After we have purchased a one-way pneumatic diaphragm pump, there may be a repair guide in its package, but maybe we usually ignore it during use, so Xiao Bian will introduce you here Look at the terms in its service guide. A / Piston: aluminum cylinder enclosed in air valve to control air flow B / air valve: plastic or metal valve housing is fixed by four screws on the center of the pneumatic one-way diaphragm pump C / static discharge head: from pneumatic Vertical distance (in meters) from unidirectional diaphragm pump centerline to free delivery point D / Cavitation: Pump discharge below nominal due to reduced or lack of fluid supplied at pump inlet In fact, E / Specific Gravity: The ratio of fluid weight to water weight at 4 degrees, the specific gravity of 4 degrees water is 1.0, the static suction head --- the vertical distance from the feed liquid level to the pump center line, the pump should be at Above the fluid level F / Inlet pressure: Inlet is measured in Bar, including the specific gravity and flow rate of the fluid H / Vapor pressure: All liquids produce pressure on their free surface steam In any pump operating system, the operating pressure can not Below the vapor pressure or steam will partially or completely cut off into the pump fluid G / water hammer effect: a higher inlet to form a static pressure head on the pump to produce internal pressure I / viscosity: Due to the presence of fluid internal friction, This property of viscosity gives fluid flow resistance.
