Spring hammer price, spring impactor model specifications

 Spring hammer price, a spring impactor model specifications, use spring shock is mainly used for household and similar electrical appliances shell, operating levers, handles, knobs, lights and other mechanical strength test. To ensure that the product is not damaged when subjected to unexpected and abnormal operation, to ensure safe and reliable operation. Second, the technical specifications 1 · body weight: 1250 g; 2 · the impact element Quality: 250 g; 3 · Cone Quality: 60 g; 4.1 Impact energy: 0.5J three, use Method 1. Place the test sample is required fixed, and then select the site in accordance with the requirements of the impact. 2. Pull the impact of the knobs until the release claw hammer handle stuck, so that the impact is in the cocked. 3. The vertical axis and the surface of the impactor test products, then slowly push impactor impingement appliance should have sufficient mechanical strength, and its structure should be subjected to rough handling live in normal use may occur. Compliance is checked by the use of a spring-driven impact tester IEC817 appliance applying the provisions of combat. Appliance is rigidly supported to live in every possible weak point of the appliance housing with impact energy 0.5J ± 0.04J hit three times. If desired, handles, levers, knobs and the like of the signal lamp and its parts and may be applied against a housing, or nacelle, but these lamps projecting housing to more than 10mm, or their surface area to more than 4 Cm2. Lamp and its shade within the appliance, and only when in normal use may be damaged, the test was carried out. After the test, the appliance should show no damage within the meaning of this standard, especially 8.1, 15.1 and 29.1 degree of compliance should not be undermined, in case of doubt, additional insulation or reinforced insulation to withstand the electric strength test of 16.3. If One drawback is hit before applying caused by doubt, then do not count this defect, then a new site should be subjected to the same test is applied to the sample as a group of three blows. Fourth, note impactor by school After the experience, do not disassemble and freely adjust the amount of compression springs, or affect the impact energy.
