How to choose the casters on the air-conditioner

How to choose the casters on the air-conditioner of air-conditioner castor is move one of the most important parts of air-conditioner, freezer castor quality directly affect the move freezers effect in the practice and experience, so the choose and buy of air-conditioner castor should note what respect? The wheel material: this is very important, ordinary PU, TPR, PP, rubber, nylon, etc. , as for the suitable temperature, surface hardness, air environment, etc. Choose size: ordinary freezers caster wheel diameter, the greater the push, the more energy saving insurmountable obstacle to the better, because of air-conditioner castor industrialization of the first of the west in the late 19th century, so the size of the air-conditioner castor ordinary in inches, such as China's supermarket trolley mostly with 5 inch, 4 inch of air-conditioner castor. Popular on the market at present of air-conditioner castor size from 1 to 10 inches, the size of the commonly used 2 inch, 2. 5 inch and 3 inch, 3. 5 inch and 4 inch, 5 inch, 6 ', 8 ', 10 ', such as ordinary often needs to promote, such as supermarket shopping cart, logistics trolley, factory using 4 ~ 6 inches of air-conditioner castor is preferred. But too much freezers caster wheel diameter can make equipment center of gravity rises, capital increase, so let's stop comprehensive thinking. If the device does not demand often propulsion, such as furniture, refrigerator, etc. , only needs to move during cleaning, choose 3 inches below the air-conditioner castor. See bearing: the same diameter freezers castor, ordinary manufacturers are spending several series for different bearing, such as light, medium, medium, and so on, way is to make the wheels and stents have different thickness or material. Calculate the load of a single freezers castor to offer certain insurance coefficient, compare with flat on air, a single freezer caster wheel load = ( Equipment had been present on the number of air-conditioner castor) ×1. 2 ( Insurance coefficient) ; As if the air is not smooth, the algorithm, the total weight of single freezers caster wheel load = equipment present 3, due to either uneven air, always at least three wheels support equipment at the same time, this algorithm is equal to increase the coefficient of insurance, more secure, to avoid the lack of bearing, air-conditioner castor life greatly reduce or cause accidents. In foreign company, bearing ordinary expressed in pounds, and most domestic use kg and their conversion relations are: 2. 2 pounds = 1 kg. Brake: in terms of function, brake wheel, brake bracket wanxiang, both with brake is double brake, and tread brake, brake, brake, etc, the contact of air-conditioner castor plant in detail. ( Step fly castor] Device: light load can be used in ordinary screw, insert rod, plastic shrinkage sleeve, overloaded with floor, or directly welded to the device. Normal mode of large company unit is very rich. Freezers casters on the equipment arrangement: arrangement is different, not only influence capital, promote the feel also greatly different.
