How to stimulate higher performance of second-hand generator recycling in Dongguan
To make full use of the generator's performance, the usual maintenance is very important. What the Dongguan second-hand generator recyclers want to popularize today is the importance of grease for generators! During use, all generator grease will deteriorate due to oxidation, excessive oil leakage, mechanical operation and oil volatilization.
In actual operation, to maintain and even excite the performance of the motor, it is very important to formulate and follow a scientific motor bearing lubrication management plan.
Here are ways to excite the higher performance of the generator:
I. Timing
The factors that affect the frequency of grease replacement are very complicated, and generally include temperature, continuity of use, grease injection volume, bearing size and speed, seal effectiveness, and the suitability of grease for special applications. Therefore, deciding when and how often to change grease is not an easy task.
Under normal circumstances, continuous operation of light-to-medium-load motors requires that grease be replaced at least once a year; every 10 ° C above the nominal recommended temperature, the grease replacement interval needs to be reduced by half.
Second, quantitative
Determining the amount of grease injected into a motor bearing is one of the important steps when the bearing is first lubricated and when the grease is replaced. Insufficient grease injection will cause insufficient lubrication and cause bearing failure, while excessive injection quantity will cause bearing failure and cause problems caused by grease being brought into the electromagnetic winding. You can refer to the following two methods to determine the amount of grease injected into the bearing:
1/2 to 2/3 of the remaining space in the bearing-when the running speed is less than 50% of the bearing's ultimate speed
Another method to determine the proper amount of grease for the bearing is to use the following formula:
o Grease injection amount (g) = bearing outer diameter (mm) X bearing width (mm) X0.005;
o Or grease injection amount (ounce) = 0.114X bearing outer diameter (inch) X bearing width (inch) X0.005;
Ordering
Dongguan used generator recovery personnel to remove as much old grease as possible is an important method to prevent grease deterioration, leakage and contamination, and also the key to avoid incompatible grease mixing. Therefore, after confirming the replacement time and replacement amount, you must follow a rigorous rinsing and fat changing procedure! Taking a rolling bearing equipped with a grease port and a grease drain port as an example, the 5-step "decompression method" can be used to clean and flush cleanly.
1. Disassembly: Remove the grease drain bolt located below, and remove all hardened grease from the grease drain;
2. Wipe: Wipe the grease opening;
3. Note: Inject the grease into the grease port until the new grease is drained from the grease outlet, ensuring that all the old grease has been drained. In the case of ensuring that the equipment operating environment is safe and feasible, this step can be performed while the equipment is running;
4. Discharge: No need to install grease drain bolts, the motor runs normally and maintains the operating temperature, the grease will be extended to distribute evenly, until excess grease is discharged from the grease drain, thereby reducing internal pressure;
5. Installation: Remove excess grease and install grease drain bolts.
Choosing the right grease is the basis for the renewal of the entire motor bearing. With the increasingly severe lubrication environment of generator equipment, it is very important for used generator recyclers to choose a high-performance grease. Grease is a semi-solid lubricant consisting of a base oil, a thickener and additives. High-quality motor greases are based on typical indicators such as viscosity, consistency, oxidation resistance, anti-wear, drip point, and shear stability Both performed well. http://kongtiaoweixiu0.cn/
