Chemical pump at high temperature cooling needs

Chemical pump cooling needs in high temperature cooling purposes: ① reduce the seal chamber temperature of the medium. ② reduce heat, prevent impurities precipitation. ③ prevent the medium from vaporization, crystallization. ④ Collect leakage of media to prevent pollution. Cooling needs at different temperatures: ①, when the chemical pump conveying medium temperature <120 ℃, relying on its own medium to cool, no need to set up a separate cooling system. ② When 120 ℃ ≤ chemical pump conveying medium temperature <300 ℃, you must set the cooling chamber on the chemical pump cover, in the sealed chamber must also be introduced coolant, and with a double-sided mechanical seal. And when the medium has the cleanliness requirement, does not allow the coolant to infiltrate the medium, then it can be cooled by the simple heat exchanger, and then it is connected as the coolant. ③ When the temperature of the chemical pump is higher than 300 ℃, not only the cooling device must be installed in the pump head of the chemical pump, but also the cooling system should be installed in the suspension bearing chamber. The structure of the chemical pump needs to adopt the central support form, The material is the best choice of metal bellows.
