Definitions
- This invention concerns an improved electromagnetic system for vibrating piston pump with an isolated compression chamber suitable for moving liquids; consisting of an electromagnetic system which drive in alternative sense a magnetic core extended into a plunger acting as the compression mean that impels the liquid in a compression chamber towards an outlet.
- the vibrating pump which is the subject of this invention, has features intended to increase the efficiency of the electromagnetic driver system due to a specific metallic structure, an axially flexible plunger comprising two or more different materials and the assembly of the compression chamber by clipping methods, allowing it to obtain similar performances of current vibrating piston pumps with less cooper, iron and lower assembly costs while consuming less electricity during operation.
- the choice of the type of pump basically depends on the requirements it must meet, such as: dimensions/weight, maximum pressure, maximum flow, flow at working pressure, power consumed, characteristics of the fluid to be moved (oils, acids, food, etc.), price or noise level.
- Vibrating piston pumps which are of the type referred to in this invention, work by alternatively moving a magnetic core using a tubular electro-magnet around the said magnetic core.
- the use of AC to power the electro-magnet generate magnetic pulses that go from zero to maximum at the pace of the AC. These magnetic pulses attract the magnetic core from an upstream position to a downstream position.
- a spring placed downstream of the magnetic core is compressed and push said magnetic core back to its upstream position when the magnetic pulse is zero producing the alternative movement thereof.
- the electromagnetic systems currently used in vibrating pumps as described in DE 20 2007 019 534 U1 or DE 10 2012 107 983 A1 has a low efficiency due to fact that the magnetic force responsible for moving the plunger from its upstream to the downstream position is created by the use of two separated bushings.
- plunger Another key component on the efficiency of the magnetic system of vibrating solenoid pumps is the plunger. Due to the design, manufacturing specifications and materials currently used there is room to improve its efficiency and costs. To manufacture pistons, three processes are the most commonly used nowadays: full machining starting from a larger piece of stainless steel, press-bonding the ferritic stainless-steel core and the stainless-steel plunger or by plastic moulding a plunger over the ferritic stainless-steel core. All the existing plungers are rigid and without axial flexibility between the core and the piston.
- an object of the present invention is to provide a vibrating piston pump with improved magnetic efficiency, lower noise and easier assembly enabling to obtain the performances of current piston pumps with less raw material, mainly cooper, and manufacturing costs.
- the vibrating piston pump for liquids comprising: an electromagnet constituted by a metallic structure and a coil, being said electromagnet the driver force that move longitudinally and in alternate direction a pumping means inside a driver chamber.
- the pumping mean is composed of a magnetic core, two springs, one at each side of that core and a plunger attached to said magnetic core.
- the springs are responsible first to keep the magnetic core in a rest position and second to accumulate the energy produced by the displacement of the magnetic core. When the magnetic flow come to zero the energy accumulated in the springs bring the magnetic core back to its rest position. This process repeats at the AC frequency and the pump works under the principle of a spring-mass system.
- a second feature of the vibrating pump of this invention is the axial flexibility of the plunger relative to the magnetic core.
- the plunger is solidly assembled to a magnetic core but with freedom of axial movement between both parts. This axial flexibility lowers the noise level of the pump.
- the magnetic core is simple to manufacture and with few machining operations, thus reducing machining costs and waste of raw materials in the form of shavings.
- the plunger assembled to said magnetic core is a separate piece that can be made of any material compatible with the characteristics of the fluid to pump.
- the axial flexibility is given by the patella shape end of the plunger and the semi-housings that link the plunger to the magnetic core.
- the semi-housings can be obtained from plastic or rubber injection and improve the useful life of the pumping means which is exposed to high vibration frequencies.
- the third feature of the vibrating pump of this invention is the use of a fork shaped clip to join the compression chamber with the electromagnetic driver resulting in a compact and easy to assembly vibratory pump.
- the vibrating piston pump includes an electromagnetic system comprising a coil (1) and a metallic structure composed by a "U” shaped piece (2), two bushings (7.1, 7.2), a lower plate closure (3) and a screw stud (4).
- the "U” shaped piece (2) is placed around the coil (1), the two bushings (7.1, 7.2) are placed inside the said coil (1) and the lower plate (3) is placed below, on the open side of the "U” shaped piece (2), closing the magnetic circuit with the screw stud (4).
- the lower plate (3) is fixed by the screw stud (4) to a driver chamber (5) which is positioned inside the coil (1) and the two bushings (7.1, 7.2).
- a pumping mean moving axially and in alternative direction composed by a magnetic core (6) and a plunger (9) linked to the top of said magnetic core (6) by a semi-housings set (11).
- the movement of the pumping mean is produced by a spring-mass system and the energy exchange system is composed by a compression spring (19) positioned below the bottom of the magnetic core (6) and a return spring (8) positioned above the top of the magnetic core (6).
- the fluid to impel is displaced in a compression chamber (12) with an inlet (17) and an outlet (18) which is assembled to the driver chamber (5) and fixed by the fork shape clip (13).
- the plunger (9) is attached to a magnetic core (6) by a semi-housing set (11) and has axial flexibility relative to the magnetic core (6) due to the patella design of the plunger's end linked to said magnetic core (6).
- the compression chamber (12) is housed in the upper side of the driver chamber (5) and fixed by the fork shape clip (13) that holds the compression chamber (12) assembled and free to rotate 360°.
- a sealing means (14) and a washer (15) prevents the fluid to leak from the compression chamber (12) to the driver chamber (5) and the seal (16) keeps the compression chamber (12) and the driver chamber (5) under tension to prevent vibration noise
