Abstract
Fully sealed magnetic pendulum pump is equipped with the single pendulum sheet that has magnet steel in the outside of the annular sap cavity of being made up of the pump housing and plastic diaphragms, and in annular sap cavity inside movable slider is housed.When the motor driving pendulum is done simple harmonic motion, movable slider in the magnetic attraction annular sap cavity by the magnet steel on the pendulum is done the simple harmonic motion transfusion, thus because liquid flows in hermetic annular sap cavity not the Contact Transmission part solved corrosion and leakage problem.The present invention can be used for the conveying of various liquid.
Description
The invention belongs to liquid capacity-changing mechanical.
When liquid such as strong acid, highly basic, severe toxicity are carried, for leakage that prevents liquid and the corrosion resistance that improves pump, often adopt the stainless steel material to make pump, or adopt rubber material to make transfusing chamber at present.As No. 3960466 disclosed rubber pipe pump of U. S. Patent.But the former costs an arm and a leg, and can not solve hermetically sealed problem, and the latter reduces its working life because of sebific duct is sharply aging under the situation of the long-term compressing distortion of roller.
The purpose of this invention is to provide a kind of can anti-strong acid, corroded by liquid such as highly basic, cheap all-sealed liquid pump.
Main points of the present invention are that the outside of the annular sap cavity be made up of the pump housing and plastic diaphragms is equipped with the pendulum that has magnet steel.And movable slider is housed in annular sap cavity inside.When the motor driving pendulum is done simple harmonic motion, do the simple harmonic motion transfusion by the movable slider in the magnetic attraction annular sap cavity of the magnet steel on the pendulum.Thereby the Contact Transmission part has not solved corrosion and leakage problem because liquid flows in hermetic annular sap cavity.
Details of the present invention illustrates with the following example and accompanying drawing.
Fig. 1 is the fully sealed magnetic pendulum pump structural representation.
Fig. 2 is fully sealed magnetic pendulum pump A-A facet figure.
(1) is the water intake of pump among the figure, (6) be that the water outlet (3) of pump is the pump housing, an annular sap cavity (18) is arranged on the pump housing (3), in two outsides of the pump housing (3) barrier film (4) is arranged, the barrier film outside is to be connected with fulcrum (8) on front pump cover (5) rear pump cover (7) rear pump cover (7), dead man (9) is housed on the fulcrum (8), dead man (9) lower end connects with pendulum (10) lower end by pulling out axle (13), magnet steel (11) is equipped with in pendulum (10) lower end, pendulum (10) upper end is fixing with balance staff (2), an off-centre is housed at the middle part of dead man (9) pulls out axle (12).Annular sap cavity (18) top downside has the mouth of a river (19) to communicate with water intake (1), and it is airtight with it that water intake tongue (15) is housed; There is the mouth of a river (20) to communicate at annular sap cavity (18) top upper side, and water outlet tongue (17) is housed its sealing with water outlet (6).In annular sap cavity (18) bottom movable slider (4) is housed, barrier film (4) front cover (5) in the pump housing (3) two outsides, rear end cover (7) compresses it by nut, makes annular sap cavity (18) complete closed, and movable slider (14) can only swing in annular sap cavity (18).Spacer block (16) is arranged at annular sap cavity (18) top, when motor rotation drive off-centre is pulled out axle (12) rotation, off-centre is pulled out axle (12) drive dead man (9) and is swung, dead man (9) drives pendulum (10) again and does simple harmonic motion, inhaling moving movable slider (14) by the magnetic force of the magnet steel (11) on the pendulum (10) makes in annular sap cavity (18) of the step swing, separated by barrier film (4) between magnet steel (11) and the movable slider (14), the most handy permanent magnetic material of magnet steel (11) is made.When movable slider (14) has a side sap cavity volume progressively to enlarge in annular sap cavity (18) when swinging aside, water outlet tongue (17) is closed, and water intake tongue (15) is opened liquid is sucked from water intake (1); And opposite side sap cavity volume dwindles gradually, and water intake tongue (15) is closed, and water outlet tongue (17) is opened outside the liquid excavationg pump.When movable slider (14) then repeats imbibition and discharge opeing process when back swinging.Similar two plunger cases of movable slider (14) reciprocally swinging are in motion, so its infusion process is successional.
In order to increase corrosion resistance, the available engineering plastics of the pump housing (3) are manufactured, and movable slider (14) outside is surrounded by one deck polytetrafluoroethylene, also can select for use without material at liquid of different nature.
In carrying the liquid process, have only annular sap cavity contact with liquid, and transmission part is to swing by magnetic force drive movable slider with movable slider, contact liq not, thus solved etching problem and fluid leakage problems.For carrying strong acid, liquid such as highly basic provide a kind of transfusion machinery of safety and reliability.
