Test method for hydraulic equipment and analyzer for hydraulic equipment

摘要

A method for testing an hydraulic device of an hydraulic control system, the system having a source of hydraulic fluid under pressure and a fluid reservoir, and the device having a fluid inlet which is releasably coupled to the source when the system is in operation, a fluid outlet which is releasably coupled to the reservoir when the system is in operation, and an element which restricts fluid flow between the inlet and the outlet, by: halting operation of the system; providing a portable analyzing apparatus having a supply of hydraulic fluid, an outlet conduit, a unit for supplying hydraulic fluid under pressure from the supply to the outlet conduit, a return conduit communicating with the supply, a fluid pressure monitor connected to the outlet conduit, and a fluid flow monitor in the return conduit; disconnecting the fluid inlet of the device from the source and connecting that fluid inlet to the outlet conduit; disconnecting the fluid outlet of the device from the reservoir and connecting that fluid outlet to the return conduit; placing the unit for supplying hydraulic fluid under pressure into operation for supplying hydraulic fluid under pressure to the outlet conduit; and monitoring the fluid pressure in the outlet conduit and the flow of fluid through the return conduit with the monitors.
