Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump technology, specifically a diaphragm pump with multi-point displacement function. Background Technology

[0002] Diaphragm pumps, also known as control pumps, are a major type of actuator. They receive control signals from the control unit and use power to change the flow rate of fluids. The role of diaphragm pumps in the control process is to receive control signals from the regulator or computer, change the flow rate of the controlled medium, and maintain the controlled parameters within the required range, thereby achieving automation of the production process. If we compare automatic control systems with manual control processes, the detection unit is like the human eye, the control unit is like the human brain, and the actuator—the diaphragm pump—is like the human hand and foot. To achieve the regulation and control of a certain parameter in the process, such as temperature, pressure, flow rate, liquid level, etc., diaphragm pumps are indispensable.

[0003] Most existing diaphragm pumps do not have multi-point displacement capabilities during use; they can only move liquid from one place to another. When multiple displacements are needed, additional diaphragm pumps are required, resulting in complex pipeline layouts and increased equipment investment and maintenance costs.

[0004] Based on this, a diaphragm pump with multi-point displacement function is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a diaphragm pump with multi-point displacement function, so as to solve the problem that most of the prior art does not have multi-point displacement function and can only move liquid from one place to another.

[0007] A diaphragm pump with multi-point displacement function includes a base, a support frame is provided on the top of the base, a diaphragm pump body is provided on the top of the support frame, an inlet pipe is connected to the input end of the diaphragm pump body, and an outlet pipe is connected to the output end of the diaphragm pump body.

[0008] A four-way mechanism is connected between the water inlet pipe and the water outlet pipe, and a three-way mechanism is connected to one end of the four-way mechanism.

[0014] In one alternative: the stabilizing mechanism includes a positive and negative screw, which is rotatably mounted inside the mounting slot via a bearing. One end of the positive and negative screw passes through the base and is connected to a hexagonal block. The external threads of the positive and negative screw are connected to two clamping seats.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-6 As shown, a diaphragm pump with multi-point displacement function includes a base 1, a support frame 2 is provided on the top of the base 1, a diaphragm pump body 3 is provided on the top of the support frame 2, an inlet pipe 4 is connected to the input end of the diaphragm pump body 3, and an outlet pipe 5 is connected to the output end of the diaphragm pump body 3.

[0029] A four-way mechanism 6 is connected between the water inlet pipe 4 and the water outlet pipe 5, and a three-way mechanism 7 is connected to one end of the four-way mechanism 6.

[0030] In this embodiment, the diaphragm pump has the function of multi-point displacement through the cooperation of the four-way mechanism 6, the three-way mechanism 7, the rotary cylinder 8 and the controller 9. One pump can play the role of two pumps, effectively reducing the size of the entire equipment. The single pump design simplifies the pipeline layout, reduces equipment investment and maintenance costs, and at the same time reduces installation complexity and improves practicality.

[0031] In one embodiment, such as Figure 1 and Figure 5 As shown, the four-way mechanism 6 includes a four-way housing 61, with its two ends connected to the inlet pipe 4 and the outlet pipe 5, respectively. A four-way ball valve 62 is installed inside the four-way housing 61, with its input end penetrating the housing and extending to the outside. A first port 63 is provided on one side of the four-way housing 61. The three-way mechanism 7 includes a three-way housing 71, with one end connected to the four-way housing 61. A three-way ball valve 72 is installed inside the three-way housing 71, with its input end penetrating the housing and extending to the outside. A second port 73 and a third port 74 are provided on the outer sides of the three-way housing 71, respectively. Rotary cylinders 8 are connected to the input ends of both the three-way ball valve 72 and the four-way ball valve 62. A controller 9 is connected to the input ends of the two rotary cylinders 8. In the first mode, the diaphragm pump body 3 operates to... Liquid is drawn in at the second port 73, enters the four-way housing 61 through the three-way housing 71, then enters the diaphragm pump body 3 through the inlet pipe 4, and then enters the four-way housing 61 again through the outlet pipe 5. Finally, it is discharged through the first port 63. The controller 9 controls the operation of two rotary cylinders 8, which drive the four-way ball valve 62 and the three-way ball valve 72 to rotate, so that the diaphragm pump is in the second mode. The operation of the diaphragm pump body 3 causes liquid to be drawn in at the first port 63. The liquid enters the diaphragm pump body 3 through the inlet pipe 4, enters the diaphragm pump body 3 again through the outlet pipe 5, and finally enters the three-way housing 71 and is discharged through the third port 74. It has a multi-point displacement function, and one pump can perform the function of two pumps, effectively reducing the size of the entire equipment. The single pump design simplifies the pipeline layout, reduces equipment investment and maintenance costs, and reduces installation complexity.

[0032] In one embodiment, such as Figure 1 and Figure 3As shown, the top of the base 1 has a mounting groove 10, and a stabilizing mechanism 11 is provided inside the mounting groove 10. The stabilizing mechanism 11 includes a positive and negative screw 111, which is rotatably mounted inside the mounting groove 10 via bearings. One end of the positive and negative screw 111 passes through the base 1 and is connected to a hexagonal block 112. The external threads of the positive and negative screw 111 are connected to two clamping seats 113. Each of the two clamping seats 113 has a positioning groove 114 on its opposite side, and the positioning groove 114 is adapted to the support frame 2. The clamping seats 113 are connected to the support frame 2. The installation of the diaphragm pump body 3 is improved by the bolt 115 and the stabilizing mechanism 11. Even if the bolt 115 is loosened due to long-term operation vibration, the diaphragm pump body 3 will still work very stably. The diaphragm pump body 3 is placed on the top of the base 1. The hexagon block 112 is rotated by a tool. The hexagon block 112 drives the positive and negative screws 111 to rotate. The rotation of the positive and negative screws 111 causes the two clamping seats 113 to move closer to each other. The support frame 2 enters the positioning groove 114 until the clamping seat 113 can no longer move. Then, the clamping seat 113 and the support frame 2 are fixedly installed on the base 1 by the bolt 115.

[0033] In one embodiment, such as Figure 1 and Figure 4 As shown, a moving mechanism 12 is provided at each of the four corners of the bottom of the base 1. The moving mechanism 12 includes a universal wheel 121, which is located at the bottom of the base 1. A threaded sleeve 122 is fixedly connected to the bottom of the universal wheel 121. A threaded post 123 is threadedly connected inside the threaded sleeve 122. A knob 124 is fixedly connected to the bottom of the threaded post 123. A foot pad 125 is rotatably installed at the bottom of the knob 124. The moving mechanism 12 allows the diaphragm pump to be moved to one end over a short distance, making it easy to change the position of the diaphragm pump as needed. After moving to the designated position, the knob 124 is rotated, which drives the threaded post 123 to rotate, thereby changing the position of the foot pad 125 so that the foot pad 125 contacts the ground, effectively lifting the base 1 and improving the stability of the parking.

[0034] The above embodiment discloses a diaphragm pump with multi-point displacement function. The diaphragm pump body 3 is placed on the top of the base 1. The hexagon block 112 is rotated by a tool. The hexagon block 112 drives the positive and negative screws 111 to rotate. The rotation of the positive and negative screws 111 causes the two clamping seats 113 to move closer to each other. The support frame 2 enters the interior of the positioning groove 114 until the clamping seats 113 can no longer move. Then, the clamping seats 113 and the support frame 2 are fixedly installed on the base 1 by bolts 115. The port of the diaphragm pump is connected by a conduit.

[0035] In the first mode, the diaphragm pump body 3 operates, drawing liquid into the second port 73. The liquid enters the four-way housing 61 through the three-way housing 71, then enters the interior of the diaphragm pump body 3 through the inlet pipe 4, and then enters the interior of the four-way housing 61 again through the outlet pipe 5. Finally, it is discharged through the first port 63. The controller 9 controls the operation of two rotary cylinders 8, which respectively drive the four-way ball valve 62 and the three-way ball valve 72 to rotate, thus putting the diaphragm pump into the second mode. The diaphragm pump body 3 operates, drawing liquid into the first port 63. The liquid enters the interior of the diaphragm pump body 3 through the inlet pipe 4, and then enters the interior of the four-way housing 61 again through the outlet pipe 5. Finally, it enters the three-way housing 71 and is discharged through the third port 74. This mode has a multi-point displacement function, allowing one pump to perform the function of two pumps, effectively reducing the overall size of the equipment. The single-pump design simplifies the pipeline layout, reduces equipment investment and maintenance costs, and also reduces installation complexity.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
