摘要： A compressor system is provided that includes a contact cooled compressor and a coolant separator. The coolant separator is used to remove coolant fluid from a compressed flow stream produced by the contact cooled compressor during its operation. The coolant separator routes the removed coolant fluid back to the contact cooled compressor for further use. In some forms the coolant fluid is cooled prior to delivery back to the compressor. A stop valve can be provided in the coolant fluid return line to halt the flow of the fluid. A pressure sensitive member can be disposed to sense pressure of the coolant fluid that has been routed past the stop valve. Operation of the compressor can be changed as a result of the sensed pressure from the pressure sensitive member. Information from a temperature sensitive member can also be used to change operation of the compressor.

摘要： A diaphragm pump includes motor that drives an armature in a reciprocating linear motion. A first diaphragm is coupled to a first end of the armature, the first diaphragm positioned in a first pumping chamber and configured to pump fluid into and out of the first pumping chamber in response to the reciprocating linear motion of the armature. A cooling intake valve and a cooling exhaust valve are in operative communication with the first diaphragm, wherein as the armature advances to flex the first diaphragm to decrease a volume of the first pumping chamber, the first diaphragm draws ambient air behind the first diaphragm through the cooling intake valve, and wherein as the armature reverses course to cause the first diaphragm to increase the volume of the first pumping chamber, the first diaphragm forces ambient air out of the first pumping chamber through the cooling exhaust valve.

摘要： Illustrative embodiments of diaphragm pumps including a sensor mount are disclosed. In one illustrative embodiment, a diaphragm pump may include a shaft disposed within a pump housing and coupled to at least one diaphragm, a mount removably attached to the pump housing and having a sensor receptacle, and a proximity sensor received in the sensor receptacle of the mount such that a sensing end of the proximity sensor is flush with an end of the sensor receptacle nearest the shaft.

摘要： A control system for controlling a refrigerated dryer of a gas compressor system includes a controller and a flow sensor and can be selectively operated in a power saving mode in which the controller shuts down a refrigerant compressor included in the dryer system when the flow sensor indicates that no compressed gas is flowing through the dryer. The control system uses input from a temperature sensor to determine whether to activate the compressor regardless of the flow of compressed gas through the dryer.

摘要： A power tool is provided. The tool has a housing containing an internal drive system that drives an output member that engages a workpiece and exerts mechanical force thereupon. A force sensor and a positional sensor are operatively connected to the drive system to sense characteristic variables of the drive system during engagement of the workpiece. A light unit is positioned on a front end and a top portion of the housing so as to be able to direct light of various colors onto the workpiece. A control unit is operatively connected to the drive system and the light unit so as to control the light unit based on the characteristic variables of the drive system measured by the sensors. The light unit may illuminate a colored light on the workpiece depending on whether or not the workpiece was determined to be fastened according to predetermined specifications.

摘要： A diaphragm pump having a crankshaft that is rotatable about a rotational axis and coupled to a piston. The piston is reciprocally displaceable within a piston cylinder along an axis of motion between suction and discharge strokes. A diaphragm housing coupled to the piston cylinder at least partially defines a pumping chamber through which fluid is pumped as the piston reciprocates. The axis of motion, which intersects a connection between the piston and the connecting rod, may not intersect the rotational axis of the crankshaft such that, relative to an arrangement in which the axis of motion does intersect the rotational axis, a peak magnitude of piston side load forces during the discharge stroke is reduced and a peak magnitude of piston side load forces during the suction stroke is increased so as to attain an improved balance between the peak magnitudes of piston side load forces of the discharge and suction strokes.

摘要： A centrifugal compressor impeller includes a plurality of blades on a front side that extend from a first axial side to an outer radial end of the impeller. The centrifugal impeller includes a back side having a nonlinear backwall. The backwall can include a flat area hear a bore of impeller, a flat area near a tip of the impeller, and a convex surface between the flat areas of the bore and the tip. In some forms the impeller further includes a concave surface between the convex surface and the tip to form an s-shape. A transition or inflection point can denote the change from convex to concave. The convex and/or concave surfaces can take any variety of forms such as constant radius sections and/or compound curves.

摘要： A computer may display on a graphical user interface (GUI) a component library including a set of components relating to a compressed air system. The GUI may have a modeling interface for configuring a virtual model using the set of components. The computer may simulate the virtual model to determine one or more optimizations to the compressed air system. The computer may also determine the cost of implementing the compressor system optimization.

摘要： A compressed air drying system is provided for removing moisture from compressed air. The dryer operates in two modes in response to the demand for compressed air. In a first mode of operation, a refrigeration compressor runs continuously and the speed of a condenser fan is varied to maintain a constant cooling temperature. In a second mode of operation, the refrigeration compressor runs intermittently between on and off periods. As result, the cooling temperature fluctuates during the second mode of operation.

摘要： A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.
