Customized constant support hanger for boiler body of the power station, steam, water, smoke, air ducts

Product description

Constant force spring support hanger (hereinafter referred to as constant suspension) is designed according to the principle of moment balance.With the permissible load displacement, the load torque and the spring torque are always balanced.For pipes and equipment supported by constant hanging, when the displacement occurs, it can provide a constant supporting force, so it will not bring additional stress to the pipeline equipment.Permanent cranes are generally used in places that need to reduce displacement stress, such as the boiler body of the power station, the suspended parts of steam, water, smoke, air ducts and burners in the power plant, and places that require such support in the petroleum and chemical industries.When the thermal displacement of a hanging point in the pipeline system is greater than 12mm, a permanent crane should be selected to support it to avoid dangerous bending stress and unfavorable stress transfer in the pipeline system.The spring-type constant force support hanger is designed according to the principle of moment balance.It relies on a sophisticated geometric design to make the load torque and spring torque always balanced during the work process to maintain a constant supporting force, which can eliminate or reduce the additional stress on the pipeline or equipment.The main and auxiliary spring-type constant force support hangers are designed according to the principle that the combined force is constant under the combined action of the main spring force and the auxiliary spring force.Constant force spring support hanger is mainly composed of cylindrical coil spring, fixed frame, slewing frame and motion mechanism, adjusting device, spring cover tube and so on.

Application

Constant hangers are used for piping and related components where higher levels of vertical travel occur. Their job is to transfer the working load over the whole travel area while keeping it constant, i.e. without any considerable deviations. The functional precision of the constant hangers is decisive for favourable long term behaviour of the components involved.

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.

Specification

1. Main technical features: rated load: 0.2 ~ 400kN displacement: 0 ~ 508mm

2. Main technical parameters: specified load dispersion within full travel (including friction) :≤6% deviation between the average load within full travel and design load :≤2% when locked, it can bear 2 times the working load.

Structure composition and working principle: 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, the product performance is stable, the economy is good, has been used for a long time in the domestic, therefore is the current widely used type;The performance of constant force hanger with butterfly spring is relatively difficult to control, while the main and auxiliary spring constant force hanger requires high precision of spring, so it is difficult to manufacture, so it has not been widely used
