Description

A kind of piston type well washing apparatus

Technical field

The utility model is related to a kind of well-flushing equipment, specifically a kind of piston type well washing apparatus.

Background technology

Well-flushing refers to due to requirement of engineering, during workover treatment, by well-flushing medium by pumping-in equipment through pit shaft or brill Bar injects, and the material (liquid phase, solid phase, gas phase) in pit shaft is carried to ground, so that the medium character changed in pit shaft reaches The process of job requirements.

The method of well-flushing has：1st, clear water is pumped into former drilling pump, that is, clear water is changed after starching, and is further continued for circulation well cleanup, is claimed Water flushing；2nd, stop clear water circulation, continuously carried up and down in well casing with piston, build-up of pressure is exciting, destroy borehole wall mud skin, Water-bearing layer hole is dredged simultaneously, claims piston well-flushing, piston well-flushing to need the alternate repetition to carry out；3rd, before bailing test, centrifugation is first used Pump or air compressor, groundwater abstraction reach water clearly and stabilization water outlet, then carry out bailing test, referred to as pumping well-flushing or pressure Contracting air circulation.

In piston well-flushing, rely primarily on piston deadweight and impact is produced to well casing inner aqueous layer, it is very big that this requires that piston has Weight, otherwise produce to agitate power not enough, be just difficult to wash away by borehole wall epithelial layer.In number of patent application In 201220296850.7 a kind of portable piston well-flushing equipment, piston is connected on hoist engine using steel wire rope, instead Piston is lifted again, because steel wire rope and piston space are flexible connection, it is impossible to transmit power, therefore, same can only rely on piston Produced when decline is focused on and agitated, additionally, hoist engine needs repeatedly starting and stopping to invert, not only the service life generation to motor is very big Influence, fault rate is high, and lifting speed is slow, and efficiency is low.
