BAIJIAN - Third party testing organization
1. Valve springs often encounter failure problems due to long-term compression、 which causes plastic deformation and affects the shortening of free length、 weakened elasticity、 and skewed spring body. If strictly prohibited、 spring breakage may occur; 2. The key to detecting valve springs is to observe whether there are cracks or breaks、 measure the free length and verticality of the spring、 and measure the spring force. Valve springs cannot be repaired and can only be replaced if necessary; 3. The free length of the valve spring can be measured using a caliper. For the detection of the verticality of the valve spring、 the verticality of most valve springs should not exceed 1.5-2.0mm. If the free length or verticality of the valve spring does not meet the standards、 the valve spring should be replaced; 4. The elasticity of the valve spring should be tested on a dedicated spring tester. The tester should be used to apply pressure to the valve spring. The height of the valve spring under the limited pressure or the pressure under the limited valve spring height should meet the standard、 otherwise the valve spring should be replaced
