Description
Bladder air/water pressure cylinders
The Bladder air/water cylinders are used to deliver pressurized water up to 1000 kPa to triaxial cells by the pressure distribution panels. The main advantages from using this apparatus are:
- High degree of accuracy
- Extremely simple to operate
- Future expansion of system very easy and relatively low cost
- Bladder enables the use of de-aired water
- Large reservoir to cope with long term tests and large samples
The cell, made from transparent acrylic tube, flanged between two light alloy discs, incorporate a rubber membrane and can operate continuously at a pressures up to 1000 kPa. The unit acts as a reservoir/interface between compressed air, used as a pressure source and water used as the pressurizing medium in the triaxial cell. The Bladder air/water cylinders have to be completed with the 28-WF4330 or 28-WF4331 two or three lines distribution panel depending on the application.
- Dimensions: 178 mm dia. x 410 mm high
- Weight approx.: 5.8 kg
Pressure distribution panels
Two models available: 28-WF4330 for two pressure lines and 28-WF4331 for three pressure lines. They include precision air regulators, pressure outlets and quick release fittings.
They have to be completed with a digital gauge (see accessories, model 28-WF4330/2).
- Dimensions/weight approx.:
510x454x184 mm (28-WF4330)/10 kg
690x454x184 mm (28-WF4331)/15 kg
