Failure mode and use the rubber ring is related to hypertension is usually a reason to make pressing the ○-ring failure, when found ○ type ring hardens into a rectangle or when you need to adjust the amount of compression, otherwise it will heat up. It is necessary to understand the use of a synthetic rubber temperature. Synthetic rubber ring big swell mostly 25LG3-10x5 multistage pump due to chemical erosion, and they have some of their own characteristics, such as high temperature resistant Viton mechanical seal, and ethylene, propylene ○-rings used in the oil and lubricants will swell, ozone NBR aggressive action, so do not install nitrile rubber in the motor, so the high temperature and chemical corrosion is usually caused by hardening of rubber products, the main reason for the crack. When installing rubber parts are surface nicks and cuts, but also a common cause of seal failure. The signs of the old fixed screw shaft, keyway, spline shaft 25LG3-10x6 mechanical seal, sharp shoulder so will damage rubber parts. Check that the hub or gland chamfer is appropriate, do not meet the requirements must be trimmed. Pipeline centrifugal pump bolts should be tightened evenly to prevent deflection gland section, check the points 25LG3-10x4 feed pump with a feeler or special tools, the error is not greater than 0.05 mm. Dynamic and static ring coated with a layer of clean oil or turbine oil. The gland should be carried out after the coupling alignment. Should be kept flexible and mobile ring after installation, after the ring is pressed against the spring should be able to automatically bounce back. Pipeline pump installation should seal gently to prevent damage to the seals, the installation should be sealed and cleaned cavity. To tighten centrifugal pipeline pump mechanical seal gland bolts fastening force should be uniform, to prevent damage to the mechanical seal uneven force. For fast-loading mechanical seals assembled in the overall positioning piece must not forget to move the road away from the axis of the radial position is fixed.
