Difference between normal temperature water pump and high temperature water pump
|
|
Commonly used pump refers to the transfer of 80 degrees C below the temperature of the liquid pump is called the cold water pump, 80 degrees C to 120 degrees C between the temperature of the pump called hot water pump.
The difference between the cold water pump and the hot water pump:
1, the cold water pump: seal packing seal or mechanical seal rubber material Ding Qing cold water pump commonly used, the most common packing pump is is single stage single suction centrifugal pump of the pump is also one of the earliest water pump products, because the filler itself requires liquid cooling and lubrication, so the pump temperature is highest it is only about 80 degrees, and the packing seal of water pump and water dripping phenomenon, there are certain pollution to the pump body pump base and the surrounding environment, this kind of product has been ISG and ISW centrifugal pump series products replaced, ISG and ISW series of cold water using mechanical seal it will not have Water Leakage phenomenon, and are the structure of the impeller is directly connected to the motor shaft, the vibration and noise of above is obviously better than that of the old type of is series cold water pump this kind of pump products commonly used in air conditioning water cycle with so called air conditioning Water circulating pump.
2, a hot water pump: pump hot water is in the ISG and ISW centrifugal pump series of based on optimization design and water pumps, especially IRG hot water circulating pump, the largest amount, because the pump with vertical installation motor in the upper, between the pump and the motor and a short support, not because the mechanical seal leakage phenomenon caused motor inside the water inlet of burn out the motor, but also can be in IRG hot water pump based on the designed maximum temperature in the high temperature hot water pump products also rely on external water cooling device of the mechanical seal can reach 240 degrees. |
