Embodiment

[0032] The pressurization method of the drilling pump applied to the petroleum industry that the present invention relates to comprises the following steps:

[0033] (a) First, open the suction valve 8 and the discharge valve 10, and start the piston device;

[0034] (b) The liquid is sucked into the suction valve box 1 by the suction flange 12, and enters the discharge valve box 2 after passing through the suction valve 8;

[0035] (c) Then, the piston 6 in the piston device moves back and forth, thereby pressurizing the liquid entering and discharging the valve box 2;

[0036] (d) After the pressurized liquid passes through the discharge valve 10, it is finally discharged.

[0037] The equipment used in the present invention such as figure 1As shown, it is mainly composed of a suction valve box 1 and a discharge valve box 2 connected internally. The discharge valve box 2 is installed on the pump casing 3 and also includes a piston device communicated with the discharge val...

Abstract

The invention discloses a pressurization method of a welling drilling pump applied to a petroleum industry. The pressurization method comprises: (a) firstly, a suction valve (8) and a discharging valve (10) are started, and a piston device is started; (b) liquid is sucked into a suction valve box (1) from a suction flange (12) and enters into a discharging valve box (2) through the suction valve (8); (c) then, a piston (6) in the piston device conducts back-and-forth motion, and therefore, the liquid entering into the discharging valve box (2) is pressurized; (d) pressurized liquid is finally discharged through the discharging valve (10). The pressurization method can enable liquid flow to be stable, reduces vibration and pressure fluctuation, and the suction valve can be independently dismantled so as to facilitate maintaining.

Description

technical field [0001] The invention relates to a pressurization method for a drilling pump used in the petroleum industry. 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 functi...
