Variable is mainly composed of cylindrical helical
spring, steam-water spring displacement dashboards, shell and parts such as elastic nut.
steam-water variable spring according to the different methods of installation, can be divided into A, B, C, D, E, F, G seven type.
type A -

Single ear suspension type;
- C type

-
Under the adjusting suspended type;
F -

Parallel suspension type;
note:
1, the installation load, provided by the factory according to user's use, under the two pieces of locating piece will spring the instructions of the steam-water plate fixed on the corresponding position and installation load, make the steam-water spring temporarily in a rigid state;
2, pipe after cleaning, hydrostatic test, remove the upper and lower locating piece, can will pipe in use;
3, pipes, began to run, first check whether positioning block or dismantled, check the dashboard from the installation in the process of the displacement of the load to the working load for jam phenomenon;
4, pipeline into normal operation, check the steam-water spring when working load displacement is consistent with the design.
Pipe after stop running, check whether the dashboard is reset to install the load position.
Check the spring hanger stick to sex, etc.
with constant force spring hanger is designed according to the moment balance principle of a mechanical device.
Can be suspension and support through its pipeline and equipment, at this point, when the pipeline or equipment to produce displacement, as long as the load displacement at the pre-arranged pick-up, no matter how much its displacement change, they can through the constant force spring support and always get constant support.
Which will not bring new additional pressure to piping or equipment, so you can avoid causing significant equipment and safety accidents.
constant condole commonly used in need to reduce the stress, displacement, such as power station boiler of power plant steam, water, smoke air ducts and burner, such as suspension parts, and petrochemical equipment, and other places need to reduce the displacement stress.
For the study, researchers defined Yongqiang as strategies to foster some social good, including programs that benefit community engagement, diversity, the environment, human rights and employee relations.
