Abstract
The utility model discloses a high-pressure water pump, transforming the rotating movement of an input shaft into the reciprocating movement of a plunger in a cylinder body through a swash plate, a rocking plate and a connecting rod. An insert block arranged on the end plane of the rocking plate and each revolving bearing element is made of water-lubricating material. A limiting valve is arranged on the centerline of the cylinder body. Consequently, the high-pressure water pump requires no oil for lubrication. The utility model has the advantages of compact structure and high operational reliability.
Description
The utility model relates to a kind of plunger type high-pressure water pump.
Existing various axial piston liquid pump, 7GB-4.5/160 type water pump as the production of Chengdu, Sichuan coal mine machinery factory, because of its pivoting support and rotatablely move and all adopt rolling bearing to reciprocating conversion, wherein pivoting support adopts radial ball bearing, and rotatablely move to reciprocating conversion, then realize by bent axle and one group of thrust-bearing, because it is lubricated that these bearings need with mineral oil, so when pump is working medium with water, just must be to needing zero of lubricating condition, parts are taked tight quarantine measures, make the pump structure complexity, volume increases, cost is higher.
The purpose of this utility model provide a kind of simple in structure, volume is less, need not the axial plunger type high voltage water pump with oil lubrication.
High-pressure water pump of the present utility model is by swash plate and shaking tray and connecting rod, and rotatablely moving of input shaft is converted into the to-and-fro motion of plunger in cylinder body.Be characterized on the end face of shaking tray, being equipped with one group with inserting that the water lubrication material is made, and the water lubriation material is made the pivoting support element of pump.Like this, water pump just need not to use oil lubrication, and therefore pump structure is simplified, and functional reliability also has raising.
Another characteristics are the elastic force that utilizes retracting spring, a pressure-limit valve are set, compact structure on the cylinder center line of pump.
Advantage of the present utility model because of the equal water lubriation material of its pivoting support element is made, so need not to use oil lubrication, makes that this pump structure is simple, volume is less, manufacturing is easy to use.
Fig. 1, water lubrication axial plunger type high voltage water pump.
In the embodiment in figure 1, swash plate 2 is converted into the to-and-fro motion of plunger 6 in cylinder body 7 by shaking tray 4 and connecting rod 5 with rotatablely moving of input shaft 1.What be equipped with on the end face of shaking tray 4 that the water lubrication material makes inserts 3.Simultaneously, each pivoting support element 14,15,16 of input shaft 1, swash plate 2 also all adopts the water lubrication material.
Water enters housing 12 by hole 13, and each pivoting support element 14,15,16 of first cooling and lubricating and insert 3 cools off cylinder body 7 then, is entered the inner chamber of plunger 6 at last by liquid sucting valve 11, discharges from liquid discharging valve 10 again.
Establish a pressure-limit valve 9 on the center line of cylinder body 7, spring 8 is the pressure limiting spring of pressure-limit valve 9, is again the retracting spring that the backhaul impacting force is provided for water pump.
Claims (2)
1, a kind of water lubrication axial plunger type high voltage water pump comprises input shaft, swash plate, shaking tray, connecting rod, plunger, cylinder body, liquid sucting valve, liquid discharging valve, pressure-limit valve, it is characterized in that: the end face at shaking tray (4) is equipped with one group of insert (3) made from the water lubrication material, simultaneously, each pivoting support element (14) of pump, (15), (16) equal water lubriation material are made.
2, high-pressure water pump as claimed in claim 1 is characterized in that: be provided with pressure-limit valve (9) on the center line of cylinder body (7), spring (8) is the pressure limiting spring of pressure-limit valve (9), is again the retracting spring that the backhaul impacting force is provided for water pump.
