Instructions on the use of the electromagnetic valve electric pumps

A. in the use of the electromagnetic valve electric pumps, first of all, according to the requirement of the measurement of workpiece, selecting moderate range torque wrench, torque values measured is less than twenty percent of the torsion device in use range, should not be too great A range for small torsion part of reinforcement, small range of torsion is less can outrange that;

B. when using hydraulic flange spreader, wrench square tenon connection first good auxiliary accessories (e.g., sleeve, all kinds of batch of mouth), ensure that the connection has no problem. Before strengthening torsion, set need reinforcement force value, and lock the lock device, adjust direction switch knob to the strength of the direction, then when use fast for 5 to 6 times in a row, first make a wrench on the internal components special lubricant can sufficient lubrication, make more accurate torque wrench, durable use.
