Regularly check the wear condition of pu castor and make the corresponding processing

Pour pu castor vertical to install on the surface of the test platform, make quality for 5 kg of noon from height is 200 mm, allow 3 mm deviation for the position of the free fall impact caster wheel, if for the two rounds of the two wheel should be hit at the same time. Static load test pu castor static load test impact test simulates the pu castor castor reciprocating wear in their daily use of the actual rolling conditions. Regularly check the abrasion of pu castor with an obstacle and make the corresponding processing the points test and no obstacle test two kinds, the trundle put to the test platform is installed correctly, each test castor load of 300 n, test frequency is ( 6 - 8) Times/min, a test cycle including 1 m and 1 m back to reverse a back and forth movement. In the test process are not allowed to have castor or other part out, at the end of the test each castor should be able to drive its normal function, test after the completion of the caster roll, circuition or brake function should not be damaged. Pu castor check method of impact resistance testing loose pu castor wheels or jammed also can cause & other; Grinding flat spot & throughout; , the appropriate maintenance check, especially check bolt tightness, lubricating oil, to replace the damaged rolling performance and rotary motion of the pu castor can enhance flexibility. Castor static load test process is to casters in horizontal smooth steel with screws testing platform. Along the pu castor 800 n the center of gravity of the direction of the force for 24 h, will force excluding 24 h after the check of the condition of the castor, after the experiment measured the deformation of castor does not exceed 3% of the wheel diameter, and caster roll experiment is completed, circuition or brake function has no damage is qualified. Reducing wear is to maintain an aspect of the industrial castor wheels, on the other hand we also starting from the ground, some reason occasions ground condition was very bad, after the industrial castor wheels must remember to check the wear situation, make corresponding processing. High elastic polyurethane casters manufacturers reciprocating wear testing when testing the performance castor should keep dry and clean, place the caster in a piece of insulation on the metal plate with the ground, keep the wheel edge in contact with the metal plate, the polyurethane casters to load the standard load of 5% to 10%. By measuring insulation resistance tester castor and resistance value between the metal plate. Pu castor or slack is likely to lead to serious breakage scroll is not stable, leakage, load is unusual, and floor damage and so on, timely replacement of damaged can reduce downtime due to damage of castor castor and bearing the cost.
