Background technique
This cooling blower is a vitals of 220 tons of mine electric wheel dumps (abbreviation dumping car) cooling system, during fan operation, cooling-air is transported to rapidly around the dumping car motor, the heat that motor is produced is taken away, thereby reaches the purpose of air cooling engine.According to the requirement of dumping car cooling system, cooling blower need be depressed and can meet flow at 20 ℃ of standard atmospheres: 4 m
3the declared working condition of/s, static pressure 6700Pa.And existing mine electric wheel dump is not high by cooling blower efficiency, vibration is large, noise is high and maintenance is inconvenient, do not reach technical requirements.
Summary of the invention
The purpose of this utility model is to overcome deficiency and the defect of prior art, provide have that reliability is high, efficiency is high, it is little to vibrate, noise is low, the 220T mine electric wheel dump cooling blower of compact structure and the characteristics such as easy to maintenance.
The technical solution of the utility model: a kind of 220 tons of mine electric wheel dump cooling blowers, comprise transition air channel, outlet(discharge) flange, seal disc, impeller and spiral case, it is characterized in that described this cooling blower is designed to the cooling blower of the direct driving structure of dumping car motor;
Described impeller is forward multiple wing formula centrifugal impeller structure, and this impeller is comprised of rear trochal disc, blade, front wheel disc and core wheel, this wherein, the blade in impeller is the forward-type curved blade, blade quantity is 32; Characteristics with high pressure, low noise.
Described spiral case is comprised of back side panel, top board, circular arc plate, front side plate and slip ring, and the matching gap of this slip ring and impeller is 2 ± 1mm; The transition air channel of a 90-degree bent of exhaust outlet place welding of spiral case;
Due to the excellent aeroperformance of impeller, effective control of slip ring and impeller fit up gap and the optimized design of Scroll's flow field have guaranteed that the fan airflow noise reaches floor level.
Described spiral case and impeller directly are assemblied in by the engine-driven main shaft of dumping car, be that the dumping car engine spindle stretches into impeller from spiral case slip ring one side, make slip ring directly be welded on the attachment face on spiral case right side, the spiral case right side is bolted on dumping car motor one side, impeller is fixed on the shaft extension end of dumping car motor by locking nut and lock washer, and seal disc is bolted on the left side of spiral case.
This cooling blower is designed to forward multiple wing formula centrifugal impeller structure, and blower fan self is not equipped with motor, and the component such as spiral case and impeller directly are assemblied on the main shaft of motor of dumping car, by motor, are directly driven.Engine spindle stretches into impeller from spiral case slip ring one side, makes slip ring directly to be welded on the attachment face on spiral case right side.The spiral case right side is bolted to motor one side by 8 M30's, and impeller is fixed on by locking nut and lock washer on the shaft extension end of motor, and seal disc is by the left side that is bolted to spiral case of 12 M8.
It is forward multiple wing formula centrifugal impeller that this cooling blower focuses on impeller, and wherein impeller blade adopts the forward direction arc form, and this kind of structure be in the situation that impeller size is limited, has pressure high, the characteristics that noise is low.Supporting the use of slip ring and spiral case makes air velocity distribution further optimize, and makes compressor flow and pressure be improved, thereby reaches the purpose that improves fan efficiency.Excellent aeroperformance due to impeller, the optimized design of intake duct, impeller, the configuration of volute space optimization and impeller inlet diameter and slip ring crest clearance has guaranteed that the fan airflow noise reaches floor level, makes the noise of blower fan lower than 110 Lw dB(A).The dynamic balance of impeller precision reaches the G2.5 level simultaneously, and the coaxality of impeller and slip ring reaches φ 1, makes fan vibration speed be less than 2.8mm/s.
Spiral case adopts the Archimedes spiral abundant optimization airflow of type structure flow field, makes the high velocity air from impeller effectively be converted into fan static pressure, improves blower pressure.For meeting the requirement of the special ventilation duct of dumping car, the transition air channel of a 90-degree bent of spiral case exhaust outlet place welding, realized the function of blower fan from radially giving vent to anger and axially giving vent to anger.Transition air channel and spiral case exhaust outlet place utilize the circular arc plate smooth transition, reduce the exhaust outlet resistance as far as possible, promote fan efficiency.Because the spiral case right side is mounting plane, slip ring must be integrally welded with spiral case, slip ring circularity and with the coaxality of impeller by guaranteeing than the high technology level.
This blower fan is except the core wheel of impeller, and all parts all adopt aluminum alloy material, makes blower fan have lightweight characteristics, and the blower fan gross weight is less than 150kg.
In sum, the utility model reliability is high, efficiency is high, it is little to vibrate, noise is low, compact structure and the characteristics such as easy to maintenance.It is a kind of Centrifugal cooling fan machine of high pressure low noise.
