Description
Technical field
The utility model belongs to centrifugation pump technical field, relates in particular to a kind of device of elevator pump anti-cavitation performance.
Background technology
Centrifugal pump, refers to convey the pump of liquid by centrifugal force caused by impeller rotation, is widely used in major neck
Domain.Centrifugal pump is pump class product important in fluid machinery, it is with performance adaptability is high, small, the simple in structure, service life
Long, the advantages of convenient and reliable operation and maintenance cost are low.On the relatively low device of some net positive suction heads, cavitation phenomenons is incited somebody to action
Speed and pressure distribution of the fluid in pump can be changed, cause the operation of pump assembly unstable, and then make the flow, lift, effect of pump
Rate and shaft power are decreased obviously, and impeller destroys when serious, causes unit vibration, causes great loss.Common practice is,
Before centrifugal wheel set an inducer, for improving the cavitation performance of pump, its mechanism be exactly inducer regard as one it is auxiliary
The booster pump helped, it can work under certain level of cavitation, and can flow through the required flow of pump, while give fluid increase
Enough pressure heads, make centrifugal wheel that cavitation not occur when working.But inducer drawback is the operating mode difference of device, designs, casts,
Processing is different from, it is necessary to expend a large amount of human and material resources.
The content of the invention
The utility model provides a kind of device of elevator pump anti-cavitation performance, solves the inducer work in background technology
The shortcomings that condition different consumings a large amount of manpower and materials.
What the technical solution of the utility model was realized in：A kind of device of elevator pump anti-cavitation performance, including including
Motor, motor are connected with pump body, and the export pipeline of the pump body is equipped with diversion pipe, and diversion pipe is equipped with motor-driven valve and pressure
Power table, diversion pipe are connected with the pressure tank in inlet ductwork, and separator tube and reducer pipe are equipped between pressure tank and pump body；
Preferably, pipeline and reinforcing rib are set in the pressure tank.
The beneficial effects of the utility model are：The utility model is when cavitation phenomenons occurs in pump, on the export pipeline of pump
Convince head piece by patient analysis, motor-driven valve and pressure gauge are set, pressure gauge is observed by the folding of motor-driven valve, realizes that pump adds medium itself
Pressure, prevents the aggregation of bubble, flowing, divides and crumble and fall, pressure tank, puts pipeline and reinforcing rib inside pressure tank, increases water
The intensity and using effect of case, it is simple in structure, input cost is low, realize that effect maximizes with minimum cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Part explanation：1st, motor, 2, pump body, 3, export pipeline, 4, diversion pipe, 5, motor-driven valve, 6, pressure gauge, 7, import
Pipeline, 8, pressure tank, 9, separator tube, 10, reducer pipe.
Embodiment
For a better understanding and implementation, the utility model is further described below in conjunction with the accompanying drawings：A kind of elevator pump
The device of anti-cavitation performance, including be connected including motor 1, motor 1 with pump body 2, the export pipeline 3 of pump body 2, which is equipped with, leads
Flow tube 4, diversion pipe 4 are equipped with motor-driven valve 5 and pressure gauge 6, and diversion pipe 4 is connected with the pressure tank 8 in inlet ductwork 7, supercharging
Pipeline and reinforcing rib are equipped with water tank 8, separator tube 9 and reducer pipe 10 are equipped between pressure tank 8 and pump body 2.
When cavitation phenomenons occurs in pump, flow tube 4 is convinced by patient analysis on the export pipeline 3 of pump, motor-driven valve 5 and pressure gauge 6 is put, passes through
The folding observation pressure gauge 6 of motor-driven valve 5, realizes itself pressurization to medium of pump, prevents the aggregation of bubble, flowing, division and routed
Go out.
Diversion pipe 4 is controlled by motor-driven valve 5, observes the variation of 6 numerical value of pressure gauge, and medium is divided in pressure tank 8, water
The structure size of case is to calculate gained according to pipeline situation, puts pipeline and reinforcing rib inside pressure tank 8, realizes to impeller inlet
Locate the pressurization of medium, and play the role of buffering in channel interior pressure oscillation.
The utility model eliminates cavitation, protects impeller, makes operating steadily for pump, cost is low, and effect is good.
