Abstract
The utility model relates to a horizontal high-pressure double-screw pump. The double-screw pump comprises a pump and two mutually engaged screws, wherein a bearing seat and a ball bearing are arranged at the driving end of each screw; a bearing seat and a gear box are arranged at the non-driving end of each screw; a mechanical seal is arranged at two ends of each screw; and an adjusting ring is arranged between two bearings at the driving end of each screw. The double-screw pump is characterized in that a lubricating hole is formed on the upper part of each bearing seat, which corresponds to the back of the mechanical seal at the non-driving end; a discharge hole is formed on the lower part of each bearing seat; an oil injection hole is formed on each of the adjusting ring between the two bearings at each driving end and the corresponding position of each bearing seat; and an oil injection cup is arranged at the lubricating hole of each bearing seat. The utility model has the advantages that the working capability of the double-screw pump under a high-pressure working condition is greatly improved, so that a medium can be safely delivered under the condition of high pressure.
Description
Technical field
The utility model belongs to volume type screw pump technical field, particularly relates to a kind of horizontal high-pressure two screw pump.
Background technique
Two screw pump is a kind of positive displacement pump, has been widely used at present each industrial fields such as oil, chemical industry and boats and ships, is used for carrying various media.In actual applications, recent domestic market is more and more to the demand of high pressure two screw pump, and the viscosity of fed sheet of a media is also more and more lower.As water content also higher and viscosity be only the crude oil of 1 ~ 10cst, require flow 50m
3/ h, and discharge pressure is up to 6.3MPa, and therefore common two screw pump can't adapt to the high pressure operating mode of above-mentioned fed sheet of a media.
Summary of the invention
The utility model provides a kind of horizontal high-pressure two screw pump that is applicable to the conveying high-pressure medium for solving the technical problem that exists in known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
the horizontal high-pressure two screw pump, comprise the pump housing, two intermeshing screw rods in the pump housing are installed, the bolt rod driving end is equipped with bearing support and is used for the ball bearing of axially locating, screw rod anti-drive end installation shaft bearing and gear-box, be provided with mechanical seal at screw rod two ends, between two bearings of bolt rod driving end, adjustment ring is housed, it is characterized in that: top, the corresponding mechanical seal back position place of described bearing support has the lubrication hole for mechanical seal, the bottom is shaped with discharge orifice, be shaped with for the oil hole that bearing is lubricated on adjustment ring between two bearings of described drive end and bearing support relevant position, priming cup is equipped with at the lubrication hole place of described bearing support.
The utility model can also adopt following technological scheme:
Described priming cup adopts the needle valve priming cup.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely have lubrication hole on top, the corresponding mechanical seal back position place of bearing support, the bottom is shaped with discharge orifice, be shaped with for the oil hole that bearing is lubricated on the adjustment ring between two bearings of drive end and bearing support relevant position, priming cup is equipped with at the lubrication hole place of bearing support.When the horizontal high-pressure two screw pump is started working, at first annotate lubricant oil by priming cup in bearing support, and then turn on pump running, the change in color of regularly checking oil in priming cup, and when oil level is too low make-up oil.Increased substantially like this ability to work of two screw pump under the high pressure operating mode, made the medium can be in the situation that the carrying of high pressure safety.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, the horizontal high-pressure two screw pump, comprise the pump housing 1, two intermeshing screw rods 10 in the pump housing are installed, the bolt rod driving end is equipped with bearing support 2, roller bearing 3 and is used for the contact ball bearing 4 of axially locating, also be provided with lubricating cup 5 on the drive end axle bearing, can inject lubricating grease is that drive end bearing is lubricated.Described screw rod anti-drive end installation shaft bearing 2, roller bearing 3, gear-box 7 and gear 6.Be provided with mechanical seal 8 at screw rod two ends, between two bearings of bolt rod driving end, adjustment ring be housed.In the present embodiment, described mechanical seal is preferably mechanical sealing static ring, and top, the corresponding mechanical sealing static ring back position place of described bearing support has the lubrication hole 2-1 for the mechanical sealing static ring position, and the bottom is shaped with discharge orifice 2-2.Be shaped with for the oil hole 2-3 that bearing is lubricated on adjustment ring between two bearings of described drive end and bearing support relevant position, priming cup 9 is equipped with at the lubrication hole place of described bearing support.Described priming cup adopts the needle valve priming cup, and the needle valve priming cup can be the mechanical sealing static ring back side and is lubricated, and when mechanical seal leakage, can in time observe medium and enter the needle valve priming cup.
Working principle of the present utility model is:
When the horizontal high-pressure two screw pump is started working, at first annotate lubricant oil by the needle valve priming cup in bearing support, and then turn on pump running, the change in color of regularly checking oil in priming cup, and when oil level is too low make-up oil.Increased substantially like this ability to work of two screw pump under the high pressure operating mode, made the medium can be in the situation that the carrying of high pressure safety.
