Description
Technical field
The utility model relates to coal mine roadway engineering slurry injection technique field, especially a kind of plunger hand mud pumping cylinder.
Background technique
In mortar depositing construction process, plunger hand slurry pump, as a kind of mini-plant of conveying cement slurry, is used widely because it is flexible, convenient.Existing plunger type pumping cylinder is that mast connects piston, and seal between piston and cylinder body, piston moves reciprocatingly under the drive of mast, and inner chamber of cylinder block forms volume-variation, and fed sheet of a media, seal ring is wherein arranged on piston and seals.Cement slurry is because of its thickness, and easily condensation forms particle, all weares and teares comparatively large, make plunger hand slurry pump amount of maintenance large to the seal ring of piston and cylinder body, and seal ring, plunger cylinder cycle in working life are short.
Summary of the invention
In order to overcome the deficiency that prior art exists, the utility model provides a kind of plunger hand mud pumping cylinder.Manual slurry pump sealing column stopper rod one place of this structure, compresses regulating nut press seal circle with one, compensates the wearing and tearing of plunger and seal ring, maintain reliable sealing.Drastically reduce the area the amount of maintenance of slurry pump, improve working life; The seal ring of damage can be changed quickly and easily.
The utility model solves the technological scheme that the deficiencies in the prior art take, comprise cylinder body, adjusting nut, seal ring, plunger, wherein, described seal ring is V-shaped seal ring, the external diameter of at least four described V-shaped seal rings coordinates with the inner chamber of cylinder body and seam, described internal diameter of the seal ring coordinates with plunger outer diameter, and described cylinder body is threaded adjusting nut, and the lower end of described adjusting nut coordinates with described seal ring and compresses;
The internal diameter of described inferior part of the cylinder block is less than upper inner diameter, has the annular groove coordinated with seal ring in the internal diameter on described top, and the internal diameter on the top of described cylinder body has the screw thread coordinated with adjusting nut;
The external diameter of described adjusting nut has screw thread, and the external diameter of described adjusting nut and seal ring abutting end is less than the external diameter of screw section;
Described plunger is cylinder type, described plunger has the hinging hole coordinated with slurry pump depression bar.
The beneficial effects of the utility model are: the external diameter of at least four V-shaped seal rings coordinates with the inner chamber of cylinder body and seam, internal diameter of the seal ring coordinates with plunger outer diameter, cylinder body is threaded adjusting nut, the lower end of adjusting nut coordinates the structural design compressed with seal ring, plunger does not rub with cylinder diameter, improve the reliability of sealing, simultaneously the internal diameter of seal ring and adjusting nut internal diameter coordinate the guiding function had plunger with plunger outer diameter, and be easy to change seal ring, the compacted regulating nut of seal ring compresses, regulating nut can compensate the wearing and tearing between plunger rod and seal ring, ensure effective sealing at any time, reduce amount of maintenance, seal ring not with piston cylinder inner diameter seal, reduce the machining accuracy of warp in piston cylinder, thus reduce manufacture cost.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model structural drawing.
Embodiment
Embodiment of the present utility model is, with reference to Fig. 1, comprise cylinder body 5, adjusting nut 3, seal ring 4, plunger 2, wherein, described seal ring 4 is V-shaped seal ring, and the external diameter of described at least four V-shaped seal rings 4 coordinates with the inner chamber of cylinder body 5 and seam, described seal ring 4 internal diameter and plunger 2 major diameter fit, described cylinder body 5 is threaded adjusting nut 3, and the lower end of described adjusting nut 3 coordinates with described seal ring 4 and compresses;
The internal diameter of described cylinder body 5 bottom is less than upper inner diameter, has the annular groove of joining 4 conjunctions with seal ring in the internal diameter on described top, and the internal diameter on the top of described cylinder body 5 has the screw thread coordinated with adjusting nut 3;
The external diameter of described adjusting nut 3 has screw thread, and described adjusting nut 3 and the external diameter of seal ring 4 abutting end are less than the external diameter of screw section;
Described plunger 2 is cylinder type, described plunger 2 there is the hinging hole 1 coordinated with slurry pump depression bar, the working principle of described plunger hand mud pumping cylinder is, when seal ring 4 weares and teares, screw adjusting nut 3, at this moment the gap of rising between compensation sealing circle 4 and plunger 2 external diameter pressed by seal ring 4 by adjusting nut 3, when the wearing clearance of seal ring 4 is excessive or damage, screw off adjusting nut 3, extract plunger 2 out, seal ring 4 can be taken out, after changing new seal ring, load onto plunger 2, screw adjusting nut 3, when operating, lift the depression bar in slurry pump, at this moment plunger 2 is upwards twitched with seal ring 4 internal diameter and adjusting nut 3 minor diameter fit, cylinder body 5 inner chamber of seal ring less than 4 forms vacuum, the slurry outlet that mud is arranged from cylinder body 5 bottom enters this inner chamber, when press down in slurry pump depression bar time, press plunger 2 descending, the slurry outlet arranged from cylinder body 5 bottom by mud extrudes, repeat above action, working surface can be pumped slurry into continuously.
