Magnetic oil drain plug manufacturers introduce the common problems of high-strength magnetic oil drain plugs in detail
With the development and progress, the industry's demand for high-strength magnetic oil drain plugs is getting higher and higher, and the demand for high-strength magnetic oil drain plugs is also increasing. High-strength magnetic oil drain plugs can meet everyone's pursuit. At this stage, the development of high-strength magnetic oil drain plugs is promising, but there are still some problems with high-strength magnetic oil drain plugs in China. According to the manufacturer of the magnetic oil drain plug, the following problems exist.
1. The guaranteed load and the wedge load do not meet the requirements. Ensuring the load and the wedge load is an important item to evaluate the mechanical properties of the product under tensile load. Especially important for high strength magnetic drain plugs. The assurance load is used to assess the plastic deformation resistance of a product under a specified tensile load. If the index value does not meet the specification, due to the effect of preload and working load, it is likely that plastic deformation will occur, thereby reducing the preload and loosening the connection.
The wedge load test is the identification of the compressive strength of the bolt product and the strength of the head-to-rod connection. This database index is not compliant. Under the effect of large load, especially under the effect of impact load, or when the support point surface is subjected to partial load effect, it will break or turn around, resulting in invalid connection and even safety production accidents.
2. The strength is not enough. Strength is also the main index value for evaluating the mechanical properties of high-strength magnetic oil drain plugs. The raw materials used for each performance level product are not the same. When selecting high-strength magnetic drain plugs, the mechanical property level is an important criterion. During assembly and application, the working load and installation torque should be specified according to the performance level. For special raw materials, the strength should be adjusted to an effective degree, and the high toughness can reduce the fatigue-relieving performance of the product. In order to improve the compressive strength of products, some companies control the strength at a higher quality, resulting in some products exceeding the standard.
