Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pumps, in particular to a no-load running stainless steel magnetic pump. Background Art

[0002] The stainless steel magnetic pump is an improved version of the traditional mechanical seal pump. It uses the principle of magnetic drive to realize the rotation of the pump shaft, thereby driving the flow of liquid. Compared with traditional pumps, the magnetic pump does not rely on mechanical seal components, but transmits power through the interaction of internal and external magnetic fields, thereby effectively avoiding the problems of seal failure, leakage and maintenance difficulties existing in conventional mechanical seal pumps.

[0003] However, when the stainless steel magnetic pump is running at no load, because there is no liquid flowing in the pump to absorb the heat of the pump body, it will cause the motor to be overloaded, generate severe heat and damage the motor. At the same time, since the pump body has no fluid medium to support it when it is no load, large vibrations may occur. These vibrations will not only cause potential damage to the equipment, but also affect the comfort of the operating environment.

[0004] Therefore, it is urgent to provide a stainless steel magnetic pump that runs at no load to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a stainless steel magnetic pump that runs at no load.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: providing a stainless steel magnetic pump running at no load, comprising a shock-absorbing platform, a motor is mounted on the shock-absorbing platform, and a heat dissipation mechanism is fixedly mounted on one side of the motor;

[0007] A coupling mechanism is fixedly mounted on one side of the motor, and a magnetic pump body is rotatably mounted on one side of the motor;

[0008] A pump cover is fixedly mounted on one side of the connecting mechanism;

[0009] The motor is fixedly connected to the pump cover with a plurality of fixing mechanisms.

[0010] The utility model is further configured as follows: the shock-absorbing platform includes a fixed base, a plurality of telescopic fixed columns are installed on the fixed base, a plurality of rubber pads are installed on the fixed base, corresponding steel plates are installed between the plurality of rubber pads, upper connecting plates are installed on the top of the plurality of rubber pads, and corresponding rubber protective layers are installed between the upper connecting plates and the fixed base.

[0011] Through the above technical solution, the telescopic fixed column can adjust the height and stability of the platform. When the platform is vibrated, the telescopic function can absorb part of the vibration energy and play a buffering role. At the same time, the rubber pad can effectively absorb vibration and impact force while providing a certain degree of elasticity, thereby reducing the impact of external vibration on the platform. A steel plate is provided under each rubber pad, which further reduces the impact of vibration on the platform by dispersing vibration.

[0012] The utility model is further configured as follows: the heat dissipation mechanism includes a heat dissipation plate fixedly mounted on one side of the motor, a protective shell fixedly mounted on the heat dissipation plate, and a heat dissipation fan fixedly mounted on one side of the interior of the protective shell.

[0013] Through the above technical solution, the heat sink is fixedly installed on one side of the motor as the main heat conduction and dissipation medium. The cooling fan is installed on one side inside the protective shell, directly accelerating the heat dissipation process through air flow. The operation of the cooling fan takes away the hot air from the surface of the heat sink and discharges it outside the heat dissipation mechanism, thereby improving the efficiency of the entire heat dissipation system.

[0014] The utility model is further configured as follows: the connecting mechanism includes a connecting frame fixedly mounted on one side of the motor, and the connecting frame is fixedly connected to the motor via a fixing nut.

[0015] Through the above technical solution, the function of the connecting mechanism is to firmly connect the connecting frame and the motor through the fixing nut, ensuring that the motor can stably cooperate with other components during operation and prevent the motor from loosening or failing.

[0016] The utility model is further configured as follows: the magnetic pump body includes an outer magnetic steel assembly rotatably mounted on the output shaft of the motor, an isolation sleeve is sleeved inside the outer magnetic steel assembly, an inner magnetic steel assembly is sleeved inside the isolation sleeve, a pump shaft is sleeved inside the inner magnetic steel assembly, expansion sleeves are sleeved on both sides of the pump shaft, shaft sleeves are sleeved on both expansion sleeves, a partition is sleeved on the pump shaft, sealing rings are sleeved on both sides of the partition, an impeller is fixedly mounted on the pump shaft, and the impeller and the pump shaft are fixedly mounted by a locking nut.

[0017] Through the above technical solution, the outer magnetic steel assembly starts to rotate, and the generated magnetic force is transmitted to the inner magnetic steel assembly, driving the pump shaft and impeller to rotate. At the same time, the pump shaft is connected with the expansion sleeve and the shaft sleeve to ensure the stable rotation of the pump shaft and effectively transmit power to complete the liquid transportation work. The sealing ring and partition play a sealing and protective role, ensuring that the pump operates under efficient and stable conditions.

[0018] The utility model is further configured as follows: the pump shaft is fixedly mounted on the inner magnetic steel assembly through a screw nut, and grooves for mounting a sealing ring are provided on both sides of the partition.

[0019] Through the above technical solution, during the operation of the pump, the nut fixes the pump shaft and the internal magnetic steel assembly to ensure smooth magnetic transmission. The design of the partition and the sealing ring can effectively isolate the magnetic transmission part from the liquid delivery part, maintain the sealing of the pump and prevent leakage, thereby improving the operating efficiency and service life of the pump.

[0020] The utility model is further configured as follows: multiple groups of the fixing mechanisms include multiple fixing brackets fixedly mounted on the motor and the pump cover, and the multiple fixing brackets and the upper connecting plate are fixedly mounted by hexagonal nuts.

[0021] Through the above technical solution, the use of hexagonal nuts makes the installation process more secure and also facilitates disassembly and maintenance when necessary.

[0022] The beneficial effects of the utility model are as follows:

[0023] 1. The utility model effectively reduces the vibration generated by the stainless steel magnetic pump during operation by designing a shock-absorbing platform. The shock-absorbing platform can absorb and disperse the vibration energy from the equipment, thereby reducing the impact on the stainless steel magnetic pump and the surrounding environment, and improving the stability and durability of the stainless steel magnetic pump.

[0024] 2. The utility model can effectively improve the heat dissipation efficiency of the motor by designing a heat dissipation mechanism, ensuring that the stainless steel magnetic pump maintains a stable operating temperature when running at no load or for a long time, so as to prevent the motor temperature from being too high and causing damage to the motor.
