The definition of the spring
The spring is an elastic mechanical part to work. To control the movement of parts, ease the shock or vibration, lay aside energy, measuring the size of the force, are widely used in machinery, instruments. Complex and diverse types of springs, coil spring, spiral spring, flat spring shape points.
Basic knowledge about spring
The plate spring is classified according to shape: First, oval plate spring Second, the semi-oval shaped plate spring Third, quarter oval plate spring Fourth, piece spring The plate spring of the oval-shaped plate spring, a semi-oval shaped plate spring, and a fourth elliptical-shaped plate spring are combined type, relying on the frictional force between the board and the board has a high cushioning and vibration damping properties, widely used in cars, tractors and railway vehicle suspension system; leaf springs for monolithic spring steel, used for compressing the working parts of machinery and equipment and instrumentation. 
Professional suggestions about high-quality spring Because at the time of installation, too light much of a load-bearing floor spring door, such as selection of not only increasing the cost of door ideal door effect also cannot be too heavy. Project cost savings and selection of the loading capacity of the floor spring, will also directly affect the life of the mould spring, early replacement of spring. Outdoor doors, taking into account the external wind factor, regardless of door leaf size should be chosen double cylinder floor spring, due to the 0 ° positioning of the two-cylinder floor spring and 90 ° positioning is relatively better than single spring. Cold regions ground spring antifreeze oil pressure should be used to prevent the normal operation of the temperature are too low to make the spring.
Good quality spring criteria:
(1) Life: National Institute of Standards First grade = 30 million times open, quality product = 50 million times to open European standard is a minimum of 500,000 times, so says the chosen ground spring would reach 500,000. (2)Ground cover of the spring: 304 stainless steel models must be chosen. The cover must be firm, and selected a little thick, 2mm basic is the most high-end. (3) Price: the gap between service lives with high-grade low-grade spring the spring will be great. So spring price volatility, in stores or manufacturers, the high-end price of the spring will be relatively high.
