Endurance bench for cartridges for taps

THE SOLUTION PROVIDED BY LF TECHNOLOGIES

Our client is a supplier of sanitary equipment (mechanical taps, thermostatic taps, shower columns, etc.), for kitchen, bathroom and shower. It is the market leader in the Nordic countries and the market leader in continental Europe.

Main functions

Objective

Design and construction of a hydraulic test bench to meet current standards with accurate monitoring of pressure, temperature, flow, force and torque measurements. Our client wishes to test its samples in order to estimate their life expectancy, performance and hydraulic characteristics.

Creation of a test set to perform endurance tests on 6 different products or samples. Need for simplicity and speed of testing.

Problematic Issues

Our customer needs to test the endurance of thermostatic cartridges of mechanical mixing valves. He wants to test several products simultaneously and independently. His request was for 6 test stations.

Solution and Result

Our engineers have created a hydraulic test system consisting of 6 test stations. These test machines operate independently and simultaneously. They measure pressure, temperature, flow rate, force and torque while evaluating the conformity of thermostatic cartridges of mechanical mixing valves to current standards.

The endurance test bench has a safety system that automatically stops the test in the event of a fault and protects the operators in the event of a leak in the product under test.

Our experts have developed software specific to this test machine. Easy to use, it automatically produces and edits test reports. The test bench can be controlled remotely and the transfer of information and documents is made easier.

Creation of a cartridge endurance test bench with a high degree of flexibility in the processing and analysis of sanitary components, meeting the standards governing the European markets.

Endurance bench incorporating a modular system that can test different types of mechanical cartridges independently of each other.

Presence of a booster on each station, in order to test the tightness at 16 bar
Measurement of accuracy, sensitivity, flow determination, etc.
Leakage measurement / Leakage calculation
Setting of temperatures, cartridge flow rates with torque or force measurement
Monitoring of temperature and supply pressure
Automatic report generation

Products tested

Mechanical mixing valve cartridge

A mechanical mixing valve cartridge is the element inside the mixing valve that regulates the mixture of hot and cold water (and therefore the temperature) and the flow rate.
