density reaches the mechanical vacuum pump The working range is drawn out, so as to gradually obtain high vacuum; while in the prior art, when processing multi-stage pumps, the processing of the inlet and outlet pipes is an important part, and the length of the inlet and outlet pipes in multi-stage pumps of different sizes is also different. Different, but when existing equipment processes inlet and outlet pipes of different lengths, it generally requires manual operation or repl...
