According to the principle of moment balance steam-water
spring design.
Within the prescribed scope of load displacement, load torque and spring torque is always in balance.
Therefore, supported by constant crane pipeline and equipment displacement occurs, can get constant supporting force, will not bring additional stress to piping and equipment.
steam-water spring working principle and design principle: according to the moment balance the original design.
Within the prescribed scope of load displacement, load torque and spring torque is always in balance.
Therefore, supported by constant crane pipeline and equipment displacement occurs, can get constant supporting force, will not bring additional stress to piping and equipment.
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.
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.
spring factory before they go out of the steam-water setting, when installed on the pipeline and equipment, adjust the relevant thread, to fix the quotas for marketing off, the spring is the actual bearing design requirements of cold load.
