Hydraulic test benches
Endurance bench for mechanical cartridges
Technical description
Main functions
The LifeCartM is an endurance test bench to verify the life, performance and hydraulic characteristics of mechanical cartridges for mixing valves.
Tests are performed to meet standards such as EN 817 and NF 077
- Fidelity measurement, sensitivity, flow determination, etc.
- Leakage and static pressure tests at 16 or 25 bar
- Temperature adjustment with torque measurement
- Flow rate adjustment with force measurement
- Temperature and supply pressure measurement and monitoring
- Endurance cycles
- Automatic report generation
Operating mode
The equipment is a test bench equipped with several modules (from 2 to 6), designed to carry out performance and endurance tests of mechanical cartridges of mixing valves.
Each cartridge under test is mounted in a specific tool, connected to a hot and cold water supply and a piped mixed water outlet. The cartridge control lever is automatically operated by 2 actuators (1 rotary and 1 linear), capable of performing movements with position, speed and torque/force control. In addition, each module is equipped with a static pressure generator, allowing leakage and mechanical resistance tests to be carried out at pressures of up to 16 bar or 25 bar.
The bench is connected to two hot and cold water inlets. The temperature generation is done outside the bench. The hot and cold water supply pressures are provided either directly from the mains supply to the bench or by an external pressure generator (optional).
The software performs all performance and endurance tests by simple programming.
