Mechanical Industry Standard of the People's Republic of China
Support for Electrostatic Precipitator
Type and Basic Parameters
Subject Content and Scope of Application
This standard specifies the code and basic parameters of the support for electrostatic precipitator, JB5912.1-91
This standard is applicable to the support with working temperature of -40~+80℃. Other supports for large buildings such as pipelines, bridges, heat exchangers, etc. can also be used for reference.
Symbols and Explanations
A: Width of base;
B: Distance between the anchor bolt holes of the base;
D: Outer diameter of dust cover;
H: Support height;
H1: Height from the bottom of the base to the top of the middle seat; d: Diameter of the anchor bolt hole and the top plate bolt hole;
C. Length of the top plate of the sliding support;
F: Width of the top plate of the sliding support;
E Amount of unilateral movement.
3 Classification
Bearings can be divided into two types according to the friction type: rolling type and sliding type. According to the moving direction, they can be divided into three types: unidirectional, universal and fixed. See Figures 1 to 6.

The code of the bearing consists of three parts: the front section, the middle section and the rear section. The front section represents the bearing, which is represented by Z. The middle section represents the friction type and the moving direction, which is represented by the code specified in Table 1. The latter part indicates the vertical bearing capacity and unilateral movement, expressed in six Arabic numerals (except for fixed bearings). The first four digits indicate the vertical bearing capacity (in kN). If the number is less than four digits, the first few digits are filled with zeros, and the last two digits indicate the unilateral movement (in mm). Fixed bearings use four Arabic numerals to indicate the vertical bearing capacity. The expression is as follows: ZbZxz.net
