The invention discloses a drilling pump with a T-type
pump head. The drilling pump with the T-type
pump head is mainly formed by a shell body, a
discharge liquor cylinder arranged on the shell body, a discharging
pipe connected and communicated with the
discharge liquor cylinder, a suction liquor cylinder connected and communicated with the
discharge liquor cylinder, and a suction
pipe connected and communicated with the liquid suction cylinder. A
piston device communicated with the discharge liquor cylinder is arranged inside the shell body. The invention further discloses a supercharging method based on the drilling pump. The drilling pump with the T-type
pump head is in a compact structure and a suction chamber is canceled, the volume and the quality of the drilling pump with the T-type pump head are both reduced by 25% - 30%. The drilling pump with the T-type pump head is easy to process and manufacture, convenience is brought to flaw detect and inspection, and can ensure the quality of pump head products.
Slurry is sucked horizontally, the clearance volume in the pump head cylinder is small, the suction efficiency and the
volumetric efficiency of the drilling pump are improved; liquid flow is smooth, pressure fluctuation and pressure vibration are reduced, and drilling pump
impact loads are also reduced. The change of a suction valve is very convenient and time-saving, and the
workload of dismounting and changing is little.
