摘要： The invention concerns a dosing pump for moving a fluid, comprising a dosing head in which there is a dosing chamber and a displacement element reciprocatable between a first and a second position, wherein the displacement element delimits the dosing chamber, and the volume of the dosing chamber in the first position of the displacement element is greater than the volume of the dosing chamber in the second position of the displacement element, wherein the displacement element is coupled to a linear motor by way of a stroke element in such a way that in operation of the linear motor the stroke element performs a forward stroke and a return stroke in a housing in a direction of a movement axis with a stroke length h and the displacement element is reciprocated between the first position and the second position. To provide a dosing pump and to improve dosing pumps which are driven with a linear motor it is therefore proposed according to the invention that the stroke element has a cross-sectional area Q perpendicularly to the movement axis, wherein the square of the stroke length h is at least forty times greater than the cross-sectional area Q.

摘要： A diaphragm unit for a diaphragm pump includes a diaphragm core and a multi-layer pump diaphragm connected to the diaphragm core. The pump diaphragm has a fluid-impermeable working layer which comes into contact with a fluid to be delivered, and a fluid-impermeable safety layer. A sealed volume for receiving fluid passing through the working layer is arranged between the working layer and the safety layer. A first clamping region of the diaphragm forms a ring which annularly surrounds the diaphragm core. To detect a rupture of the working diaphragm layer, at least one element of a sensor is provided within the ring formed by the first clamping region for detecting fluid which penetrates into the sealed volume.

摘要： A peristaltic pump includes a casing having a bottom, cover and wall forming a pump chamber, a tube connecting a casing inlet to a casing outlet arranged within the pump chamber, and a displacement element having at least two displacement members. The tube is arranged between the casing wall and the displacement element in such a way that due to rotation of the rotor the displacement members roll on the tube so the tube is squashed together so that a medium to be conveyed which is in the tube is displaced in the direction of the casing outlet. The displacement element has a first part fixed to the rotor and a second part which can be reciprocated between an operative position and a change position.

摘要： A measuring device for determining the filling level of a filling material in a container is simple and inexpensive to produce and allows largely continuous determination of the filling level of an unknown filling material in a container. The measuring device has at least three measuring sensors in mutually spaced relationship in a heightwise direction. A read-out device having at least three measuring inputs for reading out the measuring sensor signals is provided. Each measuring sensor signal depends on material properties of a filling material arranged adjacent to the respective measuring sensor. A calibration device which effects calculation of the filling level detected by a measuring sensor positioned neither right at the top nor right at the bottom in the heightwise direction, on the basis of the measuring sensor signal of the further upwardly arranged measuring sensor and/or the further downwardly arranged measuring sensor.

摘要： The invention relates to a device for generating a pulsating hydraulic fluid pressure in a working chamber (1) filled with hydraulic fluid, comprising a driveable working piston (4) movably guided in a hollow working cylinder, wherein a working chamber (1) that is in fluid communication with the working piston (4) is provided, such that, by means of the movement of the working piston (4) within the hollow working cylinder, a pulsating hydraulic fluid pressure can be generated in the working chamber (1). In order to provide a device for generating a pulsating hydraulic fluid pressure and in particular a diaphragm metering pump comprising such a device, which has small dimensions and in addition a rapid passage through the phase between closing the suction valve and opening the pressure valve, according to the invention, an auxiliary piston (20) is movably guided in a hollow auxiliary cylinder and is in fluid communication with an additional chamber (18, 21), wherein a closeable auxiliary channel (22), which connects the additional chamber (18, 21) and the working chamber (1), is provided, wherein the auxiliary piston (20) and the hollow auxiliary cylinder are formed and arranged in such a way that, by moving the auxiliary piston (20) within the hollow auxiliary cylinder, a hydraulic fluid arranged in the additional chamber (18, 21) can at least partly be forced out of the additional chamber (18, 21) into the auxiliary channel (22) and from the auxiliary channel (22) into the working chamber (1).

摘要： A displacement pump includes a delivery chamber, connected to a pressure connection and a suction connection. A displacement element determines the volume of the delivery chamber and can be moved back and forth between a first position, in which the delivery chamber has a smaller volume, and a second position, in which the delivery chamber has a larger volume. The pressure connection is connected to the delivery chamber by a pressure valve and the suction connection is connected to the delivery chamber by a suction valve. The displacement pump is easy and economical to produce and simultaneously reliably provides a degassing function, whereby downtimes can be reduced and the reliability of the delivery process can be increased. With the pressure valve closed, a backflow channel connects the delivery chamber and pressure connection, through which medium can enter the delivery chamber and/or gas can escape from the delivery chamber.

摘要： The present invention concerns a diaphragm pump comprising a delivery chamber separated from a hydraulic chamber by way of a diaphragm, wherein the delivery chamber is respectively connected to a suction connection and a pressure connection and the hydraulic chamber which can be filled with a working fluid can be acted upon with a pulsating working fluid pressure and the diaphragm can be reciprocated between a pressure position in which the volume of the delivery chamber is smaller and a suction position in which the volume of the delivery chamber is larger. In that arrangement the hydraulic chamber is connected to a working fluid supply by way of a leak replenishment valve, wherein the leak replenishment valve is so designed that when the pressure in the hydraulic chamber in the suction position of the diaphragm is less than a predetermined minimum value pMin the leak replenishment valve opens and the hydraulic chamber has an outlet passage which is closed by a pressure limiting valve which is so designed that if the pressure in the hydraulic chamber rises above a predetermined maximum value pMax the pressure limiting valve opens and working fluid can leave the hydraulic chamber by way of the outlet valve. To provide a corresponding diaphragm pump which automatically reduces the metering power in the overpressure situation without the use of additional sensors being necessary it is proposed according to the invention that the working fluid supply is arranged in a first and in a second chamber, the two chambers being connected together by way of a first connecting passage.

摘要： A diaphragm pump includes a pumping chamber, suction and pressure connections, a working chamber filled with a hydraulic fluid, a device for applying an oscillating pressure P1 to the hydraulic fluid, and a diaphragm separating the pumping chamber and the working chamber moveable between a pressure stroke position and a suction stroke position. A storage chamber accommodates hydraulic fluid at a pressure P2. The storage chamber and the working chamber are connected to each other by a valve having a closing part. The diaphragm cannot move too far beyond the pressure stroke position. The diaphragm is coupled to the closing part so that the valve is opened when the diaphragm moves from the pressure stroke position to a position that is farther from the suction stroke position than the pressure stroke position.
