Abstract

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.

Description

technical field [0001] The invention relates to a drilling pump provided with a T-shaped pump head and a pressurization method thereof. Background technique [0002] Reciprocating pumps are widely used in the petroleum industry. Petroleum mines often need to transport liquids with high viscosity, large specific gravity and high sand content under high pressure, but the flow rate is relatively small. It is shown from the comparison of the working characteristics of various pumps , reciprocating pumps are more suitable for this situation. The reciprocating pump is used for circulating mud and injecting cement while drilling. During oil production, it is used for crude oil transportation, well washing, water injection and formation fracturing. Deep well pumps in oil pumping equipment are also reciprocating pumps with a special structure. Therefore, the reciprocating pump is one of the common and key equipment in petroleum. [0003] According to the structural characteristic...
