Some problems that should be considered in the selection of constant force spring support and hanger

1 category selection

A certain type of constant force spring hanger shall be taken into consideration. The installation space, dimensions and layout of the pipe and hanger shall be taken into consideration

Requirements for body arrangement.

PH flat type constant force spring hanger is suitable for big horizontal space. LH vertical constant force spring hanger is suitable for horizontal space

Not ample and the hanger should be vertically arranged to increase the overall beauty of the equipment; the ZH seat type constant force spring is suitable for placing the support and hanger

A place on a support member, above, or below a pipe or device.

2 type selection

There are eleven types of this standard. According to the fixing or hoisting way of the hanger, there are two hanging point hangers, single hanging point hangers and pedestal hangers.

There are four kinds of hanger points: PHA, PHE, LHA and LHE. There are four types of hanger points: PHB, PHC, LHB and LHC

PHD, ZHA, ZHB, three kinds.

The double hanging point hanger is easy to install and reliable in fixation; the single hanging point hanger is easy to install and can be rotated freely in case of obstruction

The block type hanger can be placed directly on the support component according to the user's needs, but the PHD type needs a larger horizontal space.

In this standard, each type of constant suspension support bolt is allowed to swing about 4 degrees relative to the vertical direction so that the hanger fits the water of the pipe

Horizontal displacement. When the pipeline moves from the cold state to the hot state (that is, the installation state to the working state), the constant displacement spring hanger is connected with the pipe

The cold installation position of the boom should be fully considered after the horizontal displacement and displacement direction so as to make the hanger position in the working state most suitable

(in a vertical state).

When the type of support and hanger and the fixation or support way of support and hanger are selected, the type of support hanger can be determined.
