      Plate heat exchangers are widely used in life and production due to their sturdy and durable work efficiency. Each type of heat exchanger has its irreplaceable role. The plate heat exchanger is mainly composed of heat transfer plates and gaskets. It consists of two end plates, a fixed head, a movable head (head cover), clamping bolts, brackets, and inlet and outlet pipes.

      A dedicated hydraulic wrench is essential for plate heat exchangers, telling you why you must use a dedicated hydraulic wrench.

      For a brand new plate heat exchanger, it is necessary to tighten the screws to be installed, and the damaged plate heat exchanger needs to be disassembled for secondary installation during maintenance. The good fixing effect largely determines the efficiency of the machine. The use of a dedicated hydraulic wrench allows the plates and splints in the machine to be pressed together.

      General professional operators carry special hydraulic wrenches for installation and maintenance work. In the process of locking, it must be operated in strict accordance with the provisions in the product manual. In the process of pressing, we must pay attention to two key points. In order to ensure that the machine is evenly stressed, place its reaction rod at the specified position. Be sure to do so within the specified range of use when turning the wrench to twist the lever. Moreover, the pressure gauge should be observed at any time during operation to know the magnitude of the torque. When the first tightening operation is completed, the pressure is reset to zero, and the reversing valve is pulled in the direction to perform secondary tightening.
