Cooling Tower Pump Type
This pump has a totally enclosed nonventilated tenv motor that is cooled by the liquid being pumped.
Cooling tower pump type. A distinction is made between wet cooling and dry cooling processes. The cooling tower water circulating pumps are critical to the chiller systems they serve. Natural draft cooling towers. The spray nozzles spray the warm water inside the tower.
It must also provide the energy head necessary to raise water from a low to a higher static head level. The required head is determined by the type of cooling system. Plants commonly operate over the design capacity which means the cooling tower needs to keep up. Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right.
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. As their name implies natural draft cooling towers rely on natural convection to circulate air throughout the tower which then cools the water. Air movement occurs due to differences in density between the entering air and the internal air within the tower. The sketch shown below explains about the spray type of cooling tower.
Correctly piping the suction and discharge of your cooling tower condenser water pump is critical. The spray header is located on top as shown in the sketch. The paco kp kpv kpvs split case pump is a single stage non self priming between bearing centrifugal volute pump. 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.
Piping condenser cooling tower losses and valves. It is important to have some excess flow in the pump and tower design for these situations. Their flow rate varies depending on the heat flow to be dissipated. For the tower piping circuit the pump must overcome the piping flow friction loss.
Air from the atmosphere comes in contact with the warm water thereby causing some. Some fairly catastrophic events can occur if either is improperly installed. Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order. Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m.
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. Basic cooling tower equipment. 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.
