Abstract
An injection pressure regulator testing system has a sleeve, a pressure source, and a power supply. The injection pressure regulator is inserted into a test chamber formed by the sleeve. The power source activates the injection pressure regulator for operation at a selected pressure level. The pressure source pumps hydraulic fluid into the test chamber. A determination is made as to whether the injection pressure regulator can achieve a selected pressure level.
Claims7
A method for testing an injection pressure regulator, comprising:
- sealably engaging an injection pressure regulator in a test chamber formed by a rigid sleeve, wherein the step of sealably engaging includes:
- sealably engaging a first O-ring of the injection pressure regulator against a first interface on an inside surface of the test chamber, and
- sealably engaging a second O-ring of the injection pressure regulator against a second interface on an inside surface of the test chamber:
- activating the injection pressure regulator for operation at a selected pressure level;
- pumping hydraulic fluid into the test chamber;
- and
- determining whether the injection pressure regulator can achieve the selected pressure level.
A method for testing an injection pressure regulator comprising:
- placing the injection pressure regulator in a sleeve having a test chamber in fluid communication with the injection pressure regulator;
- sealably engaging at least one O-ring disposed on the injection pressure regulator against at least one interface on an inside surface of the test chamber;
- activating the injection pressure regulator for operation at a selected pressure level;
- pumping hydraulic fluid into the test chamber;
- venting hydraulic fluid out of the test chamber through the injection pressure regulator;
- and
- maintaining the selected pressure level In the test chamber.
