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
The bucket foundation suction penetration technique is different from the pile driving technique, and the characteristics of penetration resistance is greatly influenced by the seabed character.
桶形基础采用负压沉贯法施工,与压桩、打桩等施工方法显著不同,且阻力特性受地基性质影响很大。
3
A compression process of times compressed, high thermal efficiency. 3 no suction and discharge valves, the intake and exhaust resistance loss is almost zero.
