Abstract

The invention relates to the technical field of self-priming pumps, in particular to a magnet-free idling-resistant integrated modular temperature-resistant and corrosion-resistant high-lift self-priming pump. The magnet-free idling-resistant integrated modular temperature-resistant and corrosion-resistant high-lift self-priming pump comprises a motor and a pump head driven by the motor to pump liquid. The motor comprises a motor shell made of plastic, corrosion-resistant bearing seats, a corrosion-resistant motor shaft, a rotor assembly and a stator. The two ends of the corrosion-resistant motor shaft are connected into the corrosion-resistant bearing seats in a shaft mode through corrosion-resistant bearings. The rotor assembly is formed by coating the surface of a rotor with a rotor plastic shell, and is connected to the outer wall of the corrosion-resistant motor shaft in a sleeving mode. The stator is fixed to the inner wall of the motor shell and is arranged outside the rotor assembly in a gap and sleeving mode, and the gap is 300-600 micrometers. Compared with the prior art, the magnet-free idling-resistant integrated modular temperature-resistant and corrosion-resistant high-lift self-priming pump requires no magnet, the magnetic density gap can reach 300-600 micrometers, and the problem of narrow magnetic density gap of an asynchronous motor is solved; the plastic is used for realizing the isolation of the pump head for circulating liquid from the motor, and the corrosion-resistant effect is achieved; and the structure is simple, transmission is simple, abrasion resistance and corrosion resistance are achieved, self priming is realized, and the shortcomings that a pump with a magnet is complicated, prone to being damaged, prone to leaking, and not resistant toidling are overcome.

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to a non-magnet, idling-resistant integrated modular heat-resistant, corrosion-resistant, high-lift self-priming pump. Background technique [0002] According to the survey on the application of chemical auxiliary pump products in the global market, the most corrosion-resistant and zero-leakage pump in the market is the magnetic pump. The magnetic pump is also called a magnetic drive pump, which is mainly composed of a pump head, a magnetic cylinder of a magnetic drive, a motor, and a base. The magnetic drive of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupling, the magnetic field can penetrate the air gap and the non-magnetic material isolation sleeve, and drive the inner magnetic rotor connected to the impeller to rotate syn...
