मुख्यपदानिः

1. स्थितिं विस्थापनम्
Each of the two 105m2 sintering machines in the Chongqing Iron and Steel Sintering Plant has over 90 lubrication points. The head and tail of the machines are lubricated with manual dual line centralized lubrication, while the slide is lubricated with an electric dual line centralized lubrication system. The lubrication points are powered by manual and electric dry oil pumps, and are supplied with oil through a dual line distributor. Due le limitations of the principle and structure of the dual line centralized lubrication system, the following problems often occur during use:
1. But lubrication points that are close to the pump, have low back pressure, and low resistance are the first to receive oil supply. If one or several of them are blocked, it is not easy to detect. şd
1.2 क्या वितरकवितरकवितरकविधीयन्तेलं कश्चिदपि निर्धारितुं परीक्षणे वितरकवितरकविधीन कार्याचित्रम्। şd
grease, given to the lubrication point is affected by factors such as pipeline distance, back pressure, and resistance. If the amount of grease does not match the predetermined amount, it is easy to have too much or too little or even interruption şd
1.4 Fault points are difficult to detect (such as high resistance in the distributor and blocked lubrication points), which can easily cause equipment damage due to oil loss at the lubrication points. şd
1.5 Manual pump refueling is difficult, increasing the labour intensity of workers. Because of its poor reliability, it is not suitable for modern production needs. şd

3. Design of lubrication system for sintering machine
3.1 The lubrication of the slide of the sintering machine not only requires high requirements in the selection of the oil supply pump, circulation mode, and automation level, but also plays an extremely important role in the selection of lubricants and the design of lubrication systems. Otherwise, an oil film cannot be formed between the trolley sealing plate and the bellows sliding plate, which not only fails to provide lubrication, but also damages the seal, causing the sliding plate to wear out and leak air. şd
