Description

Technical Field

[0001] The utility model relates to the technical field of magnetic drive pumps, in particular to a power transmission mechanism of a magnetic drive pump. Background Art

[0002] Magnetic drive pump, also known as plastic acid and alkali resistant magnetic pump, is a pump equipment that uses the working principle of magnetic coupling to achieve contactless power transmission. It is mainly composed of pump body, impeller, magnetic coupling (magnetic coupling), isolation sleeve and electric motor. Magnetic drive pump has the characteristics of full sealing, no leakage, corrosion resistance, high efficiency and energy saving. It is particularly suitable for conveying flammable, explosive, volatile, toxic, rare and precious liquids and various corrosive liquids. It is an indispensable conveying equipment in the fields of petroleum, chemical, pharmaceutical, smelting and other industries.

[0003] During use, the existing magnetic drive pump requires a motor as a power source. During operation, the motor converts electrical energy into mechanical energy through the principle of electromagnetic induction. In this process, resistance loss will be generated due to the flow of current in the conductor, and the change of the magnetic field will also generate iron loss in the iron core. These losses will eventually be converted into heat energy, causing the motor temperature to rise. For this reason, the motor needs to use a heat sink for heat dissipation. However, a large amount of dust will accumulate on the heat sink during the use or non-use of the existing motor, and the accumulation of a large amount of dust will affect the heat dissipation efficiency of the heat sink. In order to avoid the adverse effects of dust on the heat dissipation effect of the heat sink and further improve the efficiency of the heat sink in dissipating heat from the dual-axis motor, based on this, a power transmission mechanism of a magnetic drive pump is now provided, which can eliminate the disadvantages of the existing device.

[0047] The above embodiment discloses a power transmission mechanism for a magnetically driven pump, wherein it is particularly noted that: the connecting rod 2016 is made of a thermally conductive material, the inner cavity of the connecting rod 2016 is filled with carbon dioxide gas, and the end of the telescopic airbag 2015 away from the limiting slide 2014 is fixedly connected to the rotating disk 2012. Therefore, during the rotation of the rotating disk 2012, the sliding insert 2013 does not slide due to the centrifugal force.

[0048] When in use, the dual-axis motor 4 is started to drive the pump body 1 through the magnetic transmission 3 to perform a leak-free liquid delivery operation. At this time, the rotating disk 2012 rotates under the drive of the other output end of the dual-axis motor 4;

At the same time, a sliding sleeve 2011 is driven by the crescent pin and the thread of the reciprocating screw 2010 to move back and forth along the outer wall of the reciprocating screw 2010. At this time, the moving frame 201 is driven by one sliding sleeve 2011 to drive the other sliding sleeve 2011 to slide along the outer wall of the limit rod 203. At the same time, during the movement of the moving frame 201, the outer wall of the heat sink on the dual-axis motor 4 is cleaned by the cleaning brush, so as to clean the dust accumulated on the heat sink, thereby preventing the accumulated dust from adversely affecting the heat dissipation effect of the heat sink.
