30、ngular (with a flat bottom)or cylindrical (with a spherical or cone shaped bottom) andmust be designed so as to avoid air entrainment in the fluid.NOTE 2A suitable reservoir design is presented in Test MethodD2882 00.6.1.4.2 To promote deaeration and thermal mixing of thefluid, the baffle shall be d

31、esigned so that returning fluid willfollow an indirect path from the return port to the outlet port.6.1.4.3 To avoid air entrainment, the reservoir shall bedesigned so that the return line enters well below the fluidlevel, fluid flow does not cascade over the baffle, and there willbe a minimum of 15

32、 cm of fluid depth above the pump inletline.6.1.4.4 Fluid ports may be added as required by the user forthe installation of a low level switch, reservoir temperaturesensor, bottom drain, and so forth.6.1.4.5 If the reservoir is positioned so that the contentscannot be visually checked for aeration b

34、llingcoolant flow to the heat exchanger to maintain test fluid at thespecified temperature (Item 11, Fig. 1).6.1.7 Temperature Indicator, (Item 2, Fig. 1) shall have anaccuracy of 61 C and shall have an appropriate sensor tomonitor pump inlet temperature.6.1.7.1 To prevent a flow restriction near th

35、e pump inletport, the temperature probe shall have a diameter of not morethan 6 mm.6.1.7.2 The test fluid temperature shall be measured within10.2 cm of the pump inlet (Dimension C, Fig. 1).

36、lief valve service data. Seehttp:/ 3 Conestoga USA, Inc., B1 Pump AssemblyD7043 174NOTE 3Some users have found the addition of a pump outlettemperature sensor to be a useful diagnostic tool. If used, it shall besuitable for 13.8 MPa duty and should be placed in the high pressure linebetween the pump

37、 and the relief valve (Item 18, Fig. 1).6.1.8 Heat Exchanger, (Item 10, Fig. 1). The heat exchangershould be of adequate size and design to remove the excessheat from the test system when using the available coolantsupply.NOTE 4It is suggested that a shell-and-tube-type heat exchanger, ifused, shoul

38、d be connected in reverse (the hydraulic fluid is passed throughthe tubes and not around them) so that the interior of the heat exchangercan be effectively cleaned between tests.6.1.9 Pressure Indicator, (Item 6, Fig. 1) to measure pumpdischarge pressure shall have an accuracy of at least 60.3 MPaat

39、 13.8 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 fluctua-tions of system pressure.6.1.10 Filter Unit (Item 9, Fig. 1), 3 m (minimum Beta 3ratio of 100) replaceable fiberglass element

Twonew filter elements are required for each test.6.1.10.1 The filter housing shall be non-bypassing and shallbe provided with dual pressure gauges (Item 13, Fig. 1)oranother suitable indicator to monitor pressure across the filterto warn of impending collapse of the element.6.1.10.2 I

41、f dual pressure gauges are used to monitor filterpressure, the rated collapse pressure of the filter element shouldbe known. The collapse pressure should be within the range ofthe gage.6.1.11 Flow Measuring Device, (Item 12, Fig. 1) with anaccuracy of at least 60.4 Lmin.6.1.12 While not required, it

42、 is suggested that low-level,high-pressure, high-temperature, and low-flow safety switchesbe incorporated into the system.6.1.13 A check should be made to ensure that the flush andtest fluid are not incompatible with hoses, seals, or any othermaterials in the system.NOTE 5The use of galvanized iron,

43、 aluminum, zinc, and cadmiumshould be avoided because of their high potential for corrosion in thepresence of 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 beplaced in the system as indicated in Fig. 1.6.2.1 T

44、he test system shall be arranged and provided withnecessary drain valves so that complete draining is possiblewith no fluid trap areas.6.2.2 Good hydraulics piping practices should be used whenconstructing the test system to avoid air ingestment points andflow restrictions.6.2.3 The pump should be m

45、ounted so that its internalsurfaces can easily be inspected and cleaned, alignment can bechecked, and the operator has comfortable access when torqu-ing the head.6.2.4 The reservoir shall be located above the pump so thatthe fluid level in the reservoir will be between 61 cm and 66 cmabove the cente

46、r line of the pump when the test system is fullycharged with 19 L of test fluid (Dimension A, Fig. 1).6.2.4.1 The reservoir should be mounted so that it can becleaned and filled with ease and the contents may be readilyinspected by removal of the reservoir lid.6.2.5 The inlet line (from the reservoi

47、r to the pump intake)shall have an internal diameter of at least 25 mm and shall havea straight horizontal run of at least 15 cm to where it connectsto the pump inlet port (Dimension B, Fig. 1). If a hose is used,it shall be rated for vacuum service. The B1 pump uses dualinlet hoses with an internal

48、 diameter of 22 mm.NOTE 6Some users have found the addition of a compound pressuregage 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 linedo not become air ingestment points.NOTE 7The use of a solenoid valv

49、e, finger screen or other devicewhich restricts pump inlet flow is discouraged. Inlet restrictions adverselyaffect pump performance.NOTE 8When tubing is used for the pump inlet line, some users preferto use a radius bend instead of an elbow near the pump inlet. If used, thestraight run described in 6.2.5 shall be measured between the end of thebend and the pump inlet port. For optimal flow properties with 25 mmtubing, a 100 mm (4 in.) bend radius is recommended.6.2.6 The high pressure dis
