Abstract
A pump including one or more pumping chambers, one or more drive mechanisms for driving the one or more pumping chambers and a logic arrangement. The first pumping chamber of the one or more pumping chambers has a first inlet check valve, a first outlet check valve and a first temperature sensor. The logic arrangement is configured to identify a leak by applying logic to at least resistance-data indicative of a resistance of the first pumping chamber to the driving and temperature-data at least based on output from the first temperature sensor.
Claims21
A pump including:
- two or more pumping chambers;
- one or more drive mechanisms for driving the two or more pumping chambers;
- and
- a logic arrangement;
- a first pumping chamber of the two or more pumping chambers having a first inlet check valve, a first outlet check valve and a first temperature sensor to measure a first temperature;
- a second pumping chamber of the one or more pumping chambers having a second inlet check valve, a second outlet check valve and a second temperature sensor to measure a second temperature;
- the logic arrangement being configured to identify a leak by applying logic;
- and
- the logic including:
- mutually comparing the first temperature and the second temperature;
- and
- mutually comparing a compression-stroke resistance of the first pumping chamber and a compression-stroke resistance of the second pump chamber.
A logic arrangement for a pump;
- the pump including:
- two or more pumping chambers;
- and
- one or more drive mechanisms for driving the two or more pumping chambers;
- a first pumping chamber of the two or more pumping chambers having a first inlet check valve, a first outlet check valve and a first temperature sensor to measure a first temperature;
- a second pumping chamber of the two or more pumping chambers having a second inlet check valve, a second outlet check valve and a second temperature sensor to measure a second temperature;
- the logic arrangement including one or more data inlets for receiving:
- resistance-data indicative of a resistance to the driving;
- and
- temperature-data at least based on output from the first temperature sensor and the second temperature sensor;
- and
- the logic arrangement being configured to identify a leak by applying logic;
- the logic including:
- mutually comparing the first temperature and the second temperature;
- and
- mutually comparing a compression-stroke resistance of the first pumping chamber and a compression-stroke resistance of the second pump chamber.
A method of identifying a leak in a pump;
- the pump including:
- two or more pumping chambers;
- and
- one or more drive mechanisms for driving the two or more pumping chambers;
- a logic arrangement;
- a first pumping chamber of the two or more pumping chambers having a first inlet check valve, a first outlet check valve and a first temperature sensor to measure a first temperature;
- a second pumping chamber of the one or more pumping chambers having a second inlet check valve, a second outlet check valve and a second temperature sensor to measure a second temperature;
- the method including the logic arrangement applying logic;
- the logic including:
- mutually comparing the first temperature and the second temperature;
- and
- mutually comparing a compression-stroke resistance of the first pumping chamber and a compression-stroke resistance of the second pump chamber.
