Description of safety valve overpressure overflow indication

The distributor is equipped with a safety valve, any one of the distributor supply ports, if the load pressure is higher than the set pressure of the safety valve (factory setting is according to customer requirements), the safety valve will automatically open the oil return channel to concentrate the pressure oil back to the pump In the body, the overpressure overflow indicator rod is extended to display for observation distinguishing the overload of the lubrication part (lubrication point). The other oil outlets of the distributor can still maintain normal oil output; when the load of the lubrication part is less than the starting pressure of the safety valve , The safety valve can close the oil return channel by itself, that is, resume normal oil supply.

WDBF progressive distributor

piece type combination structure, choose different pieces according to different oil demand of lubrication point, combine according to needs

can be connected in series with the son-in-mother type, two-stage three-stage oil separation

Each oil port is equipped with a safety valve, overflow grease directly overflows the overflow port

Designed specifically for mining machine conditions

The principle of safety valve is the same as WDGF
