The pump cover and suction pipe are made into one body, which locate horizontally, the outlet could rotate 90 degree, 180 degree, 270 degree if required. Pump connected with the electric motor directly by gear-inset type shaft coupling. See from the driving direction the pump shaft rotate clockwise. Sealing ring is made of cast iron, which prevent the high-pressure water in the water pump from leaking back entering water position, it could be changed for spare parts after wear and tear.JQ型胶球输送泵主要零件有泵体、泵盖、轴承箱（或托架）、叶轮、轴等，泵体叶轮和泵轴均采用耐海水的不钢材质316L制成。泵盖与吸入管铸为一体，呈水平方向，出水口根据需要可旋转90度、180度、270度。泵与电机用牙嵌式联轴器直接连接。从传动方向看时，泵轴为顺时针方向旋转。密封环为铸铁制成，防止水泵中高压水漏回进水部位，磨损后可用备件更换。3 Notice Items注意事项a. Entry/exit pipeline should not bent rapidly avoid of being clog.进出管路不应急剧弯转，以防堵塞。b. Check consumable parts and bearing timely according to actual status, which must be changed and avoid of accident if required.根据使用情况，定期检查易损件和轴承，必要时进行更换以防事故。c. In winter, the water must be discharged completely during the pump stop working period avoid freezing crackles.冬季停泵时应将水放净，以防冻裂。d. Adjustment it in the range of this pump technical specification in order to be used in economic and durable. 调整应在该泵的技术规范内使用，以达经济耐用。4 Faults and Solutions故障和排除FAULT故障REASON原因SOLUTION处理轴功率过大power of the shaft isoverloadfrictions in pump泵内产生摩擦disconnect and inspect and resolve frictions拆检解决摩擦扬程不够Lift is not enoughImpeller damaged badly叶轮磨损严重Change a new impeller换新叶轮轴承过热Shaft overheatLack of lubricant or impurities got into bearing缺乏润滑油或轴承进入杂质clean and fill with lubricant and change a new one清洗加油换新轴承发生震动Happening vibrationBearing has been damaged, impeller lost balance after been damaged, a great deal of air get into pump轴承已损坏，叶轮磨损后失去平衡，泵进入大量气体Change a new bearing and adjust the balance or change a new impeller and check it if the pipeline air-leak 换新轴承重找平衡或换新叶轮检查管路是否漏气5 Installation and maintenance安装与维护In order to prevent the turbine in operation from major damage due to the Before installation, inspect pump and accessories and prepare for instruments. Observe it if the base of the foundation is firm. The correct position of the pump shafts and electric motor should be adjusted and found, it must be ensured shaft coupling is aligned with the other one without deviation and with suitable gap. The pipe of inlet is supported on its own bracket, in event of avoid putting its weight on the pump. It should be inspected the driving direction of the pump before operation. When it begin to start up it must be exhausted and to be vacuum if it doesnt pour into the head of water. When its running it must be adjusted degree of tightness of the stuffing, it is suitable that it is 10-20 drops of water every minute from the stuffing.安装前作好泵与附件的检查和工具准备工作。注意底座基础牢固可靠。调整找正泵轴、电机轴的位置，保证两联轴器中心对准，不得偏差，并保证适量间隙。输入水管应由它自己的支架支撑，以免将重量压挂在泵上。运转前检查泵的转向。启动时，如不是灌注水头，必须设法抽真空。运转时对填料的松紧程度进行调整，以每分钟从填料中渗透10-20滴水为宜。In order to watching the running conditions of the pump, it should be installed the pressure-meter (or vacuum-meter) on the inlet of the water pump and installed the pressure-meter on the outlet of the water pump. During its running period, the increasing temperature of the bearing is not above 35 degree, its top temperature is not above 75 degree. It must have an inspection of the pump timely every 1000 working-times. The maximum diameter of the cooperation position gap between impeller and sealing ring is 1mm, the sealing ring can be changed if the number is above 1mm. If the water pump stopped to work for a long period, we should disconnect and inspect its parts and store them properly with coated oil avoiding corrosion.水泵进口应按压力表（或真空表），出口按压力表，以监视泵的运转情况。水泵在运转过程中，轴承温升不应超过35，其最高温度不应大于75。水泵每工作1000小时，应进行周期检查。叶轮与密封环配合处的间隙在直径上最大值为1毫米，若超过，可换密封环。若水泵长期停用，应对零件拆卸检查，涂防锈油妥善保存。Procedure of installation and maintenance of the water pump is carried out according to the following order (refer to the structure drawing), loosen and replace the hexagon nuts, remove the inhalant oviduct, loosen and replace the impeller nut, remove the holding back gasket, impeller, the body of pump, rear cover and sleeve, loosen and replace the hexagon nut, replace the bearing cover, using iron duct which diameter is a bit bigger than shafts knocking the bearing inner ring gently on rear position and remove the shaft. When installation, carry it out according to the counter-order.对水泵进行维修保养时，可按以下顺序，并参照结构图，拧下六角螺母，取下吸入喇叭管，拧下叶轮螺母，取下止退垫圈、叶轮、泵体、后盖和防护套、拧下六角螺钉，拆下轴承压盖，用略大于轴径的铁管从后端轻击轴承内圈，取下轴。安装时反顺序进行。JQ type rubber cleaning pump structure drawing (1)JQ型胶球清洗泵结构图（一）(125JQ-15) 1.inhalant oviduct吸入喇叭2.sealing ring密封环 3.impeller nut叶轮螺母 4.pump body泵体5.sleeve轴套6.stuffing cover填料压盖7.bearing cover轴承压盖8.bearing轴承9.bracket托架10.shaft轴11.shaft connection联轴器12.rear cover后盖13.impeller叶轮14.disembogue water ring放水圈JQ Type Pump outline drawing and outline dimension JQ型外形图及外形尺寸（一）(125JQ-15)JQ type pump dimension of outline and i
