Mechanical seal for circulating hot water pump of waste heat boiler. The characteristics of this kind of mechanical seal are: the dynamic and static ring seats are made of titanium metal, and its expansion coefficient is small, similar to that of carbonization, and it is easy to install the dynamic and static rings; the auxiliary seal adopts PTFE V-shaped sealing ring to ensure The followability of the dynamic and static rings at the working temperature; the self-flushing is used from the outlet liquid cooler, and the cooling high-pressure liquid is sent to the shaft seal box for flushing. Within the range, the problem of high temperature auxiliary sealing is solved. Among them, the heat transfer area of ​​the cooler is 1 square meter, the tube length is 23.3m, the circulating water volume is 6L/min, and the cooling water volume is 60L/min.

High temperature oil pump mechanical seal In petrochemical and oil refining equipment, the hot oil pumps with higher temperature are tower bottom hot oil pump, heat carrier pump, oil slurry pump, residual oil pump, wax oil pump, asphalt pump, molten sulfur and plasticizer pump. Wait.

In the high-temperature oil pump, the sealing pair adopts hard-to-hard to solve the sealing of the thermal oil pump at the bottom of the decompression tower containing solid particles at low pressure. The elastic element adopts welded metal bellows to solve the sealing of the thermal oil pump under different pressures, and adopts the shaft seal box cooling jacket to reduce The temperature is used to solve the hot oil pump seal, and the fin cooling shaft seal box is used to protect the auxiliary seal to solve the hot oil pump seal, and the double end face seal is adopted to strengthen the flushing and other measures.
