Abstract: A pump monitoring system may include a sensor for monitoring a parameter of a pump system. The sensor may include at least one of an ammeter in electrical communication with an electric motor driving a pump and a torque sensor on a drive shaft that drives a pump. The system may also include a controller in data communication with the sensor to receive sensor data. The controller may be configured to assess the performance of the respective pump in one or more ways. At least one of the one or more ways may include reliance on the sensor data from only one sensor to identify valve or seat wear or failure. Alternatively or additionally, at least one of the one or more ways may identify valve or seat wear or failure without reliance on pump output pressure.

Abstract: Provided is a pump backstream prevention structure for semiconductor fabrication equipment, including a sensor, an isolation air supply pipe, and a control unit. A time delay from a point in time at which the dry pump starts to malfunction to a point in time at which the isolation valve is closed is reduced, compared to a method of closing the isolation valve by a controller of the semiconductor fabrication equipment. Accordingly, a backstream in which particles move from the pumping pipe to the process chamber before the closing of the isolation valve is prevented.

Abstract: A pump health monitoring system is provided. Such a system includes one or a plurality of data capture devices that together collect a multiple variable data set relating to a device being monitored such as a water pump device for a pool or spa and/or an underwater submerged pump device. A programmable processor receives the multiple variable data set, retrieves a set of processing rules that are specific to the identity of the pump and processes the operating details with the set of processing rules to identify a current operational status or health status of the device.

Abstract: A technique for monitoring valve and pump efficiencies for positive displacement pumps. The techniques include utilizing a data acquisition system to attain intake and discharge pressure data in combination with real-time encoder position data. Thus, when combined, output from a pump may be monitored in real-time. As a result, pump life may be extended beyond an anticipated changeout schedule. By the same token, premature pump inefficiencies may also be detected for taking a pump offline in advance of expected life. In either circumstance, multi-pump operations may be substantially enhanced with cost and time savings realized.

Abstract: A hydraulic pump performance deterioration detection system according to one embodiment includes: a variable displacement hydraulic pump; a switching valve that is connected to the hydraulic pump by a pump line and to a hydraulic actuator by a supply/discharge line; and a regulator that changes a displacement of the hydraulic pump in accordance with a command current and that limits the displacement of the hydraulic pump to a limiting value when a delivery pressure of the hydraulic pump has become higher than a setting value. The performance deterioration detection system further includes: control circuitry that feeds the command current to the regulator; and a pressure sensor that measures the delivery pressure of the hydraulic pump. When the hydraulic actuator is not moving, the control circuitry determines whether or not performance of the hydraulic pump has deteriorated based on a current value of the command current and the delivery pressure of the hydraulic pump measured by the pressure sensor.

Abstract: This disclosure includes plunger pumps having leak detection systems. Some pumps include a housing having a bore, an inlet, and an outlet, a plunger disposed within the bore and a first seal engaged with the plunger to divide the bore into first and second chambers, the plunger configured to reciprocate within the bore to expel liquid from the first chamber out of the outlet, and a sensor for detecting a presence of liquid in at least a portion of the second chamber. Some pumps have a reservoir for collecting liquid that leaks into the at least a portion of the second chamber, where the sensor is for detecting a liquid level in the reservoir. Some pumps include a second seal engaged with the plunger to divide the second chamber into first and second portions, and the sensor is for detecting a presence of liquid in the second portion.

Abstract: A method monitors the state of a device having a first drive cylinder for receiving hydraulic fluid and a first drive piston which is movably arranged in the first drive cylinder. The method determines a speed of the first drive piston, establishes a difference between the determined speed of the first drive piston and an expected speed of the first drive piston, and determines a faulty state as a function of the difference established between the determined speed of the first drive piston and the expected speed of the first drive piston.
