Description
Technical field
The utility model relates to drilling mud pump technical field, specifically a kind of quick-release arrangement of mud piston.
Background technique
Slurry pump is when drilling well for circulating mud and injection cementing concrete, and a main dispatch flushing fluid, with cooling drill bit at the bottom of flushing manhole, prevents cave-in, and landwaste is carried to the effect on ground.Slurry pump connects Jie's bar by one end of piston rod usually, and the other end connects piston, for power is passed to piston through Jie's bar, piston rod, makes piston produce to-and-fro motion, realizes slurry pump and suck drilling mud, discharge the circulating mud of high pressure and inject well head.Drilling mud due to mud piston dispatch is containing being corrosive and the liquid of tempering property, so in the normal operation of drilling mud pump, many easily damaged partss need often to change, and piston just belongs to one of easily damaged parts that this kind of needs often change.
In the reciprocating pump that present situ of drilling well uses, usual Jie's bar is directly connected with clip with piston rod, when piston needs to change, does not have the withdrawal space, even if piston falls back on rear dead point, also cannot directly piston rod and piston be taken out from cylinder sleeve.So it is more loaded down with trivial details to change piston, first to pulls down clip and cylinder sleeve clip, then cylinder sleeve, piston rod be disassembled together with piston, then change the piston of damage, install by the order contrary with dismounting more afterwards, just can complete the replacing of piston.Cylinder sleeve clip and cylinder sleeve, the weight sum of these two parts is general all more than 100 kilograms, after having changed piston, also they will be installed again., there is operating personnel's labor intensity large, waste time and energy, ineffective problem in such substitute mode.How to improve piston substitute mode, reduce labor intensity, raise the efficiency, in the actual use of oil drilling and slurry pump, there is very important realistic meaning.
Model utility content
The purpose of this utility model is to provide a kind of quick replacement device of mud piston, removes with the fast dismantling realizing the piston after wearing and tearing, and improves the speed and efficiency of changing piston, reduces the labor intensity changing piston.
For achieving the above object, technical solution adopted in the utility model is:
A kind of mud piston quick replacement device, this device is installed between piston rod and Jie's bar, it comprises connecting rod, the shape of described connecting rod is dumbbell-like shape, one end of described connecting rod is connected with Jie's bar by the first clip, the other end of described connecting rod is connected with the top of piston rod by the second clip, described connecting rod two ends central axis is provided with positioning cylinder, give an account of bar, described piston rod and described connecting rod connecting end and be respectively equipped with the positioning hole suitable with described positioning cylinder, described positioning cylinder is plugged in described positioning hole.
As further improvement of the utility model, the first clamping face that described connecting rod is connected with described first clip is plane of inclination.
Further improve as of the present utility model, the first clamping face that described connecting rod is connected with described first clip is vertical surface.
Further improve as of the present utility model, the second clamping face that described connecting rod is connected with described second clip is plane of inclination.
Further improve as of the present utility model, the intermediate portion of described connecting rod is the unconverted cylindrical body of diameter.
Further improve as of the present utility model, the intermediate portion of described connecting rod is by the different stepped cylindrical body of diameter.
The utility model is arranged between Jie's bar and piston rod, and power is passed toward piston through Jie's bar, piston rod, is that piston produces to-and-fro motion.When piston needs to change, first first clip at connecting rod two ends, the second clip are disassembled, by jiggering, connecting rod and Jie's bar, piston rod are thrown off, unloads lower connecting rod; By jiggering, make Jie's bar away from piston rod, to the rear dead point of slurry pump, now occur a space between Jie's bar and piston rod, lower piston rod and piston are enough unloaded in space, realize quick-replaceable piston.In order to change piston effortlessly, after unloading lower connecting rod, Jie's bar and piston rod clip connected can also be got up, by jiggering, pull-out piston rod and piston, then unload lower catch hoop and take off piston, realize quick-replaceable piston.
The length of described connecting rod should be not less than it and lay down the distance that lower piston rod and piston are enough unloaded in rear reserved space.
In the utility model, the clamping face between connecting rod from described first clip is different and change according to the shape of connecting rod, and clamping face is plane of inclination or vertical surface.
By use of the present utility model, without the need to pulling down cylinder sleeve clip and cylinder sleeve, just can realize the quick-replaceable of piston, effectively reducing labor intensity, improve working efficiency, reach time saving and energy saving object.
