Five production processes of plate heat exchanger rubber gasket_
1044 Plate heat exchanger rubber gasket manufacturing process, under normal circumstances, the plate heat exchanger rubber gasket manufacturing process includes five process steps. ①The mixing link of the rubber compound is to mix various raw and auxiliary materials according to the requirements of the formula. ②Form the rubber blank link, that is, the rubber material is manufactured into rubber strips through the extruder equipment. ③In the compression molding process, the unvulcanized rubber strip is placed in the cavity of the hot mold, the mold is closed for vulcanization, and the rubber sealing gasket is formed in the press equipment. ④ Post-vulcanization, that is, put the molded and vulcanized gasket in an oven under static conditions to complete vulcanization. ⑤ Finished product inspection, that is, part of the finished product is selected for finished product inspection according to the process standard. Plate heat exchanger rubber gaskets and plate heat exchanger sealing gaskets are very critical components of detachable plate heat exchangers. The application range of plate heat exchangers is also largely limited by the sealing gaskets. The requirements for sealing gaskets in the medium are very high. As an important component, the gasket of the plate heat exchanger has an important impact on the service life of the plate heat exchanger. If these gaskets are hardened and lose their due elasticity, the heat exchanger may not operate normally. , Because the gasket must not only seal the medium so that it does not leak to the external environment, but also prevent the mutual mixing between the heat exchange media. Therefore, the gasket is considered to be important and needs to be carried out in the plate converter. Demanding parts. Plate heat exchanger rubber pad flow form: unilateral flow/diagonal flow plate heat exchanger plates are divided into unilateral flow and diagonal flow according to the flow form of the heat exchange medium. Correspondingly, the plate heat exchanger is sealed According to the flow form of the heat exchange medium, the gasket is divided into two types: unilateral flow and diagonal flow. Unilateral flow means that the heat exchange medium flowing in from the right corner hole of the heat exchange plate flows out from the right corner hole. Similarly, the heat exchange medium flowing in from the left corner hole flows out from the left corner hole. Diagonal flow means that the heat exchange fluid flows from the right corner hole and then flows out from the left corner hole, or the fluid flowing in from the left corner hole flows out from the right corner hole, showing a diagonal flow pattern. In terms of heat exchange efficiency, the diagonal flow method is better than the unilateral flow method, but the cost of the unilateral flow method is relatively low, so when the heat exchange efficiency can be met, the unilateral flow method is generally adopted.
