digital borehole water pressure lugeon test equipment

digital hydrauli borehole water pressure lugeon test equipment. for borehole 60 - 120mm, max depth 500m, man portable, packer.

Digital Water Pressure Test Instrument is a digital instrument which does not rely on the drilling rig and can test water pressure in drilling hole section by section.

On ground surface, this instrument is controlled by the Main Machine(computer) to automatically control, supervise, measure, calculate, display the complete procedure of the water pressure test; Underground, the borehole packers seal the testing hole by two hydraulic blocks, the sealed high-pressure hose, water filling pipe are connected with Presser-flow Collecting System, Computer,and high pressure pump.

Compared with traditional water pressure test, this Digital Water Pressure Test Instrument can finish the test of one ready hole at one time.

The borehole packers are connected with the Collection Device all by soft high-pressure hoses, which can avoid leaking. And the computer can be set different test models, such as single point test and multi-point test.

The sealing length can be adjusted. For test of each sealing section, the test data can be automatically recorded, all the parameters, Lugeon value, and permeability coefficient data during test process can be recorded by the computer.
