Abstract: A lubrication system for a hydraulically operated tool has a common lubricant supply manifold that receives a lubricant from one or more lubricant reservoirs. The common lubricant supply manifold includes an inlet port through which the lubricant is received and an exit port fluidly coupled with a lubricant supply line. The system also has a primer pump connected in fluid communication with the common lubricant supply manifold, a main lubricant supply pump, and a spring check valve downstream of the main lubricant supply pump. The lubricant supply line receives lubricant from the exit port and supplies the lubricant to the main lubricant supply pump. The main lubricant supply pump increases the pressure of the lubricant and pumps the lubricant through the spring check valve and into a fluid passageway leading to the hydraulically operated tool. A detune valve is in fluid communication with a hydraulic pump providing pressurized hydraulic fluid for the tool and the main lubricant supply pump, and the detune valve is actuated by pressure in the lubricant supply line.

Abstract: Methods and systems for determining lubrication flow dispensed to lubrication points. Lubricant delivery is determined based upon the difference between volume measurements detected as the lubricant is delivered to the lubrication points, and volume measurements detected as the lubricant is vented after delivery. A flow sensor in the lubricant supply line measures lubricant delivered and lubricant vented and a controller determines the amount dispensed based upon the difference between the delivered and vented measurements.

Abstract: A lubrication control system for intermittent dosing of lubricant to one or more lubrication stations in a centrifugal separator includes a lubricant supply arrangement for supplying lubricant to at least one lubrication station. At least one pump is supplying intermittent pulsed volumes of lubricant from the lubricant supply arrangement to at least one lubricant pulse monitoring device including an elastic chamber to receive said pulsed volumes of lubricant from the pump, an outlet export valve at an outlet from the elastic chamber closing when a pulsed volume is delivered to the elastic chamber and opening to deliver the lubricant to the lubrication station, and a pressure transmitter measuring the pressure in said elastic chamber at least when a pulsed volume is received in the elastic chamber. A control computer regulating the pump controlling the pulses, closing the outlet export valve when a pulsed volume is delivered to the elastic chamber, controlling the measured pressure in the elastic chamber and opening the outlet export valve for deliverance of lubricant to the lubrication station. Also a corresponding method includes pumping intermittent pulsed volumes of lubricant to an elastic chamber, measuring the pressure in the elastic chamber when the elastic chamber has received a pulsed volume, controlling if the pressure corresponds to a required volume of lubricant, opening an outlet export valve at an outlet of said elastic chamber and emptying the elastic chamber and closing said outlet export valve to receive next pulsed volume of lubricant to the elastic chamber.

Abstract: A dual parallel outlet check valve includes a first one-way valve and a second one-way valve. The first one-way valve and the second one-way valve are normally closed valves. Both the first one-way valve and the second one-way valve are disposed in a valve housing, and the first one-way valve is disposed adjacent to and runs parallel with the second one-way valve. The first one-way valve allows lubricant to flow downstream from a fluid chamber to build a downstream pressure, thereby causing lubricant applicators to dispense lubricant. The second one-way valve allows lubricant to flow upstream back into the fluid chamber, thereby allowing the downstream pressure to drop and the lubricant applicators to reset.

Abstract: A system for greasing a valve is provided. The system comprises a main valve connected to a compressed fluid source, a grease supply system, a main chamber, a left head assembly, a right head assembly, and a grease supply line in communication with the valve. The main chamber includes a piston that is slidable from a first end to a second end of the main chamber. In the first position, the main valve injects fluid into the first end of the main chamber, thereby charging the left head assembly with grease and simultaneously discharging grease from the right head assembly into the grease supply line. In the second position, the main valve injects fluid into the second end of the main chamber, thereby charging the right head assembly with grease and simultaneously discharging grease from the left head assembly into the grease supply line.
