板式换热器的维护保养注意事项?

  板式换热器是流程工业设备中热交换技术中一个重要部件。在各个板式散热片之间进行密封的弹性密封垫是一种易损件,并且在自然条件下也是一种易于老化的零件。它的使用寿命对于板式换热器的使用寿命有着重要的影响。如果这些密封热硬化了,失去了原有的弹性,则可导致换热器无法正常工作。 下列因素对弹性密封垫的使用寿命有着重要影响:

  1、换热器的工作方式(连续的还是不连续的);

  2、散热的介质和使用的清洁剂的腐蚀性;

  3、工作温度;

  4、工作压力;

  5、由于过大的压力和不均衡的压力而使弹性密封垫的应力较大;

  6、自然老化。 弹性密封垫的软化与压力和温度有关,当密封垫失去弹性后,换热器会出现滴漏。

Matters needing attention in the maintenance of plate heat exchangers?

Plate heat exchanger is an important part of heat exchange technology in process industry equipment. The elastic gasket sealed between various plate radiators is a kind of vulnerable part, and it is also a kind of part which is easy to aging under natural conditions. Its service life has an important influence on the service life of the plate heat exchanger. If these seals harden and lose their original elasticity, the heat exchanger will not work properly. The following factors have an important effect on the service life of the elastic gasket.

1, the working mode of heat exchanger (continuous or discontinuous);

2, the heat dissipating medium and the corrosiveness of the cleaning agent used.

3, working temperature;

4, work pressure;

5, due to excessive pressure and uneven pressure, the stress of the elastic gasket is larger.

6, natural aging. The softening of elastic gasket is related to pressure and temperature. When the gasket loses elasticity, the heat exchanger will leak.
