Abstract
The utility model provides a high-pressure airless sprayer which comprises a lower pump body component, a pump body, a plunger component, a plunger pump case, a seal-ring locking sleeve and a pump-body locking nut; the lower pump body component is connected onto the lower end of the pump body; the plunger component is arranged in the pump body; the plunger pump case is connected onto the upper end of the pump body; the end part of the plunger pump case is locked by the pump-body locking nut; and the seal-ring locking sleeve is connected at the top end of the pump body through screw threads. According to the high-pressure airless sprayer provided by the utility model, the rotation of the pump body is limited by the pump-body locking nut, and the seal-ring locking sleeve is connected onto the pump body through the screw threads, so that the axiality between the pump body and the seal-ring locking sleeve is high.
Description
Technical field
The utility model relates to the technical field of spray gun, particularly a kind of high pressure airless spray equipment.
Background technology
Airless spraying is a spraying method than the advanced person, and it adopts booster pump that coating is increased to high pressure (wirking pressure 60-300kg/cm2), and through very thin spray orifice ejection, it is fan-shaped vaporific that coating is formed.When the large-scale plate of spray, can cross 3-5M3/min, and can spray thicker coating; Because entrained air not in the coating; And higher coating transmission efficiency and production efficiency, thereby form fine and close coating at body of wall and metal surface, make no gas blowout tell surface quality and significantly be superior to aerial spraying.
Existing high pressure airless spray equipment, the pump housing, sealing ring lock sleeve are through being threaded on the pump case, and its end seals by sealing ring, and all there is screw thread at pump case two, and axiality has relatively high expectations, and difficulty of processing is big, and the pump housing and sealing ring lock sleeve axiality are low.
In view of this, it is high that the utility model embodiment has proposed a kind of axiality, and be prone to the high pressure airless spray equipment of processing.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model embodiment realizes through following technical scheme:
The high pressure airless spray equipment that the utility model provides; Comprise lower pump body assembly, the pump housing, plunger assembly, plunger pump case, sealing ring lock sleeve and pump housing locking nut; Said lower pump body assembly is connected the lower end of the pump housing, and said plunger assembly is installed in the pump housing, and said plunger pump case is connected the upper end of the pump housing; The end of said plunger pump case is by pump housing locking nut and tight, and said sealing ring lock sleeve is through being threaded in pump housing top.
Preferably, adopt hole axle ways of connecting between the said plunger pump case and the pump housing.
Preferably, seal by sealing ring on backup ring, the pump housing on sealing ring, the pump housing between the said plunger pump case and the pump housing.
Preferably, the sealing ring locking nut is installed in the said sealing ring lock sleeve.
Preferably, said sealing ring locking nut opening part is installed dust cap.
Preferably, seal by piston rod v-ring assembly between said sealing ring lock sleeve and the plunger assembly.
The high pressure airless spray equipment that the utility model provides, the pump housing be by pump housing locking nut limit rotation, and the sealing ring lock sleeve is through being threaded on the pump housing, so the axiality between the pump housing and the sealing ring lock sleeve is high.
Description of drawings
Fig. 1 is the overall sectional sketch map of the utility model high pressure airless spray equipment.
The specific embodiment
The utility model provides a kind of high pressure airless spray equipment.Said high pressure airless spray equipment comprises lower pump body assembly, the pump housing, plunger assembly, plunger pump case, sealing ring lock sleeve and pump housing locking nut; Said lower pump body assembly is connected the lower end of the pump housing; Said plunger assembly is installed in the pump housing; Said plunger pump case is connected the upper end of the pump housing, and the end of said plunger pump case is by pump housing locking nut and tight, and said sealing ring lock sleeve is through being threaded in pump housing top.
Further describe below in conjunction with specific embodiment.
Please consult Fig. 1 in the lump, be the overall sectional sketch map of the utility model high pressure airless spray equipment.
High pressure airless spray equipment mainly comprises on lower pump body assembly 1, the pump housing 2, plunger assembly 3, sealing ring 4, plunger pump case 5, locking nut sealing ring 6, piston rod v-ring assembly 7, sealing ring lock sleeve 8, sealing ring locking nut 9, dust cap 10, pump housing locking nut 11, the pump housing sealing ring 13 on backup ring 12, the pump housing.
Said lower pump body assembly 1 is connected the lower end of the pump housing 2, connects through screw thread.
Said plunger assembly 3 is installed in the pump housing 2.
Said plunger pump case 5 is connected the upper end of the pump housing 2, adopts hole axle ways of connecting between the said plunger pump case 5 and the pump housing 2.
The rotation of the pump housing 2 has been limited by pump housing locking nut 11 and tight in the end of said plunger pump case 5, and said sealing ring lock sleeve 8 is through being threaded in the pump housing 2 tops, so the height of the axiality between the pump housing 2 and the sealing ring lock sleeve 8.
Seal by sealing ring 13 on backup ring 12, the pump housing on sealing ring 4, the pump housing between the said plunger pump case 5 and the pump housing 2.
Said sealing ring locking nut 9 is installed in the sealing ring lock sleeve 8.
Said dust cap 10 is installed in sealing ring locking nut 9 opening parts.
Seal by piston rod v-ring assembly 7 between said sealing ring lock sleeve 8 and the plunger assembly 5.
In sum, the high pressure airless spray equipment that the utility model embodiment is provided, the pump housing be by pump housing locking nut limit rotation, and the sealing ring lock sleeve is through being threaded on the pump housing, so the axiality between the pump housing and the sealing ring lock sleeve is high.
More than high pressure airless spray equipment that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the technical scheme that the utility model discloses; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
