Definitions

  • the present invention is directed to an improved pump and pump connection system, and in particular to a pump having a quick connect coupling between the pump head and the pump motor providing quick mounting and release of the pump to a mounting surface, and is also directed to a pump a controller and performance monitoring including sensors for detecting problems and possible failure.
  • Positive displacement pumps and in particular diaphragm pumps are used for various applications. Depending upon the type of application, the pumps may need to be maintained or have components replaced. Many smaller diaphragm pumps include a pump head assembly that mounts to the motor. Rather than replacing the entire pump should the pump fail, during maintenance, it may be possible to simply replace the motor or the pump head.
  • Such pumps may therefore fail without any warning to operators. It is also possible for inexperienced users to unknowingly operate the pumps in potentially damaging ways. Small diaphragm pumps are often used by turf/sprayer equipment operators, high end recreational vehicle owners, in agriculture, and construction equipment operators. These pumps are typically used outdoors and deal with a variety of working fluids including water, bleach, pesticides, and fertilizers. As downtime is critical, delays in determining when a pump fails can be very damaging and costly. When in a remote environment away from service technicians to replace the pumps or diagnose the issue, inexperienced users may conduct maintenance incorrectly and put the pump in to damaging operating conditions without knowing.

  • Such a connection should provide for a quick engagement as well as quick decoupling of the components.
  • Such a system should also eliminate the need for tools and loose retaining hardware.
  • the connection and disconnection of the pump head to the pump motor is further improved if workers may simply use their hands to manually connect and disconnect the component assemblies.
  • a quick connect mounting assembly of the pump to a surface without the need for tools or loose mounting hardware would further speed maintenance and provide for easier inspection and repair. Such mounting of the pump to a surface should be quickly and easily performed by a worker without the need for tools.
  • Such a pump should further be configured so that the quick connect between the pump head and the motor and a quick release system for mounting the pump do not interfere with one another and may be actuated separately and independently.
  • such pumps should provide for continuously monitoring performance and/or failure and providing information to operators to prevent pump failure.
  • Such a system should be capable of sensing failure events, predicting the likelihood of failure events, monitoring the state of the pump head, and taking action to interrupt operation when a failure event occurs and indicate to the operator the status of the pumping system. In this way the operator can take appropriate action and conduct maintenance or repair activities before total system failure occurs.

  • Different control actions may be used to respond to different sensing and triggering events. These actions can be classified in two distinct categories; 1) alarm actions that are intended to protect the pumping system such as termination of operation, and 2) warning actions to notify the operator important information that may impact the pumping system negatively but is not currently causing malfunction.

  • the controller/processor (220) includes an exterior user interface (250) having a display (hidden in Figure 21 ) that provides an indication of the status of the pump's operations.
  • the user interface (250) includes a display with status indicators to show a mode or current operational status of the pump.
  • the user interface (250) includes LED indicator lights.
  • a run light (252) indicates that the pump is in a normal operating condition.
  • a service light (254) indicates that the pump requires maintenance and/or repairs.
  • a failure light (256) indicates that the pump has failed and is not operating.
  • the failure indicator (256) may also include an associated audible alarm.
  • a diagnostic light (258) indicates that the pump is in a diagnostic mode.
  • the diagnostic mode is activated my placing a magnet (260) over the diagnostic light (258) that is sensed by the user interface (220).
  • the indicator lights (252, 254, 256, 258) have different colors to provide a quick visual indication of the operational status of the pump.
  • the interface (250) provides for diagnosing problems and setting up operation of the pump (100).
  • the failure light (256) will turn ON while the water/contamination is in contact with the moisture sensor (206).
  • the failure light (256) changes to flashing after the detection of moisture until the controller (220) is reset. This notifies the operator a leak was previously detected but not detected currently. Only when a leak is actively detected will the pump be OFF by the relay unit (210).
  • the service light (254) will turn on when a predetermined time limit is exceeded, such as 400 hours.
  • the magnet (260) is used to reset the device, although a switch or other actuation could also be used depending on the application and site where the pump is operating.
  • the magnet is held on the interface (250) over the failure light (256).
  • One or more of the lights (252, 254, 256, 258) or combinations of the light may blink and/or show solid to indicate start of reset and then change to indicate that the reset is complete.
  • the controller/processor (220) and interface (250) provide for a diagnostic mode, which may be indicated by the diagnostic light (258).
  • the magnet (260) is placed proximate the user interface, such as against the diagnostic indicator light (258) as shown in Figure 24 .
  • a combination of flashing by one or more of the lights may indicate that the controller/processor (220) is in diagnostic mode.
  • the magnet (260) may then be removed.
  • the failure light (256) and the service light (254) may flash in particular patterns that may indicate the number of times the pump monitor system (200) has been reset and/or to indicate the total number of hours the pump has been operating.
  • the pump monitoring system (200) is able to detect conditions that may require maintenance. When a triggering event such as scheduled maintenance or a problem are indicated by the monitoring system (200), the pump may be shut down by a switch, disconnecting the cord (190) or through the controller (220). The entire pump (100) may then be released from its mounting position by actuating the handle (158) of the pump mounting assembly (150) and lifting the pump (100) from the mounting assembly (150). Independently, the pump head (102) may also be simply removed by moving the locking pin (146) radially outward to disengage the hole (148B) and then rotating the pump head (102) relative to the motor (104) until the engagement elements (144) are moved to the first arm portion (114) of the L-shaped slot (112).
  • the pump head (102) may then be simply pulled apart from the motor (104). It can also be appreciated that the drive shaft (106) is aligned with the complementary receiving slot and simply slides into and out of the slot (132) without the need for any tools or adapters. If the pump head (102) and the motor (104) are satisfactory following inspection, they may be simply be reassembled. However, if either the pump head (102) or the motor (104) needs replacement, these assemblies may be replaced and the replacement components are connected to one another, placed in the cradle (152), and mounted again to a mounting surface. Moreover, certain operational features of the controller (220) may be reset as appropriate. Reconnection of the cord (190) or actuation of a switch or the controller (220) would restart the pump (100).
