The purpose of using potassium ions in drilling fluids is to stabilize shale and inhibit swelling clays. Therefore, the potassium ion concentration must be accurately determined in order to control the performance of the drilling fluid. This hand-cranked centrifuge is used to determine the potassium ion content in drilling fluid filtrates when the potassium ion concentration exceeds 5,000 mg/L or the KCl concentration exceeds 3.5 lb/bbl. After precipitating the potassium ions with perchlorate in the centrifuge tube, the volume of the precipitate is measured, and the potassium ion content is read from a standard calibration curve.

4.Instrument Structure and Principle

The instrument consists of three components: filter cartridge, funnel, and glass measuring cylinder.

The filter cartridge is equipped with a (200 mesh) stainless steel mesh in the middle, with a pore size of 0.074mm.

A glass measuring cylinder is a glass measuring cylinder marked with a scale indicating the volume of the sample to be added (30ml). The percentage of sand content can be directly read, and there is a percentage scale line from 0 to 20 marked on this glass measuring cylinder.

This series of products is a gas pressure reduction output device. It is suitable for pressure regulation of various gas-using equipment. The manifold can be connected to compatible large gas cylinders, medium gas cylinders, and other gas source
devices. By adjusting the two sets of pressure reducing valves, output gas at two different pressures within the rated range can be obtained. Each set of pressure reducing valves is equipped with a set of safety valves, which provide automatic overload protection (pressure relief) in the gas supply pipeline. This manifold series comes with 1 to 4 output hoses, which users can select according to their needs. The gas source manifold is mainly used as a supporting component for various drilling fluid analysis instruments produced by our factory that require gas source control.

1.5 Zero calibration function.

1.6 The instrument can be connected to a computer for operation, displaying    measurement curves, and allows optional printing as needed.

1.7 Equipped with a double sealing mechanism, the instrument minimizes gas corrosion on the measuring bearing (85 bearing) during operation, thereby extending the service life. It represents an advanced measuring instrument.

1.8 The instrument is made of corrosion-resistant stainless steel. The measuring sleeve can be rotated in reverse, and after use, it can be easily cleaned and maintained.

1.9 The instrument supports three display languages: Chinese, English, and Russian.
