Abstract
The utility model provides a suction arrangement of a diaphragm pump type dynamic sprayer, comprising a suction cylinder and a piston. The piston is positioned in the suction cylinder; the peripheral surface of the piston is provided with an annular notch; an opening expansion ring having the external tension is arranged in the annular notch; the outer margin of the expansion is closely adhered to the inner wall of the suction cylinder. The suction arrangement of a diaphragm pump type dynamic sprayer can keep the suction force of the suction device by utilizing the elasticity of the expansion ring; the suction arrangement of a diaphragm pump type dynamic sprayer has simple structure, and can simplify the process, reduces the component precision and the cost when fabricating; the normal operation of the diaphragm pump is ensured and the service life is prolonged.
Description
Technical field
The utility model belongs to a kind of motor atomizer, particularly the suction device of membrane pump formula motor atomizer.
Background technology
Agricultural and industry of planting forest or fruit tress are generally used membrane pump formula motor atomizer in producing at present, and its suction device mainly is made of suction cylinder and piston.Because the side face of piston and the contact area of the suction inside wall of cylinder are big, so need leave bigger gap between the two, add owing to piston moves back and forth the wearing and tearing between the two that cause continually, cause the gap increase between the piston and the suction inside wall of cylinder and influence its operate as normal, obviously shortened service life, even appeared at and use after very short time with regard to inoperable phenomenon.
Summary of the invention
The purpose of this utility model just provides a kind of suction device of membrane pump formula motor atomizer, influence its operate as normal greatly with the fit clearance that solves suction cylinder that prior art exists and piston, service life is short, in addition after using very short time with regard to inoperable problem.
The technical solution of the utility model is: comprise suction cylinder and piston, piston is positioned at the suction cylinder, is provided with annular groove at the side face of described piston, and the opening of the tension force ring that rises is housed in this annular groove outside having, and this outer rim that rises by ring is close to the suction inside wall of cylinder.
The described opened gap that rises by ring is 0.05～0.2 millimeter; The ring that rises is 0.04～0.06 millimeter with the gap of annular groove side.
The rise elastic force of ring of the utility model utilization can keep the suction of suction device for a long time, and is simple in structure, can simplify technology during manufacturing, reduces other part precision, reduces cost.Guarantee the membrane pump normal operation, prolonged service life greatly.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of the utility model suction cylinder and piston;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises suction cylinder 1 and piston 2, and piston 2 is positioned at suction cylinder 1, is provided with annular groove at the side face of described piston 2, the opening of the tension force ring 3 that rises is housed in this annular groove outside having, and this outer rim that rises by ring 3 is close to the inwall of suction cylinder 1.The rise gap of ring 3 opening 4 is 0.05～0.2 millimeter; The ring 3 that rises is 0.04～0.06 millimeter with the gap of annular groove side.During installation, the dimensional contraction of the ring 3 that will rise is the internal diameter size of suction cylinder 1, can pushes in the suction cylinder 1.After the installation, the cylindrical of the ring 3 that rises is close to the inwall of suction cylinder 1.Ring 3 the counterpart gap of rising has only 0.1 millimeter, the ring 3 that rises is 0.04～0.06 millimeter with the side clearance of piston 2 annular grooves, dwindled the gap of piston 2 greatly with suction cylinder 1, and rely on the elastic force of the ring 3 that rises, can remedy the wearing and tearing between its outer rim and the suction inside wall of cylinder at any time, can keep suction for a long time, receive that suction is strong, the effect of life-span multiplication.
Claims (2)
1, a kind of suction device of membrane pump formula motor atomizer, comprise suction cylinder and piston, piston is positioned at the suction cylinder, it is characterized in that: the side face at described piston is provided with annular groove, the opening of the tension force ring that rises is housed in this annular groove outside having, and this outer rim that rises by ring is close to the suction inside wall of cylinder.
2, the suction device of membrane pump formula motor atomizer according to claim 1 is characterized in that: the described opened gap that rises by ring is 0.05～0.2 millimeter; The ring that rises is to be 0.04～0.06 millimeter with the gap of annular groove side.
