Problems solved by technology

However, increasing the amount of dye liquor in the dyeing machine vat will increase the liquor ratio of the dyeing machine, making the dyeing machine consume more dyes and water, and ultimately increase the economic cost and increase the source of environmental pollution.

Abstract

The invention discloses a dyeing machine power system with a self-pressurization function. The system mainly comprises a motor, a reducer pipe, a dye liquor inlet pipe, a dye liquor outlet pipe, a liquor storage cavity, a volute, a secondary impeller, a cooling pipe, a sealing assembly, a spoiler, a coupling, a blind flange, a nozzle and the like. Kinetic energy of dye liquor is converted into pressure energy before the dye liquor enters a pump assembly through the reducer pipe, and the pressure of the dye liquor at a pump inlet is directly improved, so that the net positive suction head of a pump is greatly improved, and the liquor ratio of a dyeing machine will not be increased. A self-circulation pipeline is adopted for cooling a mechanical sealing part of the impeller pump, so that the pump assembly is more compact, and the reliability of the pump is improved. The problem of contradiction between the net positive suction head of the pump assembly of the dyeing machine and the liquor ratio of the drying machine is solved by means of the dynamic pressure conversion principle skillfully, the technology efficiency of the dyeing machine can be effectively improved, and the economic cost is reduced.

Description

technical field [0001] The invention relates to the technical field of dyeing machinery, in particular to a dyeing machine power system with a self-pressurizing function. Background technique [0002] The power system is the core component of the dyeing machine, and its performance is directly related to the energy consumption and process efficiency of the dyeing machine. The dye liquor circulation power system of the dyeing machine is usually powered by a centrifugal pump, but the centrifugal pump has cavitation problems. Traditionally, in order to solve the cavitation problem of the centrifugal pump, it is usually necessary to increase the dye liquor storage capacity in the dyeing machine cylinder to increase the pressure at the inlet and outlet of the centrifugal pump. However, increasing the amount of dye liquor in the dyeing machine vat increases the liquor ratio of the dyeing machine, making the dyeing machine consume more dyestuffs and water, which ultimately increas...
