Whee flangel and track lubrication system

The whee flange and track lubrication system are among the most cost-effective oil-air lubrication systems. The system is small and simple, with low purchase costs, but the returns after adoption are tens or even hundreds of times greater than the investment cost.

Details

Installing a rim oil and air lubrication system on a locomotive has the following benefits：

01 Greatly reduces the risk of the wheels detaching from the track.

02 Reduces noise, especially in corners and tunnels.

03 The fuel consumption is very small, and the average fuel consumption of a locomotive traveling 1,000 kilometers is only 500ml.

04 There is no environmental pollution. Due to the fine coverage of lubricants, no dirty oil was found along the railway.

05 The wear of the rim of the wheel is greatly reduced, and the number of times and maintenance costs of the wheel are ground due to the wear of the rim are reduced.

06 The amount of maintenance is small, and the rim lubrication device has as few moving parts as possible, so there is almost no need for maintenance, just regular refueling.

There are the following control methods for rim lubrication：

Distance control

The system works at a set distance.A tachometer is used to measure the driving distance. Once the locomotive has traveled a certain distance, the “lubrication contact” on the tachometer sends a signal to put the rim lubrication system into work.

Time control

The locomotive travels slower in corners than on straights, so the time control method can ensure that the time interval between every two lubrication in corners is shorter than on straights, that is to say, based on the time control method, the rims get more lubrication on corners than on straights.

Curve control

The rim lubrication system provides a new solution. The curve sensor is installed on the front of the car, while the other parts of the lubrication system are assembled on the bogie that enters the curve with the front of the car, thus ensuring that the lubricated rim is in contact with the track head at the curve and the lubricant is transmitted to the rear rim and the rim of the next locomotive.Of course, in some cases, the curve sensor can also be assembled with the electronic control device of the rim lubrication system.

Hybrid control

Practice has proved that the time control method is a simple and reliable control method.Therefore, time control is often used as the basis of hybrid control, while curve control is used as an auxiliary control method.On straights, the time control method can realize that some lubricant is sprayed every once in a while to lubricate the rim, so there will always be some lubricating oil film on the rim, as well as when entering the curve; during the curve, changes in centrifugal force can cause the system to increase the number of injections and the amount of lubrication.At the end of the curve-when leaving the curve, the bogie of the locomotive will return to the center position. At this time, the rim and the track head will come into contact on the inside of the curve, so the inner rim needs to be lubricated at this time; on the contrary, the outer rim needs to be lubricated when entering the curve.In short, the hybrid control method can effectively provide lubrication for the left and right rims.
