First, the definition of mechanical seals and hydraulic seals: Mechanical seals are precision, one of the more complicated mechanical structure foundation element ISW200-250I mechanical seals, a variety of pumps, reaction synthesis reactor, turbine compressors, submersible motors and other key components. Sealing performance and service life of the mechanical seal depends on many factors, such as the accuracy of selection, the machine, the correct installation and so on. Hydraulic seal pressure demands to have some combination of surface roughness, more rubber sealing element, to achieve the effect by local deformation of the closure seal. Second, mechanical seals and hydraulic seals mechanical seal type classification: cartridge seal series, light mechanical seal series, heavy machinery, such as hydraulic seals seal series: lip seals, V-ring, U-shaped ring, Y-ring, YX-ring hydraulic cylinder seals commonly used combinations and mostly bud rings, cell to circle and Lancaster closure. 5, for the pump when installing the mechanical seal the cavity in the open ends of the contact must be made by sealant to prevent leakage of the liquid from the gland. 6, in order to reduce friction on the shaft or sleeve seal contact area can be evenly coated with oil or grease or clean water or soapy water, but should be noted ISW200-200IA air conditioning pumps, elected with ethylene-propylene rubber "O" ring When ISW200-250 mechanical seal, not in contact with mineral oils and fats, water or silicone oil cleaning and lubrication. Stationary ring "O" ring lubricated with water, applying external pressure to install a stationary ring. 7, when the small spring mechanical seals, check the small springs are the same length and rigidity. The spring rotation to the relevant mechanical seal (ie fixed rotation mechanical seal), from the stationary ring to the rotating ring watch with rotating shaft, clockwise rotation of the shaft need to right-handed spring, and vice versa for left-handed. Air conditioning pump mechanical seal _ISW200-200IA _ circulating pump (certified merchants) provided by Anguo City Stone yuan Pump Company. Shi Yuan Yasukuni City Pump Co., Ltd.
