Actually, many people have asked editor Kang Jinghui about the installation of plate heat exchanger units. So today we will go into detail about the methods for installing plate heat exchanger units, the installation steps, and what precautions should be taken during installation Firstly, a heat exchange unit consists of a plate heat exchanger, filters, valves, frequency converters, distribution boxes, a range of control systems, as well as various instruments, all connected together through pipes. For those who are not familiar with heat exchange units, editor Kang Jinghui has prepared a document that provides a comprehensive overview of all the standards related to such units; it explains in detail the various standards applicable to these devices, and it is likely to be useful after reading it. After this general introduction, let’s get to the main topic: The installation of plate heat exchange units actually takes place before they leave the factory, as they are installed on the same base as other intelligent heating devices. Proper installation of the plate heat exchange unit is a fundamental requirement for its proper operation. Editor Kang Jinghui will explain in detail the methods and procedures for installing plate heat exchange units. Installation method for plate heat exchanger units: 1. Clean the area where the equipment will be installed, and secure the heat exchanger unit using expansion bolts. 2. Before installing the heat exchange unit, concrete should be prepared in advance; the unit is then placed in position, with enough space left for subsequent maintenance work. 3. Check whether there is dust or impurities inside the pipeline; clean it thoroughly before conducting a pressure test. Once all parameter values are within the acceptable range, connect it to the heat exchange unit. 4. During the installation of plate heat exchanger units, it is essential to pay close attention to whether the primary and secondary sides, power supply design, and water supply pipes meet the required standards. 5. When there is no staff on duty, an automatic temperature control valve can be installed at the primary side inlet or outlet (for adjustment only), or a temperature sensor can be installed at the secondary side outlet. 6. The plate-type heat exchanger unit must not be installed with the equipment inverted or tilted. 7. When it is found that the unit interface differs from the pipeline, adjustments can be made to achieve a smooth connection. Installation process for plate heat exchanger units: 1. First, install the heat exchanger unit about 100 mm above the ground level and 200 mm underground, then level it off using rubber pads. 2. When preparing the concrete again, it is necessary to take into account the connections of the heat exchange unit as well as the pipes inside the machine room; leave a distance of about 1–1.5 meters around the equipment. 3. Check in advance whether there are any abnormalities with the unit. 4. Install filters and water treatment devices based on water quality analysis; the pressure reducing valve should be installed when the steam pressure is greater than 0.69 MPA. 5. The exhaust valve and safety valve can be installed within the system pipes, which is beneficial for the operation of the system. 6. After inspecting and flushing the pipes to ensure they are in good condition, connect them to the unit, in order to prevent impurities from reaching the heat exchanger. 7. Power supply (three-phase four-wire system, 380V/HZ) is delivered to the electrical control cabinet (the electrical control cabinet must be grounded), and power is applied to check for any abnormalities in the cabinet. 8. After installation, conduct a hydrostatic test on the connected pipelines and heat exchange units. 9. Users can consider insulation work for the pipes of the heat exchange unit according to their own needs. Precautions for installing plate heat exchanger units: 1. When two or more heat exchanger units are used together, a check valve should be installed in the water storage tank of each unit. 2. The heat exchange unit can be placed on an indoor concrete base and secured with anchor bolts; it is important to pay attention to the orientation of the connection pipes, as well as to considerations for future operations. A 5-meter space must be left around it for easy operation. 3. When a plate-type heat exchange unit is installed on an upper floor, it is necessary to carefully check the load-bearing capacity of the floor. 4. Ensure that all interfaces with the unit are internally clean before taking over, and conduct a hydrostatic test before operating the equipment. The above is what editor Kang Jinghui has shared regarding the methods, steps, and precautions for installing plate heat exchanger units. I hope that reading this article will be helpful to you.
