Definitions
- Liquid ring gas pump with; a silencer body in the pressure chamber
- the tubular noise-absorbing body is provided so that it can be decided on a case-by-case basis whether it is used or not.
- the invention can be inserted from the outside into the assembled pump through the pressure port, so that normal pumps can be retrofitted with the noise-absorbing body without this having to be taken into account during assembly or storage.
- the noise damping body is preferably a pipe section guided in the pressure nozzle, wherein a special device can expediently be provided in the pressure nozzle to hold the noise damping body.
- this is an elastic sealing ring that can be inserted in a circumferential groove of the pressure connector, by means of the frictional force of which the tube inserted as a noise damping body is held in the pressure connector.
- a shoulder or the like can be provided on this pipe, which, in cooperation with the holding means or the sealing ring, prevents an unintentional sinking into the pressure chamber.
- a support stop is provided in the pressure chamber, on which the lower end of the tube used as a noise-damping body is supported.
- Fig.l shows a cross section along line II-II of Fig.2
- Fig.2 shows a longitudinal section along line II of Fig.l.
- the control disk 3 contains one or more pressure openings 5, through which the compressed medium with part of the operating fluid passes from the working space 1 into the pressure space 4.
- the pressure nozzle 6 At the pressure chamber 4 adjoins the pressure nozzle 6 through which the gas and the operating fluid excess is removed.
- the pressure port is arranged vertically. This is advantageous but not absolutely necessary.
- a tubular noise damping body 7 can be used in the pressure connection 6, the diameter of which is a little smaller than that of the pressure connection. If it is desired that its inside diameter corresponds approximately to the nominal diameter of the connecting line, the pressure connection can be made with a correspondingly larger diameter. Usually this is not considered necessary.
- an annular groove 8 is provided as standard in the pressure connection 6, into which an elastic ring 9 can be inserted, which holds the pipe section 7 in a manner that is tolerant and rattle-free in relation to the pipe connection 6.
- a step 10 serving as a stop support is arranged in the pressure chamber on the housing, on which the lower end of the pipe section 7 rests at a circumferential point touches down without significantly reducing the free flow cross section of the pipe section.
- the invention makes it possible to retrofit a series pump in the case of high demands on noise damping with the noise damping body, without having to make any changes to the assembled pump as such.
- the tubular noise damping body has a circular cross section. However, it can have a different cross section. This applies in particular to its lower end, which plunges into the pressure chamber. It also need not be tubular in its entire length. The tube shape also need not be closed over the entire circumference. However, this is expedient in the section in which the noise damping body lies within the pressure connection so that it can be kept uniform on all sides.
- the noise damping body ends at the bottom in an end face extending at right angles to its longitudinal direction. Since the wall formation in relation to the remaining area of the pressure chamber and, in particular, the position of the lower wall edges of the noise damping body are important with regard to the noise damping function, the lower end edge of the noise damping body can also have a different shape. For example, it can be provided that it extends further down on its side facing the pressure openings 5 than on its opposite side.
- openings are provided in its length range immersed in the pressure chamber, which openings are distributed uniformly or irregularly over its circumferential surface, through which openings the medium can enter in addition to its front end opening.
- the noise damping body is double-walled, the two walls being tightly connected to one another at the top, with a buffer space that is open towards the bottom towards the pressure chamber to build.
