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.
The motor and saw blade in Reciprocating Saw is arranged in line. The saw is held by D-handle on the back and by its spindle neck or an auxiliary handle. High quality recip-saws come with internal counterbalance and active vibration damping and have a tool-free clamping system for the saw blade.
Power Tools are hand-held, transportable
electric tools in which motor is inseparable part of the machine.
Examples of conventional electrically power tools are screwdrivers,
drills, routers, sanders and a variety of saws, such as jigsaws,
reciprocating saws and circular saws. Compared to hand tools, Power
tools can help you to complete home repair and large-scale projects with
speed, ease and safety.
