Abstract
A lubricating system configured to provide a lubricating oil from a lubricant reservoir to a fluid end by use of a pump. The lubricating system has a plurality of check valves that each have an elastomeric insert. The lubricating system also has at least one pressure relief valve that is configured to re-rout lubricant to the lubricant reservoir when needed to stabilize pressure within the system. The lubricating system uses a pump drive controller and at least one sensor to selectively turn the pump on and off.
Claims19
A lubrication system, comprising:
- a lubricant reservoir configured to contain a lubricating medium;
- a first pump connected to the lubricant reservoir, the first pump containing a plurality of reciprocating lubricant plungers each configured to move the lubricating medium through the lubricating system;
- a fluid end of a separate second pump, the fluid end comprising at least one reciprocating fluid end plunger;
- a plurality of check valves interconnecting the first pump and the fluid end;
- at least one first conduit interconnecting the plurality of check valves and the first pump;
- at least one pressure relief valve;
- a second conduit interconnecting the at least one pressure relief valve and the lubricant reservoir;
- and
- a relief manifold;
- in which the plurality of check valves and the at least one pressure relief valve are attached to the relief manifold.
A lubrication system, comprising:
- a lubricant reservoir configured to contain a lubricating medium;
- a first pump configured to pressurize the lubricating medium, the first pump comprising at least one reciprocating plunger;
- a pump drive connected to the first pump;
- a sensor configured to measure a physical characteristic and provide an output;
- a pump drive controller configured to selectively turn the pump drive on and off based on the output received from the sensor;
- a plurality of check valves, each check valve comprising an elastomeric insert;
- at least one first conduit interconnecting the first pump and the plurality of check valves;
- at least one pressure relief valve;
- a second conduit interconnecting the lubricant reservoir and the at least one pressure relief valve;
- and
- a relief manifold, in which the plurality of check valves and the at least one pressure relief valve are attached to the relief manifold;
- in which the lubricant reservoir is configured to transmit the lubricating medium from the lubricant reservoir to a fluid end of a second pump through the plurality of check valves.
