The role of hydraulic wrench in plate replacement, installation and maintenance
source:Industry News release time:2021-12-11 Article author:Rosit Popular:Air band saw
1. In the production of plate heat exchangers, a hydraulic wrench is an indispensable tool. It is simple to use, saves effort, does not require a lot of operating space, greatly reduces the labor intensity of workers, and improves production efficiency. , And to ensure the quality of the product, in the process of pressing the splint and the stainless steel plate, all the plates are advanced in parallel at the same time, which ensures the tightness of the plate change.
2. For a hydraulic wrench to replace a plate, whether it is newly installed or disassembled for maintenance and reinstallation, how the hydraulic wrench can ensure that all plates and splints are well squeezed together is a problem that must be taken seriously in operation. The tightening process of Bo Ting's hydraulic wrench is as follows: Assume that there are eight tightening screws for the installation equipment, and after all the accessories are basically assembled, insert the quick connector of the hydraulic wrench between the wrench and the front splint, and lock it according to the regulations. , Began to suppress.
So we should use hydraulic wrench to pay attention to the following two points
1. The reaction rod should be placed in a suitable place to ensure the force
2. The wrench must be rotated within the specified range of use of the equipment). The pressure gauge must be used to know the torque during the pressing process. After the first tightening, move the reversing valve to the other side to make the pressure return to zero. Open the hydraulic connector on the plate heat exchanger. Repeat the above steps, you can use a hydraulic wrench to fasten the screws on the board, and make a qualified product.
