摘要： The object of providing a cerebrospinal fluid drainage system 1 which reacts precisely to changes in pressure in the cerebrospinal fluid, with ease of operation, is achieved by the present invention in that a pump 5 is used for draining the cerebrospinal fluid (liquor), wherein operating measured values supplied by sensors act as controlled variable for the operation of the pump. The pressure in the liquor line currently measured by a pressure sensor 10, the liquor pressure in the intracranial cavity being treated, measured intracorporeally by a pressure sensor, and/or the volume of liquor already pumped out, as operating measured value, can, for example, serve as the basis for operational control of the pump of the liquor drainage system. The liquor drainage system according to the invention has the advantage that the liquor is drained not only simply on the basis of the excess pressure in the intracranial cavity being treated, but is actively pumped out of the intracranial cavity in a controlled manner, in particular with constant measurement of the liquor pressure. In this way the pumping capacity can be regulated depending on requirement and the drainage pressure or the liquor pressure kept reliably within a specific pressure range.

摘要： A system and method are disclosed for monitoring and controlling a positive displacement pump using readings obtained from a plurality of pressure sensors. The pressure sensors may be mounted at the suction, discharge and interstage regions of the pump. Signals from the pressure sensors are compared to obtain a ratio that is used to predict whether a cavitation condition exists within the pump. The ratio can be compared to user provided limits to change an operating characteristic of the pump to reduce predicted cavitation. The pump may be stopped, or pump speed changed, when the ratio is less than a predetermined value. In some embodiments, historical information regarding the ratio may be used to obtain standard deviation information which may then be used to predict whether gas bubbles are passing through the pump. Other embodiments are described and claimed.

摘要： A structure for sensing refrigerant flow rate in a compressor. The structure includes a passage forming member, a restriction hole, a differential pressure-type flow rate sensor, and a partition plate. The compressor includes a housing connected to an external refrigerant circuit via a refrigerant passage. The passage forming member is connected to an outer surface of the housing and forms a part of the refrigerant passage. The restriction hole divides the refrigerant passage into an upstream passage and a downstream passage. The upstream passage is formed in either the housing or the passage forming member. The sensor is provided in the passage forming member and detects pressure in the upstream passage and pressure in the downstream passage to sense flow rate of refrigerant in the refrigerant passage. The partition plate is disposed between the housing and the passage forming member. The restriction hole is formed in the partition plate to extend through the partition plate.

摘要： A method of determining a leakage in a piston machine comprising at least two pistons is provided. The rotational velocity of the piston machine, and therefore the volume flow through the piston machine, is varied periodically as part of a time-limited active test while measuring the differential pressure and the angular position. An angular position-based Fourier analysis of the measured values from differential pressure and rotational velocity measurements performed during the test are used to experimentally determine the amplitude ratio and phase angle difference between volume flow variations and pressure variations. The amplitude ratio and phase angle difference are used, together with an angular position-based Fourier analysis of the measurements of differential pressure and rotational speed made after the active test, to determine the amplitude and phase of the leakage flow.
