Description
Technical field
The utility model relates to a kind of pump that utilizes solenoid actuated magnetic fluid, and particularly a kind of displacement pump relates in particular to a kind of displacement pump that utilizes solenoid actuated magnetic fluid.
Background technique
Pump is the fluid machinery of carrying liquid or making liquid supercharging, and it sends the mechanical energy of prime mover or other external energy to liquid, and liquid energy is increased.Pump is mainly used to carry the liquid such as water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal, also can conveying liquid gas mixture and containing the liquid of suspended solids.General service pump mainly contains centrifugal pump and displacement pump at present, centrifugal pump need inject a certain amount of liquid at water intake before work, while operating very inconvenient and load variations, (lift variation) flow also changes, and therefore can not meet the application of ask for something stability of flow.Displacement pump relies on and contains the cyclically-varying of hydraulic seal working space volume, makes to discharge by force after fluid pressure increase, so displacement pump not only has good self-priming characteristic and also have very stable flow in the time that load changes.Displacement pump is main point reciprocating pump and rotor pump at present, and wherein reciprocating pump has the feature of high pressure and small flow, suitable conveying clean liquid or gas-liquid mixture, and reciprocating pump mainly contains disk-shaped piston formula, plunger type, diaphragm type.Although disk-shaped piston formula reciprocating pump have advantages of pumping cylinder length compared with short, flow is large, exists pumping cylinder to be divided into two spaces, has the easily shortcoming such as leakage of pressure difference; Although it is high that cylinder-and-piston type reciprocating pump has pressure-bearing, there is the shortcoming that processing cost is high; Although diaphragm-type reciprocating pump has wear-resistant and corrosion-resistant, transmission efficiency is low.Rotor pump has the feature of higher vacuum and discharge pressure, can not contain the rigid impurity such as welding slag, iron filings but exist in material, so filter screen must be installed.Meanwhile, existing displacement pump adopts traditional mechanical structure, its transmission be connected use multiple component, make the complex structure of the pump housing and not easy to assemble cause difficult in maintenance.The displacement pump of traditional design is because use multiple component to make it have the loss of a large amount of frictional heat in rotational motion, and then reduced the efficiency of pump, thus also accelerated pump agingly affect working life.In addition, traditional displacement pump all adopts one-way valve at liquid entering hole and liquid outlet, and this has not only increased the part of pump, and makes pump structure more complicated.
Magnetic fluid, claims again magnetic liquid, ferrofluid or magnetic liquid, is a kind of functional material, the magnetic that it had not only had the mobility of liquid but also had solid magnetic material.A kind of stable colloidal liquid that magnetic retention particle, base load liquid and the interfacial agent three that this magnetic fluid is is nanometer scale (10 nanometers are following) by diameter mixes, it is nonmagnetic attraction force in the time of static state, when externally-applied magnetic field is done the used time, just show magnetic, it has a wide range of applications in practice just because of this, has in theory very high learning value.The magnetic fluid excellent performance of producing with nano metal and alloy powder, the fields such as magnetic fluid seal, damping, medical apparatus, the sound that can be widely used in various harsh conditions regulates, light display is shown, magnetic fluid ore dressing.
Promote simultaneously and improve displacement pump drive characteristic for overcoming traditional displacement pump shortcomings, the utility model proposes a kind of displacement pump that utilizes solenoid actuated magnetic fluid, this displacement pump adopts magnetic liquid to substitute traditional displacement pump component of machine, save complicated structure and various part compared with traditional displacement pump, reduced due to mechanical transmission and fricative idle work simultaneously.In addition, the utility model all needs one-way valve different from general displacement pump turnover liquid, and it can save liquid-inlet or export one of them one-way valve and further simplify the structure.
