Abstract
A system detects Differential Pressure Short Stroking by comparing the expected lubricant flow with the actual lubricant flow as determined by either manual timing stokes of a flow analyzer or automatically receiving signals corresponding to strokes of the analyzer and calculating the flow.
Claims11
A system for detecting whether the quantity of lubricant being application to a compressor is correct, comprising:
- a lubricant pump;
- a multiple output divider block for providing lubricant to multiple injection points on a compressor system;
- multiple single input/single output divider block analyzers, each multiple single input/single output divider block analyzers in line with an injection point;
- an analyzer having an input and a display and comprising:
- a processor;
- a memory storing computer instruction to be executed by the processor to:
- accept input of the amount of lubricant per cycle of a single input/single output divider block;
- accept signals from a proximity switch indicating cycles of the single input/single output divider block;
- calculate an actual amount of lubricant being delivered in a specific time period;
- compare an actual amount of lubricant being delivered in a specific time period to a prespecified expected amount of lubricant being delivered;
- and
- indicate on the display whether or not the actual amount of lubricant delivered in the specified time period is within a specified range.

A method of detecting whether or not a divider block lubrication system is providing a prescribed amount of lubrication to a natural gas compressor, comprising:
- providing a fluid flow analyzer in line with an injection point on the natural gas compressor, the fluid flow analyzer ejecting a known amount of fluid for each cycle of the fluid flow analyzer;
- providing a processing system;
- inputting into the processing system the amount of lubricant ejected during each cycle;
- determining the frequency or period of cycles of the fluid flow analyzer;
- calculating by the processing system the actual amount of lubricant being injected at the injection point by multiplying the amount of lubricant ejected during each cycle by the number of cycles in a prescribed time period;
- comparing by the processing system the actual amount of lubricant being injected at the injection point with a predetermined expected value of lubricant being injected at the injection point;
- if the actual amount of lubricant being injected at the injection point differs from the predetermined expected value by a predetermined threshold, alerting an operator to the discrepancy;
- investigating and correcting the reason for the discrepancy, thereby reducing premature wear on the compressor system.
