To reduce resistance from the suction section of pump, the water pump must be installed at the condenser inlet of air conditioner.
为减小泵的吸入段阻力，水泵必须装在空调机冷凝器进口。
2
Add the resistance in the outlet to lower the capacity. Check the resistance in the suction pipe of pump. Check the bottom valve and lower the high of suction position.
增加出水管阻力以减低流量，检查泵吸水管内阻力，检查底阀减小吸水高度。
3
Owing to its strong water suction, the resistance of the material would widely drop after wetted, the dimension of which inflated and deformed comparatively.
