Abstract

The utility model provides a magnetic transmission pump comprising a motor end and a hydrofoil end containing the casing and hydrofoil. The motor and the hydrofoil are connected by actuator that contains a base of drive magnet connecting of the motor and a base of driven magnet connecting of the hydrofoil. Between the drive magnet set and the driven magnet set is the ceramic isolating layer. The utility model uses the drive and driven magnet set as the actuator of the motor end and the hydrofoil end, to push the hydrofoil to rotate in accordance with the repulsive force between the same magnetic properties, so the two ends will not contact and eliminate abrasion and noise during working. Between the drive and driven magnet is equipped with a ceramic isolating layer, therefore the unexpected current leakage will not transmit to the hydrofoil end and assure the operation safety.

Description

Magnetic drive pump

Technical field

The utility model relates to a kind of pump, particularly can utilize the pump of magnetic drives.

Technical background

In present life and the production, the use of various pumps very extensively, the having nothing in common with each other of the working method of various pumps and purposes, greatly to field irrigation, breed fish for a short time to family's fish jar, all to use pump, pump be modern life and produce in indispensable machine tool.

The kind of the pump on the market is very various, and motor-mount pump, oil hydraulic pump, thermal pump or the like are for example arranged, and wherein, motor-mount pump can be used for carrying various fluids, semifluid, thickness body, and motor-mount pump can be carried the compounding substances that is mingled with block in the above-mentioned states of matter.

Motor-mount pump drives waterleaf then by motor drive drive mechanism and comes work, existing motor-mount pump generally all brings transmission by drive wheel or transmission, so the friction of the drive part that produces in the working procedure and noise are all very big, long-term friction can make the drive part of pump inside produce wearing and tearing, reduced working life, need irregular wearout parts to be checked or changes, and transmission shaft is to connect motor, in case motor is damaged and produces the situation of electric leakage, electricity can be sent in the liquid that pump carries by transmission shaft always, is unfavorable for staff's personal safety.

Summary of the invention

The utility model provides a kind of magnetic drive pump that can effectively overcome above-mentioned deficiency, and low, the wear-resistant and good insulating of its noise has ensured personal safety.

The purpose of this utility model is achieved in that it includes motor-end and waterleaf end, motor-end includes shell and inner motor thereof, the waterleaf end includes shell and inner waterleaf thereof, connect with driving mechanism between motor and the waterleaf, its improvement is: driving mechanism includes initiatively magnetite bearing and driven magnetite bearing, initiatively the magnetite bearing is connected with motor, driven magnetite bearing connects waterleaf, magnetite in the driving and driven magnetite bearing is that circumferential distributes, and the magnetite in the driving and driven magnetite bearing is that opposite pole is spaced;

In the said structure, between active magnetite group and driven magnetite group, be provided with the magnetic conduction dielectric isolation layer;

In the said structure, the magnetic conduction dielectric isolation layer is ceramic separation layer;

In the said structure, be evenly distributed with 6 magnetites on the driving and driven magnetite bearing.

In sum, the utility model uses the driving mechanism of two groups of magnetites of principal and subordinate as motor-end and waterleaf end, the principle of utilizing two groups of like poles in the magnetite to repel mutually promotes the rotation of waterleaf, so two ends do not come in contact, wearing and tearing and noise when having eliminated work, and between master and slave two groups of magnetites, be provided with a ceramic separation layer,, guaranteed the safety in the working procedure so the electric leakage of the accident of motor-end can not be transmitted to the waterleaf end.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the generalized section of the utility model magnetic drive pump;

Fig. 2 is the arrangement schematic representation of magnetite on the utility model magnetic drive pump magnetite bearing;

Fig. 3 is the utility model magnetic drive pump principal and subordinate magnetite bearing tradition schematic representation.

Embodiment

As shown in Figure 1, the magnetic drive pump of present embodiment includes motor-end 100 and waterleaf end 200, motor-end 100 includes shell 110 and inner motor 120 thereof, waterleaf end 200 includes shell 210 and inner waterleaf 220 thereof, be provided with initiatively magnetite bearing 130 and driven magnetite bearing 230 between motor 210 and the waterleaf 220, initiatively magnetite bearing 130 is connected with motor 120, driven magnetite bearing 230 connects waterleaf 220, is provided with ceramic insulating layer 300 between active magnetite bearing 130 and driven magnetite bearing 230.

As shown in Figure 2, initiatively in the magnetite bearing 130 and in magnetite 131 distribute for circumferential, initiatively the magnetite 131 in 130 is for opposite pole is spaced in the magnetite bearing, the magnetite distributed architecture on the driven magnetite bearing 230 is identical with active magnetite bearing 130.

As shown in Figure 3, initiatively in the magnetite bearing 130 with driven magnetite bearing 230 in

magnetite

131 and 231 principle of utilizing two groups of like poles in the magnetite to repel mutually make magnetite 131 promote magnetites 231 to rotate the magnetic force that arrow logo repels each other among the figure.
