Cooling Tower Pump Type

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.

Cooling tower pump type.

The spray nozzles spray the warm water inside the tower. The required head is determined by the type of cooling system. Natural draft cooling towers. Their flow rate varies depending on the heat flow to be dissipated.

Basic cooling tower equipment. Air movement occurs due to differences in density between the entering air and the internal air within the tower. Warm water from the condenser is fed to the spray header by means of a pump. The spray header is located on top as shown in the sketch.

Some fairly catastrophic events can occur if either is improperly installed. Correctly piping the suction and discharge of your cooling tower condenser water pump is critical. As their name implies natural draft cooling towers rely on natural convection to circulate air throughout the tower which then cools the water. Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m.

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. Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order. It must also provide the energy head necessary to raise water from a low to a higher static head level. This pump has a totally enclosed nonventilated tenv motor that is cooled by the liquid being pumped.

Plants commonly operate over the design capacity which means the cooling tower needs to keep up. The cooling tower water circulating pumps are critical to the chiller systems they serve. The sketch shown below explains about the spray type of cooling tower. It is important to have some excess flow in the pump and tower design for these situations.

Piping condenser cooling tower losses and valves. For the tower piping circuit the pump must overcome the piping flow friction loss. Cooling water pumps are used for supplying heat exchangers with cooling water. Air from the atmosphere comes in contact with the warm water thereby causing some.

Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right. 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. A distinction is made between wet cooling and dry cooling processes.
