Use a thread insert kit to replace a stripped thread or add a threaded insert into sheet metal, fiberglass or other brittle material. Choose from kits with standard inserts or helical inserts (also known as helicoil inserts). Thread repair kits include everything you need to repair or install threaded inserts, including a hand drill and installation tool to speed maintenance and reduce downtime.

Slurry pump mechanical seal: preparation before use can not be ignored
In the slurry pump accessories, mechanical seal is undoubtedly very important. Mechanical seal is not good, it will cause some leaked condition. Therefore, the quality of the mechanical seal directly affects the efficiency of the slurry pump. Therefore, before using the slurry pump, be sure to check the mechanical seal. Slurry pump machine prior to use the mechanical seal inspection items are as follows: ①slurry pump start, the need to check the mechanical seal attachment, cooling lubrication system is perfect smooth. ② Before starting the material line should be cleaned to prevent rust impurities into the sealed chamber. ③ Hand pallet coupling, check the shaft is easy to rotate, if the pan is heavy, you need to check the installation dimensions are correct. ④ Before driving normally, static pressure test is required to check the sealing effect of the face of the mechanical seal, the sealing ring and the sealing cover. If there is a problem, check and solve the problems one by one. ⑤ slurry pump start, the sealed chamber should be kept filled with liquid or sealed medium, if a separate sealing system should be started, the cooling water system also has to start circulating. ⑥ normal use, the first atmospheric pressure operation, observe the sealed parts of the temperature rise is normal, whether the phenomenon of leakage. If there is a slight leakage, you can run together for some time, so that the face fit more evenly, until the leakage gradually reduced to normal so far. Such as running 1-3 hours, the amount of leakage is still not reduced, you need to stop inspection. ⑦ normal working conditions, step-up heating can be slow, respectively, and pay attention to the temperature rise and leakage of the face, such as all normal, that can be put into production use. Slurry pump mechanical seal is so important, so be sure to do a good job before using the inspection.
