1.Introduction
Model ZNS-5B Low Pressure Filter Press is the most effective means of determining filtration properties of drilling fluids and cement slurries. All Low Pressure Filter Press assemblies consist of these items:
- Mud reservoir mounted in a frame
- Pressure assembly and regulator
- Filter paper
- 25 ml graduated cylinder
Measuring filtration behavior and wall-cake building characteristics of a mud is essential to drilling fluid control and treatment. The characteristics of filtrate, such as oil, water, or emulsion content are also important. The types and quantities of solids in the fluid and their physical and chemical interactions affect these characteristics. Temperature and pressure affect the physical and chemical interactions. Performing tests at both low pressure/low temperature and high pressure/high temperature is necessary, and these testing conditions require different equipment and techniques.
The basic filter press has a cell assembly constructed of stainless steel or aluminum material and includes the required screens and gaskets.
Working pressure is 0.69MPa and the filtering area is 45.6cm², as specified in API
standard.
| Compressed oxygen should not be used as a pressure source. Fire and explosion hazards exist when using oxygen. |
