1、 Overview:
Lined with fluorinePneumatic diaphragm pump is a new type of conveying machinery and is currently one of the most innovative pump types in China. Using compressed air as the power source, it can extract and absorb various corrosive liquids, particulate liquids, high viscosity, volatile, flammable, and highly toxic liquids.
Fluorine lined pneumatic diaphragm pumps are made of two materials: perfluorinated and fluorine lined. Diaphragm pumps use nitrile rubber, polytetrafluoroethylene, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. Placed in various special occasions for pumping media that conventional pumps cannot pump, satisfactory results have been achieved.
2、 Applicable occasions:
Due to the above characteristics of pneumatic diaphragm pumps, diaphragm pumps have gradually entered the market of other pumps and occupied a part of it since their birth in the world. For example, diaphragm pumps have taken an absolute dominant position in the paint and ceramic industries, while in other industries such as environmental protection, wastewater treatment, construction, sewage, and fine chemicals, they are expanding their market share and have an irreplaceable position compared to other pumps. The advantages of pneumatic diaphragm pumps are:
1. Due to the use of air as a power source, the flow rate automatically adjusts with changes in back pressure (outlet resistance), making it suitable for fluids with medium to high viscosity. The working point of a centrifugal pump is set based on water. If it is used for fluids with slightly higher viscosity, it needs to be matched with a reducer or frequency converter, which greatly increases the cost. The same applies to gear pumps.
2. The use of pneumatic pumps in flammable and explosive environments is reliable and cost-effective, such as the transportation of fuel, gunpowder, and explosives, because: firstly, sparks cannot be generated after grounding; Secondly, there is no heat generated during work, and the machine will not overheat; Thirdly, the fluid will not overheat because the diaphragm pump has minimal agitation on the fluid.
3. In harsh areas of construction sites, such as construction sites and industrial and mining wastewater discharge, due to the high impurities and complex composition in the sewage, the pipelines are prone to blockage, which leads to excessive load on the electric pump and makes the motor vulnerable to heating. Pneumatic diaphragm pumps can pass particles and have adjustable flow rates, automatically stopping until unobstructed when the pipeline is blocked.
4. In addition, the diaphragm pump has a small volume, is easy to move, does not require a foundation, occupies a very small area, and is easy and economical to install. Can be used as a mobile material conveying pump.
5. In the handling of hazardous and corrosive materials, diaphragm pumps can completely isolate the materials from the outside world.
6. Or ensure that there are no impurities contaminating the raw materials in some experiments.
7. Can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculants, etc. This is because the shear force of the diaphragm pump is low and has little physical impact on the material.

3、 Working principle:
1、Powered by compressed air.
2. In each of the two symmetrical working chambers of the pump, there is an elastic diaphragm installed. The connecting rod integrates the two diaphragms into one. Compressed air enters the distribution valve from the pump's inlet joint and pushes the diaphragms in the two working chambers, driving the two diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged out of the pump from behind the diaphragm. Once reaching the end of the journey. The valve mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm in the opposite direction, thus forming synchronous reciprocating motion of the two diaphragms. There are two one-way ball valves installed in each working chamber. The reciprocating motion of the diaphragm causes a change in the volume of the working chamber, forcing the two one-way ball valves to alternately open and close, thereby continuously inhaling and discharging liquid.

Therefore, diaphragm pumps have the following characteristics:
(1) The pump will not overheat: compressed air is used as the power source, and during exhaust, it is a process of expansion and heat absorption. The temperature of the pneumatic pump decreases during operation, and no harmful gases are discharged.
(2) No electric sparks generated: Pneumatic diaphragm pumps do not use electricity as power and are grounded to prevent static sparks
(3) It can be achieved through liquid containing particles: because it works in a volumetric manner and the inlet is a ball valve, it is not easily blocked.
(4) Extremely low shear force on materials: how to suck in and how to spit out during operation, so minimal agitation on materials, suitable for conveying unstable substances
(5) The flow rate can be adjusted by installing a throttle valve at the material outlet.
(6) It has the function of self-priming.
(7) It can run empty without any danger.
(8) Can work underwater.
(9) The fluids that can be transported are extremely diverse, ranging from low viscosity to high viscosity, and from corrosive to viscous.
(10) There is no complex control system, no cables, fuses, etc.
(11) Small in size, lightweight, and easy to move.
(12) No lubrication is required, so maintenance is simple and there will be no pollution to the working environment due to dripping.
(13) The pump can always maintain high efficiency and will not decrease due to wear and tear.
(14) 100% energy utilization, when the outlet is closed, the pump automatically stops, causing equipment movement, wear, overload, and heating
(15) Without a dynamic seal, maintenance is easy and leakage is avoided. There are no dead spots during work.
