How to use and save the type A seal of flexible waterproof casing.

How to install the type seal of flexible waterproof casing A. The main installation method of the seal is manual installation. Therefore, although it is possible to squeeze the seal ring so that part of the seal ring enters the sealing groove of the tubing, it is difficult to adjust the position of the part of the seal ring that has not entered the sealing groove. The seal diameter is larger than the tube diameter, the nozzle diameter is small, and the finger size is too large. Therefore, manual installation of the seal is time-consuming and laborious. At the same time, long-term contact with the fingers and nozzles easily damage the fingers. The relative sliding surface roughness of the seal is usually more suitable to take Ra = 0.2μm, working conditions are not too strict, Ra value may be 0.4μm; sliding surface can not have processing defects. Pay attention to the installation direction of the seal ring, can not apply load pressure on the back of the seal ring.
 
When cleaning the waterproof casing inside the flexible waterproof casing, remove all protective plates from the casing and clean everything inside the entire pipe. Cutting and assembly of flexible waterproofing sleeves should be done according to the site construction drawings or the height of the building floor. The risers all use different hollow spiral pipes, and even the drainage branch pipes are solid wall pipes. A small scar on the lip of the seal during installation may lead to oil and gas leaks during installation.
 
Check the seal regularly to avoid wear and aging, which can lead to oil and air leakage, and replace it with a new one in time. When installing and replacing seals, use seals of the same specifications and standards in strict accordance with the requirements to ensure the sealing requirements. When installing, choose a special installation tool to avoid cutting your fingers by the sharp metal edge of the groove. Before installation, clean the groove, apply lubricant to the lips and do not knock hard. First press the seal into the groove, then gradually and evenly. During installation, insert the flexible waterproof sleeve into the waterproof sleeve according to the installation diagram of the drainage pipe and the upper and lower floor pipes, so that the connection of the whole pipe is very important.
