Abstract

The invention relates to the technical field of pump equipment, in particular to an intelligent permanent magnet zero-leakage pump. The intelligent permanent magnet zero-leakage pump comprises a zero-leakage pump body, wherein the bottom of the zero-leakage pump body is equipped with a base; a permanent magnet synchronous motor stator and an intelligent variable-frequency controller are mounted inthe zero-leakage pump body; the zero-leakage pump body comprises a flow radiator, an isolating sleeve, a synchronous rotor, a bearing, a rotary shaft, an impeller and a pump shell; the permanent magnet synchronous motor stator comprises a heat dissipation housing and a stator which is embedded with three groups of coils; the intelligent variable-frequency controller comprises a control box; and aheat dissipation fan and a plurality of heat dissipation fins are mounted on the control box. The intelligent permanent magnet zero-leakage pump is simple in integral structure, cancels a magnetic shaft coupler needed for a conventional magnetic pump, adopts an intelligent control module of the intelligent variable-frequency controller to safely monitor a working state of the motor and the pump,upgrades original switch type control to be intelligent protection type control, reduces a connecting link, adopts a permanent magnet synchronous motor to improve work efficiency, improves integral system efficiency, and saves energy consumption of a power grid.

Description

technical field [0001] The invention relates to the technical field of pump equipment, in particular to an intelligent permanent magnet non-leakage pump. Background technique [0002] At present, in the transportation of corrosive media in chemical production, petroleum, electric power, electroplating, dyes, pesticides, papermaking, food, textiles and many other industries, long-term transportation of sulfuric acid, hydrochloric acid and hydrofluoric acid of any concentration under the temperature condition of -20℃~150℃ Non-leakage pumps are required for acid, nitric acid, aqua regia, strong alkali, strong oxidizing agent, organic solvent, reducing agent and other strong corrosive media. When selecting the pump type, the requirements for the pump must meet the requirements for the characteristics of the medium, and reliable shaft seals are required for pumps that transport flammable, explosive, volatile low-temperature media (liquefied petroleum gas, etc.), toxic or expensiv...
