Abstract
The invention relates to a detachable fineness grading series integral-type seal-sealing magnetic filter, which is researched and developed by aiming at the problems that a single-stage oil absorption filter element for a traditional concrete pump hydraulic system is easy to block and the length of time of designed oil-through capacity is short. In the filtering mode of the single-stage filter element, the surface of the filter element is easily and rapidly adhered by various contamination particles with different sizes in oil, so that the oil-through capacity of the filter element is reduced, and further, an oil pump cannot absorb enough oil, and cavitation is generated. In actual use, the generated immediate consequences are shown as follows: a main oil pump is frequently damaged, and the oil absorption filter element is frequently replaced. A primary filter element connected in series onto the oil absorption filter comprises a coarse filter element or filter screen and is used for removing larger contamination particles by filtration; and a secondary filter element is a fine filter element for ensuring the cleanness of the system. As the coarse filter element filters the larger contamination particles by filtration, the oil filtering capacity and the service life of the fine filter element are effectively ensured. The filter is the same as a current accessory in installation dimension, is similar with the current accessory in cost and is an effective substitute product for upgrading the current accessory.
Description
One, technical field:
The present invention relates to a kind of concrete pump hydraulic system and use the oil suction filter.Be particularly useful for adopting the hydraulic system of high-grade plunger pump.Also be applicable to the hydraulic system of other various machinery.
Two, the state of the art:
Modern project machinery and various jumboes have adopted Hydraulic Power Transmission System widely.In all kinds of Hydraulic Power Transmission Systems for the performance reliability and working life of the various hydraulic element in the protective system effectively; The oil suction filter must be set at the inlet port of hydraulic-pressure pump come the various impurity particles in the filtering fuel tank fluid, guarantee the turbidity test of system's inner fluid.
At present, the self-priming oil suction filter technology in the available coagulation soil pump hydraulic system all is that the one-level filter core adds the magnetic adsorbent equipment and again for being convenient for changing the manual self-styled valve that filter core is provided with before filter core.Though the filter type of this single-stage filter core can guarantee filtering traffic and the turbidity test requirement of system to fluid at the use initial stage; But prolongation along with service time; Various impurity particles not of uniform size can promptly stick to the surface of filter core in the fluid, make it cross oily ability and greatly reduce.This situation develops into certain degree, or forces the user to shut down more renew cartridge, otherwise can cause the oil pump oil suction not enough, produces cavitation erosion and damages oil pump.Because concrete pump is as long as in-cycle work just can not request stop, it is exactly that main oil pump damages frequent and the replacing of oil suction filter core frequently that this situation is used the direct result that is produced in reality.The main oil pump of concrete pump mostly adopts import constant voltage plunger pump, and more than 50,000 yuan of RMB of every price has brought very big economic loss to the user, has also raised the cost of building indirectly.
Three, goal of the invention and solution:
The object of the invention is exactly be prone to stop up and designed short and just disassembly-type thickness grading research and development of the oily ability endurance one-piece type self-styled magnetic filter of connecting to existing single-stage oil suction filter core.The elementary filter core that is connected on the oil suction filter is made up of coarse filter element or filter screen, by the bigger impurity particle of its filtering; Secondary filter core is only the smart filter core into guaranteeing that system's turbidity test require.Since the coarse filter element filtering bigger impurity particle, the oil strain ability of smart filter core with obtained effectively assurance working life.The two-stage filter core of this filter is installed in series in same cylindrical shell, is convenient to dismounting, changes smart filter core and cleans coarse filter element; When dismounting, replacing and cleaning filter core, the fluid in the fuel tank can not leak owing to manually self-styled.
Solution of the present invention is: thickness grading is connected one-piece type self-styled magnetic filter push rod 1, end cap 2, smart filter core 5, urceolus 6, magnet ring 8, middle cover 11, spring 15, coarse filter element 16, be formed by combining from big envelope 17.Right-hand member at smart filter core 5; Coarse filter element 16 is placed in the endoporus from big envelope 17; By the outer garden of the left end boss of coarse filter element 16 and end face location and with form one cavity volume from the endoporus of big envelope 17, the fluid coarse filter element 16 of must flowing through is after its filtration; Just can get into the inner chamber of smart filter core 5, so just by coarse filter element 16, form elementary coarse filtration from big envelope 17; Form the smart filtration grade of magnetic by end cap 2, smart filter core 5, urceolus 6, magnet ring 8, middle cover 11.When smart filter core 5 of needs dismounting and change and cleaning coarse filter element 16; As long as turn push rod 1 it is withdrawed from; Coarse filter element 16, will under the effect of spring 15, follow push rod 1 from big envelope 17 and be moved to the left,, compress O type circle when being adjacent to from the end face of big envelope 17 right-hand member boss and the right side of middle cover 11; Closed oil inlet passage, unclamped end cap 2 again and just can take out smart filter core 5, magnet ring 8, coarse filter element 16.Reinstall after changing smart filter core 5 and cleaning coarse filter element 16 and get final product.
Classified filtering of the present invention is compared with existing single-stage filtering technique; Because thickness impurity is by classified filtering; Promoted the oil filling capacity and the working life of oil suction filter effectively, and then guaranteed the performance reliability and the working life of all elements in main hydraulic-pressure pump and the system.
Four, description of drawings:
Accompanying drawing 1 is a structural drawing of the present invention.
Five, mode of execution:
Embodiment of the present invention is: when starting oil pump; Radial direction through hole and urceolus 6 internal diameters of fluid in the fuel tank from the urceolus 6 right-hand member cylindrical shells and the gap between big envelope 17 right-hand member end face cylindricals flow to urceolus 6 and middle cover 11 and from the cavity volume of big envelope 17 compositions; The fluid that flows to this cavity volume flows to coarse filter element 16 and the cavity volume of forming from big envelope 17 through the radial direction through hole on big envelope 17 right-hand member cylindrical shells; Behind the bigger impurity particle of coarse filter element 16 filterings; Flow to by end cap 2, smart filter core 5, middle cover 11, coarse filter element 16 and the cavity volume formed from big envelope 17 etc.; Through being sucked into hydraulic-pressure pump behind the less impurity particle of smart filter core 5 filterings, metal granule less in the fluid is adsorbed on it by magnet ring 8.When smart filter core 5 of needs dismounting and change and cleaning coarse filter element 16; As long as turn push rod 1 it is withdrawed from; Coarse filter element 16 and will under the effect of spring 15, follow push rod 1 from big envelope 17 and be moved to the left when being adjacent to from the end face of big envelope 17 right-hand member boss and right side with middle cover 11, compresses O type circle; Closed oil inlet passage, unclamped end cap 2 again and just can take out smart filter core 5, magnet ring 8, coarse filter element 16.Reinstall after changing smart filter core 5 and cleaning coarse filter element 16 and get final product.Unclamping push rod 1 and in the process that big envelope 17 is closed, the mechanical seal between push rod 1 and the end cap 2 has prevented leaking outside of fluid.
