Abstract: A milk pump device, comprising a passage duct, a first one-way valve, a second one-way valve and a membrane pump. The first and second one-way valves are included in the passage duct and oriented in the same direction relative to each other. The membrane pump is positioned between the first one-way valve and the second one-way valve. The membrane pump forms a first milk meter for generating a first milk measurement with respect to a number of complete pumping strokes of the membrane pump. The milk pump device further comprises a second milk meter for carrying out a second milk measurement with respect to a residual pumping stroke.

Abstract: Various functions of a production oil well are monitored to cause a switch closure for each normal cycle of the pump. Alternatively, the level of the fluid within the well is monitored to cause the switch closure. The switch closure activates a first oscillator whose count is compared with a variable frequency oscillator over a given period of time to ascertain the percentage of time of normal operation. The integrated time is adjusted to shut down the system when the percentage of time drops to or below the preselected amount. In response to the integration timer signal, a shutdown timer is turned on which restarts the cycle after a preselected amount of time. When the system is restarted by the shutdown timer, a pump-up timer is turned on which is adjusted to allow for a desired pump-up time. As the pump-up timer is allowing the system to recycle, the integration timer is reset and the recycling is completed if the requirements of the integration timer are met. Otherwise, the unit is shut down again and the system recycled. A variable electronic scaler is connected to the output of the integration timer which monitors the output signals from the integrator timer. After the preset number of times the integration timer produces a signal, unless reset by a normal cycle, the scaler turns off the whole system. It can then be restarted manually.

Abstract: A valve in the production flow line of an oil well closes a reed switch indicative of fluid being pumped through the line. The switch closure activates a first oscillator whose count is compared with a variable frequency oscillator having a frequency of approximately one half that of the first oscillator. The comparison is made over a given period of time to ascertain the percentage of time the valve has been open and passing fluid. Theoretically, the valve should be open 50 percent of the time because 50 percent of the time is taken on the downstroke of the pumping assembly when no production is occurring. The integrated timer is adjusted to shut down the system when the percentage of time the valve is open drops to the preselected amount, usually equal to or less than 50 percent. In response to the integration timer producing a signal, a shutdown timer is turned on which restarts the cycle after a preselected amount of time. When the system is restarted by the shutdown timer, a pump-up timer is turned on which is adjusted to allow for a desired pump-up time. As the pump-up timer is allowing the system to recycle, the integration timer is reset and the recycling is completed if the requirements of the integration timer are met. Otherwise, the unit is shut down again and the system recycled. A variable electronic scaler is connected to the output of the integration timer which monitors the output signals from the integrator timer. After the preset number of times the integration timer produces a signal, the scaler turns off the whole system. It can then be restarted manually. This provides a safety device for equipment failure such as breaking of the sucker rod. Means are also provided for recording the various timed cycles and also for monitoring the number of signals transmitted to the scaler, thus being indicative of the number of times the system has automatically shut down.

Abstract translation: 油井生产流水线中的阀门关闭一个指示流经泵管的流体的簧片开关。 开关闭合激活第一振荡器，其计数与具有大约是第一振荡器的一半频率的可变频率振荡器进行比较。 在给定的时间内进行比较，以确定阀门打开和通过流体的时间百分比。 理论上，阀门应该打开50％的时间，因为在没有生产的时候，50％的时间是在泵组件的下冲程中进行的。 当阀门打开的时间百分比下降到预先选定的数量时，通常调节关闭系统的时间，通常等于或小于50％。 响应于产生信号的积分定时器，关闭定时器被打开，在预选的时间量之后重新启动循环。 当系统由关机定时器重新启动时，启动一个抽油定时器，该定时器被调节以允许期望的泵送时间。 由于抽油机定时器允许系统回收，如果满足积分计时器的要求，则积分计时器被复位，并且回收完成。 否则，本机再次关闭，系统回收。 可变电子缩放器连接到积分计时器的输出，该定时器监视来自积分器定时器的输出信号。 在集成定时器产生信号的预设次数之后，缩放器关闭整个系统。 然后可以手动重启。 这提供了用于设备故障的安全装置，例如抽油杆的断裂。 还提供了用于记录各种定时周期并且还用于监视发送到缩放器的信号的数量的装置，因此指示系统自动关闭的次数。

Abstract: A pressure tank fault detector and method provides a system (10) for detecting a fault in a pressure tank (12). The system includes a current transformer (40) positioned adjacent a pump power wire (22). A circuit (42) includes a timer (44), a data recorder (46), and a system status indicator (48). When the pump (18) operates, the current transformer (40) signals the circuit (42) and the timer (44) measures the signal duration. The data recorder (46) logs a short cycle when the timer (44) measures less than a selectable predetermined amount of time. When two or more short cycles are recorded, an alarm is produced. Preferably, the system (10) includes a test circuit (74) and allows selection of the number of short cycles before the alarm and whether to record only consecutive short cycles. Optionally, the system (10) detects and signals pump cycles exceeding a predetermined excessive run time.

The landfill pump cycle counter is configured to receive liquid output from a landfill pump. The housing extends along an axis and also defines an inlet and an outlet. The internal passage fluidly connects the inlet to the outlet. The poppet is configured to be moved axially between an open state and a closed state. The counter includes a magnetic sensor configured to detect a poppet cycle. The poppet cycle includes the poppet moving from one of the open state and the closed state to the other of the open state and the closed state.

Abstract: An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.
