Maintenance of the system, except for replacing the assemblies or components other
than lamp assemblies will involve the assembly and disassembly of the photometer
assembly as a whole. Please pay attention to the following:
1 When disassembling the instrument, do not drag the cable with excessive force.
If necessary, you can disconnect the connection of some cables in advance. Do
not make any cable pressed, especially the cable under the photometer base.
2 When disassembling the instrument, do not press the air duct or conduct any
operation that might distort the air duct, otherwise the refrigeration plate might be
damaged.
3.2.2 Lamp assembly
3.2.2.1 Introduction
The lamp assembly is the light source of the instrument, providing energy source for
the detection system. Among the components of the lamp assembly, the lamp should
be replaced regularly, so when we design the system, we take the manual
replacement into consideration, taking the assembly as a whole connected with the
lamp base, fixing it with a long hand screw to facilitate manual disassembly.
3.2.2.2 Components and Structure
The basic structure of the lamp assembly is shown as figure 3-3.
Figure 3-3 Lamp assembly structure
3.2.2.3 Assembly and Disassembly of the Lamp Assembly
Lamp assembly is connected with lamp base assembly through lamp fixing screw
and aφ3 pin. (figure 3-2).
