The utility model adopts vertical structure, has saved the space, cabin on naval vessel; Take the mechanical seal form, improved sealability, improved the mechanical seal working environment; Be provided with cyclone hydraulic separators, high-pressure medium entered along separator madial wall tangent line high velocity jet, and in housing high speed rotating, can isolation of purified medium, prolong working life of pump; Use the double seal ring structure, prevent that medium from entering shaft seal cavity, quicken the medium circulation in the shaft seal cavity, strengthen the spinning liquid separating effect of separator; On motor, have bigger window, can exempt the inspection time receiving and all dismantle the trouble that inner body could overhaul, take out internal works from window and can repair.
Now described in conjunction with the accompanying drawings.
Fig. 1 is the utility model sectional arrangement drawing.
Fig. 2 is a vertical projection diagram of the present utility model.
Fig. 1 and Fig. 2 have shown structure of the present utility model and principle, and full pump comprises power, outside and inner three assemblies.Power assembly is by motor 21, connecting flange 20, and shaft coupling 19 is formed, and motor 21 is fixed on the top of motor frame 22, and by the seam location, connecting flange 20 is enclosed within on the shaft extension of motor 21, and is connected with shaft coupling 19 by the seam location.Outside assembly is by the pump housing 2, and motor frame 22 and supporting post 4 are formed, and it is heavy that supporting post 4 plays the auxiliary pump that carries, and the pump housing 2 is located by seam with electric frame 22 and connected fastening with bolt 9.Have big window on the motor frame 22, can utilize this window dismounting inner components and convenient maintenance.Outer wall at motor frame 22 is equipped with cyclone hydraulic separators 1, by pipeline cyclone hydraulic separators 1 is connected with the turnover water channel of the pump housing 2 and the shaft seal cavity in the pump cover 10.Inner assembly is by impeller 6, mechanical seal 8, and pump cover 10, axle 13, bearing support 15, shaft coupling 18, upper bearing (metal) 25, lower bearing 12 is formed.Whole inner assembly is located by the pump cover 10 and the seam of the pump housing 2, and connects fastening with bolt 9.Above several major parts use bolton on the basis by the footing flange on the pump housing 2.
The mechanical seal of single end face unbalanced type cemented carbide friction pair is adopted in shaft sealing of the present utility model.Described mechanical seal 8 is contained on the axle 13, this shaft part position is surrounded by the shaft seal cavity that pump cover 10 itself is had, on the cylindrical of the machine envelope spring seat 27 of the low-pressure cavity separated place of shaft seal cavity and impeller 6 rear ends, have reverse spiral chute, to improve the working environment of mechanical seal.
Cyclone hydraulic separators is a funnelform conical shell.The high-pressure medium in fork-like farm tool used in ancient China self-pumping outlet port enters along the madial wall tangent line high velocity jet of cyclone hydraulic separators 1, and in the funnel housing high speed rotating, solid particle contained in the medium (sand grains etc.) is descended with rotation and action of gravity, and flow back to the low pressure area of pump with the part medium from cyclone hydraulic separators 1 lower end by pipe and pipe joint 28.The medium that the center hole on cyclone hydraulic separators 1 top flows out fork-like farm tool used in ancient China has obtained separating and has purified and delivered to shaft seal cavity through pipe, the mechanical seal friction pair is washed and cools off, thereby improved the working environment of mechanical seal, operating life that can the prolonged mechanical sealing.In order to promote the ringing of cyclone hydraulic separators 1, impeller 6 is designed to the double seal ring structure, be equipped with seal ring 3 at the import and the back of impeller 6, and lean against wheel hub at impeller 6 and have 4-6 aperture, make impeller 6, seal ring 3, pump cover 10.Machine envelope spring seat 27 formed cavitys are communicated with pump low pressure area (suction eye).Like this, the pressure of this cavity is less than the pressure of shaft seal cavity, and the medium that contains solid particle just can not enter shaft seal cavity by the outer rim place that machine seals spring seat 27, but flow to the impeller suction from the balance aperture.For making this state more reliable, on the cylindrical of machine envelope spring seat 27, have reverse spiral chute, make this groove can prevent that when pump rotates containing granule medium enters shaft seal cavity thus, can quicken media flow circulation in the shaft seal cavity, make the spinning liquid separating effect better.
When mechanical seal leakage, outside the areola excavationg pump on the top that leakage fluid can be by pump cover 10.Between bearing 12, be provided with oil sealing 11 at areola, prevent that leakage fluid from entering bearing bore.Simultaneously, 12 on bearing also is provided with one sealing against leakage liquid in the lower openings place and enters bearing bore.
The utility model also is provided with quick repair apparatus.In coupling 18, be provided with shaft coupling 19, when maintenance, then shaft coupling 19 can be pulled down as long as remove the connecting bolt of elastic sleeve pin 23 and connecting flange 20 and shaft coupling 19 earlier; Then, shed the connecting bolt 9 of the pump cover 10 and the pump housing 2, use demounting bolt 26 again, utilize the window on the motor frame 22 then independent taking-up of inner assembly can be overhauled inner assembly jack-up.And impeller nut 5, round nut 24, plug screw 29 unload next all dismounting.
