The seventies has carried out research and design at northern area for Farming Submersible Pumps, but immersible pump enterprise of China saves for material
It is not the state taking much count of that design about is in a kind of substantially, the cost concept of overseas enterprise's especially Japanese enterprises than
Domestic much better than, they utilize various advanced technology means to improve the conservancy property of pump, the wear and corrosion behavior improving pump
The application of paint-on technique, surface treatment technology of material and nonmetallic materials is combined closely, but domestic current existing latent
There is the problems such as flow is little, lift is low in water pump, serious mistake have impact on the utilization of the underground water of agricultural.
Therefore, a big flow, high-lift, the one of small-well-diameter are realized for overcoming the deficiency of above-mentioned technology and designing
Novel centrifugal axial flow combined type immersible pump, inventor's problem to be solved just.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel centrifugal axial flow combined type diving
Pump, its simple in construction, it is achieved big flow, high-lift, small-well-diameter, the sand control ability of product can be greatly increased, permissible
Extend service life.
The utility model solves its technical problem and be the technical scheme is that a kind of novel centrifugal axial flow combined type diving
Pump, it includes shaft coupling, water inlet joint, pump shaft, impeller, tapered sleeve, blower inlet casing, upper blower inlet casing, and described shaft coupling is connected with impeller,
It is provided with tapered sleeve outside described impeller, outside described tapered sleeve, is provided with water inlet joint, bottom described water inlet joint, be connected with blower inlet casing, institute
State blower inlet casing to be connected with upper blower inlet casing, inside described immersible pump, be provided with labyrinth type sand control installation, described labyrinth type sand control installation
Including sound sand control ring and outside framework oil seal, sound sand control ring is arranged on outside outside framework oil seal.
The beneficial effects of the utility model are:
1st, the utility model submersible pump structure is that pump is assembled into one, and impeller is fixing uses tapered sleeve, and motor uses up and down
Thrust structure, adds labyrinth type sand control installation in overall design, prevent water medium sand grain from entering motor cavity and water pump bearing leaf
Wheel, at core surface spraying silver slurry, makes the roughness of critical component surface of internal cavity and casting quality and yield rate all be improved,
Thus ensure that efficiency of pump Xinjiang region underground water sand content is relatively big, sand grains once enters each bearing portion of the pump housing, by a high speed
Rotating, will quickly wear and tear upper and lower thrust bearing, pump guide bearing, and impeller, blower inlet casing choma ultimately cause unit and scrap, by increasing
If sound sand control ring, outside framework oil seal form labyrinth type sand control installation, greatly increase the sand control ability of product, extend use
Life-span.
2nd, the utility model design parameter for be suitable for minimum hole diameter be 350mm, single-stage lift be 30m, latenter than existing respectively
Water pump is suitable for the little 50mm of hole diameter, single-stage lift is doubled, and reduces manufacturing cost and improves product simultaneously and be suitable for model
Enclosing, the Hydraulic Design of impeller uses the centrifugal and coefficient principle of axial-flow type, by adjusting each geometric parameters of hydraulic model
Number, blade is changed into half distortion by full distortion, makes outlet blade angle become certain relation with blower inlet casing vane inlet angle, will immersible pump
The water export relation at a right angle with blower inlet casing stator makes into less than 90 ° so that current have upwards potential energy, and increases impeller and enter
Outlet area of passage, reaches to improve the purpose of single-stage lift, and the utility model has that hole diameter is little, lightweight, consumptive material is few, single-stage is raised
Journey advantages of higher, increases inlet velocity, reduces suction eye diameter and impeller outer diameter, reduces subtended angle of blade simultaneously,
Full distortion is changed blade into half distortion so that it is have that production cost is low, rational in infrastructure, energy-efficient, operate steadily, install and make
By features such as convenience, applicability are wide.
