356×254 Spin Sealed Brake Cylinder After Active Lubrication Modification Research and Suggestion on Mitigating Bad Problems
In order to solve the problem of poor brake cylinder relief that exists after the modification of 356 × 254 spin-seal brake cylinder active lubrication,factors such as friction in the waterproof part of the front cover of the brake cylinder,friction in the sealing part of the piston,and spring force of the relief spring were studied and verified,and the correlation between the initial action of the piston in the brake cylinder pressure during the brake cylinder test bench sensitivity test and the spring force of the relief spring was calculated.The results show that the problem of poor relief of this type of brake cylinder is not a problem caused by a single accessory or factor,and that it is necessary to control the parameters of each type of accessory and its co-ordination during the process of modification and overhaul,and to put forward a proposal to increase the relief spring relief force.
