Pneumatic diaphragm Pump works and occasions Pneumatic diaphragm pump is a new type of conveyor, is currently the most novel kind of pump. The use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted. Pneumatic diaphragm pump has four materials: plastic, aluminum, cast iron, stainless steel. Diaphragm pumps are based on different liquid medium were nitrile rubber, neoprene, fluorine rubber, PTFE, polyhexamethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a conventional pump can not be aspirated medium, have achieved satisfactory results. First, the working principle of pneumatic diaphragm pump 1, compressed air as power. 2, is a volumetric displacement pump caused by the reciprocating deformation of the diaphragm. The working principle of the diaphragm pump is similar to that of the piston pump. Due to the working principle of the diaphragm pump, the diaphragm pump has the following features: (1) The pump can not overheat: Air-powered, in the exhaust is an expansion of endothermic process, pneumatic pump temperature is reduced, no harmful gas emissions. (2) does not produce spark: pneumatic diaphragm pump without electricity as power, grounding and then prevent the static spark (3) can contain particles of liquid: because the volume of work and imports for the ball valve, so it is not easy to be blocked. (4) Extremely low shear force on the material: How to suck in the work and how to spit it out, so the material agitation is minimal, which is suitable for the transportation of unstable substances (5) The flow rate can be adjusted, and the section can be installed at the exit of the material Flow valve to regulate flow. (6) Self-priming function. (7) Can be air operated without danger. (8) can dive work. (9) The fluids that can be delivered are extremely wide, ranging from low viscosity to high viscosity, from corrosive to viscous. (10) There is no complicated control system, no cables, fuses and so on. (11) small size, light weight, easy to move. (12) Maintenance is easy without lubrication, and will not pollute the work environment due to drip. (13) The pump is always efficient and will not be reduced by wear. (14) One hundred percent energy utilization, shut down the outlet, the pump automatically shut down, the device moves, wear, overload, fever (15) no dynamic seal, easy maintenance to avoid leakage. No dead spots at work. Second, the application of pneumatic diaphragm pump pneumatic diaphragm pump with the above characteristics, so in the world since the birth of the diaphragm pump is gradually invaded other pump market, and occupy part of them. Such as: paint, diaphragm pumps in the ceramic industry has occupied an absolute dominance, while in other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemicals is expanding its market share, and has other pumps irreplaceable Position. Pneumatic diaphragm pump has the following advantages: 1, due to the use of air as power, so the flow rate with the back pressure (outlet resistance) changes automatically adjusted for the viscosity of the fluid. Centrifugal Pump operating point is set on the basis of water, if used for slightly higher viscosity fluid, you need to support reducer or inverter, the cost has greatly improved, the same is true of the gear pump. 2, in a flammable and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder, explosives, because: First, the ground is not likely to spark; second, no heat during work, the machine is not Will overheat; thirdly, the fluid will not overheat because the diaphragm pump agitates the fluid to a minimum. 3, poor construction sites, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and the composition of complex, easy to plug the pipeline, so the formation of the pump on the load is too high, the motor heat vulnerable. Pneumatic diaphragm pump through the particles and the flow rate can be adjusted, the pipeline automatically stop blocked to patency. 4, the other diaphragm pump is small and easy to move, do not need the foundation, accounting for the ground is extremely small, easy and economical installation. Can be used as mobile material transfer pump. 5, in a hazardous, corrosive material handling, diaphragm pump can be completely separated from the outside world. 6, or some experiments to ensure that no impurities pollute the raw materials. 7, can be used to transport the chemical properties of relatively unstable fluids, such as: photographic materials, flocculation and so on. This is because diaphragm pumps have low shear forces and little physical impact on the material.
According to different hammer head shapes, hammers can be divided into ball pein hammers, sledge hammers, etc. According to different hammer head materials, they can be divided into carbon steel hammers, wood hammers rubber hammers, plastic hammers.
The specifications of the hammer are generally expressed by its mass, and commonly used are 0.25kg, 0.5kg and lkg.
