Abstract

The utility model relates to a lubrication pump for a wind power generation gear case, which comprises a pump body, a lining, a driving screw, a driven screw, a bearing and a seal and is characterized in that the pump body and the lining are integrally made, the driving screw and the driven screw are installed in the pump body, a front cover and a stuffing box are arranged at one end of the pump body and connected with the pump body through a fastening piece, a rotatable back cover is installed at the other end of the pump body, the seal is arranged on the outer side of the bearing, and an oil return hole communicated with a seal cavity of the pump body is arranged on the pump body. The lubrication pump for the wind power generation gear case has the advantages of being compact in structure, good in bearing sealing, capable of lubricating through a transmission medium and free of maintenance. The rotatable back cover of the lubrication pump is easy to assemble and disassemble, so that the lubrication pump is particularly suitable for the wind power generation gear case in severe environment and narrow space.

Description

Wind power generation gear case is used lubricating pump
Technical field
The utility model belongs to industrial pump and makes the field, particularly designs a kind of wind power generation gear case and uses lubricating pump.
Background technique
Three screw pump is as the power source of liquid, and extensively installation is matched in all kinds of lubrication statioies, hydraulic system and the various technology cooling system, and it is multi-field to be applied to boats and ships, metallurgy, iron and steel, petrochemical industry, electric power and machining etc.Use for many years facts have proved, three screw pump all has significant advance than existing other positive displacement pump in economic benefit, delivery quality, running life and maintaining etc. aspect many.Three screw pump of the prior art generally is to be used to carry lubricant oil, because the lubricity of lubricant oil is good, can between screw rod and lining, form good oil film, has guaranteed the working life of pump.At present; Many wind power generation gear case equipment need lubricate; Therefore but because wind power generation gear case equipment environment of living in is abominable and the space is narrow and small, need the lubricating pump compact structure, volume is little; Good airproof performance and need not maintenance and maintenance, and the lubricating pump of said structure can't satisfy the requirement of wind power generation gear case equipment to lubricant pump.
Summary of the invention
The wind power generation gear case that the utility model provides a kind of compact structure for solving the technical problem that exists in the known technology, be convenient to installing/dismounting and maintenance and Maintenance free maintenance is used lubricating pump.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: wind power generation gear case is used lubricating pump; Comprise the pump housing, lining, initiatively screw rod, driven screw rod, bearing and sealing; It is characterized in that: the said pump housing and lining are made as integrative-structure, and initiatively screw rod and driven screw rod are installed in the said pump housing, are provided with protecgulum and Stuffing box at the pump housing one end; Said protecgulum is connected with the pump housing through fastening piece with Stuffing box; The said pump housing the other end is equipped with rotatable bonnet, and the said bearing outside is provided with sealing, on the pump housing, is provided with the spill port that is communicated with pump housing Seal cage.
The utility model can also adopt following technological scheme:
Said bonnet is connected with the pump housing through four bolts that are uniformly distributed with, and structure can be revolved arbitrarily and turn 90 degrees, i.e. the import of the pump housing can have four kinds of relative positions with outlet.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Be about to the pump housing and lining and be made as integrative-structure; Be provided with sealing in the bearing outside, and rotatable bonnet be installed, so not only can make the lubricating pump compact structure at the pump housing the other end; Bearing seal property is good and can be lubricated through fed sheet of a media; Avoid maintaining, the rotatable four direction of lubricating pump bonnet is convenient to installation and removal simultaneously, uses so this lubricating pump is particularly suitable for the wind power generation gear case equipment that environment is abominable and the space is narrow and small.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1, the pump housing; 2, bonnet; 3, active screw rod; 4, driven screw rod; 5, protecgulum; 6, Stuffing box; 7, balance set; 8, bearing; 9, mechanical seal; 10, spill port; 11 bolts.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, wind power generation gear case is used lubricating pump, comprises the pump housing 1, lining, active screw rod 3, driven screw rod 4 and is installed in bearing 8 and the mechanical seal 9 on the pump main shaft.The said pump housing 1 is made as integrative-structure with lining, and initiatively screw rod 3, driven screw rod 4 and balance set 7 are installed in the pump housing, is provided with protecgulum 5 and Stuffing box 6 at the front end of the pump housing, and said protecgulum is connected with the pump housing through fastening piece with Stuffing box to be fixed.Rotatable bonnet is equipped with in said pump housing rear end; Said bonnet 2 (also being the import of pump) is connected with the pump housing through four bolts that are uniformly distributed with 11; Structure can be revolved arbitrarily and turn 90 degrees, i.e. the import of the pump housing can have four kinds of relative positions with outlet: one of which is that pump inlet and outlet are in same direction; Its two, be to see that from the pump shaft end right side advances out; Its three, be to see that from the pump shaft end left side advances out; Its four, go out on advancing under being.Said bearing 8 outsides are provided with mechanical seal 9, on the pump housing, also are provided with the spill port 10 that is communicated with pump housing Seal cage, and the oil in the Seal cage is got back to suction chamber through spill port.This lubricating pump compact structure, easy installation and removal, the maintenance of bearing Maintenance free.
