Description

Technical Field

[0001] The utility model relates to a diaphragm pump technology, in particular to a diaphragm pump. Background Art

[0002] Diaphragm pumps, also known as control pumps, are a primary type of actuator. They receive control signals from a control unit and utilize power to vary fluid flow. Their role in the control process is to receive control signals from a regulator or computer, altering the flow of the regulated medium to maintain the regulated parameter within the desired range, thereby automating the production process. Regulating and controlling process parameters such as temperature, pressure, flow, and liquid level requires a diaphragm pump.

[0003] A diaphragm pump consists primarily of a transmission unit and a diaphragm head. The transmission unit is the driving mechanism that drives the diaphragm back and forth, while the diaphragm head primarily transports gas and is separated from the transmission unit by the diaphragm. Currently, the transmission unit of a diaphragm pump is primarily driven by powering a coil. However, when the coil is energized, the entire pump body vibrates violently, causing various components of the diaphragm pump to loosen, resulting in a decrease in sealing performance and even damage to the pump body.

[0023] Example 1:

[0024] like Figure 1-3As shown, a diaphragm pump is connected to a pump body and fixed to a bracket, comprising a pump head 1, with mounting brackets 5 on both sides of the pump head 1, the mounting brackets 5 comprising vertical plates and bottom plates, the vertical plates being vertically arranged on both sides of the pump head 1, the vertical plates being provided with through holes 6, guide rods being passed through the through holes 6, springs being sleeved on the guide rods, the bottom plate being horizontally arranged at the bottom of the vertical plate, an upper cushion 8 being provided above the bottom plate, a lower cushion 7 being provided below the bottom plate, and the bottom plate and the guide rods being fixed to the bracket.

[0025] The upper cushion 8 and the lower cushion 7 are both silicone cushions.

[0026] The diaphragm pump of this embodiment is provided with an upper cushion 8 and a lower cushion 7 at the connection between the mounting frame 5 and the bracket, which effectively reduces the vibration amplitude of the pump head 1 and the pump body. By setting the spring, the mounting frame 5 and the guide rod, the position of the top of the pump head 1 can be fixed, and the top of the pump head 1 can be cushioned, further reducing the vibration amplitude of the pump head 1 and the pump body, protecting the pump head 1 and the pump body, and improving the service life of the diaphragm pump.

[0027] The pump head 1 is provided with a rotary sleeve 4 , which is threadedly engaged with the outer wall of the pump head 1 , and is used to fix the pump head 1 and the pump body.

[0028] A pump diaphragm cavity is provided in the pump head 1, and a mounting column 2 is provided on one side of the pump head 1. An air inlet 12 and an air outlet 13 are provided on the mounting column 2, and the air inlet 12 and the air outlet 13 are both connected to the pump diaphragm cavity; an air intake arrow and an air exhaust arrow are respectively provided on both sides of the top surface of the mounting column 2, and the air intake arrow is located directly above the air inlet 12, and the air exhaust arrow is located directly above the exhaust port; the air inlet 12 is connected to the air inlet pipe, and the air outlet 13 is connected to the air outlet pipe.

[0029] A baffle 3 is fixed to the end of the mounting column, and the baffle 3 is fixed to the mounting column 2 by a fixing pin. Air holes 11 are provided on both sides of the baffle 3, and an arc-shaped baffle is provided on the air hole 11. The diameter of the air inlet 12 is larger than the diameter of the baffle, and the diameter of the baffle is larger than the diameter of the air outlet 13;

[0030] The baffle is a rubber sheet. When air is taken in, the diaphragm moves upward, and negative pressure is formed in the pump membrane cavity. The two baffles move toward the air outlet 13 and the air inlet 12 respectively. Since the baffle diameter is larger than the diameter of the air outlet 13, the air outlet 13 is blocked by the baffle to prevent the air outlet 13 from sucking back gas from the air outlet pipe, and the diameter of the air inlet 12 is larger than the baffle diameter, the air inlet 12 can take in air smoothly. When air is discharged, the diaphragm moves downward, and high pressure is formed in the pump membrane cavity. The gas in the pump membrane cavity is pushed outward. At this time, the air outlet 13 is opened and connected to the air outlet pipe, and the baffle at the air inlet 12 moves outward to block the air inlet pipe, preventing the gas from flowing back to the air inlet pipe, thereby achieving exhaust. The above operations are repeated to achieve gas pumping.

[0031] A groove is provided on the top of the lower cushion 7, the bottom plate is located in the groove, the bottom plate is provided with a hole groove, a buffer ring is passed through the hole groove, the buffer ring is fixed under the upper cushion 8, and a bolt 10 is passed through the buffer ring. The bolt 10 passes through the bracket, lower cushion 7, bottom plate and upper cushion 8 in sequence and then engages with the nut 9 threadedly; the arrangement of the groove and the buffer ring can wrap the bottom plate so that vibrations in all directions can be buffered.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
