Abstract
The utility model discloses an improved feed port puller which comprises a steel cylinder; an internal threaded hole is arranged at the outside end of the puller; a threaded push rod is installed inside the internal threaded hole; the outer walls of the inside end of the steel cylinder are connected through symmetrically arranged chains as well as a connecting flange arranged at the end face of the body of a mono-screw pump; and the outside end of a threaded rod inside the mono-screw pump extends into the steel cylinder. The improved feed port puller is simple in structure and can conveniently take out the feed port of the mono-screw pump. The improved feed port puller saves time and labor.
Description
Technical field
The utility model relates to a kind of improved charging aperture chest expander.
Background technology
Back rubber gets into charging aperture to the curved bar pump because of stator comes unstuck at present, and charging aperture, stator and rotor etc. can not got, and the pump house pipeline is many, and problems such as the narrow and small operation inconvenience in space are perplexing field engineering technical staff and oil recovery employee always.Become a hard nut to crack of cost waste.Also want a complete set of equipment of frequent change pump simultaneously, rate when influencing oil transportation causes the waste of human and material resources, resource.Unique technical method is to adopt the sparking ticket after burning burnt rubber, to take out at present; Charging aperture reduces through burning back Material Strength and surface smoothness, and the life-span reduces, and then need change a complete set of equipment of pump if need in time resume production; When operation, waste time and energy cost of idleness.
Summary of the invention
The purpose of the utility model is to provide a kind of improved charging aperture chest expander, and it is simple in structure, can take out the charging aperture of curved bar pump easily, and it is time saving and energy saving to use.
The purpose of the utility model is to realize like this; A kind of improved charging aperture chest expander; This instrument comprises that its outboard end has the steel cylinder of internal thread hole; A threaded mandrel is installed in the internal thread hole, and the chain through symmetric arrangement between the medial extremity periphery wall of steel cylinder links to each other with the adpting flange of curved bar pump pump housing end face, and the threaded rod outboard end in the curved bar pump extends in the steel cylinder.
When the utility model uses, rotate threaded mandrel, just can the threaded rod of curved bar pump be ejected the pump housing; Accomplish the essential step of pump housing maintenance, can take out the charging aperture of curved bar pump then easily, need not to re-use mode dismounting and change charging apertures such as sparking ticket burning; Greatly reduce working strength of workers; Reduced the enterprise production cost, the utility model is simple in structure, and it is time saving and energy saving to use.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of improved charging aperture chest expander; As shown in Figure 1; This instrument comprises that its outboard end has the steel cylinder 1 of internal thread hole 3; 3 are installed with a threaded mandrel 2 in the internal thread hole, and the chain 4 through symmetric arrangement between the medial extremity periphery wall of steel cylinder 1 links to each other with the adpting flange of curved bar pump 5 pump housing end faces, and threaded rod 6 outboard ends in the curved bar pump 5 extend in the steel cylinder 1.During use, rotate threaded mandrel 2, just can the threaded rod of curved bar pump be ejected the pump housing, accomplished the essential step of pump housing maintenance, can take out the charging aperture of curved bar pump then easily through staff or motor,
