The water outlet of described pump 10 is connected with outlet pipe slip joint 50, and institute's outlet pipe slip joint 50 is connected with rising pipe assembly 60 away from one end of pump 10, and outlet pipe slip joint 50 is flexible telescopic joint.Described flexible telescopic joint is contracting Bellows expansion joint or rubber expansion joint.In order to prevent vibration possible on rising pipe assembly 60 and dynamic changes process on pump 10, by flexible telescopic joint, pump 10 and rising pipe assembly 60 are coupled together, the harm of expanding with heat and contract with cold can be got rid of, simultaneously also can vibration to greatest extent between separate pump 10 and rising pipe assembly 60 and various dynamic changes process, pump 10 is avoided to occur slippage further, stressed more reasonable, reliability is higher, and without the need to additionally adding anchor block, reduce installation space to greatest extent, save Equip-ment manufacture and installation cost.
As shown in Figure 1, described rising pipe assembly 60 comprises diffusing tube 610, first valve 620, outlet pipe 630, second valve 640 and the water outlet wall-passing pipe 650 that connect successively, described diffusing tube 610 is conical pipe, the small end of diffusing tube 610 is connected with described outlet pipe slip joint 50, and described first valve 620, second valve 640 supports respectively by the first buttress 660, second buttress 670.Diffusing tube 610 and the first valve 620, outlet pipe 630, second valve 640 and water outlet wall-passing pipe 650 are rigidly connected integral, and water outlet wall-passing pipe 650 is fixed on anchor block 2.Described pump mounting structure also comprises inlet pipeline assembly 70, described inlet pipeline assembly 70 comprises the eccentric pipe 710, intake pipe slip joint 720, the 3rd valve 730 and the water inlet wall-passing pipe 740 that connect successively, described eccentric pipe 710 is connected with the water inlet of described pump 10 away from one end of intake pipe slip joint 720, and described 3rd valve 730 is supported by the 3rd buttress 750.Pump 10, eccentric pipe 710 and the 3rd valve 730, water inlet wall-passing pipe 740 couple together by intake pipe slip joint 720, water inlet wall-passing pipe 740 is fixed on anchor block 3, if the amount of expanding with heat and contract with cold is negligible on eccentric pipe 710, water inlet wall-passing pipe 740, then intake pipe slip joint 720 can select the rigid telescopic joint with force-transfer characteristic, can strengthen pump 10 so further in the resistant slide ability importing and exporting direction; If the amount of expanding with heat and contract with cold can not be ignored on eccentric pipe 710, water inlet wall-passing pipe 740, then intake pipe slip joint 720 also can select flexible telescopic joint, prevents the pipeline stress that expands with heat and contract with cold excessive and destroy.
As shown in Figure 3, described pump mounting structure also comprises basic embedded part 80, and the bottom of described base 20 is welded with basic embedded part 80, and base 20 and basic embedded part 80 are cast in concrete pedestal 1.Described pump 10 is fixedly linked by pump pin retaining screw 90 and base 20.Arrange like this and can reinforce base 20, improve further pump 10 and the anti-horizontal shear of base 20 and the ability of slippage.After concrete pedestal 1 has been constructed, first by base 20 and basic embedded part 80 welded together at the scene, then be poured in concrete pedestal 1 by back-grouting, and then pump 10 is installed on base 20, the fine setting of substantially horizontal can be carried out to it by the first thrust piece 30, second thrust piece 40 in the process of installing, then lock pump pin retaining screw 90 and the first fixing bolt 320, second top, top fixing bolt 420, be subject on base 20, slippage to occur under the effect of external force load to prevent pump 10.
When pump 10 runs, the force value on inlet pipeline assembly 70 and rising pipe assembly 60 as shown in Figure 1.Wherein P0 is pump 10 suction pressure, and this value is general less, and be even likely negative pressure, therefore, the used load of inlet pipeline assembly 70 pairs of pumps 10 can be ignored.P1 is the pressure that spues of pump 10, and P2 is the interior pressure of outlet pipe 630, and P3 is the interior pressure of water outlet wall-passing pipe 650.The working condition of pump 10 under various operating mode is as follows:
1), under operating mode of starting shooting, the first valve 620 and the second valve 640 are closed, and discharge opening pressure P 1 increases to the maximum pressure that spues of pump 10 gradually by 0.In this process, P2 and P3 pressure is always 0.The maximum horizontal thrust F1 that then pump 10 bears under start operating performance is the product in P1 and outlet pipe slip joint 50 pressure cross section.Now, if the frictional force between pump pin and ram pack is less than horizontal thrust F1, then the first thrust piece 30 will play the effect preventing pump 10 slippage, and the intensity of the first thrust piece 30 and rigidity can carry out suitable design according to the size of horizontal thrust load.
2) shut down under operating mode, now pressure P 1, P2, P3 can produce certain pressure difference because of the closing sequence of the first valve 620, second valve 640 and pump 10 and closing velocity thereof.The piping load that this pressure difference produces likely points to the water inlet direction of pump 10, also likely points to the water outlet direction of pump 10.Because the outlet pipe slip joint 50 between pump 10 and diffusing tube 610 does not have intermal force for flexible telescopic joint, therefore, on the anchor block 2 that the piping load that this first valve 620, second valve 640 pressure at both sides difference produces acts on completely, and can not be delivered on pump 10.
3) under operating mode of expanding with heat and contract with cold, comparatively far away for anchor block 2 mounting point, the equipment operating environment temperature difference is comparatively large, or the situation that pump 10 liquor charging temperature is higher, outlet pipe slip joint 50 can effectively extraction duct expand with heat and contract with cold and the length change produced, and isolating pipelines system is on the impact of pump 10.
Each technical characteristics of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristics in above-described embodiment is not all described, but, as long as the combination of these technical characteristicss does not exist contradiction, be all considered to be the scope that this specification is recorded.
