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 complex composition, 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. Multi-purpose pneumatic diaphragm pump working principle 1, compressed air for power. 2, is a volumetric displacement pump caused by the reciprocating deformation of the diaphragm, and its working principle is similar to the piston pump. Due to the working principle of the diaphragm pump, the diaphragm pump has the following features: (1) The pump will not overheat: compressed air For power, when 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 and how to spit out at work, so the material agitation is minimal, which is suitable for the transportation of unstable materials. (5) flow rate can be adjusted at the exit of the material to install a throttle to regulate the 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) 100% energy utilization, shut down the outlet, the pump automatically shut down, the device moves, wear, overload, fever phenomenon, when the outlet is open, the pump automatically boot. (15) There is no dynamic seal, easy maintenance to avoid leakage. No dead spots at work. Multi-purpose pneumatic diaphragm pump operation and operation precautions 1, to ensure that the maximum particles contained in the fluid does not exceed the maximum safety of the pump through the particle diameter standard 2, the inlet pressure should not exceed the maximum allowable pressure of the pump, compressed air higher than the rated pressure may Cause personal injury and property damage and damage to pump performance. 3, to ensure that the pump pressure piping system can withstand the highest output pressure to ensure that the drive air system clean and normal working conditions. 4. Electrostatic sparks may cause personal injury and property damage due to explosion. Use wires with enough large cross-section to properly ground the grounding screws on the pump. 5, grounding requirements in line with local laws and regulations and site requirements of some special requirements. 6, fasten the pump and the connection pipe joints to prevent electrostatic sparks due to vibration impact. Use antistatic hose. 7, to periodically check and test the reliability of the grounding system, grounding resistance requirements of less than 100 ohms. 8, to maintain good exhaust and ventilation, away from flammable and heat sources. 9, the pump exhaust may contain solids, do not face the work area or exhaust port, so as to avoid personal injury. 10, when the diaphragm failure, the delivery of materials from the exhaust muffler squirting. 11, When transporting flammable and toxic fluids, please connect the outlet to a safe place away from the work area. 12, Please use at least 3/8 "inner diameter smooth wall pipe connection exhaust and muffler. 13, high pressure fluid can cause serious personal injury and property damage, please do not pump the pressure and the pump System to carry out any maintenance work, such as to be repaired, first cut off the pump intake, open the bypass pressure relief mechanism to relieve the pressure piping system, slowly loosen the connection of the pipe joints. Toxic fluid pump, please do not pump directly to the manufacturer to repair. Properly handled according to local laws and regulations, and the use of Wenzhou in the pump valve genuine parts to ensure that the service life. 15, liquid delivery part of the use of aluminum alloy pump, please Do not use to transport fluids containing Fe3 + and halogenated hydrocarbons and other halogenated hydrocarbon solvents, corrosion of the pump body will result in bursting of the pump body. 16, Ensure that all parts that come into contact with the delivery body are not corroded by the fluid being transported. 17, to ensure that all operators are familiar with the operation and use of the pump to understand the safety precautions, if necessary, rationing the necessary protective equipment 18, the proper use of pumps, Allow prolonged idling.
Intergrated Solar Street Light
Intergrated Solar Street Light means the Solar Panel and head of light are intergraged together,just show as two opposite sides.
the advantage contains :no need to lay cables and ac power supply,just supply the power with sunlight,in case of no electricity charges; DC power supply,photosensitive control.
