Description

Technical Field

[0001] This invention relates to the field of magnetic pump technology, and specifically to a magnetic pump that integrates sealing and monitoring. Background Technology

[0002] A magnetic pump (also known as a magnetically driven pump) mainly consists of several parts, including a pump head, a magnetic drive (magnetic cylinder), a motor, and a base. The magnetic drive of the pump comprises an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation cover. When the motor drives the outer magnetic rotor to rotate via a coupling, the magnetic field penetrates the air gap and the non-magnetic isolation cover, driving the inner magnetic rotor, which is connected to the impeller, to rotate synchronously. This achieves contactless synchronous power transmission, transforming a potentially leaky dynamic seal structure into a zero-leakage static seal structure.

[0003] For example, according to Chinese patent CN215213977U, a magnetic pump integrating sealing and monitoring consists of an outer magnetic cylinder, an inner magnetic cylinder, and a non-magnetic isolation cover. When the motor drives the outer magnetic cylinder to rotate through a coupling, the magnetic field can penetrate the air gap and the non-magnetic material isolation cover, driving the inner magnetic cylinder connected to the impeller to rotate synchronously, realizing contactless synchronous power transmission. This transforms the easily leaking dynamic sealing structure into a zero-leakage static sealing structure. The pump shaft and inner magnetic cylinder are completely sealed by the pump body and isolation cover, thus completely solving the problems of "running, leaking, dripping, and seeping," achieving high-efficiency sealing performance of the pump body. A monitoring mechanism is installed on the pump body, consisting of a temperature probe, a liquid leakage probe, an anti-dry-run power protector, and a visual bubble detector. This mechanism can monitor the working status of the pump body in real time, promptly detect pump body malfunctions, and handle them in a timely manner, reducing the pump body failure rate.

[0004] The above solution, by installing a monitoring mechanism on the pump body, which consists of a temperature probe, a liquid leakage probe, an anti-dry-run power protector, and a visual bubble detector, can monitor the working status of the pump body in real time and detect pump malfunctions in a timely manner. However, there are still shortcomings: since the monitoring mechanism needs to monitor the inside of the isolation cover, the monitoring mechanism needs to be installed on the isolation cover. However, the monitoring mechanism needs to be connected to the outside, which means that the external magnetic cylinder needs to avoid the connection line of the monitoring mechanism. As a result, the length of the external magnetic cylinder is shortened to two-thirds of the original length, resulting in a decrease in transmission efficiency. Although this can be solved by increasing the length of the pump body, it also increases the overall volume of the magnetic pump. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a magnetic pump that integrates sealing and monitoring. It solves the problem that the monitoring mechanism needs to monitor the inside of the isolation cover, which requires the detection mechanism to be installed on the isolation cover. However, the monitoring mechanism needs to be connected to the outside, which means that the outer magnetic cylinder needs to avoid the connection line of the monitoring mechanism. As a result, the length of the outer magnetic cylinder is shortened to two-thirds of the original length, leading to a decrease in transmission efficiency. Although this problem can be solved by increasing the length of the pump body, it also increases the overall size of the magnetic pump.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A magnetic pump integrating sealing and monitoring includes: a base plate, with casters fixedly installed at all four corners of the base plate's bottom surface; a mounting plate on the top surface of the base plate; a motor fixedly installed on the top surface of the mounting plate; a pump body on one side of the motor; a water outlet pipe fixedly installed on one side of the pump body; and a water inlet pipe fixedly installed on the outer circular wall of the pump body; and a monitoring component disposed inside the pump body for monitoring the internal structure of the pump body.

[0008] By adopting the above technical solution and setting up monitoring components, the operating status of the pump body can be effectively monitored.

[0009] Preferably, the monitoring component includes: a first external magnetic cylinder at one end of the motor drive shaft; a first bearing fixedly sleeved on the inner circular wall of the pump body; a second external magnet fixedly sleeved on the inner circular wall of the inner ring of the first bearing; racks fixedly installed on both sides of the first external magnetic cylinder and the second external magnet that are close to each other; a plurality of support rods fixedly installed on the inner circular wall of the pump body; a second bearing fixedly sleeved on the outer circular wall of the support rods; gears fixedly sleeved on the outer circular wall of the outer ring of the second bearing; two meshing gears forming a group; each group of two gears meshing with two racks respectively; and a sealing cover bolted to one side of the pump body; and a sealing cover fixedly installed on one side of the sealing cover. The pump body has a second sealing strip and a flow cover on the other side. A first sealing strip is fixedly installed on one side of the flow cover. An impeller is movably fitted inside the flow cover. A connecting shaft is fixedly installed on one side of the impeller. One end of the connecting shaft passes through the other side of the pump body and is connected to the inside of the pump body. A bearing seal ring is provided at the connection between the connecting shaft and the pump body. An inner magnet is fixedly installed on one end of the connecting shaft. A temperature sensor, a liquid leakage sensor, and a bubble detector are fixedly installed on the outer circular wall of the sealing cover. The wires of the temperature sensor, the liquid leakage sensor, and the bubble detector all pass through the gap between the first outer magnetic cylinder and the second outer magnet and extend to the outside of the pump body.

[0010] By adopting the above technical solution, and by setting a sealing cover and a sealing strip at the connection between the sealing cover and the pump body, the sealing performance of the inside of the sealing cover is ensured. The temperature sensor, liquid leakage sensor and bubble detector can monitor the inside of the pump body in real time, and monitor leakage temperature and other conditions. By dividing the outer magnetic cylinder into two and connecting them with gears, a gap is left between the first outer magnetic cylinder and the second outer magnet for wiring. This ensures that the area of ​​the inner and outer magnetic cylinders is not reduced while ensuring normal monitoring by the temperature sensor, liquid leakage sensor and bubble detector. Thus, the power transmission efficiency is guaranteed without increasing the overall area of ​​the magnetic pump.

[0011] Preferably, the flow cover is fixedly installed to one side of the pump body by bolt connection, and the pump body is fixedly installed to one side of the motor by bolt connection.

[0012] By adopting the above technical solution, and by setting a flow cover, the flow cover, pump body and motor are connected and installed by bolts, which makes it convenient for staff to disassemble and maintain the magnetic pump.

[0013] Preferably, a coupling is fixedly installed at one end of the motor drive shaft, and a linkage rod is fixedly installed on one side of the first external magnetic cylinder, with one end of the coupling fixedly installed to one end of the linkage rod.

[0014] By adopting the above technical solution and setting up a coupling, the reliability of the magnetic pump is increased by providing overload protection.

[0015] Preferably, a push rod is fixedly installed on one side of the base plate.

[0016] By adopting the above technical solution, and by setting up a push rod, which, together with the universal wheels, makes it easy for workers to move the magnetic pump to the working point.

[0017] Preferably, a hanging ring is fixedly installed on the outer cylindrical wall of the motor.

[0018] By adopting the above technical solution and setting up hanging rings, the magnetic pump can be easily lifted when high-altitude operations are required.

[0019] Preferably, a first flange is fixedly installed at one end of the water outlet pipe, and a second flange is fixedly installed at one end of the water inlet pipe.

[0020] By adopting the above technical solution, and by setting a first flange and a second flange, the magnetic pump can be easily connected to the water pipe.

[0021] Preferably, the mounting plate is fixedly installed to the top surface of the base plate by bolt connection.

[0022] By adopting the above technical solution, by setting up an installation plate, and by fixing the installation plate to the top surface of the base plate with bolts, the magnetic pump can be separated from the base plate when it needs to be lifted.

[0023] In summary, the present invention has the following main beneficial effects:

[0024] By setting a sealing cover and a sealing strip at the connection between the sealing cover and the pump body, the sealing of the inside of the sealing cover is ensured. Temperature sensors, liquid leakage sensors, and bubble detectors can monitor the inside of the pump body in real time, monitoring leakage temperature and other conditions. By dividing the outer magnetic cylinder into two and connecting them with gears, a gap is left between the first outer magnetic cylinder and the second outer magnet for wiring. This ensures that the temperature sensor, liquid leakage sensor, and bubble detector can monitor normally without reducing the area of ​​the inner and outer magnetic cylinders, thus ensuring power transmission efficiency without increasing the overall area of ​​the magnetic pump.

[0025] By installing a flow cover, and connecting the flow cover, pump body, and motor with bolts, the magnetic pump can be easily disassembled and maintained by staff. The installation of a coupling provides overload protection and increases the reliability of the magnetic pump.

[0026] By setting up push rods, which, together with casters, make it easy for workers to move the magnetic pump to the work point. By setting up hanging rings, the magnetic pump can be easily lifted when it is necessary to work at height.

[0027] By setting a first flange and a second flange, the magnetic pump can be easily connected to the water pipe. By setting an mounting plate, the mounting plate can be fixed to the top surface of the base plate by bolt connection, and the magnetic pump can be separated from the base plate when it needs to be lifted.
