Abstract
The utility model provides a supporting type double-screw pump which comprises a pump body, a driven screw, a driving screw, a packing seal, a lubrication box, a gear and a transmission box. The supporting type double-screw pump is characterized in that a conical roller bearing and a thrust ball bearing are arranged at the positions on the driven screw and the driving screw corresponding to the right end portion of the lubrication box. The supporting type double-screw pump has the advantages that when high-pressure high-viscosity media are conveyed, seizure does not occur between the driven screw and the driving screw, and accordingly the double-screw pump can run normally.
Description
Technical field: the utility model relates to the two screw pump that is used for line transportation high-voltage high-viscosity degree medium in a kind of commercial production, particularly a kind of supporting type two screw pump.
Background technique: the existing two screw pump that is used for line transportation high-voltage high-viscosity degree medium, referring to accompanying drawing 1, it mainly is made up of the pump housing 1, driven screw rod 2, active screw rod 3, packing seal 4, lubrication box 5, double-row angular contact bal bearing 6, gear 7, transmission case 8.In use there is following deficiency in this kind two screw pump: when carry be high-voltage high-viscosity degree medium the time, right screw rod appears easily and left screw rod is killed each other, make two screw pump normally not move.The appearance of this problem, its reason are, in carrying high-voltage high-viscosity degree medium process; Initiatively screw rod 3 all can receive a very big axial force with driven screw rod 2; And double-row angular contact bal bearing often holds and can't stand very big axial force, when axial force greatly when surpassing the axial force that double-row angular contact bal bearing bore, initiatively axial displacement can take place in screw rod 3 and 2 of driven screw rods; Asynchronous because of displacement, the situation that active screw rod 3 and driven screw rod 2 are killed each other then appears.
Summary of the invention: the purpose of the utility model is; To above-mentioned two screw pump when carrying high-voltage high-viscosity degree medium; Its initiatively screw rod and the easy appearance of driven screw rod kill each other, make the deficiency that two screw pump can not normally move, and propose a kind of when carrying high-voltage high-viscosity degree medium; Two screw pump driven screw rod can not occur and kill the supporting type two screw pump that can normally move each other with the active screw rod.
Can realize the purpose that this practicality is new through following technical proposals; A kind of supporting type two screw pump; Comprise the pump housing, driven screw rod, active screw rod, packing seal, lubrication box, gear, transmission case; It is characterized in that the corresponding part, right part with lubrication box on driven screw rod and active screw rod is provided with tapered roller bearing and thrust ball bearing.
The effect of the utility model is: when this pump is carried high-voltage high-viscosity degree medium; Can not kill each other between the driven screw rod of pump and the active screw rod; Two screw pump can normally be moved; This is that this pump has substituted double-row angular contact bal bearing of the prior art with tapered roller bearing and thrust ball bearing; They can well overcome pump and are in operation to driven screw rod and the axial force that initiatively screw rod produced, make driven screw rod and initiatively the gap between the screw rod keep normal, thereby can make pump keep normal operation.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Description of drawings:
Accompanying drawing 1 is the sectional structure chart of two screw pump in the existing technology.
Accompanying drawing 2 is the utility model sectional structure chart;
Embodiment:
Referring to accompanying drawing 2, a kind of supporting type two screw pump, it is made up of the pump housing 1, driven screw rod 2, active screw rod 3, packing seal 4, lubrication box 5, gear 7, transmission case 8, tapered roller bearing 9 and thrust ball bearing 10.Tapered roller bearing 9 and thrust ball bearing 10 are located on driven screw rod 2 and the screw rod 3 initiatively the corresponding part, right part with lubrication box.
