150HW-8S (6HBC-35) daily maintenance of common flow pump:
1 ）轴承采用稀油润滑时,应该经常检查和控制轴承体的游标杆两根标线间：轴承采用润滑脂润滑时，应定时补充油量。 ( 1 ) When the bearing is lubricated with thin oil , the two marking lines of the vernier rod of the bearing body should be frequently checked and controlled: when the bearing is lubricated with grease, the oil amount should be regularly replenished. 型泵拆去前盖和后盖来补充，对400-650HW型泵可通过油杯来补充。 For the 100-350HW type pump, remove the front cover and the rear cover to supplement it. For the 400-650HW type pump, it can be supplemented by the oil cup.
）经常检查轴承的升温。 ( 2 ) Check the bearing temperature frequently. ° C ，最高温度不得80 ° C 。 Generally it should not be higher than the ambient temperature of 40 ° C , and the maximum temperature should not be 80 ° C.
）注意泵运转时有无摩擦和撞击声。 ( 3 ) Pay attention to whether there is friction and impact sound when the pump is running. If the pump cover and the impeller are rubbing, add a paper pad between the pump cover and the pump body. 毫米。 The actual use gap is 0.3-0.7 mm.
）填料的调整必须适当，液体应从填料压盖处成滴状间断漏出。 ( 4 ) The adjustment of the packing must be proper, and the liquid should leak intermittently from the packing gland. The packing is too tight, the shaft will generate heat and increase power, the packing is too loose, too much liquid leaks, and the efficiency is reduced.
）如电机与泵直联，两轴的轴心线应在一条直线上。 ( 5 ) If the motor and the pump are directly connected, the axis of the two axes should be on a straight line.
）检查进水管路有无漏气现象。 ( 6 ) Check for air leakage in the water inlet pipe.
）注意功率是否突然的增大和降低，流量是否突然的减少，如有，应该停车排除。 ( 7 ) Pay attention to whether the power suddenly increases and decreases, and whether the flow rate decreases suddenly. If so, stop and remove it.
）经常检查各螺栓是否因震动而松动。 ( 8 ) Frequently check whether each bolt is loose due to vibration.
）在冬季，停车后应将泵和管路的内存水放掉。 ( 9 ) In winter, the water in the pump and pipeline should be drained after stopping.
）泵在初期使用时200小时或半年后，因更换润滑油（脂）。 ( 10 ) The pump is replaced for lubricating oil (grease) after 200 hours or half a year during initial use. 小时或一年后换油一次。 Change the oil every 1,000 hours or one year later.
）泵工作3000小时或三年后，应该进行解体检查和保养。 ( 11 ) After 3000 hours or three years of pump operation, disassembly inspection and maintenance should be performed.
）对于长期停用的泵，应该将运行部分拆下，做防锈的处理后妥善保管。 ( 12 ) For long-term inactive pumps, the operating part should be removed and stored in a safe place after antirust treatment.
