Embodiment Construction

[0035] A reciprocating pump that is easily leak tested, see figure 1 and figure 2 , including a base 1, a pump body 11 is fixed on the top of the base 1, and the base 1 is located outside the pump body 11 and is detachably connected with a sealing cover 2 covering the pump body 11, and the sealing cover 2 keeps the pump body 11 in an airtight condition Next, the pump body 11 is connected with a detection device 3 for detecting whether the pump body 11 leaks. The base 1 is located outside the sealing cover 2 and is fixed with a motor 16 whose output shaft extends into the sealing cover 2. The motor 16 is used to drive the pump body The valve rod of 11 reciprocates.

[0036] see figure 2 and image 3The sealing cover 2 includes a cover body 21, the four corners of the base 1 corresponding to the cover body 21 are fixed on the vertically arranged screw rod 12, the four corners of the cover body 21 are provided with through holes 22, and the through holes 22 are used for supp...

Abstract

The invention discloses a reciprocating pump capable of easily detecting leakage, which belongs to the field of reciprocating pumps and comprises a base, a pump body is fixedly arranged at the top ofthe base, a detection device for detecting whether the pump body leaks or not is arranged at the top of the base, and the pump body in a sealing cover is connected with the detection device for detecting whether the pump body leaks or not. The detection device comprises: a detection circuit, which is used for detecting whether a pump body in a cover body leaks or not, and outputting a high-level signal when detecting that the pump body in the cover body leaks; a control circuit which is coupled with the detection circuit and receives the high-level signal output by the detection circuit, wherein when the control circuit receives the high-level signal output by the detection circuit, a control signal is output; and a prompt circuit which is coupled with the control circuit and receives thecontrol signal output by the control circuit, wherein when the prompt circuit receives the control signal output by the control circuit, prompt information is sent out to remind a worker of leakage ofthe pump body. The reciprocating pump has the effect of automatically detecting whether the reciprocating pump leaks or not.

Description

technical field [0001] The invention relates to the technical field of reciprocating pumps, in particular to a reciprocating pump which is easy to detect leaks. Background technique [0002] As the development of oil and gas fields, especially unconventional oil and gas resources, is becoming more and more difficult, the scale of drilling, well completion, fracturing and other construction operations is also increasing. High-power, high-pressure, high-displacement well washing, cementing, fracturing and other construction operations are more frequent, and the single well operation time is longer. The core equipment in the above operation process is the reciprocating pump that realizes the pumping circulation of mud, fracturing fluid, cement and other liquids or liquid-solid mixtures. Therefore, with the increase in scale, frequency and duration of the above-mentioned construction operations, the requirements for reciprocating pumping equipment are also getting higher and hi...
