How to maintain and repair the pressure reducing valve and flow control valve of hydraulic wrench?
source:Industry News release time:2021-04-08 Article author:Rosit Popular:Air band saw
The hydraulic wrench is a tool that is often used in the maintenance and installation of enterprises under current working conditions. It has successfully become a necessary tool for industrial production with the advantage of "four or two shifts". So what should be paid attention to in the usual maintenance and maintenance of the pressure reducing valve and flow control valve in some common hydraulic wrenches?
The reason for the failure of the hydraulic wrench pressure reducing valve may be that the pressure is too high or lower than the relief valve. It may also be due to pressure instability. These failures may cause the spool movement to be inconsistent, or the poppet valve may not be stable, or may cause air to be mixed in the oil. In response to these, we can open the small hole in the center of the back pressure variation spool of the oil discharge to check the amount of oil inside. Then separate the tubing from the other control valves and open it to shoot out the air inside. One thing that needs special attention here is the hydraulic control valve.
The failure of the hydraulic wrench flow control valve may cause the pressure compensation device to not work. This may be caused by dust in the valve core or dust in the small holes in the sleeve. In this case, it is only necessary to decompose and clean at the outlet pressure difference of the flow.
The adjustment shaft of the hydraulic wrench flow rate turns tight. The cause of this situation may be due to dust on the adjustment shaft. It takes a lot of effort to clean up here, and it is impossible to clean up the roots of ordinary utensils. We can take the way of measuring in, let him start the scale below 6 o'clock when the pressure rises for the second time, and clear up the pressure once.
In addition to these, hydraulic wrenches should also pay attention to the maintenance and repair of the directional control valve. During manual operation, it was found that the oil seal of the valve stem was leaking, which may be caused by the damage of the oil seal. In this case, just open the cylinder head and replace the oil seal.
The above is the maintenance and repair of various valve parts in the hydraulic wrench. As long as the above maintenance and maintenance are done, the hydraulic torque wrench of DOUHEN company guarantees a life of up to 8-10 years.
