Ground spring installation steps

A. Draw the line so that the center of the ground spring shaft coincides with the door clamp shaft.

B. According to the instructions and the actual object, the hole should be tightly fixed to the floor spring case and should not be loose.

C. Place the ground spring in the opened hole and square it.

D. Lift the door leaf with the door clamp so that the shaft of the floor spring is inserted into the shaft hole of the door leaf.

E. Adjust the screws in the three directions of the ground spring. Keep the door leaf vertical and the top and bottom rotation axes coincide.

F. Adjust the speed of closing the door.

G. Cover the ground spring cover

The installation accuracy of the floor spring has a great influence on its service life. The quality defects of floor springs mainly include: body oil leakage and earth axis eccentricity. The oil leakage of the body is caused by the casting process of the ground spring. If the liquid pressure inside the body is increased after the installation of the sand eye in the casting process, the oil leakage phenomenon is caused. The eccentricity of the ground shaft can cause the door body to deviate from the center line of the door after installation. Although some quality defects can be compensated for by the position adjustment of the body, it is best to contact the manufacturer for replacement. The end of the service life of the ground spring is that the shaft oil leakage and the elastic force are weakened. If the connection between the sun shaft and the shaft center of the ground spring shaft is not strictly perpendicular to the ground, the movement of the door leaf will bring great torque to the floor spring and increase the main shaft. Wear between the bearing and the bearing eventually leads to oil leakage in the shaft. The spring will inevitably weaken the elasticity after long-term stretching.
