Compaction of plate heat exchanger
The compression interval between the heat exchanger plates of the plate heat exchanger is determined by referring to the thickness of the heat exchanger plates and the heat exchanger gaskets, and each model has a corresponding size standard. And whether it is during use or during normal maintenance work, you should check whether the pressed bolts are firm and tight. Although it will not cause vibration and other movements to cause the bolts to loosen, the related inspections are still relevant after long-term use. Very necessary. In addition, sometimes the cleaning work is done. After the completion of the resetting of the bolts, is there any tightening? Is there any diagonal? Cause plate variation. Of course, the pressing distance between the plates is an important point to prevent water leakage.
When reinstalling the heat exchanger plates of the plate heat exchanger, pay attention to tightening the heat exchanger plates. If there is a need to superimpose the heat exchanger plates, you should observe whether it leads to fixed and movable heat exchange. The shape of the heat exchanger plates has changed, and the bolts should be adjusted and increased with the installation of the heat exchanger plates. Pay attention to that if the elasticity of the heat exchanger plate is damaged beyond the limit, the performance of the heat exchanger gasket will also be declared invalid, resulting in liquid mixing or overflow, which will cause the plate heat exchanger to fail to benign used.
The long-term placement of plate heat exchangers should also pay attention to the degree of bolt tightening. The first step before installation is to tighten diagonally, and check the distance between the plates to ensure parallelism.
Another component of the plate heat exchanger is the pressure plate. The function is to tighten and consolidate the pressure plates of the heat exchanger, which can effectively prevent the heat exchanger plates from collapsing under the impact of the pressure from the liquid. In view of the design The strength of the pressure generated by the liquid is not small, and the pressure plate of the heat exchanger has a certain thickness. The between is made of nut steel for stability. In addition to the thickness of the plate heat exchanger, the splint has the length and width. The length is set according to the structure and the plate of the heat exchanger.
The tightener of the plate heat exchanger can reduce the manpower output and improve the efficiency of disassembly and installation. The clamp itself is also lightweight, small in size, easy to transport, easy to operate and easy to use. There are electric single-acting, manual single-acting and electric double-acting.
