Abstract
The utility model technically aims to provide a plunger slurry pump with a quick-replaceable plunger piston structure to solve the deficiency of the conventional plunger piston replacement manner. Through structural innovation, the utility model provides the plunger piston structure with quicker and much more convenient replacement, so as to improve the drilling efficiency and achieve the multipurpose function as required by the development tendency. A hydraulic cylinder of the plunger slurry pump is directly positioned on a machine frame, and the entire plunger piston assembly is positioned in the hydraulic cylinder and a cylinder sleeve via positioning sleeves and is locked by buttress threads of the cylinder sleeve. The utility model has the following advantages: through improving the positioning manner of the hydraulic cylinder, the cylinder sleeve and the machine frame, the purpose of quick replacement is realized, the entire plunger piston assembly can be removed from the front cavity of the machine frame quickly and conveniently; and coarse pitch buttress threads can be removed quickly and locked reliably.
Description
Technical field
The utility model technology relates to the conveying equipment for fluid substances technical field, special mud pump with plunger quick change piston structure.
Background technique
Technological processes such as each elephant drilling well both at home and abroad, well workover, well-flushing, pressure break need to use a large amount of mud pump with plunger.Plunger is the key component of mud pump with plunger, also is easily damaged parts, along with the development of drilling technology, the quick replacing of easily damaged parts plunger is had higher requirement.
In order to adapt to the changeable drilling operating mode of each elephant, a tractor serves several purposes has become development trend, and a kind of type is equipped with the plurality of specifications plunger and also uses and give birth to the pump type that satisfies a plurality of working condition requirements.In this case, the quick change piston structure has also become a kind of development trend.Be the supporting mud pump with plunger of oil field drilling technological process,, all should adopt rapid-changing structure to the fluid end plunger as far as possible for improving drilling efficient, reducing operating cost.
At present, oil field drilling both at home and abroad is widely used with mud pump with plunger to be the structural type that a kind of pump type is equipped with a kind of plunger, plungers pump plunger combination unloading process is as shown in Figure 1: dismounting cutting ferrule 1, the gland nut 7 of outwarding winding, disassemble blind nut 9, pull down cylinder cap 8 with the cylinder cap extractor, again plunger combination 2 is pulled out in the hole of dress cylinder cap.Its deficiency is: changing plunger wastes time and energy, and a kind of pump type only is applicable to a kind of operating mode, the operating cost height.
Summary of the invention
The purpose of the utility model technology is a kind of mud pump with plunger with quick change piston structure of design, deficiency at existing plunger substitute mode, upgrade from structure, release the piston structure of more quick and easy replacing, to improve drilling efficient, the development trend requirement of simultaneous adaptation a tractor serves several purposes.
Specifically, have the mud pump with plunger of quick change piston structure, its fluid cylinder is directly located on frame, and whole plunger combination is located in fluid cylinder and cylinder sleeve with setting sleeve and locked in fluid cylinder by the cylinder sleeve buttress thread.
The utility model advantage is: by improving fluid cylinder, cylinder sleeve and frame location pattern, realize quick-replaceable purpose, quick and easy the taking out from the frame ante-chamber of whole plunger combination energy; Fast quick-detach of large screw pitch buttress thread form and reliable locking.
Description of drawings
Fig. 1 is existing mud pump with plunger plunger means of fixation schematic representation.
Fig. 2 is the utility model plunger means of fixation schematic representation.
Figure number explanation: 1-cutting ferrule, the combination of 2-plunger, 3-cylinder sleeve, 4-frame, 5-setting sleeve, 6-fluid cylinder, 7-gland nut, 8-cylinder cap, 9-blind nut.
Embodiment
As shown in Figure 2, the mud pump with plunger that the utlity model has the quick change piston structure is directly located fluid cylinder 6 on frame 4, and whole plunger combination 2 usefulness setting sleeves 5 are located in fluid cylinder 6 and cylinder sleeve 3, lock in fluid cylinder 6 by cylinder sleeve 3 buttress threads.
Only need pull down cutting ferrule 1 during dismounting, cylinder sleeve 3 buttress threads of outwarding winding can make up plunger 2 and wholely take out from frame 4 ante-chambers, and needn't carry out any dismounting to other component of fluid end.
Structural feature of the present utility model is:
(1) passes through the improvement that fluid cylinder, cylinder sleeve and frame are located pattern, for the quick change piston structure has been stopped arrangement space;
(2) whole plunger combination is taken out from the frame ante-chamber, and needn't carry out any dismounting to fluid end;
(3) change fast, reliably lock, save the replacing time;
(4) improve drilling efficient, reduce operating cost;
(5) applied widely, can realize a tractor serves several purposes;
(6) adapt to the requirement of different drilling operating modes more.
The utility model cardinal principle: adopt the directly mode of location on frame 4 of fluid cylinder 6, for the quick change piston structure has been reserved the space.Whole plunger combination 2 usefulness setting sleeves 5 are reliably located in fluid cylinder 6 and cylinder sleeve 3, have guaranteed the installation precision that the plunger combination repeats to install.The large screw pitch buttress thread is connected to fast quick-detach and reliable locking provides guarantee.Provided direction and position that the plunger combination is taken out in the accompanying drawing 1,2, can find out clearly that the existing plungers pump plunger of the utility model takes out more convenient.
Claims (1)
1. the mud pump with plunger that has the quick change piston structure, it is characterized in that fluid cylinder (6) directly goes up the location in frame (4), whole plunger combination (2) is located in fluid cylinder (6) and cylinder sleeve (3) with setting sleeve (5) and is leaned on cylinder sleeve (3) buttress thread to lock in fluid cylinder (6).
