Abstract
A vane pump for delivering pasty masses, in particular sausage meat, with a pump case 6 and a rotatably held rotor 3 comprising vanes 2 held so as to be radially movable which form delivery cells 4 together with the wall 5 of the pump case 6, with a suction area, a pressure area and a sealing area separating the pressure area from the suction area. For a better sealing between the suction area and the sealing area, in particular in case of high pressures in the pressure area, and for increasing the service life of the vane pump, in the sealing area at least one sealing element is provided for sealing a gap between the rotor and the wall of the pump case.
Claims17
Vane pump for delivering pasty masses, in particular sausage meat, comprising a pump case having a wall, a rotatably held rotor comprising vanes held so as to be radially movable and which form delivery cells together with wall of the pump case, a suction area, a pressure area and a sealing area separating the pressure area from the suction area, and at least one sealing element provided in the sealing area for sealing a gap between the rotor and the wall of the pump case, and a vacuum extension in the sealing area in the pump case, at least one sealing element being arranged in the sense of rotation upstream of the vacuum extension.
Vane pump for delivering pasty masses, in particular sausage meat, comprising a pump case having a wall, a rotatably held rotor comprising vanes held so as to be radially movable and which form delivery cells together with the wall of the pump case, a suction area, a pressure area and a sealing area separating the pressure area from the suction area, at least one sealing element provided in the sealing area for sealing a gap between the rotor and the wall of the pump case, the sealing element comprising a leakage channel opened at least partially towards the rotor for removing pasty mass entrained at the circumferential surfaces of the rotor, and the leakage channel being in communication with one of a leakage channel in a side plate covering the case, or with a leakage channel in the case to remove the entrained pastry mass.
Vane pump for delivering pasty masses, in particular sausage meat, comprising a pump case having a wall, a rotatably held rotor comprising vanes held so as to be radially movable and which form delivery cells together with the wall of the pump case, a suction area, a pressure area and a sealing area separating the pressure area from the suction area, at least one sealing element provided in the sealing area for sealing a gap between the rotor and the wall of the pump case, the sealing element comprising a leakage channel opened at least partially towards the rotor for removing pasty mass entrained at the circumferential surfaces of the rotor, and the sealing element comprising n-sealing surfaces and n−1 leakage channels situated in-between (nεIN).
Vane pump for delivering pasty masses, in particular sausage meat, comprising a pump case having a wall, a rotatably held rotor comprising vanes held so as to be radially movable and which form delivery cells together with the wall of the pump case, a suction area, a pressure area and a sealing area separating the pressure area from the suction area, at least one sealing element provided in the sealing area for sealing a gap between the rotor and the wall of the pump case, a vacuum extension in the sealing area in the case, at least one sealing element being arranged in the sense of rotation upstream of the vacuum extension, and with the sealing area comprising the following structure:
- a first sealing section with a first sealing gap formed between the rotor and the wall of the case,
- a second sealing section with at least one first sealing element,
- a third sealing section with a second sealing gap formed between the rotor and the wall of the case, and
- a fourth sealing section comprising at least one further sealing element.
Vane pump for delivering pasty masses, in particular sausage meat, comprising a pump case having a wall, a rotatably held rotor comprising vanes held so as to be radially movable and which form delivery cells together with the wall of the pump case, a suction area, a pressure area and a sealing area separating the pressure area from the suction area, at least one sealing element provided in the sealing area for sealing a gap between the rotor and the wall of the pump case, the sealing element comprising a leakage channel opened at least partially towards the rotor for removing pasty mass entrained at the circumferential surfaces of the rotor, and the sealing element comprising n-sealing surfaces and n−1 leakage channels situated in-between (nεIN), and each of the sealing surfaces is a lip.
