How to make the diaphragm pump outlet pressure and flow stability?

How to make the diaphragm aluminum pump outlet pressure and flow stability:

Abstract: in order to make the pneumatic diaphragm pump has a stable work pressure, flow rate, the import and export of pump pipe have a buffer tank.Buffer tank with nitrogen prefi lled certain pressure, prefi lled in principle not low pressure In 30% of the maximum working pressure and higher than 80% of the minimum working pressure.

In order to make the pneumatic diaphragm pump has a stable work pressure, flow, import and export of pipe of the pump set has a buffer tank.Buffer tank with nitrogen prefi lled certain pressure, the work of filling pressure in principle cannot under the big pressure of 30% and higher than 80% of the minimum working pressure.Although higher prefi lled pressure can produce good buffer effect, but when the pressure drop generates a pulse, frequent shock at the bottom of the tank and cause gold belongs to the internal parts damaged.

When work pressure range is bigger, need only prefi lled pressure to 30% ~ 35% of the maximum working pressure diaphragm plastic pump manufacturers provide early filling pressure is: import buffer tank prefi lled pressure to 80% ~ 90% of inlet pressure, outlet buffer tank prefi lled pressure and outlet pressure of 60% ~ 65%.In the actual operation, the diaphragm pump inlet pipe vibration is big, that import buffer tank pre filling pressure is not appropriate, according to the actual situation, put into the mouth of the buffer tank prefi lled pressure down to 60% ~ 65% of inlet pressure, vibration immediately eliminated, pump back to normal working condition.
