Description

NASA/GRC plans to issued a Request for Quotation (RFQ) for: HYDRAULIC PUMP SYSTEM WITH 300 PSI AT 30 GPM -- (1 EACH) Salient Characteristics for Hydraulic Pump System 1) General Description: The hydraulic pump system (HPS) is required to provide oil supply to Government Owned High Cycle Fatigue Test Systems. This test system is capable of performing fatigue tests up to 1000 Hz on material test specimens and are located in a single room. The acoustic noise emitted by the HPS must be maintained at low levels to reduce the overall noise in the room during operation of the high frequency test machines. Innovative techniques to reduce or compensate the acoustic noise emitted by the HPS are critical to the performance. 2) The Hydraulic Pump System shall have the following operational features: 2.1) Operating pressure that is not less than 3000 psi at 30 GPM 2.2) Reservoir capacity of at least 90 Gallons 2.3) Return oil filtration of 3 microns 2.4) Control Voltage of 24 V DC 2.5) Compatible with 440 VDC, 3 Phase, and 60 Hz main power supply 2.6) Water-cooled, oil heat exchanger 2.7) Noise level less than 65 dBA at the test rigs, which will be located about 6 feet from the HPS 3) The HPS shall also have the following characteristics: 3.1) In order to locate the HPS in the same room as the high cycle fatigue testing machines, the HPS shall conform to the following dimensions: Length less than 65 inches, Height less than 60 inches and Width less than 36 inches. 3.2) The HPS shall contain the necessary high-pressure hoses so that it can be connected to the government-owned, MTS Hydraulic Manifold Model No. 293.12A-01. A minimum hose length of 6 feet is required. 3.3) Robust, piston-type, pressure-compensated, variable displacement pump is required to provide prolonged service life under continuous operating conditions. Fixed displacement pumps are not acceptable due to limited durability under continuous operating conditions. 3.4) A directly coupled motor with a power rating of at least 60HP is required to drive the pump. 3.5) A pump/motor configuration submerged in hydraulic oil is required to muffle the noise generated by the pump/motor assembly and to capture the heat generated. 3.6) An oil to water heat exchanger that can efficiently remove the heat from the oil and minimize discharge of the heat to the surrounding areas is required. The heat exchanger shall have sufficient water flow capacity to accept incoming cooling water with temperatures as high as 90 0F. The heat exchanger shall be made from durable Cu/Ni material. 3.7) The HPS shall be equipped with temperature-based, water-control valves to regulate water consumption. The HPS shall contain a pressure line manifold with a relief valve and a port for sampling hydraulic oil periodically. 3.8) Due to the limited space available for the HPS, an integral design consisting of the oil reservoir, pump/motor system, and heat exchanger is preferred. The oil reservoir shall be manufactured from a rust resistant material such as aluminum. 3.9) The HPS shall be housed in a NEMA approved enclosure and shall contain all the necessary control switches for starting and stopping the pump/motor system and indicators for low oil level, over temperature, and dirty filter in clearly visible locations. 3.10) Base of the HPS shall provide sufficient clearance to handle the unit with a fork lift-truck. 3.11) Design of the HPS shall confirm to all the appropriate US OSHA requirements. 4) Deliverables: 4.1) HPS compatible with the specifications listed in sections 1 to 3. 4.2) One set of manuals, in the English Language shall be provided which cover: a) A user reference manual having a description of the theory of operation and detailed drawings and schematics. b) An operation manual containing system operation and instructions. c) Manufacturer's manuals describing components not manufactured by the Contractor and used in the HPS. 4.3) Desired date of delivery of the HPS is within 60 days after receipt of order. The required date of delivery for the HPS is no later than 90 days after receipt of order. 4.4) The Contractor shall assemble, install, and check-out the equipment provided under the contract at NASA Glenn Research Center within thirty days after delivery. This procurment is being conducted under the Simplified Acquisition Procedures (SAP). The Provisions and clauses in the RFQ are those in effect through FAC 97-21. The NAICS code and the small business size standard for this procurement are 334519 and 500, respectively. DPAS rating for this procrement is DO-C9. NASA/GRC intends to purchase the item from MTS Systems Inc. THIS IS A SOLE SOURCE. The pumping system detailed is compatible with existing high cycle fatigue testing equipment located at Glenn Research Center. The same vendor manufactures the testing equipment and hydraulic pumping system. The NASA test program will be used to develop, calibrate and verify a CMC lifing model for candidate ceramic fiber reinforced ceramic matrix composite (CMC) systems. MTS Systems Incorporated, is the sole supplier of the existing test equipment and compatibility with the specified pumping system is essential. The statutory authority permitting other than full and open competition is Federal Acquisition Regulation (FAR)6.3.3(c). This notice is for information purposes only. The Government intends to acquire a commercial item using FAR Part 12. An ombudsman has been appointed -- See NASA Specific Note "B".
