Pneumatic diaphragm membrane rupture has been trapped around the user? The following Shanghai Yiling pump technology, after a long period of use of the experience to tell how to extend the use of the diaphragm as far as possible, through experimental analysis that the improvement of the diaphragm diaphragm gland pneumatic diaphragm can effectively increase the service life of the small Of the improvement on the durability of the diaphragm is essential; the use of the fact that the process has proved that the gland with curvature is indeed valid, of course, reasonable maintenance, the right to use can also effectively extend the life of the diaphragm, for example, when the pneumatic diaphragm pump easy to coagulate, easy It is a good practice to have an effective cleaning of the bonded material, or the air pressure can be properly adjusted according to the desired flow rate. This will also extend the useful life of the diaphragm.
According to the needs of the market Yiling Pump developed QBY-type diaphragm pump products, the first specification is DN25 caliber reference design after the German diaphragm operation of the diaphragm pump is normal, but after many experiments diaphragm fatigue resistance no more than 200 million Because the diaphragm in the pump to reciprocate at a fast speed, especially when the gas pressure at 0.7MPa, the reciprocation frequency of 145 times per minute. In general the actual use of reciprocating frequency of 30 to 60 beats per minute. To improve the fatigue life of the diaphragm must minimize the diaphragm stress concentration, so proceed from the diaphragm shape (does not affect the diaphragm installation) the waveform diaphragm waveform radius as much as possible, all the transition fillet also try to increase.Secondly from Diaphragm material rubber raw materials imported rubber, cord fabric using a special model, the curing process to strictly control each process to ensure that the strict control of the manufacture of 10 samples. Diaphragm pump products are stainless steel pneumatic diaphragm pumps, electric diaphragm pumps, pneumatic diaphragm pumps, Plastic diaphragm pumps, aluminum diaphragm pumps, miniature diaphragm pumps.
