Three pumps in the normal operation of the screw may occur during this or that fault, and today we talk about the three screw pump leak What are the reasons? What to do. Three screw pump one or three screw pump leakage reasons 1, taking the time, cavitation or longer pressure, resulting in seal damage; 2, the actual output of the pump is small, a large number of medium pump cycle, heat accumulation, causing the medium gasification , Resulting in seal failure; 3, return flow is too large, resulting in inhalation tube side of the container (tower, kettle, tank, pool) at the bottom of sediment damage, damage to seal; 4, for a long time outage, restart without manual disk Car, friction due to adhesion and tear the sealing surface; 5, the medium corrosive, polymeric, colloidal substances increased; 6, rapid changes in ambient temperature; 7, frequent changes or adjustments in working conditions; 8, a sudden power failure or failure Stop and so on. Three screw pump sudden leakage during normal operation, if not found in time, often lead to a larger accident or loss, we must pay attention to and take effective measures. Second, three screw pump leakage treatment 1, three screw pump inlet should be equipped with a filter, usually through the filter is not greater than the maximum particle 0.Imm. 2, check the unit and the connection part is fixed firmly; check suction pipe section and the meter connector connection is sealed. 3, check whether there is a certain gap between the coupling and strictly control the alignment of the two axes, the outer circumference of the coupling beating not exceed 0.05mm, the end face of the coupling beats should not exceed 0.Imme. 4, the first three screw pump before starting should be filled with working medium. 5, check the inlet pipe on the suction valve and the discharge valve on the discharge valve is fully open. 6, hand rotating three screw pump coupling, feel the screw rotation should be uniform, light, without any rotation or reluctantly stuck phenomenon. Three screw pump installation, commissioning of the quality of good or bad, directly affect the pump can operate normally and affect the pump life and performance parameters. It also has a vital impact on the vibration and noise of the unit. So pump installation, commissioning must be carefully carried out with the right tools.
