How to maintain the lobe pump in normal times

lobe pump: For any mechanical equipment, the usual maintenance work done well, it is not only reflected in the production is normal, more importantly, directly affect the use of mechanical equipment orders, for the lobe pump, of course, is no exception, for this reason, pay attention to the following aspects of maintenance work. 1, seals, lobe pump seals are divided into static parts seal and dynamic parts seal The seal ring of the static parts seal (should be careful not to have scratches or bruises on the surface, otherwise, for a direct impact on the sealing effect; for moving parts seal, because it will be subject to pressure size and the corrosion of the transport medium, and the medium in the particles wear and many other factors (if a little careless, there is likely to be leakage phenomenon occurs. Once the product leaks, should promptly shut down and overhaul, wipe with a soft clean cotton cloth, coated with a layer of glycerin, assembled, first after hand, before the machine can be turned on and used, such as repair is hopeless, should be replaced with new parts. 2, lubrication parts, the pump's transmission gear, rolling bearings, must maintain good lubrication conditions, usually, often pay attention to the gear in the oil level, give enough lubricant, and to ensure that the oil quality is pure, clean 3, electrical systems, around the electrical equipment, not allowed to store the instruments, substances or gases that damage the insulation. At the same time must keep the electric equipment in a dry environment work. If it is difficult to avoid should be added with moisture-proof facilities. 4, daily maintenance, whenever the shutdown does not work, will be based on the nature of the materials conveyed, the choice of the appropriate cleaning agent, the pump will be effective cleaning, after also have to use clean water to clean again, to ensure that the pump clean and sanitary. lobe pump in the installation should pay attention to several issues: 1, the lobe pump and the motor out of the shaft connection, should first be their respective correction level and ensure that the two coaxial before installing the coupling, otherwise, will cause damage to the machine. 2, because the lobe pump is a fixed capacity pump, the displacement per revolution is fixed, once the previous process for some reason to stop working and the pump is still working, the pump The pressure will rise infinitely, leading to seal leakage, damage to the machine and other accidents, for this reason, we must take effective preventive measures. Example 1: The pump should be interlocked with the upper and lower processes, and the pump should be stopped at the same time when the upper and lower processes are stopped. Example 2: A safety valve and overpressure circuit system can be installed in the output pipeline, which will automatically unload when overpressure is applied. 3: If a control valve is added to the lobe pump, it can only be installed on the inlet pipeline of the pump, and a control valve should not be installed on the outlet pipeline, which will easily cause errors in overpressure. lobe pump after all the installation, should be a comprehensive check, including the mechanical parts of solid, electrical wiring, etc., and then, by hand, the pump will rotate 3 ~ 5 revolutions, listening to whether the phenomenon of stuck or loose, until normal, and then for electrical test run, such as the discovery of abnormalities, due to stop maintenance, service all normal before delivery to use.
