Tips for installing steam traps
The basic function of the steam trap is to expel the condensate, air and carbon dioxide gas in the steam system as quickly as possible; at the same time, to minimize the automatic leakage of steam. What are the specific requirements for the function, energy saving measures, operation, maintenance management and other aspects of the trap? Do not leak steam when condensed water is removed. Eliminating condensation from time to time does not leak steam is the most basic condition of the trap. Therefore, although it is a condensate device that excludes the separation from steam, it is not called a condensate trap, but is called a steam trap. The operation of the trap is accurate and sensitive, which means that the condensate is opened and closed. That is, when the condensed water is removed, the trap is fully opened and discharged quickly; at the end of the discharge, it can be quickly closed to prevent valuable steam from leaking. This is the main performance of the trap. That is to say, the trap has only two conditions: full opening and full closing. If the switching action is slow, the switch is not in place, which will cause the throttling effect, which is easy to cause the overall damage of the trap, and is also the main cause of leakage steam. As mentioned above, the action of the trap is in principle fully open or fully closed, ie open and closed. Depending on the type, there may be two types of continuous discharge and intermittent discharge. It is possible to exclude all condensate from anywhere in the steam system. The trap must be equipped with piping, heat exchangers, etc., which are capable of high-crossing and accurate elimination of steam-using equipment, and condensate from any part of the steam system. It can discharge air and condensate at the same time. The air that is mixed into the steam plant is initially mixed in the steam and is separated when the steam is formed into water. It forms an air layer on the heat transfer surface of the steam-using equipment, which seriously affects heat transfer, so air must be excluded. Applicable pressure range is large. For a trap, if the pressure is slightly changed, its performance is affected, and even stopping the action is not possible. In this case, its performance is not affected and can be adapted to any pressure. At the same time, the back pressure of the trap is required to be large. Easy to access and maintain. This requirement is related to the structure of the trap. The trap is required to have a simple structure and few moving parts. In order to make the valve's moving parts not stress, the appropriate material should be selected, and more importantly, the structure should be easy to process. In short, steam traps should be managed without the need for regular maintenance, which means less maintenance costs. High practicality. The trap should be small in size, light in weight, high in life, low in price, and free from the ability to drain due to air or steam obstacles, and cause air blockage and steam locks.
