脱硫泵注意事项
Precautions for desulfurization pump
1、轴承组件装配:将两个角接触球轴承背对背装在轴承盒内,并装在靠紧泵联轴器轴端的轴肩,在轴另一端依次装入挡油盘、圆柱滚子轴承,两端用圆螺母紧固好轴承,将轴传入轴承体内,分别上好轴承盒与轴承压盖,套上防尘盘,挡水圈、圆螺母、轴套、并安装托架上。
1. Bearing assembly: install the two angular contact ball bearings back to back in the bearing box, and install them on the shoulder close to the shaft end of the pump coupling. Install the oil baffle and cylindrical roller bearing at the other end of the shaft in turn. Fasten the bearings with round nuts at both ends, put the shaft into the bearing body, separate the bearing box and the bearing gland, put on the dust disk, water baffle, round nut and shaft sleeve, and install them On the bracket.
2、填料轴封组件的装配:填料轴封组件包括填料箱,轴套、填料环、填料及填料压盖等零件组成。填料选用耐磨、耐蚀的碳素纤维填料。
2. Assembly of packing shaft seal assembly: the packing shaft seal assembly consists of packing box, shaft sleeve, packing ring, packing, packing gland and other parts. Wear resistant and corrosion-resistant carbon fiber packing is selected.
3、泵头部分组装:将后泵壳紧固的托架上,并在后泵壳内装入填料箱,在轴上装好键、"O"型圈、装副叶轮(或叶轮挡圈),将后护板装后泵壳上案后将叶轮紧固在轴上,以此在后护板套上"O"圈套、涡壳,在前护板套上"O"圈套,并装在涡壳上,最后将前泵壳与泵壳合装。拧紧螺栓。注意装配时应将轴套、副叶轮与叶轮、填料箱与护板、涡壳、前护板之间密封的"O"圈套放置在正确并压紧。
3. Assembly of pump head: install the bracket fastened to the rear pump casing into the stuffing box in the rear pump casing, install the key, O-ring and auxiliary impeller (or impeller retaining ring) on the shaft, and fasten the impeller on the shaft after the rear guard board is installed on the pump casing, so as to install the O-ring and volute on the rear guard board, O-ring on the front guard board and volute, and finally assemble the front pump casing and pump casing. Tighten the bolts. Pay attention to place the "O" ring between the shaft sleeve, the auxiliary impeller and the impeller, the stuffing box and the guard board, the volute and the front guard board correctly and tightly.
