Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic pumps, and in particular relates to a magnetic pump with inlet and outlet pump heads having different directions. Background Art

[0002] The magnetic pump (also called magnetic drive pump) is mainly composed of several parts such as pump head, magnetic transmission (magnetic cylinder), 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 a 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 zero-leakage static sealing structure. Since the pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, the "run, bubbling, dripping, and leakage" problem is completely solved. Although the functionality of the magnetic pump is very strong, the input and output ends of the existing magnetic pump are straight pipes, and the connection of the pipeline cannot change direction according to the route of the pipe layout, thereby reducing the scope of use of the magnetic pump.

[0003] To this end, a magnetic pump with a diametrical inlet and outlet pump head with a bulletin number of "CN218817039U" solves the problem that although the functionality of the magnetic pump in the prior art is very strong, the input and output ends of the existing magnetic pump are straight pipes. For operations in some special positions, the connection of the pipeline is not very convenient, which reduces the practicality of the magnetic pump. A magnetic pump with a diametrical inlet and outlet pump head includes a magnetic pump, an output pipe and an input pipe. The output pipe is connected to the output end of the magnetic pump, and the input pipe is connected to the input end of the magnetic pump. The input pipe and the output pipe are both connected with a docking assembly. The docking assembly includes a docking structure, a connecting pipe sleeve and a docking pipe head, which can realize the change of the position of the end of the docking pipe head, thereby facilitating the connection with the pipeline in a special position, realizing the diametrical movement adjustment of the connection position of the magnetic pump, and improving the practicality of the magnetic pump.

[0004] However, for the above-mentioned magnetic pump with unidirectional inlet and outlet pump heads, although the butt joint can be driven to rotate inside the connecting pipe sleeve by grabbing the butt joint, thereby changing the position of the connecting end of the butt joint, thereby facilitating the connection of the pipeline, there are still the following obvious defects during use: when the butt joint is in the state of rotating the straight pipe, only the connected soft pipes and pipes that are easy to change the direction can be changed, and when the butt joint is connected to the hard pipe fittings, it can only rotate in a straight line because the butt joint is a straight pipe, and the direction of the hard pipe fitting cannot be changed according to the different directions of the pipe laying. Utility Model Content

[0005] The utility model aims to provide a magnetic pump with inlet and outlet pump heads with different directions, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a magnetic pump with a pump head with different inlet and outlet directions, comprising:

The sleeve is threadedly sleeved on the pump pipe and sealed by a sealing ring A, thereby achieving quick connection of the hose and being able to adjust the length of the connection between the hose and the external pipe.

[0011] Preferably, one end of the pump tube is provided with a sealing flange connected to the docking flange, and the other surface of the sealing flange extends outward with an embedded pipe head, and the outer periphery of the embedded pipe head is sleeved with a sealing ring B for connecting and sealing with the docking flange. The sleeve and the docking flange can be embedded and fixed and then sealed by the sealing ring B to avoid leakage at the pipeline connection.

[0012] Preferably, one side of the docking flange is extended outwardly to provide an external convex connecting pipe head, and the surface of the external convex connecting pipe head is provided with an internal concave binding groove which is conducive to binding the external connecting pipe by steel wire, so that the external pipe can be connected by means of the flange, and the pipe with a diameter larger than the external convex connecting pipe head can be directly inserted into the external convex connecting pipe head and tightened and fixed on the external convex connecting pipe head by steel wire.

[0013] Preferably, a base block is provided on one side of the bottom of the pump body and the motor, and a pump body cushion is horizontally fixed to the bottom surface of the base block, which can fix the magnetic pump at a specified position to avoid position deviation caused by vibration during operation.

[0016] Through the pump tube with threaded surface connected to the input pipe port and the output pipe port, and the sleeve threadedly connected to the outside of the pump tube and the sealing flange connected to one end of the sleeve, the sleeve can be rotated according to the distance between the conduit and the object before the external pipeline is connected to the connecting hose, so as to adjust the length between the sleeve and the pump tube, so as to adjust the distance between the pipeline and the object, thereby reducing the large space occupied by the pipeline during laying, and then allowing the pipeline to be laid with a smaller distance between the object, further improving the scope of use and practicality of the magnetic pump.
