Description

Double-entry pump is opened in level
Technical field
The utility model relates to a kind of pump, particularly relates in a kind of level and opens double-entry pump.
Background technique
Open double-entry pump in level and refer to employing two imports outlet, the horizontal middle open type structure pump that multiple impeller full symmetric is arranged, its flow, lift can be very large, are the one of centrifugal pump, are also rely on the rotation of impeller to obtain centrifugal force.The mechanical seal pressure-bearing at pump two ends is inlet pressure, which decreases the pressure-bearing grade of machine envelope, namely reduces costs, and improves sealability.Drive multistage pump (single import) in existing level bulky, anti-cavitation performance is lower, the non-complete equilibrium of axial force, and high voltage terminal mechanical seal chamber pressure-bearing is higher, can affect the working life of pump.
Model utility content
The purpose of this utility model is to provide in a kind of level opens double-entry pump, to solve the shortcoming in above-mentioned background technology.
In order to achieve the above object, the utility model takes following technological scheme:
Double-entry pump is opened in a kind of level, comprise pump cover, pump seat and rotor part dress, described pump cover covers on described pump seat, described rotor part dress is run through in described pump seat, the two ends of described rotor part dress pass described pump seat, described rotor part is loaded onto and is provided with multiple impeller, described multiple impeller is arranged in described pump seat back-to-back, spiral case adopts double flow channel structure, described pump seat is provided with two suction ports and a discharge opening, two suction ports lay respectively at the two ends of pump, and pump two ends are low voltage terminal, and high-pressure section is in the middle of delivery side of pump and pump; The two ends of described rotor part dress are separately installed with front axle bearing portion dress and rear axle bearing portion dress, between described front axle bearing portion dress with described pump seat, described rear axle bearing portion fills and be equipped with oil blocking cover between described pump seat, is equipped with seal ring, low voltage terminal Seal cage seal ring before pump housing increasing back sealing ring, the pump housing between described impeller and described pump seat, pump cover.
In the utility model, under described pump seat, be connected with oil draining system and drainage.Described pump cover is connected with venting rinse-system.Described oil draining system, drainage are all connected with same outer pipe with venting rinse-system.Centered by described double-entry pump, line supports.
The beneficial effects of the utility model are: the utility model can be provided with different sealing configurations according to different operating mode, favorable sealing property, and adopt double flow channel structure, compact structure, beautiful shape, hydraulic efficiency and anti-cavitation performance are higher simultaneously; Pump seat is established two suction ports and a discharge opening, make not need during maintain and replace mechanical seal to dismantle pipeline, pump seat, motor and pump cover, fast easy to maintenance.And impeller is for install back-to-back, greatly balance axial force, and two of pump seat suction ports lay respectively at the two ends of pump, reduce the pressure-bearing grade of mechanical seal, extend the working life of mechanical seal.
Accompanying drawing explanation
Fig. 1 is the structural drawing 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, the structural drawing of double-entry pump of the present utility model, double-entry pump, comprise pump cover 11, pump seat 1 and rotor part fill 9, described pump cover 11 covers on described pump seat 1, to run through described rotor part in described pump seat 1 and fill 9, the two ends that described rotor part fills 9 pass described pump seat 1, described rotor part fills on 9 and is provided with multiple impeller 10, described multiple impeller 10 is arranged in described pump seat 1 back-to-back, spiral case adopts double flow channel structure, described pump seat 1 is provided with two suction ports and a discharge opening, pump two ends are low voltage terminal, high-pressure section is in the middle of delivery side of pump and pump, the two ends that described rotor part fills 9 be separately installed with front axle bearing portion fill 13 and rear axle bearing portion fill 7, described front axle bearing portion fills between 13 and described pump seat 1, described rear axle bearing portion fills between 7 and described pump seat 1 and is equipped with oil blocking cover 12, is equipped with seal ring 3, low voltage terminal Seal cage seal ring 2 before pump housing increasing back sealing ring 4, the pump housing between described impeller 10 and described pump seat 1, pump cover 11.
In the utility model, be connected with oil draining system 6 and drainage 5 under described pump seat, described pump cover 11 is connected with venting rinse-system 8, and described oil draining system 6, drainage 5 are all connected with same outer pipe with venting rinse-system 8.Centered by described double-entry 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 till now, alternative type of cooling (water-cooled, air-cooled, naturally cool), double flow channels, not only make the profile of pump more attractive in appearance, and further increase the reliability of pump.
Open double feed inlet pump intake and discharge opening in level of the present utility model all on fixed pump seat, when keeping in repair pump, 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 multistage 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.
Double-entry pump progression is opened many in level of the present utility model, pressure is high, but pumping chamber is arranged in the middle of the pump housing, and respectively there is a suction port at pump two ends, the pressure that the mechanical seal of such two ends is born is the pressure of suction port, unlike multistage pump have high and low pressure side point, reduce the pressure in mechanical seal chamber, extend the working life of mechanical seal; And improve the anti-cavitation performance of pump.Impeller adopts and installs back-to-back, greatly balances axial force, and spiral case adopts double flow channel structure, and radial force is balanced, and the bearing at pump seat two ends only need bear very little axial force and radial force, substantially prolongs the working life of bearing like this.
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 multistage 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.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
