Diaphragm pumps are a form of positive displacement pump that contains rotating elements. These pumps use their reciprocating sections to form a temporary chamber, taking in and expelling liquids via the pump to provide steady fluid flow. In this blog, we’ll provide you with a brief overview of various components of Diaphragm Pump and more.
Diaphragm Pump
They are the most common pumps used in a variety of sectors and they can easily handle a wide range of fluids. They provide reliable and regular fluid flow to handle chemicals, solvents, viscous or sticky fluids, polluted water, and much more with ease. This is the reason that these instruments are mostly used for fluid handling and processing applications in a wide range of industries. They are food and beverages, water, and wastewater treatment, construction, chemical processing, oil, and gas, mining, and many others.
The Different Components of the Diaphragm Pump and Their Working
To know about diaphragm pump working, it is important to know that they use positive displacement. They use a combination of the reciprocating action of two flexible diaphragms, as well as two inlet and output ball check valves To pump a fluid. These two pump chambers are separated by diaphragms into air and fluid zones.
The two diaphragms are linked to a common shaft in the central part. During a cycle, one side pumps fluid while the other fills. As the common shaft in the center part moves to the right, the diaphragm in the left chamber moves toward the center. This movement creates a vacuum on the left diaphragm’s liquid side, which lifts the lower ball check valve and allows liquid to flow into the liquid chamber via the suction manifold.
At the same moment, any fluid in the right chamber is drained.
The air distribution system is there to recognize when the diaphragm in the right chamber has finished its discharge stroke and adjusts the common shaft. This causes the diaphragm to shift to the left, pressurizing the liquid and lifting the top ball check valve. This makes fluid to flow through the discharge manifold and out of the pump.
Some Other Components of Diaphragm Pump
Manifolds
Manifolds are pipes that connect numerous pumping units to provide a single suction and delivery line, simplifying installation.
Fittings
Fittings Both manifolds have a straight or curved hose tail that connects the pump to the machine circuit.
Safety valve
A safety (or pressure relief) valve is designed to mitigate the effects of overpressure on the supply line.
PTO guards
PTO guards protect operators and others from rotational components that provide a significant safety risk.
Oil compensator
The oil compensator is a transparent receptacle filled with lubricating oil and attached to the crankcase’s oil bath. The oil compensator is used to ensure that the oil level is correct and, if necessary, refill it.
Pressure accumulator (or pulsation dampener)
The pressure accumulator is used to lessen or eliminate pulsations, prevent potential pipe pounding, lower the burden on the pump, and reduce noise; as a result, pumps will wear less and last longer.
To Finish
The diverse range of Diaphragm pumps can handle a wide range of chemicals, flow rates, and viscosities with ease. This is the reason, these pumps are chosen in various industries. After reading this blog, hope that it will be easier for you to select the appropriate pump for your application.
