30 -- HYDRAULIC POWER SUPPLY SOL 9BE3327520P DUE 042195 POC WENDY BOUDREAUX, Tel:713-483-5338 Contracting Officer:LISA REA, Tel:713-483-8395 A hydraulic power supply (HPS) which will be a portable, self-contained system that will connect to hydraulic lines and a training facility, provided by others, at the Johnson Space Center, Houston, Texas. It will provide 3000 psi and a minimum of 70 gpm per pump unit; two pump units are required for redundancy, both are in one housing. Capability shall exist to develop 6,000 psi, at no flow (deadhead), for certification testing of the entire system. The fluid used will be Mobil DTE-24 hydraulic fluid. The HPS shall consist of motors, pumps, and associated hardware to provide the specified hydraulic power, as well as sound enclosures and heat exchange devices to meet requirements. The electrical power will be 460 VAC, 3 phase, and 600 amps. A chilled water supply will be available at 45 degrees and at a 40 GPM Maximum. The HPS will be located in an existing PEAF panel enclosure, with outside air flow, adjacent to building 9NE. Positioning the unit and connection of electrical power, chilled water, hydraulic lines, and remote control wiring will be by others. The HPS shall operate unattended from a main control panel on the unit and/or a remote panel. A key switch in the main panel will select whether the local or remote panel is in control for all functions but ''emergency stop'', which is always operable from both panels. The HPS shall have a noise rating of 80 db at 5 feet from the source. The proposed contract is 100% set aside for small business concerns. --j) Hour meter on each pump k) Single point of electrical supply (460 VAC); supply by others Remote Control Panel: a) On/off switch/indicator for each pump b) Pump hi/low pressure operation switch/indicator (each pump) c) ''Emergency off'' switch - see Main Control Panel d) Dirty filter indicator (activates from any filter) e) Low hydraulic fluid level indicator f) Over temperature indicator for hydraulic fluid g) 24 VDC control voltage operation h) 19'' rack mount; envelope is 3 1/2'' tall x 19'' x 15 1/4'' deep i) Interface of the two panels will be in two each 400', twisted pairs, --1 --Houston, Johnson Space Center --September 15, 1995.
