Hydraulic wrench is now life often need to use the tool, with the advantage of the 'four two dial one thousand jins' success became the vehicle maintenance and repair of the necessary tools and industrial production. So for some of the common pressure reducing valve and flow control valve of the usual maintenance and maintain and should pay attention to what? The cause of the pressure reducing valve failure may because of excessive pressure or below the overflow valve. It is also possible because of pressure instability. These failures are likely to lead to the action of valve core are inconsistent, or poppet valve is not stable, may also lead to oil in the air. According to these, we can open the discharge of oil changes in the back pressure valve core in the center of the hole, the inside of the screen. Then is separated from other control valve of the tubing to open, take out the air inside. Here, in particular, need to be aware of is the hydraulic control valve. Flow control valve failure may cause the pressure correction device does not work. This might be because the valve core with dust or the hole in the sleeve with ash, aimed at the situation as long as the flow of outlet pressure difference solution to clean. Flow adjusting shaft rotary tight. The cause of this situation might be because adjustment shaft of dust. Here, clear rise very laborious, general instruments of root cannot but may clean up there. We can take the amount into the way and let him at the time of the second pressure start at six o 'clock the scale, a high pressure decomposition to clear. In addition to these, the hydraulic spanner should also pay attention to the direction control valve maintenance and repair. While on a manually operated Industrial Valves stem oil seal leakage, this may be due to oil seal damage. This kind of situation as long as open the cylinder head, it is ok to replace oil seal.
