Description

Technical Field

[0001] The invention belongs to the technical field of magnetic pumps, and in particular relates to a noise-reducing and easy-to-maintain magnetic pump. Background Art

[0002] The magnetic pump is mainly composed of several parts such as the pump head, magnetic transmission, motor, base, etc. The magnetic transmission 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 isolation sleeve, driving the inner magnetic rotor connected to the impeller to rotate synchronously, realizing contactless synchronous transmission of power, and converting the dynamic sealing structure that is prone to leakage into a static sealing structure with zero leakage.

[0003] The existing magnetic pump has the following disadvantages: the pump head and the middle seat are fixedly connected by multiple bolts, so tools are needed to tighten the multiple bolts, which is not convenient for quick disassembly and assembly of the magnetic pump head, thereby affecting the maintenance efficiency of the magnetic pump. Summary of the invention

[0004] The present invention provides a noise-reducing and easily-maintained magnetic pump, which aims to solve the problem in the prior art that a pump head and a middle seat are fixedly connected by multiple bolts, thereby requiring the use of tools to tighten the multiple bolts, making it inconvenient to quickly disassemble and assemble the pump head of the magnetic pump, thereby affecting the maintenance efficiency of the magnetic pump.

[0005] The present invention is achieved in this way: a noise-reducing and easy-to-maintain magnetic pump comprises a middle seat, the outer wall of the middle seat is bolted to the motor, and the outer wall of the middle seat is provided with a pump head, the outer wall of the pump head is fixedly connected to a mounting plate, and the outer wall of the mounting plate is fixedly connected to a mounting ring, the outer wall of the mounting ring is fixedly connected to a limiting arc piece, and three limiting arc pieces are provided, the outer wall of the middle seat is provided with a mounting groove matching the mounting ring and the limiting arc piece, and the inner wall of the mounting groove is slidably connected to a limiting push rod, the outer wall of the limiting arc piece is provided with a limiting hole matching the limiting push rod, and the outer wall of the limiting push rod is fixedly connected with a spring, the spring is located between the middle seat and the limiting push rod, and the outer wall of the limiting push rod is fixedly connected with a connecting rod, the connecting rod and the middle seat are slidably connected, and the upper surface of the connecting rod is fixedly connected with an operating piece, the lower end outer wall of the operating piece is threadedly connected to a limiting sleeve, and the limiting sleeve and the middle seat are rotatably connected.

[0006] Preferably, the outer wall of the limiting sleeve is provided with anti-slip grooves.

[0007] Preferably, the outer wall of the limiting push rod is provided with a hemispherical guide head.

[0008] Preferably, a protective shell is provided on the outer wall of the motor, and heat dissipation holes are opened on the outer wall of the protective shell, and the heat dissipation holes are evenly distributed on the outer walls on both sides of the protective shell.

[0009] Preferably, a fan blade is fixedly connected to the output end of the motor.

[0010] Preferably, the protective shell includes a mounting plate, and the mounting plate is fixedly connected to the motor, the outer wall of the mounting plate is provided with an external thread, and the inner wall of the protective shell is provided with an internal thread matching the external thread.

[0011] Preferably, the protective shell is made of stainless steel.

[0012] Preferably, an aluminum foam metal layer is fixedly connected to the inner wall of the protective shell.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] The pump head is installed on the middle seat by inserting the mounting ring into the mounting groove and rotating the pump head to make the mounting ring rotate in the mounting groove, so that the limit arc piece is clamped into the clamping groove in the mounting groove, and the limit arc piece is confined in the mounting groove, so that the pump head and the middle seat are quickly connected. The rotation of the limit arc piece in the mounting groove will cause the limit push rod to retract. When the limit arc piece is installed in place, the limit push rod is aligned with the limit hole, and the limit push rod can enter the limit hole of the limit arc piece through the elastic force of the spring to restore, thereby preventing the limit arc piece from being moved due to the vibration of the motor when it is working. Displacement occurs in the installation groove, which improves the stability of the installation. By pressing the operating piece and rotating the limit sleeve, the operating piece can be lowered in the limit sleeve, ensuring that the limit push rod is deeply inserted into the limit hole, preventing the limit push rod from being displaced by the vibration of the motor when it is working, and further improving the stability of the installation of the pump head and the middle seat. The personnel rotates the limit sleeve and pulls the operating piece upwards to disengage the limit push rod from the limit arc piece. The personnel rotates the pump head to disengage the mounting plate from the middle seat, which facilitates the rapid disassembly and assembly between the pump head and the middle seat and improves the maintenance efficiency of the magnetic pump.
