    • PURPOSE:To enable to simplify the sealing water system, by feeding high-temperature high-pressure fluid extracted to the outside of a pump to shaft sealing, sliding sections via a heat exchanger, and thereby making it unnecessary to inject high-pressure sealing water separately. CONSTITUTION:High-temperature, high-pressure fluid entered into a shaft sealing section 10a near a mechanical seal 11 is extracted via a passage 13a and a water extracting pipe 15a and introduced into a cooler 14, in which the fluid is cooled by cooling water passed through the inside of a cooling pipe 16. Water thus extracted and cooled is passed through a water extracting pipe 15b and a passage 13b in the pump casing 1 and then discharged to the atmospheric side B after cooling various shaft sealing, sliding sections near the mechanical seal 11 and a labyrinth 12. Thus, since it is made unnecessary to inject high-pressure sealing water especially, it is enabled to simplify the sealing water system.
    • 目的:为了简化密封水系统,通过将抽出到泵外部的高温高压流体输送到轴封,通过热交换器将滑动部分进料,从而不需要注入高压密封水 分别。 构成:进入机械密封件11附近的轴密封部分10a的高温高压流体经由通道13a和水提取管15a被抽出并被引入到冷却器14中,流体被冷却水冷却 通过冷却管16的内部。由此提取和冷却的水通过抽水管15b和泵壳1中的通道13b,然后在冷却各种轴封之后排出到大气侧B 机械密封件11和迷宫12.因此,由于不需要特别注入高压密封水,能够简化密封水系统。
