Abstract
The utility model provides an energy-saving two-screw pump. The energy-saving two-screw pump comprises a rear cover box, a pump body, a driving screw, a driven screw, a lining, a sliding bearing, a front cover, a bearing pedestal, a bearing and a drive shaft, and is characterized in that the rear end parts of a friction wheel on the driving screw and a friction wheel on the driven screw are respectively provided with a bevel wheel; and the two bevel wheels are nested with each other. The energy-saving two-screw pump has the effects that 1, energy can be saved, the use cost is reduced, and 13-15% of electric energy can be saved in comparison with the conventional two-screw pump; and 2, the failure rate is low, the operation is stable, and the service life is long.
Description
Technical field: the utility model relates to and is used for the screw pump, particularly a kind of energy-saving two screw pump that pipeline is carried in a kind of industrial production.
Background technique: existing pipeline is carried and is generally used two screw pump, as shown in Figure 1, it mainly is made up of back top box 1, friction wheel 2, the pump housing 3, active screw rod 4, driven screw rod 5, lining 6, sliding bearing 7, protecgulum 8, bearing support 9, bearing 10, transmission shaft 11; In use, it has following deficiency: in the process of fed sheet of a media, initiatively the mutual chimeric spiral profile of screw rod and driven screw rod spiral shell can be subjected to very big resistance and serious abrasion, it not only directly influences flow also will consume bigger power of motor, makes pump not reach the usage requirement of operating mode and the working life that shortens pump.Cause the reason of this problem to be, the pump operation is to come the work of driven transmission screw rod by active screw spiral profile, and this kind of drive resistance is big, thereby will consume bigger power of motor, and the user cost height makes that also the working life of pump is short.
Summary of the invention: the purpose of this utility model is, the deficiency that in use exists at above-mentioned two screw pump, and propose that a kind of user cost is low, the energy-saving two screw pump of long service life.
Can realize the purpose that this practicality is new by following technical proposals, a kind of energy-saving two screw pump, comprise back top box, the pump housing, active screw rod, driven screw rod, lining, sliding bearing, protecgulum, bearing support, bearing, transmission shaft, it is characterized in that, the friction wheel that is located on the active screw rod is respectively established a helical gear with the rearward end that is located at the friction wheel on the driven screw rod, and is chimeric mutually between two helical gears.
Be located at the helical gear and the helical gear that is located at friction wheel rearward end on the driven screw rod of friction wheel rearward end on the active screw rod, the diameter ratio between them is 2: 3.
Effect of the present utility model is: 1, energy-conservation, user cost reduces, this because, the pump operation is to come the work of driven transmission screw rod by the helical gear on the active screw rod, like this, initiatively the spiral profile of screw rod and driven screw rod spiral shell just can not be subjected to abrasion, and its resistance also greatly reduces, and comparable existing two screw pump is saved 13～15% electric energy; 2, low, stable, the long service life of rate of fault, because helical gear can make initiatively that the spiral profile of screw rod and driven screw rod spiral shell can not be subjected to abrasion in this pump, so, can make that pump operation is stablized, low, the long service life of rate of fault.
The utility model will be further described below in conjunction with drawings and Examples.
Description of drawings:
Accompanying drawing 1 is two screw pump sectional structure chart of the prior art.
Accompanying drawing 2 is the utility model sectional structure chart.
Embodiment:
Referring to accompanying drawing 2, a kind of energy-saving two screw pump, it mainly is made up of back top box 1, helical gear 2, helical gear 21, friction wheel 3, friction wheel 31, the pump housing 4, active screw rod 5, driven screw rod 6, lining 7, sliding bearing 8, protecgulum 9, bearing support 10, bearing 11, transmission shaft 12.Initiatively screw rod 5 and driven screw rod 6 are located in the cavity of the pump housing 4.Transmission shaft 12 is connected with active screw rod 5.Lining 7 is located at screw rod 5 initiatively and driven screw rod is peripheral and the pump housing 4 between.Helical gear 2 and friction wheel 3 are located at the rear end of driven screw rod 6; Helical gear 21 is located at the initiatively rear end of screw rod 5 with friction wheel 31, and tiltedly word gear 2 and oblique 21 of word gears are mutual chimeric, and the diameter ratio between them is 2: 3.Sliding bearing 8 is located at the front end of driven screw rod 6.Protecgulum 9, bearing support 10, bearing 11 all are enclosed within on the transmission shaft 12; Protecgulum 9 is connected with the pump housing 4; Bearing support 10 is connected with protecgulum 9.
The operation procedure of this device is: transmission shaft 12 drives initiatively screw rod 5 rotations, and initiatively screw rod 5 drives driven screw rod 6 rotation operations by helical gear 21 and helical gear 2.
