28、rain hole in the pump body or drilling andtapping a hole in the head for an external drain.6.1.4 Reservoir, (Item 1, Fig. 1).6.1.4.1 The reservoir shall be equipped with a removable baffle and a close fitting lid, all of stainless steel construction. Thereservoir can be square or rectangular (with a
29、 flat bottom) or cylindrical (with a spherical or cone shaped bottom) and must bedesigned so as to avoid air entrainment in the fluid.NOTE 2A suitable reservoir design is presented in Test Method D288200.6.1.4.2 To promote deaeration and thermal mixing of the fluid, the baffle shall be designed so t
30、hat returning fluid will followan indirect path from the return port to the outlet port.6.1.4.3 To avoid air entrainment, the reservoir shall be designed so that the return line enters well below the fluid level, fluidflow does not cascade over the baffle, and there will be a minimum of 15 cm of flu
31、id depth above the pump inlet line.6.1.4.4 Fluid ports may be added as required by the user for the installation of a low level switch, reservoir temperature sensor,bottom drain, and so forth.6.1.4.5 If the reservoir is positioned so that the contents cannot be visually checked for aeration by remov
32、ing the lid, a fluid-tightglass viewing port may be located in the side of the reservoir.6.1.5 Outlet Pressure Control Valve, Eaton-Vickers pressure relief valve (CT-06-C/3.4 to 13.8 MPa) with either manual orremote control (Item 8, Fig. 1).56.1.6 Temperature Control Device, suitable for controlling
33、 coolant flow to the heat exchanger to maintain test fluid at thespecified temperature (Item 11, Fig. 1).5Request Vickers publication I-3369-S for the relief valve service data. See http:/ 3 Conestoga USA, Inc., B1 Pump AssemblyD7043 1246.1.7 Temperature Indicator, (Item 2, Fig. 1) shall have an acc
34、uracy of 61C and shall have an appropriate sensor to monitorpump inlet temperature.6.1.7.1 To prevent a flow restriction near the pump inlet port, the temperature probe shall have a diameter of not more than 6mm.6.1.7.2 The test fluid temperature shall be measured within 10.2 cm of the pump inlet (D
35、imension C, Fig. 1). The sensing probeshall be inserted into the midpoint of flow.NOTE 3Some users have found the addition of a pump outlet temperature sensor to be a useful diagnostic tool. If used, it shall be suitable for13.8-MPa duty and should be placed in the high pressure line between the pum
36、p and the relief valve (Item 18, Fig. 1).6.1.8 Heat Exchanger, (Item 10, Fig. 1). The heat exchanger should be of adequate size and design to remove the excess heatfrom the test system when using the available coolant supply.NOTE 4It is suggested that a shell-and-tube-type heat exchanger, if used, s
37、hould be connected in reverse (the hydraulic fluid is passed through thetubes and not around them) so that the interior of the heat exchanger can be effectively cleaned between tests.6.1.9 Pressure Indicator, (Item 6, Fig. 1) to measure pump discharge pressure shall have an accuracy of at least 60.3
38、 MPa at13.8 MPa. The gauge shall be suitable for 13.8-MPa duty.6.1.9.1 The pressure indicator should be snubbed (Item 7, Fig. 1) to prevent damage from pulsations or sudden fluctuations ofsystem pressure.6.1.10 Filter Unit (Item 9, Fig. 1), 3-m (minimum Beta 3 ratio of 100) replaceable fiberglass el
39、ement with housing. Two newfilter elements are required for each test.6.1.10.1 The filter housing shall be non-bypassing and shall be provided with dual pressure gauges (Item 13, Fig. 1) or anothersuitable indicator to monitor pressure across the filter to warn of impending collapse of the element.6
40、.1.10.2 If dual pressure gauges are used to monitor filter pressure, the rated collapse pressure of the filter element should beknown. The collapse pressure should be within the range of the gage.6.1.11 Flow Measuring Device, (Item 12, Fig. 1) with an accuracy of at least 60.4 L/min.6.1.12 While not
41、 required, it is suggested that low-level, high-pressure, high-temperature, and low-flow safety switches beincorporated into the system.6.1.13 A check should be made to ensure that the flush and test fluid are not incompatible with hoses, seals, or any othermaterials in the system.NOTE 5The use of g
42、alvanized iron, aluminum, zinc, and cadmium should be avoided because of their high potential for corrosion in the presenceof many non-petroleum hydraulic fluids.6.1.14 Flexible Motor Coupling, (Item 4, Fig. 1).6.2 The various components of the test system shall be placed in the system as indicated
43、in Fig. 1.6.2.1 The test system shall be arranged and provided with necessary drain valves so that complete draining is possible with nofluid trap areas.6.2.2 Good hydraulics piping practices should be used when constructing the test system to avoid air ingestment points and flowrestrictions.6.2.3 T
44、he pump should be mounted so that its internal surfaces can easily be inspected and cleaned, alignment can be checked,and the operator has comfortable access when torquing the head.6.2.4 The reservoir shall be located above the pump so that the fluid level in the reservoir will be between 61 and 66
45、cm abovethe center line of the pump when the test system is fully charged with 19 L of test fluid (Dimension A, Fig. 1).6.2.4.1 The reservoir should be mounted so that it can be cleaned and filled with ease and the contents may be readily inspectedby removal of the reservoir lid.6.2.5 The inlet line
46、 (from the reservoir to the pump intake) shall have an internal diameter of at least 25 mm and shall have astraight horizontal run of at least 15 cm to where it connects to the pump inlet port (Dimension B, Fig. 1). If a hose is used, it shallbe rated for vacuum service. The B1 pump uses dual inlet
47、hoses with an internal diameter of 22 mm.NOTE 6Some users have found the addition of a compound pressure gage near the pump inlet port to be a useful diagnostic tool (Item 17, Fig. 1).However, exercise care to ensure that any ports added to the inlet line do not become air ingestment points.NOTE 7Th
48、e use of a solenoid valve, finger screen or other device which restricts pump inlet flow is discouraged. Inlet restrictions adversely affectpump performance.NOTE 8When tubing is used for the pump inlet line, some users prefer to use a radius bend instead of an elbow near the pump inlet. If used, the
49、straight run described in 6.2.5 shall be measured between the end of the bend and the pump inlet port. For optimal flow properties with 25 mm tubing,a 100-mm (4-in.) bend radius is recommended.6.2.6 The high pressure discharge line (from the pump to the pressure control valve) shall be rated for 14-MPa (2000-psi) dutyand have a minimum internal diameter of 15 mm. The B1 pump uses dual discharge hoses with an internal diameter of 10.4 mm.6.2.7 The fluid return line and fittings (from the pressure control
