5. The motor is not running in the right direction, the motor phase failure speed is very slow. Adjust the direction of the motor and strengthen the motor wiring. 6. Pipeline resistance is too large, centrifugal pump selection is improper. Reduce pipe bends and re-select pumps. Two. The reason and solution of insufficient flow of hot water circulating pump 1. Hot water circulating pump import and export valve is not open, inbound and outbound pipe obstruction, miscarriage impeller obstruction. Solution to remove the blockage.

Smooth operation, long life. 4. Build pumping stations according to the selected pumps, with less investment in the project and low operating costs. Hot water Circulating pump is a new generation of energy-saving and environmental protection pipeline pump based on the research and development of ISG,ISW type pipeline centrifugal pump. Hot water Circulating pump perbance is excellent, high reliability, long life, reasonable structure, beautiful appearance, with industry-leading level. IRG (GRG) type vertical hot water (high temperature) circulating pump, ISWR horizontal hot water circulating pump is widely used in: energy, bllurgy, chemical, textile, paper. Without cavitation of the pump, this can not only reduce the excavation depth of the pumping Room 3. Has good anti-cavitation perbance and hob and other boilers high temperature hot water pressurized circulating conveyor and the city using warm system circulating pump, IRG type use temperature T<120℃,GRG type use temperature T<240℃, The ISWR type uses a temperature T≤120℃.

三、管道泵工作条件:
1、吸入压力≤1． 0MPa，或泵系统工作压力≤1．6MPa，即泵吸入口压力+泵扬程≤1．6MPa，泵静压试验压力为2．5MPa，订货时请注明系统工作压力。泵系统工作压力大于1．6MPa时应在订货时另行提出，以便在制造时泵的过流部分和联接部分采用铸钢材料。 
2、环境温度<40℃，相对湿度<95％。
3、所输送介质中固体颗粒体积含量不超过单位体积的0．1％，粒度<0．2mm。

注：如使用介质为带有细小颗粒，请在订货时说明，以便厂家采用耐磨式机械密封。

四、管道泵产品特点:

1、管道泵为立式结构，进出口口径相同，且位于同一中心线上，可象阀门一样安装于管路之中，外形紧凑美观，占地面积小，建筑投入低，如加上防护罩则可置于户外使用。
2、叶轮直接安装在电机的加长轴上，轴向尺寸短，结构紧凑，泵与电机轴承配置合理，能有效地平衡泵运转产生的径向和轴向负荷，从而保证了泵的运行平稳，振动小、噪音低。
