(1) First check the quality of the mechanical seal (whether there are scratches on the end faces of the dynamic and static rings).
(2) Wipe the O-ring of the moving ring and the foreign objects on the surface of the moving and static rings with a clean soft cloth, and apply a small amount of lubricating oil on the surface according to the use requirements of the medium in the tank.
(3) Recheck the levelness of the static ring of the mechanical seal and the verticality of the sealing section of the stirring shaft with a spirit level and a dial indicator, and correct them to the specified requirements.
(4) Install and fix the base of the mechanical seal and the fixing ring, and adjust the hexagonal set screws of the fixing ring on the stirring shaft, so that the spring of the mechanical seal is evenly stressed, and the end faces of the dynamic and static rings of the mechanical seal are tightly combined.
(5) If the balance tank is set on the frame as required, connect the pipeline of the inlet and outlet of the sealing liquid and the mechanical seal, connect the pipeline of the nitrogen bottle, the pressure reducer and the balance tank, and connect it after the static pressure test meets the requirements. Water jacket, through cooling water to wait for the whole machine to test.
(6) When the temperature of the medium in the glass-lined reaction tank is below 80 °C, add oil in the cooling tank for cooling, and the type of refueling should not affect the quality of the materials in the tank. Generally, it should have a high heat of vaporization, clean without any impurities, and have Good lubrication function. When the medium temperature is higher than 80℃, the bottom cooling water jacket and the cooling tank are cooled by circulating water.
