62 9 Pump Mounting NOTE: The 'Nudge' control (see Figure 412) allows the operator to rotate the drive round to any position in small steps This is useful for positioning the drive to allow coupling fixing screws to be tightened or loosened with ease 91 General This section of the manual contains general information about mounting typical pumps on the test stand Accessory packages are available for mounting and testing most common rotary and in-line pumps 92 Mounting a Pump to the Test Stand CAUTION! The operator must ensure the correct pump mounting plates / brackets, injectors and high pressure pipes are used Incorrect setting of the drive can cause pump seizure Operating Tips For best results minimise run-out of the test stand drive coupling When using the pump coupling with 10mm thick drive dogs, use the 1mm spacer (1) opposite the clamping screw 12mm and 20mm thick dogs do not need a spacer When the pump drive is connected to the test stand drive make sure the drive dogs are horizontal and slide the pump coupling into the correct slot in the drive Leave a 05mm to 1mm gap between the pump and test stand couplings Shake the test stand coupling to settle it into a concentric position and then tighten the clamping screws to 25Nm You can use the Nudge facility to help rotate the pump to achieve this easily Figure 91 Drive Coupling with Spacers 60

63 921 Injector Mount The AVM can be supplied with a range of different injectors which may be fitted using the appropriate accessories 922 Mounting a Rotary Pump The anti-backlash coupling fitted to this test stand will accept pumps with both supported and unsupported shafts First determine the pump type CAUTION: Incorrect setting of the anti-backlash coupling is likely to cause damage to the pump and may result in drive shaft seizure 9221 Unsupported Drive Pumps Refer to Figure 92 CAUTION: Fit drive guide Part No before testing unsupported drive pumps The majority of rotary pumps may be secured with the quick release clamps, however the adaptor plate has a hole pattern which will allow pumps to be bolted directly to the plate 9222 Supported Drive Pumps CAUTION: DO NOT fit the central guide when testing supported drive pumps The antibacklash coupling must allow the drive to float If a central guide is already fitted, insert a 8 mm threaded screw into the central guide, as shown in Figure 92 and withdraw the guide Refer to Table 41 to select the appropriate mounting plate for the pump to be tested Fit the mounting plate and clamp plates as shown in Figure 93 NOTE: Couplings such as ADC 223 have screws in their outer diameter ADC 240 is a safety guard as well as an adaptor It is designed to trap the screws if they come loose and must be used for any coupling of this nature 61
