  拆卸三柱塞往复泵时，在清水离心泵已停车的情况下，应通知化工泵操作人员切断化工介质，进行必要的工艺处理，落实各项安全措施后，可按下述步骤进行。 ①拆下联轴器罩，断开泵和减速箱、减速箱和电动机的联轴器。 ②拆除齿轮油泵、所有油管线及泵进出口管道。 ③拆除罩壳。 ④拆除十字头法兰，使十字头与柱塞分开，取出球面垫。 ⑤拆除十字头压板，冲出十字头销，要仔细拆卸，切莫将机件碰坏。 ⑥盘动曲轴，使连杆和十字头分开，取出十字头；将连杆大头盘到上方，测量连杆螺栓长度，并作记录；松掉连杆螺栓的螺母，抽出连杆螺栓，再测量连杆螺栓长度，记录两次测量结果，比较螺母上紧后螺栓长度的绝对伸长值，从而使螺栓紧力有度；取出连杆，将连杆大头轴瓦及小头衬套取下；吊出曲轴，拆除曲轴两端轴承。 ⑦松开调节螺母，抽出柱塞；取出填料、填料套、导向套。 ⑧拆除缸盖螺栓，拆下缸盖；取出上垫圈、上缸套、中垫圈、出口单向阀；取出下缸套、下垫圈、进口单向阀。 在拆卸过程中，对拆下的零件要不磕不碰不落地，做好标记，摆放有序。拆卸完毕一后，应及时清洗，并按零件质量标准仔细检查，以便决定修复或更换新的备件。

Horizontal three piston pump disassembly Remove three plunger reciprocating pump, the water pump has been parking in the case of the operator shall notify the chemical pump cut off chemical medium, the necessary treatment process, and implement security measures, according to the following steps. ① Remove the coupling cover, disconnect the pump and gear box, gear box and motor coupling. ② Remove the gear pump, pump all the oil pipelines and export pipelines. ③ Remove casing. ④ Remove the flange crosshead, crosshead and plunger to separate out spherical pad. ⑤ Remove the crosshead plate, out of the crosshead pin, carefully remove and must not be mechanical break something. ⑥ plate moving crankshaft, connecting rod and crosshead to separate, remove the crosshead; the connecting rod to the top of the plate, measure the length of connecting rod bolts, and for the record; loose connecting rod bolt nuts, connecting rod bolt out, and then measuring connecting rod bolt length, record the results of two measurements, comparing the length of the bolt after tightening the nut on the absolute value of elongation, so that the bolt tightening force with degrees; remove the rod, the connecting rod bearing and bushing head off; hanging the crankshaft, remove the crankshaft bearings at both ends. ⑦ Loosen the adjustment nut, out of the plunger; remove the filler, filler sets, guide sleeve. ⑧ Remove cylinder head bolts, remove the cylinder head; out of the washer, on the cylinder, the washer, the export-way valve; out under the cylinder, under the washer, the import-way valve. In the demolition process, the removed parts do not touch either knock off the ground, marked, placed orderly. After completion of a demolition, should be cleaned, according to double-check part quality standards to determine repair or replacement of spare parts.
