Embodiment
The combination accompanying drawing further specifies the utility model device below.
A kind of rough vacuum, the big rate of air sucked in required vacuum pump of milking comprises rotor shaft core 3, bearing 2 and 11, rotor 5 in pump case 8 and the pump case 8, and rotor 5 is connected with rotor shaft core 3, and the two ends of rotor shaft core 3 are provided with bearing 2 and 11; The two ends of pump case 8 are provided with forward and backward end cap 1,12.On rotor 5, prolong rotor 5 and be axially arranged with blade groove 7, correspondence is provided with the movable cyclone sheet 6 of scraping in blade groove 7, and the width of scraping cyclone sheet 6 is not less than the poor of pump case 8 inner chambers and rotor 5 radiuses; On pump case 8, be provided with suction port 10 and air outlet 9; The position of suction port 10 is, crouches when putting rotor 5 sense of rotation one side at vacuum pump; The position of air outlet 9 is, crouches when putting the side that rotor 5 sense of rotation are opposite at vacuum pump.
Front cover 1, bearing 2,11, rotor shaft core 3, retainingf key 4, rotor 5 is scraped cyclone sheet 6, blade groove 7, pump case 8, air outlet 9, suction port 10, rear end cover 12, oil sealing 13, fan 14, fan guard 15.
Described forward and backward end cap 1,12 is offered eccentric opening.It is two with air outlet 9 that described suction port 10 is one.This vacuum pump also comprises outer suction formula fan 14, and fan 14 is connected on the rotor shaft core 3, is located at outside the pump case 8; On fan 14, also be covered with fan casing 15.Described rotor shaft core does not connect fan one end and is provided with retainingf key 4, is used to connect drive motor.
Pump case is the spheroidal graphite cast iron material, has a suction port and two relief openings, and pump chamber is the garden cylindricality, scrapes in inside; Cast-iron rotor is the spheroidal graphite cast iron material, and the rotor shaft core is a steel, when cast rotor, steel rotor shaft core is preset in the mould, after the casting, and completely one in rotor and rotor shaft core, toughness and wear resistance when such structure has guaranteed the rotor high-speed running, rotor shaft core two ends rigid bearing; On average offer four on the rotor and scrape the cyclone film trap, the blade groove is scraped light through broaching tool and handled, and scraping the cyclone sheet can throw away and reset smoothly, and scraping the cyclone sheet is the cotton material of iron, and is wear-resisting, thermal expansion is little; Front and rear cover is the spheroidal graphite cast iron material, offers eccentric opening, is fixed in the pump case two ends with Ф 8mm screw rod; Outer suction formula fans can be fixed on the rotor shaft core, and fan casing covers on the fans, is fixed on the pump case.
When the utility model was milked vacuum pump work, rotating shaft 3 was done at a high speed by external motoring and is rotated counterclockwise, and rotor rotates with speed on bearing, and the blade groove is in company with rotation.The blade groove turns to following time, scrapes the cyclone sheet and is thrown away fully, when the blade groove turns to, scrapes the cyclone sheet and is resetted fully, throws away fully to forward to and carries out exhaust when resetting fully, resets fully to forward to and carries out air inlet when throwing away fully.When rotor moves continuously, finish exhaust, air inlet continuously, continue to form and stablize vacuum, continue to offer the consumption of milking, two air outlet holes help smooth exhaust.Because of rotor 5, pump case 8 all adopt the spheroidal graphite cast iron material very wear-resisting, smooth because of scraping cyclone film trap groove face, the cotton blade of iron is wear-resisting, thermal expansion is little, blade can throw away and reset smoothly during pump work, and when rotating shaft was rotated in addition, fan was followed rotation, help heat radiation, vacuum pump can extremely not heat up, so rotor can locking, and vacuum pump stably provides big rate of air sucked in required milking vacuum.
