板式换热器换热功能
板片的功能,在水—水换热、逆流运转、热侧定性温差为40℃、两边流速为0.5m/s条件下的总传热系数,对水平平直波板片,应大于2210W/(m2.K);关于人字形波纹板片,应大于2908W/(m2.K)。
液压实验
以水为实验液体,两边应别离进行单侧压力实验,实验压力为1.25倍规划压力。试压后应扫除积水,吹干或晒干,然后再夹紧。
垫片质量
a.运用温度和物理功能应契合相关规定。
b.外表不允许有面积大于3mm2、深度大于1.5mm的气泡、凹坑及其它影响密封功能的缺点。

Heat transfer functionBoard piece of functionality, in water - water heat exchanger, countercurrent operation, on both sides of the hot side qualitative difference in temperature of 40 ℃, the velocity of 0.5 m/s under the condition of total heat transfer coefficient, the horizontal flat wave plate, should be greater than 2210 w/(m2. K);About herringbone corrugated plate, should be greater than 2908 w/(m2. K).The hydraulic experimentExperimental liquid in water, both sides should be one sided pressure separation experiment, the experimental pressure of 1.25 times planning.After pressure testing should be clear water, dry or dry, then the clamping.The quality of gasketA. use temperature and physical function should agree with related regulations.B. there is no bigger than 3 was appearance, depth is greater than 1.5 mm of bubbles, pits and other faults affect the sealing function.
