Hengli Clockwork SpringThe support hanger (collectively referred to as the constant hanger) is designed according to the basic concept of moment balance. Under the allowable load deviation, its load torque and deflection torque are maintained for a long time. It can be used for industrial production of pipelines and mechanical equipment with thermal deviation, and can achieve stable bearing capacity, thus not easily causing additional stress fields to pipelines and mechanical equipment.clockwork springLubricating grease is generally used in important areas with significant thermal displacement, and constant force spring supports and hangers should be fully considered. Due to the characteristic of constant force spring supports and hangers, spring series connection is becoming increasingly widely used in the thermal power system software of general heating and power plants.

A newly built power station is equipped with a supercritical extraction 350MW generator unit, and there are a total of 26 seismic supports in the hot section pipeline of the electric water heater, including 19 Hengli seismic supports; There are 13 seismic supports for the main steam pipeline and 9 seismic supports for Hengli. After the completion of the blowing of the heating furnace boiler pipes in the heat treatment furnace of Generator Unit 2, during the inspection of the seismic support brackets of the pipelines, it was found that 9 constant force support brackets failed in the hot section pipeline of the electric water heater, and 3 constant force support brackets failed in the main steam pipeline, which seriously threatened the entire start-up and trial operation of the generator unit.
