Abstract
The utility model discloses a mud pump piston extractor for the oil industry, which can be used when mud pump is checked and can conveniently and rapidly extract a piston of a mud pump. The mud pump piston extractor comprises a piston extracting mechanism and a limit stress application mechanism, wherein the limit stress application mechanism is installed on the extracting mechanism, the limit stress application mechanism is matched with the piston extracting mechanism, and the piton can be extracted out. The mud pump piston extractor has simple structure and low cost, the operation is safe and convenient, the mud pump piston extractor saves time and labor, damages of piston accessories can be avoided, and the cost is saved. A traditional operation mode can be changed, the labor time is saved, the working efficiency is improved, and the unsafe factors can be reduced, which is beneficial for safe production.
Description
Technical field
The utility model relates to a kind of corollary equipment of device maintenance of petroleum industry, and particularly the mud piston extractor uses when the maintenance slurry pump, can take out the piston of slurry pump quickly and easily.
Background technique
In petroleum industry, slurry pump is the manufacturing mechanism of drilling crew, operation team indispensability, because work under bad environment running continuously in addition very easily causes mud piston to damage, changing piston for slurry pump is regular routine work.At present, change piston at the maintenance slurry pump, when taking out old piston, owing to do not have special tool, and piston cooperates with piston-cylinder closely, often uses the mode that hammer is pounded piston pulling rod that it is pounded out.Sometimes even abuse, use the gas circuit of slurry pump or crank running that circuit makes slurry pump, piston is ejected from cylinder sleeve.Not only damage equipment, also implicit unsafe factor.Effort, time-consuming is often pounded the hand accident.
Summary of the invention
The purpose of this utility model provides a kind of safe, mud piston extractor easily, increases work efficiency, and guarantees personal safety.
The present technique solution can reach above-mentioned purpose: the mud piston extractor comprises piston unloading device and spacing boosting mechanism, and spacing boosting mechanism is installed on the unloading device, and spacing boosting mechanism cooperates with the piston unloading device, and piston is taken out.
Compared with prior art, the utlity model has following useful effect: changed traditional mode of operation, saved working time, improved working efficiency.This apparatus structure is simple, and cost is low.Handling safety, convenience save time, laborsaving, have avoided the damage of piston annex, have saved cost.Avoid operating against regulations the generation of phenomenon.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, the mud piston extractor comprises piston unloading device and spacing boosting mechanism, and spacing boosting mechanism is installed on the unloading device.Spacing boosting mechanism cooperates with the piston unloading device, and piston is taken out.The piston unloading device comprises leading screw 1 and silk braid 3, and silk braid 3 is fixed on an end of leading screw 1, and silk braid 3 interior circles are provided with screw thread and cooperate with the screw thread of piston pulling rod.Spacing boosting mechanism comprises limiting stopper 2 and sleeve 5, also is provided with rotatable handle 4 on the sleeve 5, and limiting stopper 2 and sleeve 5 are installed on the leading screw 1, and limiting stopper 2 is loaded between silk braid 3 and the sleeve 5.
Operating method
1, opens the last water end (W.E.) gland of slurry pump, take out valve body assembly;
2, with the piston pulling rod screwed connection of the silk braid on the leading screw 1 of this device 3 with slurry pump.
3, overlap upper limit position block 2, the elbow of limiting stopper 2 is clamped on the through hole of water end (W.E.) gland; Again sleeve 5 is installed on the leading screw 1, holds out against jointly on slurry pump housing end face with limiting stopper 2.
4, turnbarrel 5, and leading screw 1 is outwards moved, thereby the silk braid by leading screw 1 end 3 is taken piston out of.
