3//h, efficiency is 79%), and operational excellence, adopt rectangularl runner structure, Volute Design becomes double volute form simultaneously, substantially radial force can be balanced, can reduce the vibration of pump, improve the working life of bearing and sealing, pump structure form is open in level simultaneously, to suck, discharge opening pump seat both sides horizontal position below axis, the layout complete equilibrium of double-sided impeller axial force.Supporting way changes center line into and supports, and effectively improves the performance of pump running.Compact structure, beautiful shape, hydraulic efficiency and anti-cavitation performance are higher
Accompanying drawing explanation
Fig. 1 is the structural drawing of an embodiment of the present utility model;
Fig. 2 is the left view of an embodiment of the present utility model.
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
As shown in Figure 1, high-lift single-stage double-suction centrifugal pump of the present utility model draws together pump cover 7, pump seat 6 and rotor part fill 3, described pump cover 7 covers on described pump seat 6, to run through described rotor part in described pump seat 6 and fill 3, the two ends that described rotor part fills 3 pass described pump seat 6, described rotor part fills on 3 and is provided with a double-entry impeller 16, described runner is rectangularl runner, the two ends that described rotor part fills 3 be separately installed with front axle bearing portion fill 2 and rear axle bearing portion fill 12, described front axle bearing portion fills between 2 and described pump seat 6, described rear axle bearing portion fills between 12 and described pump seat 6 and is equipped with oil blocking cover, described impeller 16 and described pump seat 6, seal ring 9 before impeller is equipped with between pump cover 7, low voltage terminal Seal cage seal ring 8.Described high-lift single-stage double-suction centrifugal pump has two suction chambers, a pumping chamber, and described pumping chamber is arranged in the middle of the pump housing.In accompanying drawing 1,1 is coupling portion dress, and 4 is bearing gland, and 11 is integrated mechanical sealing.
In the utility model, be connected with oil draining system 13 and drainage 14 under described pump seat, described pump cover 7 is connected with venting rinse-system 10, and described oil draining system 13, drainage 14 are all connected with same outer pipe with venting rinse-system 10.Centered by described high-lift single-stage double-suction centrifugal pump, line supports.
Structure of the present utility model is from compact type pumps such as traditional integral pump pin, water-cooling type bearing support, the huge type of single spiral case equal-volume split type technique pump pin 15 till now, alternative type of cooling (water-cooled, air-cooled, naturally cool), double volutes, not only make the profile of pump more attractive in appearance, and further increase the reliability of pump.
In the utility model, the suction port of high-lift single-stage double-suction centrifugal pump and discharge opening all on fixed pump seat, when pump is keeped in repair, without the need to detaching pipelines and motor, and maintain and replace mechanical seal and bearing time, do not need to tear pump seat and pump cover open, dismounting is extremely simple.The runner of pump adopts scroll casing type, but not the guide-vane of general centrifugal pump pump, and therefore pump can keep higher hydraulic efficiency, and the efficient district of pump is wide, and the efficiency of pump is all up to state standards more than A line or A line.
High-lift single-stage double-suction centrifugal pump of the present utility model is η=78% by the efficiency A line of this pump of NBS, B line is 70%, complete machine combined test by my test center of company: the utility model pump is a kind of efficient, single-stage, high-lift oil transportation centrifugal pump, unit has high efficiency, high reliability, high-quality manufacturing process, pump efficiency is greater than 80% (and specific speed only has 64), and efficiency is higher than national A line standard; Vibration values is maximum is only 2.7mm/s, lower than same kind of products at abroad standard.Suction port and discharge opening are all located on pump seat, and making does not need during maintain and replace mechanical seal to dismantle pipeline, pump seat, motor and pump cover, soon easy to maintenance.
Bearing body part is made up of parts such as bearing support, bearing gland, sliding bearings.Bearing structure is completely with reference to API610 standard design, and thrust-bearing adopts the installation form back-to-back of pair-wise combination installation; In order to reduce bearing temperature rise, bearing shell being lengthened, increasing the area of contact of bearing shell, widening the width of oil ring in addition, and be provided with small circular grease chamber at the internal surface of oil ring; Structure is installed by original footing and is changed present center line mounting structure into, greatly reduces the vibration of unit, thus extends the working life of mechanical seal and bearing, for user provides cost savings.
High-lift single-stage double-suction centrifugal pump pressure of the present utility model is high, but delivery chamber is arranged in the middle of the pump housing, and the pressure that the mechanical seal of such two ends is born is the pressure of suction port, reduces the pressure in mechanical seal chamber, extends the working life of mechanical seal; And improve the anti-cavitation performance of pump.In the utility model, pump housing oil draining system, drainage, the outlet of venting rinse-system all gather and to be connected with the external world, meet environmental requirement, the utility model makes two stage pump from without Monitoring and Controlling remote monitoring up till now, really achieve on-the-spot unattended, integrate with completely with external advanced pump level.
