Quick energy saving impactor used for well

Abstract

The invention provides a quick energy saving impactor used for a well. The quick energy saving impactor comprises a check valve, an air distributing seat, an inner cylinder and a piston, wherein the check valve comprises a long shaft part and a head part; one end, which is far away from the head part, of the long shaft part is provided with a shaft shoulder; the long shaft part is sheathed with the air distributing seat; the air distributing seat is provided with a mounting hole; the long shaft part is sheathed with a spring; one end of the spring is spaced through the shaft shoulder; the other end of the spring is in contact with the bottom of the mounting hole. The quick energy saving impactor has the advantages of reasonable structure design, small pressure loss and good energy saving effect, solves the problems that an impactor in well construction is always subjected to back-filling blockage and piston lubrication is poor and also solves the technical problems that a piston cylinder is always broken, the gas consumption of the impactor is high and working efficiency is low due to a short oriented surface.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a hammer device, in particular to a fast energy-saving hammer for water wells. Background technique [0002] At present, most of the known down-the-hole impactors for water wells have such problems: first, the spring is installed in the inner hole of the check valve, and the mating surface of the check valve and the gas distribution seat extends to the end face of the inner hole, and the check valve is When it is opened repeatedly, the end face will be swollen and deformed after colliding with the bottom of the inner hole of the valve seat, and the check valve will be stuck, which will easily cause the impactor to backfill and block; second, the guide surface of the piston is short, causing the piston to break the cylinder Third, the piston is light in weight, low in efficiency and high in energy consumption for large-diameter water well construction; fourth, the inner cylinde...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to provide a fast energy-saving impactor for water wells in view of the shortcomings of the existing technology. Compared with the 25 kg air compressor, the impactor has a reasonable design and small pressure loss. , the energy-saving effect is good, and it solves the technical problems that the impactor is prone to backfilling and clogging during water well construction, the piston is poorly lubricated, and the piston grinding cylinder is easily broken due to the short guide surface, the impactor has a large gas consumption and low work efficiency.
