The impact resistance of polyurethane casters originally so powerful

Pu castor impact resistant ability was so strong, spring damping castor is mainly used in automobile manufacturing industry, generally require castor has good turning performance, suitable for high-speed drawing. Resistance to high speed around the island shockproof 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. 2. Anti-shock performance quality selection of impact resistance aseismic springs, 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. 3. Start around the island shockproof foot wheel is made of high quality of new type high elastic polyurethane wheel core package, has the good elasticity and abrasion resistance, is put on the device, when using the dynamic small ( Such as 6 inch shockproof wheel, in a single wheel load of 200 kg, motive force is 3. 6 kg) , seal dustproof and anti-wind performance circle new shockproof castor seismic spring completely sealed, extremely good dustproof and anti-wind to suitable for different options and requirements. Pu castor impact resistant ability originally so strong pu castor 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. 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. If the two plans are to feel, small make up to you the most sincere eyes. It is conceivable that the customer is a person with the request. Pu castor derusting. If use hand hammer, shovel, knives, steel wire brush, coarse cloth ( Paper) Outside, with corrosion of the metal stop disposal, a way and get to the rust removal request. Electric tools derusting. Also called half derusting machine, main if adopt the wind ( Electricity) Brush wheel or type cleaning machine, with the outside of the rust stop disposal, and reach the castor derusting request a way. Radiation or mass ejection derusting ( Also known as sandblasting derusting) 。 With the aid of oil-free compressed air (important Or low pressure water) Manual cleaning of chemical cleaning is much trouble, and manual derusting outside very easily damaged layout, at the same time anomaly is a waste of time and manpower, sages don't generally universal caster wheel parts manual derusting, except to the outside without any request and small area of the rust stains can adopt this way. Pu castor 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. In the process of pu castor reality application, often in the face of many problems; And environment is the most rare environment such as rendering rust, so much is very easily affect castor all the beauty of the look and feel, and once the trundle presents the rusty environment, along with the time of the forging and sophisticated applications, castor will not easily applied. With the aid of chemical cleaning: rust remover derusting. The Lord if use one kind of weak acid chemical liquid ( The rust remover) Brush or immerse rusty metal outside, through the chemical reaction process will remove the rust on the metal outside a way. Chemical cleaning ( Also known as pickling) 。 Important to adopt organic brush dilute acid solution ( Spray) , soaking with rust metal outside, and a way to reach the purpose of rust removal. With the help of chemical cleaning, castor parts derusting solution is abnormal convenient, important is through the process of reaction between outside to remove rust stains, now the cities, there are many chemical herbicides, deploying the double convenient for application. Pu castor rolling resistance and rotation 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, caster wheel rotation of field. 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.
