I.General Description:
Seam fracturing stimulation can connect borehole with natural leader effectively, and
Distribute the pressure drop around the borehole more widely, increase deliverability
and the gas desorption rate. Therefore, Seam fracturing stimulation is generally used in the coal exploration and development as an important enhanced measure.
Seam water injection is to pour and inject the water into coal seam before mining, coal seam can discharge damp through water injection to ensure safe production, and also the coal seam can make coal wet, to avoid stirring up the dust, improve working conditions , make coal relaxation, and improve mining efficiency.
II.Applicable conditons
In view of versatile drilling conditions of different mine wells, seam fracturing water injection pump can be fit for coal seam water injection, seam penetration, Seam fracturing, seam drainaging, seam roadway cleaning and other technological process, which fullfill vary usage in one machine, improve the efficiency of coal drilling and reduce the operating costs of users.
III.Structure
This pump is mainly composed of power end, reducing gear box, fluid end, lubrication system, explosion proof motor used in mine, skid-mounted base and other components.
According to different requirement of users, some different pump unit designed as follows:
Pump ─ reducing gear box ─ direct-drive motor
Pump ─ reducing gear box ─ hydraulic gear box ─ motor combinate transmission Pump ─ standard reducing gear box ─ hydraulic gear box motor ─ combinate transmission
