Abstract
The utility model provides a novel pump for a sprayer. The utility model is characterized in that a sealed pump chamber is composed of a pump body [1], a pump cover [5], and O-shaped sealing rings [3] and [9], and the inner part of the sealed pump chamber is provided with a pump rotor which is compose of impellers [4] which are connected into together by keys [7], an axle sleeve [11], and nuts [6].
Description
The utility model belongs to centrifugal peripheral pump, the particularly head pressure sprayer pump below 1.5 MPas.
The sprayer pump of prior art all is reciprocating pump or diaphragm pump.
The purpose of this utility model provides a kind of centrifugal vortex type sprayer pump.Compare to reciprocating pump, the diaphragm pump of prior art, simple and reliable for structure, save cost.
The purpose of this utility model is achieved in that impeller connects with axle by key and axle sleeve, and connects firmly in the pump chamber of back formation at the pump housing and pump cover.By the adjustment pad between the pump housing and pump cover, guarantee that impeller has rational play gap in pump chamber, axle and axle sleeve pass the annular position of the pump housing, and an O-ring seals is arranged, together with the airtight pump chamber of the common formation of the O-ring seals between the pump housing, pump cover.At axle head one nut is arranged, the axial compression axle sleeve.
Accompanying drawing is a structure sectional view of the present utility model, in the accompanying drawings: 1: pump; 2: bolt; 3:O shape seal ring; 4: impeller; 5: pump cover; 6: nut; 7: key; 8: axle; 9:O shape seal ring; 10: adjust pad; 11: axle sleeve.
Below in conjunction with accompanying drawing, the utility model example is elaborated.On the circumference both ends of the surface of impeller ［ 4 ］, be shaped on radial blade 20-80 sheet, endoporus cooperates with axle sleeve ［ 11 ］, and axle sleeve ［ 11 ］ cooperates with axle ［ 8 ］, by key ［ 7 ］, makes impeller ［ 4 ］, axle sleeve ［ 11 ］ and axle ［ 8 ］ form key connecting.In the runner of the pump housing ［ 1 ］, in the matching gap that a cut water and impeller ［ 4 ］ cylindrical are arranged between suction port and the exhaust port between the 0.02-0.20 millimeter, the pump housing ［ 1 ］ pump cover ［ 5 ］ is connected by bolt ［ 2 ］, constitutes airtight pump chamber together with O-ring seals ［ 3 ］, ［ 9 ］.The axial clearance that pad ［ 10 ］ is adjusted the pump housing ［ 1 ］ and pump cover ［ 5 ］ connection back and impeller ［ 4 ］ remains between the 0.05-0.30 millimeter; Nut ［ 6 ］ axial compression axle sleeve ［ 11 ］.
Claims (3)
1, a kind of pump housing [1], pump cover [5], O-ring seals [3] of being installed in, connect by bolt [2] in the pump chamber of back formation, have axle [8], an impeller [4], axle sleeve [11], key [7] and constitute the sprayer pump of rotor jointly, it is characterized in that, be shaped on radial 20-80 sheet blade on the circumference both ends of the surface of impeller [4].
It is characterized in that according to claim 1 described sprayer pump that 2, the runner suction of pump case ［ 1 ］ and the radial clearance of cut water between the exhaust port and impeller ［ 4 ］ cylindrical are between the 0.02-0.20 millimeter.
3, it is characterized in that according to claim 1 described sprayer pump: between the pump housing ［ 1 ］ and pump cover ［ 5 ］, the inner chamber after adjustment by pad ［ 10 ］ and bolt ［ 2 ］ are fastening and the axial clearance of impeller ［ 4 ］ are between the 0.05-0.30 millimeter.
