Product Description
Vertical Constant Force Spring Hanger Pipe Support ISO 9001 Certification Guarantee
Mental Constant force spring hanger ISO 9001 Certification Guarantee
Product description
Constant force spring hanger (hereinafter referred to as the constant crane) is designed according to the principle of torque balance.The load torque and spring torque are always in balance with the allowable load displacement.For the pipe and equipment supported by constant crane, a constant supporting force can be provided when displacement occurs, so additional stress will not be brought to the pipe equipment.The constant crane is generally used to reduce the displacement stress, such as the boiler body of the power plant, the steam, water, smoke, wind pipe and burner of the power plant, and the oil, chemical industry needs such support.When the thermal displacement of a lifting point in the pipeline system is greater than 12mm, it is appropriate to choose a constant crane to support, in order to avoid dangerous bending stress and adverse stress transfer in the pipeline system.
Technical parameters
Specified load deviation (including friction) within full travel :≤6% average load deviation within full travel and design load deviation :≤2%
When locked, can withstand 2 times the working load.
The working principle
The spring constant force support hanger is designed according to the principle of torque balance.It relies on the delicate geometric design, so that load torque and spring torque in the work process always balance, to maintain a constant supporting force, can eliminate or reduce the additional stress on the pipeline or equipment.
Main and auxiliary spring type constant force support hanger is designed according to the principle that the resultant force is constant under the action of the main spring force and the auxiliary spring force.
In general, in the important parts with large thermal displacement, it should be considered to set up the constant force spring hanger, because of this characteristic of the hang hanger, so in ordinary thermal power plants, nuclear power plants, petroleum and chemical and other thermal power plant has been more and more widely used.
