What should be paid attention to when using the plate heat exchanger hydraulic wrench:

1. Friction of the hydraulic wrench of the plate heat exchanger is a common phenomenon, which one to choose for the hydraulic wrench of the plate heat exchanger, but it also has both good and bad effects. The good aspect is to keep the parts together; the bad aspect is that when tightening, the brand of the plate heat exchanger hydraulic wrench may bring wrong results. A mechanic uses only 10%-20% of the force to tighten the joint by hand. In many cases, 40%-50% of the torque is used to overcome the friction between the bolt head and the part. The mating thread surface of the screw hole also generates additional friction. So when tightening bolts, all these friction factors and other factors should be taken into consideration.

2. When tightening the nut or bolt with damage or obstruction on the thread of the plate heat exchanger hydraulic wrench, pay attention to how much additional torque is needed to pass the damaged part, and add this additional torque to the recommended torque value.

Usage

Connect the high-pressure outlet (A) of the pump with the high-pressure inlet (H) of the hydraulic wrench, and the low-pressure outlet (B) of the pump and the low-pressure inlet (R) of the hydraulic wrench with high-pressure tubing respectively. When connecting, the quick connector on the oil pipe should be inserted to the end, and then tighten the fixing nut by hand. Check carefully whether the oil pipe joints are connected reliably and whether there is oil in the pump. Insert the power plug of the pump into the power source (220v50Hz). It is strictly prohibited to run without oil! Press the wire control switch button with one hand. Do not release the button before the pressure value reaches the set value. At the same time, slowly rotate the pressure regulating valve clockwise with the other hand. When the pressure gauge pointer reaches the preset pressure value, Lock the pressure regulator, and then release the remote switch button.
