Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right.
Cooling tower pump type.
Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order.
This pump has a totally enclosed nonventilated tenv motor that is cooled by the liquid being pumped.
The sketch shown below explains about the spray type of cooling tower.
Their flow rate varies depending on the heat flow to be dissipated.
The spray header is located on top as shown in the sketch.
Warm water from the condenser is fed to the spray header by means of a pump.
Basic cooling tower equipment.
Air from the atmosphere comes in contact with the warm water thereby causing some.
Also known as a flexible impeller pump it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump.
The required head is determined by the type of cooling system.
Cooling water pumps are used for supplying heat exchangers with cooling water.
Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m.
Your chilled water system may even have more than one type of chill water pump with a primary pump circulating water through your chiller and another to circulating water through the building.
Some fairly catastrophic events can occur if either is improperly installed.
A distinction is made between wet cooling and dry cooling processes.
Natural draft cooling towers.
The cooling tower water circulating pumps are critical to the chiller systems they serve.
The axially split design allows easy removal of the top casing and access to the pump components bearings wear rings impeller and shaft seal without disturbing the motor or pipe work.
Piping condenser cooling tower losses and valves.
Plants commonly operate over the design capacity which means the cooling tower needs to keep up.
Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near.
For the tower piping circuit the pump must overcome the piping flow friction loss.
Air movement occurs due to differences in density between the entering air and the internal air within the tower.
The paco kp kpv kpvs split case pump is a single stage non self priming between bearing centrifugal volute pump.
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature.
Correctly piping the suction and discharge of your cooling tower condenser water pump is critical.
It is important to have some excess flow in the pump and tower design for these situations.
