Abstract
A magnetic drive pump with a bearing block comprises a pump body, a pump cover, a pump shaft, an impeller, an outer magnet rotor, an inner magnet rotor, a spacer sleeve, a connecting rack and a motor. The spacer sleeve is disposed between the outer magnet rotor and the inner magnet rotor. A pump cavity forms between the pump cover and the pump body, and an inner cavity forms between the pump cover, and the inner magnet rotor and the spacer sleeve. The magnetic drive pump further comprises the bearing block mounted on the pump cover. The center of the pump cover is provided with a spigot used for mounting the bearing block. The pump cover is provided with two straight through holes penetrating the pump cavity from front to rear and a slant through hole. The bearing block is provided with a slant hole communicated with the slant through hole. The two straight through holes allow air or medium in the inner cavity of the spacer sleeve to be smoothly discharged, the slant through hole and the slant hole in the bearing block allow the medium producing pressure in the pump cavity to pass, and accordingly, a sliding bearing pair of the magnetic pump is mandatorily lubricated. The reasonable structural design ensures that all internal circulation lubricating systems can provide sufficient pressure and flow to allow the pump to stably operate.
