Heat exchangers are required in all walks of life. Now in the entire market, there are relatively many types of heat exchangers. Different types of heat exchangers have different operating principles, functional advantages, and related characteristics. For this reason, for broad users, they should choose according to their own practical needs. When using the Plate heat exchanger, you should understand the relevant precautions. In order to extend the service life of the Heat Exchanger, the heat exchanger needs to be cleaned. When cleaning, the corresponding cleaning method should be grasped to ensure the corresponding cleaning effect.
Not only that, in the daily application process, the gasket of the heat exchanger should also be replaced. Of course, when making replacements, it is important to relatively clearly understand the corresponding operating procedures and grasp the corresponding replacement methods. There are many types of gaskets for heat exchangers, including natural rubber, ethylene-propylene-diene rubber, silicone rubber, and asbestos fiberboard. With the continuous expansion of the application field of plate heat exchangers. For different media and processes, there are different requirements for temperature, pressure and corrosion resistance. To this end, you should target different situations, and then choose gaskets of different materials. Of course, the cross-sectional shape of the gasket should be the first shape is a hexagon. So what are the main replacement processes when replacing gaskets? It is a problem that many people are more concerned about.
The used gasket should be removed, and of course, the relevant precautions should be clarified during the disassembly process. There must be no scratches in the gasket groove, so it is relatively important to take corresponding protective measures during disassembly. Along with this, a clean new gasket should be attached to the board, and the gasket groove and gasket should be scrubbed and cleaned with a clean cloth or cotton yarn. Of course, the sheet pasted with the gasket should be laid flat, and in a cool and ventilated place, it should be dried before being used. Apply the adhesive in the gasket groove, and it should be applied evenly at this time. In the process of using the heat exchanger, leakage, fracture, aging and other phenomena usually appear. At this time, it should be replaced in time. In short, in the daily operation process, the heat exchanger should be repaired in time. If there is a fault in the gasket, it should be replaced in time.
Heating, bathing, and air-conditioning systems in residences, institutions, factories, mines, hospitals, schools, etc. all need to be applied to heat exchange units. The main composition of this unit is composed of heat exchanger, circulation pump, make-up pump, electric control cabinet, base, pipeline, valve and appearance, etc., and can be equipped with automatic constant-pressure make-up water supply equipment and water treatment according to user needs Equipment, water pump frequency conversion control, etc., then constitute a complete heat exchange station. This type of unit mainly uses a standardized and modular design, with complete equipment, convenient equipment, and high efficiency and energy saving. Because of this, it is widely used in residential district heating, central air conditioning and other systems.
Before using the unit, the unit should be equipped. What are the relevant equipment requirements? Is the first consideration. The hoisting technical requirements are mainly manifested in that for the hoisting part, all rigging should be prepared, and in accordance with the usual rules, they should be careful and review the mission. For larger units, because the corresponding diameter is larger, there are more heat exchange tubes together, and the corresponding lifting weight is large, so the lifting quality is very large. Therefore, when lifting and binding, it should be selected on the housing support. Reinforcement pads, and wooden blocks at both ends of the shell are used to maintain the shell. The primary effect is to prevent the shell from being pinched by the wire rope when it is hoisted, and then plastic deformation and damage occur.
In terms of unit equipment standard tendency, there are also certain requirements. The tendency of each part of the unit standard should meet the requirements of the specification. The requirements of the support equipment are mainly as follows: a movable support on the root, a slide plate should be embedded on one side, and anchors on both ends of the anchor bolts. Before leveling the equipment, the oblique horn should be welded firmly to the base plate of the unit. Of course, the horn should be lubricated and level to ensure the free elasticity of the movable support.
In addition to clarifying the relevant equipment requirements, you should also understand the characteristics of the heat exchange unit. The first manifestation is that the unit structure is relatively compact. Therefore, in the daily operation process, the stability is relatively strong, the safety factor is relatively high, and the operation is relatively convenient. In the process of practical communication, the unit can completely process according to its own actual situation. The unit first selects the intelligent redemption method, so the entire water temperature must be set according to relevant procedures. With outdoor temperature changes, it becomes different.
