Foam stability evaluation device under high temperature

1. Functions of the instrument

Used for evaluating the performance of foaming agents under high temperature conditions.

2. Main technical parameters:

Work pressure: 20Mpa

Working temperature: Room temperature~200 ℃

Power: around 6KW

Power supply: AC 380V~220V

2. The foaming agent evaluation device consists of the following systems:

1、 Gas injection metering system

a、 One route is used to inject a certain amount of Co2 high-pressure gas into the main body. The system consists of a refrigeration system, coils, storage tanks, hand-operated metering pumps, pressure gauges, etc.

1. Co2 hand cranked metering pump: working pressure 40Mpa

2. Storage tank: 2000ml/16Mpa

3. Refrigeration system: 90~-5 ℃

4. Pressure gauge: 16Mpa

b、 The other route is also used to inject a certain amount of high-pressure gas into the main body. The system consists of a gas booster pump, an air compressor, a high-pressure storage tank, a pressure regulating valve, a pressure gauge, etc.

1. Gas booster pump: working pressure 40Mpa

2. High pressure gas storage tank: 3000ml/32Mpa

3. Pressure regulating valve: inlet pressure 32Mpa, outlet pressure 0-20Mpa

2、 Foaming agent, oil, water injection system

Used to inject a certain volume of foaming agent, oil, water, etc. into the main body. Inject using a hand pump.

3、 Main body part

Main working dimensions: φ 60 (inner diameter) × 450mm

Work pressure: 20Mpa

Working temperature: Room temperature~200 ℃

The main body is designed with two to three visible high-voltage observation windows from top to bottom, which are equipped with scales for easy observation of high readings. The main body is equipped with heating, insulation, and temperature control systems.

4、 Temperature control measurement system

To ensure uniform temperature, the heating and temperature control method is divided into two stages

Temperature control range: room temperature~200 ℃

Accuracy: ± 1 ℃

The main body is equipped with two temperature measuring probes to measure the working temperature.

5、 Pressure measurement system

The pressure is measured using a pressure transmitter with a range of 25Mpa and an accuracy of 0.25% F · S. The pressure value can be directly displayed by the secondary instrument.

6、 Cleaning system

Used for cleaning the main body and pipeline parts, consisting of a hand pump, cleaning agent tank, etc

1
Hand cranked pump: 40Mpa

2
Cleaning agent tank: 2000ml/16Mpa, piston type

7、 Pipeline process system

The links for each part of the system are made of φ 6 × 1mm stainless steel pipes, with a pressure resistance of 25Mpa.

8、 Bracket, control panel

Used for installing various components and control instruments
