Complete System Installation Schematic
1. Air Source Treatment Unit
Filter Regulator ②: Filters impurities and moisture in compressed air first, then regulates and stabilizes the air pressure supplied to the pump.
Dryer ③: Further removes moisture from compressed air to prevent water vapor from entering the pump chamber and causing internal component corrosion and icing.
Lubricator ④: Atomizes lubricating oil and mixes it into compressed air to lubricate moving parts such as pneumatic valves and diaphragms of the pump and reduce wear.
Supporting components: Air Inlet, Check Valve, Shut-Off Valve.
2. Pump Body and Exhaust System
Pump Body: The core pneumatic diaphragm pump, which drives the diaphragm to move back and forth via compressed air to realize fluid suction and discharge.
Muffler: Installed at the pump exhaust port to reduce exhaust noise.
Piped Exhaust: Discharges waste gas to a safe area to avoid workshop environmental pollution.
Flexible Connection: A flexible connection between the pump and the air source treatment unit to buffer vibration and reduce stress transmission.
3. Fluid Suction Pipeline (Left Side of the Figure)
Suction: The starting point for fluid entering the system, connected to upstream liquid storage tanks or pipelines.
Shut-Off Valve: Cuts off fluid suction for convenient pump maintenance.
Compound Gauge: Monitors suction-side pressure to identify issues such as insufficient suction lift and pipeline blockage.
Flexible Connector: Absorbs pump vibration and prevents stress damage caused by rigid pipeline connection.
Drain Port: Drains residual liquid in the suction pipeline for maintenance or pipeline emptying.
Pipe Connection: Multiple connection types are optional to adapt to on-site pipeline conditions.
4. Fluid Discharge Pipeline (Right Side of the Figure)
Flexible Connector: Buffers pump vibration to protect pipelines and equipment.
Pipe Connection: Consistent with the suction end, adaptable to on-site pipelines.
Drain Port: Drains residual liquid in the discharge pipeline for maintenance and emptying.
Surge Suppressor ①: Stabilizes the pulsating discharge pressure of pneumatic diaphragm pumps and protects pipelines and downstream equipment, serving as a key accessory on the discharge side.
Pressure Gauge: Monitors discharge-side pressure to judge the operating status of the pump.
Shut-Off Valve: Cuts off fluid discharge to facilitate maintenance of the pump and downstream equipment.
Discharge: The terminal outlet of the system, connected to downstream pipelines and equipment.
Unregulated Air Supply to Surge Suppressor: Directly supplies unregulated compressed air to the surge suppressor, utilizing the compressibility of gas to absorb fluid pulsation.
