[Three rain valve to recommend Star Products - Mechanical seal] Description: After the plane of the plate and the surface roughness of the calibration standards, require its pressure sand, pressure sand mixture commonly used chemical formula is: chrome corundum grinding powder 20g, stearic acid 0.5g, aviation gasoline 200mL, kerosene 10mL. After the mixture is configured M74D-60 mechanical seals, to be placed more than a week then. Pressure sand process is as follows: (1) the plate with industrial gasoline to clean M74D-45 mechanical seals, then wipe aviation gasoline. (2) the mixture was shaken, left to stand for a moment, with a small dropper after inhalation of droplets on the plate M74D-90 mechanical seal and uniformly spread in a thin layer. (3) Put the plate was polished until the adhesive force between the plate bigger, pressure sand agent is in glossy black, viscous state to, to move forward when the pressing need to hand on the plate while the plate 90 is rotated from time to time °, 180 ° to increase the suction force. (4) pressure sand removed after two plates, sprinkle with a clean dropper aviation gasoline, residual layer with cotton wool wipe, and then one piece with the end plate further pressure sand sand pressure. [Three rain valve to recommend Star Products - Mechanical seal] Description: Sealing principle structure PM SUER ETX270 type grinder mechanical sealing structure shown in Figure 1, the shaft with double mechanical seal, the right atmospheric side seal, left for the media end seal. Wherein the sleeve shaft 1 and the grinding clearance fit and run simultaneously by 3 seal oil seal rotating sleeve 1 and 2 sealed chamber. Atmospheric side seal 5 is pressed against the stationary ring 6, atmospheric side seal stationary ring 6 and the seal chamber 2. Anti-rotation pin 4 to prevent air terminal 6 and stationary ring seal chamber 2 relative rotation. The top end of the spring wire 10 atmospheric seat 26 is fixed to the hub a mechanical seal, its left end face has 12 air end of the spring 28 pushes the atmosphere end ring 9, the atmosphere end ring 7 right-side surface and atmospheric static ring 6 left face contact, by the ends surface contact friction, rotating sealing. Both end faces worn by the spring force can be automatically compensated. M74D-55 mechanical seals, mechanical seal, rain, Fuyang mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin.
