What are the main reasons for oil leakage in mechanical electric rolling machines?
The occurrence of oil leakage during the processing of mechanical electric plate rolling machines not only affects the normal operation of the equipment, but also may lead to an increase in production costs and safety risks. This article will explore the main causes of oil leakage in mechanical electric plate rolling machines from the perspectives of thin hole covers that are prone to deformation, excessive oiling that leads to accumulation, lack of oil return groove design, improper maintenance techniques, improper casting treatment, unreasonable oil seal design, low or rough manufacturing accuracy, and improper exhaust cap configuration.
1、 The hole cover is too thin and prone to deformation
If the hole cover of the mechanical electric rolling machine is designed too thin, it is easy to deform, resulting in poor sealing and causing oil leakage. Therefore, in the process of equipment design and manufacturing, the thickness and strength of the hole cover should be fully considered to ensure that it has good sealing performance.
2、 Excessive refueling leads to accumulation
Excessive refueling is a common cause of oil leakage in mechanical electric rolling machines. Excessive lubricating oil can accumulate inside the equipment, increasing the risk of oil leakage. To avoid this situation, operators should follow the prescribed amount of oil when adding lubricating oil and ensure that the oil is evenly distributed inside the equipment.
3、 Lack of oil return tank design
The oil return tank is a key structure inside the mechanical electric rolling machine, used to recover excess lubricating oil into the oil tank. If the equipment lacks a return oil tank design or the return oil tank design is unreasonable, it will lead to the inability to recover lubricating oil smoothly, thereby increasing the risk of oil leakage. Therefore, in the process of equipment design and manufacturing, it is necessary to ensure that the design of the return oil tank is reasonable and effective.
4、 Improper maintenance techniques
Improper maintenance techniques are also an important reason for oil leakage in mechanical electric rolling machines. If operators do not follow the correct operating procedures during maintenance and upkeep of equipment, it may damage the sealing parts of the equipment or cause oil accumulation inside the equipment, leading to oil leakage faults. Therefore, improving the skill level and safety awareness of operators, strengthening training and management of maintenance techniques, are effective measures to prevent oil leakage in mechanical electric rolling machines.
5、 Improper handling of castings
During the manufacturing process of mechanical electric rolling machine castings, if not handled properly, there may be defects such as pores and sand holes, which can become channels for lubricating oil leakage. Therefore, in the manufacturing and processing of castings, quality should be strictly controlled to ensure that the surface of the castings is smooth and defect free.
6、 Unreasonable oil seal design
Oil seal is a key component of the sealing system of mechanical electric rolling machine. If the design is not reasonable, it will not be able to effectively prevent lubricating oil leakage. Unreasonable oil seal design may include improper material selection, inappropriate structural dimensions, etc. To avoid this situation, equipment manufacturers should optimize oil seal design, use high-quality sealing materials and reasonable structural dimensions to improve the sealing performance of the equipment.
7、 Low manufacturing accuracy or roughness
The manufacturing accuracy and surface roughness of mechanical electric rolling machines have a significant impact on the sealing performance of the equipment. If the manufacturing accuracy is low or the surface roughness is large, it may cause excessive clearance between the sealing element and the equipment contact surface, leading to oil leakage faults. Therefore, in the process of equipment manufacturing, manufacturing accuracy and surface roughness should be strictly controlled to ensure that the sealing performance of the equipment meets the requirements.
8、 Improper exhaust cap configuration
The exhaust cap is an important component inside the mechanical electric rolling machine, used to discharge air and impurities inside the equipment. If the exhaust cap is improperly configured or blocked, it can cause abnormal internal pressure in the equipment, thereby increasing the risk of oil leakage. Therefore, in the process of equipment design and manufacturing, exhaust caps should be reasonably configured and regularly inspected and cleaned to ensure their unobstructed flow.
In summary, the main reasons for oil leakage in mechanical electric plate rolling machines involve multiple aspects, including hole cover design, oil filling control, oil return groove design, maintenance technology, casting treatment, oil seal design, manufacturing accuracy, and exhaust cap configuration. In order to avoid and reduce the occurrence of oil leakage faults, targeted measures need to be taken to improve and optimize from these aspects. At the same time, strengthening the training and management of operators, improving their understanding and comprehension of equipment structure and maintenance techniques, is also an important way to prevent oil leakage in mechanical electric rolling machines.
