Pneumatic diaphragm pump installation process: 1, pneumatic diaphragm pump installation and start: the diaphragm pump placed as close to the product where possible, the suction pipe line shortest, reducing the number of configuration components, not to reduce the pipe size. To extend the life of the diaphragm, keep the pump as close as possible to the fluid being pumped and require a slow pressure adjustment mechanism to extend the diaphragm life at inlet pressures in excess of 10 feet (3 meters). If hard piping is installed, use a short hose between the pump and the piping. Hoses can slow pipe vibrations and distortions, and a surge tank is recommended to further reduce the pulses in the fluid. 2, to the diaphragm pump gas supply: metal diaphragm pump supply pressure shall not exceed 125PSI (8.6BAR), plastic pump supply pressure shall not exceed 100PSI (6.9BAR). Connect the air inlet of the pump to the air supply with enough capacity and pressure to meet the design requirements. If the air supply line is a hard pipe, connect a short hose between the pump and the pipe to reduce distortion. In addition to the air inlet cap, the air intake pipe, the pressure regulator filter weight must also be supported by some means. Failure to support the pipe may damage the pump. Pressure regulators must be installed to ensure that the supply pressure does not exceed the specified range. 3, the diaphragm pump before the operation check: diaphragm pump work, prosecute all ** fixtures to prevent relaxation, tighten the loose place to avoid leakage, with the pump attached to the card described in the method of fixing. 4, diaphragm pump intake and start: start, the air valve open about 1/2 to 3/4 laps. After the pump is started, open the air valve to increase air flow to achieve the required flow rate. 5, pneumatic diaphragm pump exhaust: If the diaphragm is broken, the extracted liquid or gas will enter the pump air port, was discharged into the atmosphere, when the extraction of dangerous or toxic substances, the need to pipe to the appropriate place for safe handling . If the pump sink into the liquid work, the gas to be discharged from the liquid level, the exhaust pipe can not be less than 1 "(2.45CM) .Decreasing the exhaust pipe size will limit the gas flow, reducing pump usage .When the material level is high In the pump, the discharge outlet should be at a higher place to prevent siphon phenomenon.Under a certain temperature and humidity, the discharge of gas may freeze up, the use of gas drying can eliminate most of these problems. 6, pneumatic diaphragm Pump after use: If used to transport easily curable materials, to prevent damage to the pump, thoroughly clean the pump after each use (after use, the product left in the pump has dried or stuck to the pump, so Will cause problems with diaphragm and valve before next start-up.) At freezing temperatures, the pump must be drained dry after any use. 3. Notes on Valve Lubrication: Air Distribution Valves and Guided Valves are designed with no oil, which is the ideal working condition.In some cases, such as personal hobby or air quality is very poor, but also on the supply of compressed air Run , Compressed air supply system is properly lubricated, the pump air system industry can work with appropriate lubrication requires the use of an air line lubricator set to pump the air every 20SCFM deliver a drop of non-detergent oil, you can check the pump Performance curve open quantitative.Pneumatic diaphragm pump feed pipe generally do not install the valve, the direct election Diaphragm and diaphragm pump on the tube, pay attention to the feeding tube to have a certain intensity, or tube will be deflated work, affecting the feed Generally in the discharge pipe plus a valve to see the scene conditions, is installed manual valve or automatic valve.Pipeline, valve selection should pay attention to the material properties (such as pH, corrosivity, etc.) to match. General to install triple (pressure regulating, drainage, lubrication), the general import pump without lubricating oil. Ball valve, flow control valve (optional). If the demanding occasions also require the installation of regulators, pressure gauges, leak detection Instrument, etc .. Such as the installation of solenoid valves, metering controllers, but also the diaphragm pump into a metering pump, for remote control feeding.
