Description
Technical Field
The utility model relates to a diaphragm pump technical field specifically is a novel radial motion diaphragm pump.
Background
The diaphragm pump is actually a plunger pump, and the plunger and the pump cylinder are protected by separating the infused liquid from the plunger and the pump cylinder through a film. The left side of the diaphragm is made of corrosion-resistant material or coated with a layer of corrosion-resistant material, and the right side of the diaphragm is filled with water or oil. Diaphragm pumps, also known as control pumps, are the main type of actuator that is operated by power to vary the fluid flow by receiving a control signal from a regulating control unit. The diaphragm pump is used in the control process to receive the control signal of the regulator or the computer and change the flow rate of the regulated medium to maintain the regulated parameters in the required range, so as to realize the automation of the production process. If the automatic adjustment system is compared to a manual adjustment process, the detection unit is the human eye and the adjustment control unit is the human brain, the execution units-membrane pumps are the human hand and foot. The diaphragm pump is not required to be opened to realize the adjustment and control of certain parameters of the process, such as temperature, pressure, flow, liquid level and the like.
The traditional diaphragm pump adopts axial reciprocating motion, and the noise is large.
