Spring castor how to determine its quality and product spring castor products advantages: one, easily start. Castor spring mounted wheel is made of high quality polyurethane wheel core package, has the good elasticity and abrasion resistance, is put on the equipment use, motive force is small ( Such as 6 inch shock castor, in a single wheel load of 200 kg, motive force is 3. 6 kg) ; Second, the resistance to high speed. Castor wheels adopts double tapered roller bearing, in the process of high-speed traction can better prevent the wheels wobble, greatly reduces the noise, provide production workshop with a quiet environment for our production. Three, seal dustproof and anti-wind performance. Shock damping spring caster wheel seismic spring completely sealed, extremely good dustproof and anti-wind to suitable for different options and requirements. Four, shockproof performance. Choose good impact resistance seismic spring spring castor, using large diameter bead plate orbit, and base plate, upper plate after heat treatment, can greatly improve the hardness and toughness of bead plate, make bead plate rotating more flexible, easily greatly improve mechanical performance, avoid the wheels on the concave and convex surface damaged by vibration. Spring castor how to determine its quality 1, reciprocating wear testing: castor reciprocating wear test to simulate the casters in daily use the actual rolling, the two points with and without obstacles obstacles test test, in the process of test are not allowed to have a castor or other parts from, 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. 2, rolling resistance and rotational resistance measurement: when castor mobile or to control the driving direction, the power must be on the object to the caster and to overcome certain resistance, resistance depends on the size of the: weight, wheel diameter, material, round face shape, castor rotating field. 3, resistance performance test: test the performance of 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, on the caster wheel load of 5% to 10% of the nominal load. With the insulation resistance tester ( Nominal open circuit voltage of 500 v, determination of the resistance value of fluctuation within 10% and no more than 3 w) in the wastage of the products The electric resistance between castor and metal plate. In type conductive castor, resistance is not more than 104, and the resistance of the antistatic caster should be between 105 and 107. 4, impact test: any goods transportation, use, preservation and other situation will impact vibration may be produced and make the product a certain period of time can't normal use, the furniture with its type, weight and other characteristics are often vulnerable to the impact, and smooth at the bottom to determine whether furniture placed casters are more should have a good shock resistance. 5, static load test: castor should always be steady running on the ground, but it is almost a state of pure theory. On the uneven surface, or in a threshold, orbit and potholes, castor will brief off the ground. So when they suddenly overloaded or four casters in three only contact with the ground, must carry the entire load of furniture.
