Question:

How high is the maximum temperature of the seal water in the pump?

How high is the maximum temperature of the seal water in the pump?

Answer:

This medium temperature is not certain, mainly depends on what kind of water pump used, what material?.Ordinary water pump shaft seal temperature is generally below 70 degrees C, chemical pumps, hot water pump seals can work in 70-120, 120-180, 180-230 between the work, the specific requirements of the material is different.If you are asking about the temperature of the shaft seal circulating cooling water, please do not exceed 35 degrees of temperature, otherwise it will affect the service life of the shaft seal.
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
The maximum temperature of water seal pump is 60 degrees. Water pump shaft seal is rarely used mechanical seals, most of the use of packing seal. If it is mechanical seal, this pump should be said that it is not suitable for long-term work at 60 degrees or more, because there are some rubber materials in the mechanical seal, these rubber materials work over 60 degrees for a long time, it is easy to aging and cracking. In addition, the mechanical seal in actual use, the amount of heat itself is not as serious as you think. General hand inspection, can not feel the temperature difference with other parts of the obvious. General rubber work limit temperature, that is, around 60 degrees.
