(1) sealing friction deputy face serious wear and tear. Due to the viscosity of residual oil, poor fluidity, and the residue medium contains granular and powdered cokes, there is inevitably coke around the friction pair, which is quite damaging to the friction pair. Once the coking material enters the sealing face, Po Taibang will quickly scratch the sealing face due to friction and vice-versa, causing scratches. As the polymer and foreign particles continuously enter the friction face, the sealing face will be gradually worn away and eventually seal Leakage failure. (2) Bellows assembly missing. ZYB-B-type high-pressure adjustable gear pump in the actual use of the process, in order to achieve sealing under high temperature and pressure conditions, contact bellows seal generally use a larger amount of compression, so that the sealing end pressure will be greatly increased , Friction side face serious wear and tear, while generating a lot of friction heat. If the frictional heat can not be taken away in time, the stiffness or elasticity of the bellows will gradually decrease or even disappear under the action of high temperature for a long time, that is, the missiles will bulge and the higher the temperature, the bigger the load, the faster the missiles will be. If the bellows missiles, seal the end face in the medium pressure immediately under the action, that is, a large number of leaks. (3) flushing oil, cooling water consumption. In order to prevent the sealing part of the temperature rise, resulting in coking, external flushing and cooling measures must be used to reduce the friction temperature rise, to prevent coking, thermal cracking, aging and lead to seal failure. To this end, it is inevitable to consume a large amount of flushing oil and cooling water, resulting in high operating costs.
