S53/54 Spectrophotometer Repair Manual

S53/54 spectrophotometer maintenance: Open cover inspection: When it is required to check the mechanical, optical path, power status of the machine, or when replacing the light source, it is necessary to open the cover for inspection, as follows: 1. cut the power. 2. Open the top cover of the wavelength knob and remove the wavelength knob. 3. Remove the two M4 screws on the front of the bottom of the instrument and flip up the top cover to easily view the various parts of the instrument. (There is a high voltage part at the bottom left of the instrument. Please do not operate with power.) Replace the power supply: This instrument uses the factory-corrected long-life precision combined light source. When replacing the damaged light source, you can use the following steps: 1. Open the top cover. 2. Remove the old light source assembly: Remove the light source cable, unscrew the positioning knurled screw of the light source holder, and carefully remove the light source assembly. 3. Install the new light source assembly in the reverse order of (2). 4. Turn on the power switch of the main unit, dial the black dome of the monochromator, and select the wavelength at 280nm to check whether the light source is centered.

Crushing Machine, in a word, is a kind of machine to grind large size material or granule to smaller sizes or powder. Based on different request, Crushing machine can be divided into different types. Based on different material, different crushing machines are considered to meet different request.

For grinder large material into smaller sizes, we can use coarse crusher: This machine is a hammering type mill used to pulverize drugs, chemical materials, food staff and other materials with medium hardness and low viscosity. It is suitable for the suitable for the production in middle and small-batches or sample experiments in laboratories. Materials are fed into the pulverizing chamber by a helical conveyer, and pulverized instead of other energies of other energies of revolving parts of the machine. .
The machine is simple in structure and the pulverizing chamber can be dismounted assemble and be dismounted and cleaned easily. All the parts in the chamber which contact materials are treated specially and corrosion resistama. As a result, in addition Any material ,drifted into grind chamber through feed bucket ,punched by knife edges and knife stands ,cut and grinded simultaneously by revolving and fixed knives, and due to the centrifugal force of revolving object ,automatically runs to exit

If we grind small particles to powder: The crusher mill machine is widely used in pharmaceutical, food, chemical, it can crush various of material.

The machine is made up of feeding material part and crush part, and dust collect part. Its coniguration is very briefness, all the parts which contact the material are made of stainless steel.
