With constant force
spring hanger is a mechanical device is designed according to the principle of moment balance.
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.
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.
the variable type spring hanger has four big series, mainly by the northwest electric power design institute of design of T1, T2, T3, T4, T5 series, east China electric power design institute of design of TH1, TH2, Tspan type series, the TD series (
JB / J8130。
2 -
1999).
And chemical design institute design VS series, the series of the basic features, the same bearing capacity for Dan - 20
21000daN。
Structure mainly pendant, supporting type and parallel suspension bearing type.
steam-water variable spring is mainly composed of cylindrical helical 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.
