Customer
Our client is a specialist in the design and manufacture of seals for industry.
Tested product
Seals
A seal is a device that ensures the tightness between two elements. This means that it prevents leakage of fluids (liquid, gas).
Objective
The proposed equipment is a fluid pressure and temperature control system for connection to the test chamber of an existing hydraulic bench.
Problematic issues
Regulation of the temperature and pressure of the fluid flowing past the seal to be tested.
The fluid can be water or oil and must be able to be changed while minimising "dead" volumes, i.e. by limiting the quantity of residual fluid during a change.
Solution and result
The equipment studied by our technicians is a self-contained system that is easily transportable.
Hydraulic circuit:
The system ensures pressure regulation thanks to a static pressure generator with a servo-controlled plunger.
The temperature regulation is ensured by a heat exchanger between the main circuit and a secondary oil circuit.
The circulator and static pressure generator are designed to minimise "dead" volumes. The plungers are controlled by linear actuators.
The circulator and generator are connected to the test chamber by hoses.
Static pressure generator:
The static pressure generator consists of a plunger. The pressure is regulated by the movement of the plunger.
Temperature control circuit:
The temperature control circuit heats or cools the secondary circuit. It is controlled by a PC equipped with software developed for this bench, which allows, among other things, to save the measurements in spreadsheet format and to use them in Excel.
All safety functions are managed by a dedicated safety PLC.
The pressure and temperature control circuit is designed to connect automatically to the test chambers supplied by the customer.
