Description
Technical field
The invention belongs to dusting apparatus, particularly a kind of trilobal water-cooled Roots pump.
Background technique
At present, take place in the serious workshop at dust and gas, the equipment of dust suction and gas has multiple, and there is the little and unsettled defective of the speed of exhaust of high vacuum pressure lower pumping amount in the mechanical type vacuum pump, and roots blower and Roots pump are prone to the heat exchange phenomenon phenomenon that promptly heats up, and influence the working life of pump.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, the trilobal water-cooled Roots pump that a kind of pumping speed is big, do not have wearing and tearing, long service life is provided.
The technological scheme that technical solution problem of the present invention adopts is: trilobal water-cooled Roots pump comprises pump case, side cover one, side cover two, bearing, bearing cap one, two, three, four, the reinforced seal ring, the oil sealing plug screw, the left surface that is characterized in the side cover two on the left of pump case is fixed a gear housing, in gear housing, adorn driving gear and driven gear respectively on the rotor shaft one of parallel dress and the rotor shaft two, driving gear and driven gear are connected with a joggle, the axle sleeve two of band shoulder is housed on the left end head of rotor shaft one, dress gets rid of oiled-plate method on the shoulder of axle sleeve two, and fastening with thrust washer and locking nut; Establish trilobal rotor one and rotor two on rotor shaft one in pump case and the rotor shaft two respectively, trilobal rotor one and rotor two intermesh.
The invention has the beneficial effects as follows: mechanical pump such gas compression phenomenon and roots blower can not take place in the pump chamber of trilobal water-cooled Roots pump, the heat exchange phenomenon that Roots pump the occurs phenomenon that promptly heats up, can be used to aspirate various doing, wet material, also can inhale coercibility steam by axle, of many uses, the rotor surface of vacuum pump is a circular arc trilobal cylinder, has good geometrical symmetry, its rotating speed height, realize big pumping speed, rotor does not contact mutually with the pump case inner casing, rotor is worked under no state of wear, improved the working life of vacuum pump, coolant seal water can guarantee vacuum pump work at normal temperatures, reaches energy-saving effect.

Embodiment
Embodiment, with reference to accompanying drawing 1,2, parallel cartridge rotor axle 1 and rotor shaft 29 in the pump case 8 of trilobal water-cooled Roots pump, rotor shaft 1 and rotor shaft 29 are provided with intermeshing trilobal rotor one 13-1 and trilobal rotor two 9-1.Rotor shaft 1 and rotor shaft 29 two ends all are contained in side cover 1 and the side cover 25 with reinforced seal ring 7 and bearing 6.Dress dust-blocking ring 14 usefulness bearing caps 2 15 cappings on rotor shaft one 13 right-hand members, dress key 12 on rotor shaft one 13 right-hand member heads.In bearing cap one 11 cappings of rotor shaft 29 right-hand member heads, above side cover 1 and side cover 25, all establish oil nozzle 4, dress axle sleeve one 16 usefulness reinforced seal rings 7 and bearing cap 4 24 cappings on the rotor shaft 29 in side cover 25 left sides, the left end on rotor shaft 1 is equipped with axle sleeve one 16 usefulness reinforced seal rings 7 and bearing cap 3 17 cappings equally.Fixed gear fuel tank 2 on the left surface of side cover 25, on gear tank 2, establish oil sealing plug screw 1, dress driving gear 18 on rotor shaft one 13 left ends in gear tank 2, be connected dress axle sleeve 2 19 with driving gear 18 on rotor shaft one 13 left end heads, dress gets rid of oiled-plate method 20 and fastening with thrust washer 22 and locking nut 21 on axle sleeve 2 19 shoulders.At the left end dress of rotor shaft 29 and the driven gear 3 of driving gear 18 engagements.Above pump case 8, establish suction port 8-1, on pump case 8 downsides, establish relief opening 8-2.On the side of gear housing 2, establish oil level glass 23.
The working principle of trilobal water-cooled Roots pump is: have two trilobal rotors, one, two 13-1,9-1 to be vertically set on mutually on the rotor shaft one, 2 13,9 of pair of parallel in pump case 8, a pair of transmission is installed is 1: 1 intermeshing straight-tooth driving gear 18 and driven gear 3 and drive rotors in gear housing 2, do reverse each other rotatablely moving synchronously.Between rotor and pump case 8 inwalls, maintain the gap of 250 μ m, after pump chamber injects coolant seal water, because the high speed rotating of trilobal rotor one, two 13-1,9-1, make 8 of rotor and pump case produce the sealing moisture film, gas is drawn in the space of 8 of rotor and pump case from suction port 8-1, discharges through relief opening 8-2 again.Form vacuum in the suction side, and exhaust side communicates with atmosphere and taps into barometric pressure, because pump housing inside seals fully, so not compression and expansion in the pump chamber, when rotor is rotated further, outside gas excavationg pump housing 8, rotor and pump case 8 forms moisture films, also has cooling effect simultaneously playing seal action.
