Description

Technical Field

[0001] This invention relates to the field of electromagnetic pump technology, and in particular to an electromagnetic pump that is easy to repair quickly. Background Technology

[0002] An electromagnetic pump is a pump that allows a current-carrying fluid to flow in a specific direction under the influence of electromagnetic force when placed in a magnetic field. It utilizes the interaction between a magnetic field and the current in a conductive fluid to create a pressure gradient in the fluid through electromagnetic force, thereby propelling the fluid.

[0003] Existing technologies, such as the small electromagnetic pump with publication number CN206694206U, have a check valve that fails to function properly when it becomes dirty. Traditional maintenance methods require complete disassembly, which interrupts work and affects the continuity of production. Furthermore, if the pressure relief pipe becomes blocked, it is also difficult to unclog and clean. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electromagnetic pump that is easy to repair quickly, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electromagnetic pump that is easy to maintain quickly includes a pump body, an inlet pipe on one side of the pump body, a bracket fixedly connected to the other side of the pump body, an outlet pipe threadedly connected to the bracket, an outlet hole on the side of the pump body near the outlet pipe, a rotating seat rotatably connected to one side of the pump body, and at least two check pipes provided on the rotating seat, the at least two check pipes being alternately coaxial with the outlet pipe through the rotation of the rotating seat.

[0007] Preferably, the check pipe includes a pipe body, which is fixedly connected to the rotating seat. One end of the pipe body is provided with an inlet hole that is coaxial with the outlet hole. The other end of the pipe body is threadedly connected to an end cap, which is provided with a discharge hole that is connected to the outlet pipe. A support spring is provided on one side of the end cap, and a check valve is provided between the support spring and the inlet hole.

[0008] Preferably, an annular arc groove is provided inside one end of the pump body, the check valve end is spherical and adapted to the arc groove, and the liquid outlet is located inside the arc groove.

[0009] Preferably, a pressure relief cap is detachably connected to the outside of the end cap, the pressure relief cap is provided with a pressure relief hole, a countersunk hole is provided at one end of the check valve, and a pressure relief spring is provided between the countersunk hole and the pressure relief cap.

[0010] Preferably, a sealing ring is provided at one end of the liquid outlet pipe.

[0011] Preferably, the center of the rotating seat is provided with an internal hexagonal hole.

[0012] Preferably, the bottom of the internal hexagonal hole is provided with a clearance hole, and a locking screw is provided in the clearance hole, the locking screw being threadedly connected to the pump body.

[0013] The advantages of this invention are: the electromagnetic pump provided by this invention facilitates quick maintenance by rotating the rotating seat to exchange the unused check pipe with the check pipe in use, thereby achieving the function of quick maintenance, facilitating quick cleaning or replacement, and avoiding impact on production.

[0014] The arc-shaped groove of this invention serves as a flow guide. When the pressure is stable, it will not push open the check valve inside the pipe equipped with the pressure relief cap. When the input liquid pressure increases, the pressure relief cap will release pressure, reducing the number of structural components and facilitating maintenance. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, the present invention provides an electromagnetic pump that is easy to repair quickly, including a pump body 1, an inlet pipe 2 on one side of the pump body 1, a bracket 3 fixedly connected to the other side of the pump body 1, an outlet pipe 4 threadedly connected to the bracket 3, an outlet hole 5 on the side of the pump body 1 near the outlet pipe 4, a rotating seat 6 rotatably connected to one side of the pump body 1, the rotating seat 6 having at least two check pipes, the at least two check pipes being alternately coaxial with the outlet pipe 4 by rotating the rotating seat 6, an internal hexagonal hole 61 at the center of the rotating seat 6, a clearance hole at the bottom of the internal hexagonal hole 61, a locking screw 62 in the clearance hole, the locking screw 62 being threadedly connected to the pump body 1, the locking screw 62 securing the rotating seat 6 to one side of the pump body 1, when it is necessary to replace the check pipe, first remove the locking screw 62, insert an internal hexagonal wrench into the internal hexagonal hole 61, and rotate the rotating seat 6 to replace the different check pipes.

[0022] The check valve includes a tube body 7, which is fixedly connected to a rotating seat 6. One end of the tube body 7 is provided with an inlet hole 71, which is coaxial with the outlet hole 5. The other end of the tube body 7 is threadedly connected to an end cap 72, which is provided with a discharge hole 73, which is connected to the outlet pipe 4. A support spring 74 is provided on one side of the end cap 72, and a check valve 75 is provided between the support spring 74 and the inlet hole 71.

[0023] A sealing ring 41 is provided at one end of the liquid outlet pipe 4. The liquid outlet pipe 4 rotates relative to the bracket 3 so that the end face of the liquid outlet pipe 4 presses against the end face of the pipe body 7 to form a seal.

[0024] In this invention, one of the check tubes functions normally. When the internal check tube 75 needs to be replaced, the unused check tube can be swapped with it by rotating the rotating seat 6, thereby achieving a quick repair function and avoiding production disruption.

[0025] During replacement, the outlet pipe 4 rotates away from the pipe body 7 in use through the thread action. The rotating seat 6 rotates and repositions the unused pipe body 7 to be coaxial with the outlet pipe 4. The outlet pipe 4 rotates back to press against the pipe body 7 to form a seal, which can achieve the function of quick replacement. After the pipe body 7 that needs to be repaired is moved out of the working position, the end cap 72 can be removed through the thread, and the support spring 74 and the anti-return 75 can be taken out for easy and quick cleaning or replacement.

[0026] Example 2

[0027] like Figures 1 to 4 As shown, an annular arc groove 11 is provided inside one end of the pump body 1. The check valve 75 is spherical at one end and fits into the arc groove 11. The outlet hole 5 is located inside the arc groove 11. The check valve 75 can slide inside the arc groove 11. The outlet hole 5 is chamfered to facilitate the sliding of the check valve 75 from the outlet hole 5 into the arc groove 11. When the check valve 75 is aligned with the outlet hole 5, the force of the supporting spring 74 to press and block the outlet hole 5 causes a jerking sensation during the rotation of the rotating seat 6, indicating that the corresponding check valve and the outlet hole 5 are coaxial.

[0028] A pressure relief cap 8 is detachably connected to the outside of the end cap 72. The pressure relief cap 8 is provided with a pressure relief hole 81. A countersunk hole 82 is provided at one end of the check valve 75. A pressure relief spring 83 is provided between the countersunk hole 82 and the pressure relief cap 8. The pressure relief spring 83 applies an additional clamping force to the check valve 75. When the input liquid pressure is too high, it can push open the check valve 75 to play a role in pressure relief protection.

[0029] In Embodiment 2, the tube body 7 of the check pipe, which is far from the outlet pipe 4, serves two purposes: firstly, it facilitates quick replacement or cleaning as described in Embodiment 1; secondly, when the input liquid pressure is stable, the pressure of the input liquid can only push open the check valve 75, which is coaxial with the outlet pipe 4. After the check valve 75 is pushed open, the annular arc groove 11 acts as a flow guide. When the pressure is stable, it will not push open the check valve 75 inside the tube body 7 equipped with the pressure relief cap 8. When the input liquid pressure increases, the pressure relief cap 8 plays a role in relieving pressure. Compared with the prior art, this adds an additional pressure relief pipe, reduces structural components, and is equally convenient for maintenance.
