Description
Technical field
The utility model is related to filling machine equipment technical field, specially a kind of wear-resisting metering pump of bottle placer.
Background technology
Existing disc type auto-filling end sealing machine is when carrying out filling using Reciprocating Metering Pump when carrying out filling
It is quantitative, long-term reciprocal operation of the piston region when bottle placer works, the pump housing and piston generally use metal of the prior art
Material is made through thermo-chemical treatment, piston bush can be caused quickly to wear in prolonged reciprocal operation, be easy to happen leakage,
Measuring accuracy is caused to decline.
Invention content
For in the prior art the shortcomings that, the purpose of this utility model is that being improved to existing metering pump, provide one
The kind wear-resisting metering pump of bottle placer, piston bush are made of ceramic material, have high finish and wearability, with the cooperation of plastics inner sleeve
The wearability for improving both piston bush and plastics inner sleeve on the whole afterwards solves to improve the service life of metering pump
The problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions：A kind of wear-resisting metering pump of bottle placer, including pump
Body 5,5 top of the pump housing are equipped with feed inlet 7 and discharge port 6, and the feed inlet 7 and discharge port 6 are arranged symmetrically, the pump housing 5
Lower inner wall fixing sleeve is equipped with plastic sheath 4, and 4 inner wall of the plastic sheath, which is slidably matched, is arranged with piston bush 3, and the piston bush 3 is solid
Dingan County is mounted in 2 upper end of piston rod, and the piston bush 3 is ceramic material, and 2 lower end of the piston rod is hinged with link block 1.
Compared with prior art, the beneficial effects of the utility model are as follows：
The wear-resisting metering pump piston bush of this bottle placer is made of ceramic material, has high finish and wearability, with plastics
The wearability for improving both piston bush and plastics inner sleeve after inner sleeve cooperation on the whole, improves the service life of metering pump, protects
The precision of metering pump is held.
Description of the drawings
Fig. 1 is the utility model stereogram.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of wear-resisting metering pump of bottle placer, including the pump housing 5,5 top of the pump housing are equipped with feed inlet 7 and discharge port
6, feed inlet 7 and discharge port 6 are arranged symmetrically, and 5 lower inner wall fixing sleeve of the pump housing is equipped with plastic sheath 4, and 4 inner wall of plastic sheath is slidably matched
It is arranged with piston bush 3, piston bush 3 is fixedly mounted on 2 upper end of piston rod, and piston bush 3 is ceramic material, 2 lower end of piston rod
It is hinged with link block 1 and receives the motive force from filling mechanism of ocean (not shown), drive piston rod 2 to move back and forth, pass through
Feed inlet 7 and discharge port 6 complete the quantitative suction and discharge of liquid charging.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
