Abstract

The invention discloses a drilling pump with a T-type pump head, and the drilling pump with the T-type pump head is substantially formed by a shell body (1), a discharge liquor cylinder (2) arranged on the shell body (1), a discharging pipe (12) connected and communicated with the discharge liquor cylinder (2), a liquid suction cylinder (3) connected and communicated with the discharge liquor cylinder (2), and a suction pipe (4) connected and communicated with the liquid suction cylinder (3). A piston device communicated with the discharge liquor cylinder (2) is arranged inside the shell body (1). The drilling pump with the T-type pump head is in a compact structure and cancels a suction chamber, the volume and the quality of the drilling pump with the T-type pump head are reduced by 25% - 30%. The drilling pump with the T-type pump head is easy to process and manufacture, convenient to flaw detect and inspect, and can ensure the quality of the pump head products. Slurry is sucked in a horizontal mode, 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, the pressure fluctuation and vibration is reduced, and the drilling pump impact load is 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. 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 characteristics and functions of the pump, it can ...
