By adopting the structure, the high-pressure swash-plate pump overcomes the deficiencies of complicated structure and short service life, and has the advantages of simple and reasonable structure, high working efficiency, convenient maintenance, long service life and the like.
Description
Technical field
The utility model relates to the high pressure swash plate pump of a kind of pump body of high-pressure cleaning machine, particularly a kind of improvement.
Background technique
Pump body of high-pressure cleaning machine is various in style in the market, mainly based on single plunger and multicolumn plug, the multicolumn plug structure since characteristics such as pressure height, flow are big, pressure stability begun progressively to replace the single plunger structure and become the market leading products.The multicolumn plug structure comprises pump head, a plurality of uniform plunger, transmission case body, stationary axle, driving gear, swash plate, the inclined-plane of swash plate is provided with plane bearing, power drives the swash plate rotation by driving gear during work, plane bearing on the swash plate promotes a plurality of plungers and does the high frequency to-and-fro motion, the water of water intake pressurizes in plunger cavity after go out water one-way valve to outlet pipe, sprays from nozzle by pressure regulator valve again.Said structure has the following disadvantages: the one, because plunger single-point on swash plate is exerted pressure, bear bigger axial force on the plane bearing, and the surface friction drag that plane bearing produces is big, causes plane bearing to damage easily, thereby has shortened working life; The 2nd, owing to be provided with stationary axle and driving gear in the casing, complex structure, big, the assembling inconvenience of volume.For this reason, many manufacturers, scientific research institutions and knowledgeable people have carried out the R and D of fruitful ground, but do not have rational product to emerge so far as yet.
Summary of the invention
In order to overcome the above-mentioned defective that existing pump body of high-pressure cleaning machine exists, the purpose of this utility model provides a kind of high pressure swash plate pump with simple and reasonable, high working efficiency, long service life.
The technological scheme that its technical problem that solves the utility model adopts, it comprises pump head, case lid, transmission case body, case lid is fixed on the transmission case body, pump head is fixedlyed connected with case lid, pump head is provided with a water intake and an outlet pipe, being provided with by the back thrust-bearing in the described transmission case body can counterrotating horizontal swash plate, and the inclined-plane of horizontal swash plate is provided with the forward thrust bearing, and the forward thrust bearing matches with plunger on being arranged on pump head and case lid.
Described pump head and case lid are provided with six plungers that are uniformly distributed along the circumference, be provided with a water inlet one-way valve in the plunger cavity of each plunger, each water inlet one-way valve links to each other with water intake, the outlet of each plunger is provided with out water one-way valve, each goes out water one-way valve and communicates with outlet pipe, be provided with retracting spring between each plunger and the case lid, each plunger is provided with water-sealed component.
Be connected with pressure regulator valve on the described outlet pipe.
Described case lid is provided with the oil sealing with plunger seal.
Described transmission case body is provided with the oil sealing with horizontal swash plate sealing.
After adopting said structure, the utility model has following advantage and effect: the one, owing to adopt the horizontal swash plate motion of the direct drive of external power, simplified middle transmission link, and simple and compact for structure, easy to assembly; The 2nd, the utility model is owing to adopt thrust-bearing, and the axial force that can bear plunger preferably makes bearing all come rotatablely moving of support level swash plate with the rolling friction of a contact, has improved the mechanical efficiency of product effectively; The 3rd, adopt 6 plungers, can improve the working efficiency of pump head greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, specific embodiments for the utility model high pressure swash plate pump, it comprises pump head 13, case lid 16, transmission case body 8, case lid 16 is fixed on the transmission case body 8 by bolt 17, pump head 13 is fixedlyed connected with case lid 16 by bolt 14, pump head 13 is provided with a water intake 11 and an outlet pipe 9, be connected with pressure regulator valve 1 on the described outlet pipe 9, being provided with by back thrust-bearing 6 in the described transmission case body 8 can counterrotating horizontal swash plate 7, the inclined-plane of horizontal swash plate 7 is provided with forward thrust bearing 5, and forward thrust bearing 5 matches with plunger 3 on being arranged on pump head 13 and case lid 16.Described pump head 13 and case lid 16 are provided with six plungers 3 that are uniformly distributed along the circumference, be provided with a water inlet one-way valve 10 in the plunger cavity of each plunger 3, each water inlet one-way valve 10 links to each other with water intake 11, the outlet of each plunger 3 is provided with out water one-way valve 2, each goes out water one-way valve 2 and communicates with outlet pipe 9, be provided with retracting spring 4 between each plunger 3 and the case lid 16, each plunger 3 is provided with water-sealed component 12.Described case lid 16 is provided with the oil sealing 15 with plunger 3 sealings.Described transmission case body 8 is provided with the oil sealing 18 with horizontal swash plate 7 sealings.
When external impetus drove horizontal swash plate 7, horizontal swash plate 7 drove forward thrust bearings 5 and rotates, and forward thrust bearing 5 drives six plungers 3 and moves back and forth.When plunger 3 is done motion away from water inlet one-way valve 10 under retracting spring 4 effect, produce negative pressure in the plunger cavity of pump head 13, the one-way valve 10 of intaking this moment is opened, and goes out water one-way valve 2 and closes, and water enters in the plunger cavity of pump head 13.When plunger 3 antiports, produce pressure in the plunger cavity of pump head 13, water inlet one-way valve 10 is closed, and goes out water one-way valve 2 and opens, water extrudes in the plunger cavity of pump head 13, through go out water one-way valve 2, pressure regulator valve 1 sprays from outlet nozzle.If the adjusting pressuring handle of rotation pressure regulator valve 1, the inner off-load flow of can regulate reaches the purpose that adjusts mouth pressure.
