Embodiment

[0033] The pressurization method based on the drilling pump provided with a T-shaped pump head according to the present invention comprises the following steps:

[0034] (a) First, install the suction pipe 4 on the suction liquid cylinder 3, and ensure that it communicates with the inside and the interface is sealed;

[0035] (b) Then open the suction valve 9 and the discharge valve 8, and start the piston device;

[0036] (c) Through the reciprocating movement of the piston device, the liquid is sucked from the suction flange 11 to the suction liquid cylinder 3, and enters the discharge liquid cylinder 2 after passing through the suction valve 9;

[0037] (d) Then, pressurize the liquid entering the discharge cylinder 2 through the reciprocating movement of the piston device;

[0038] (e) After the pressurized liquid passes through the discharge valve 8, it is finally discharged from the discharge pipe 12.

[0039] The suction pipe 4 is installed on the suction cylinder 3 thr...

Abstract

The invention discloses a pressurization method based on a drilling pump provided with a T-shaped pump head. The pressurization method comprises that (a) a suction tube is installed on a suction hydraulic cylinder, and the facts that the suction tube is communicated with the inside of the suction hydraulic cylinder and connecting ports of the suction tube and the suction hydraulic cylinder are sealed are guaranteed; (b) a suction valve and a discharge valve are opened, and a piston device is started; (c) liquid is sucked into the suction hydraulic cylinder from a suction flange and enters into a discharge hydraulic cylinder through the suction valve; (d) through reciprocating movement of the piston device, pressurization is carried out on liquid entering into the discharge hydraulic cylinder; and (e) the pressurized liquid is finally discharged through the discharge valve. According to the pressurization method, the structure is compact, and the size and mass are both reduced by 25%-30%; machining and manufacturing are easy, crack detection and inspection are convenient, and quality of pump head products can be guaranteed; slurry is horizontally sucked, and suction efficiency and volume efficiency of the drilling pump are improved; liquid flow is stable, fluctuation and vibration or pressure are reduced, and impact load of the drilling pump is reduced; and replacement of the suction valve is very convenient, time is saved, and workload of disassembling, installation and replacement is little.

Description

technical field [0001] The invention relates to a boosting method based on 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 fun...
