Constant force spring support hanger

Product introduction:

The constant force spring support hanger (hereinafter referred to as the constant crane) is designed according to the torque balance principle. The load torque and spring torque are always balanced under the allowable load displacement. For the pipe and equipment supported by the constant crane, a constant supporting force can be provided when displacement occurs, thus no additional stress will be brought to the pipe and equipment.

The constant crane is generally used to reduce the displacement stress, such as power station boiler body, power plant steam, water, smoke, wind pipe and burners and other suspended parts, as well as petroleum and chemical industries need such support.

When the thermal displacement of a lifting point in the pipeline system is greater than 12mm, it is appropriate to choose the constant lifting to support, so as to avoid dangerous bending stress and adverse stress transfer in the pipeline system.

I. Main Technical Features:

Rated load: 0.2 ~ 400kN Displacement: 0 ~ 508mm

Allowable field load regulation :±10%

Ii. Main Technical parameters:

Specified load deviation (including friction) within the full stroke :≤6% Average load and design load deviation within the full stroke :≤2%

When locked, it can bear 2 times of the maximum working load.

Iii. Structure composition and Working Principle:

The company mainly engaged in the production of spring type constant force hanger, can also provide the main and auxiliary spring type or other forms of constant force hanger according to the user's requirements. The spring type constant force support hanger is designed according to the torque balance principle. It relies on delicate geometric design, so that the load moment and spring moment in the working process is always balanced, in order to maintain a constant supporting force, can eliminate or reduce the additional stress on the pipeline or equipment.

The main and auxiliary spring constant force hanger is designed according to the principle that the resultant force is constant under the joint action of the main spring force and the auxiliary spring force.

The spring type constant force support hanger is mainly composed of cylindrical spiral spring and lever mechanism. Because its spring and component manufacturing technology is simple, mature, product performance is stable, good economy, in the domestic long-term application, so it is the most widely used type; The performance of the constant force hanger with butterfly spring is relatively difficult to control, while the constant force hanger with main and auxiliary spring requires high precision of spring, so it is difficult to manufacture and has not been widely used.

The company introduced from ITT steam-water Grinnell design, manufacturing technology, the localization of 58 series steam-water constant force, has a variety of forms, use convenient, good performance characteristics, deeply welcomed by customers at home and abroad.
