Description

Technical Field

[0001] This utility model belongs to the field of oilfield production tools technology, specifically relating to an irrigation pump device. Background Technology

[0002] In oilfield production, pumps are often primed before startup. Priming during priming involves open discharge, which can easily cause serious damage, such as from high-temperature media, flammable volatile gases, or toxic and harmful substances, affecting the efficiency and safety of oilfield production. Priming before startup effectively removes gases from the pumps, protects the equipment, extends its service life, and improves the efficiency and safety of oilfield production.

[0003] Currently, air venting is required at all work sites, which is unsafe, time-consuming, and labor-intensive. Furthermore, ensuring safety necessitates additional support personnel and tools, wasting significant manpower and causing considerable inconvenience, especially for individuals. Utility Model Content

[0004] The purpose of this utility model is to provide an irrigating pump device to solve the technical problems of unsafe, time-consuming and labor-intensive irrigating pump operation before starting the pump in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A priming pump device includes a housing with an inlet on one side and an outlet on the other side. An inlet valve is provided at the inlet and an outlet valve is provided at the outlet. An observation window is provided on the side wall of the housing, with a pressure gauge above the observation window and a temperature measuring port below it. A handle is provided on the top of the housing, with a gas detection port on the housing below the handle. A nitrogen inlet is provided on one side of the handle, and a safety valve is provided on the other side of the handle.

[0007] Preferably, the inlet connection end is provided with a pump inlet sealed connection part, and the outlet connection end is provided with a recycling equipment inlet sealed connection part.

[0008] Preferably, the sealed connection part of the inlet of the recycling equipment is connected to the recycling equipment by a threaded connection or a snap-fit ​​connection.

[0009] Preferably, the sealed connection part of the irrigation pump port is connected to the irrigation pump port by a threaded connection or a snap-fit ​​connection.

[0010] Preferably, a condensate trap is provided between the outlet valve and the housing at the outlet.

[0011] Preferably, an electrostatic discharge clip is also provided on the outer wall of the housing.

[0012] Preferably, the safety valve is equipped with a flame arrester.

[0013] Preferably, the viewing window is made of a transparent material.

[0014] Preferably, the shell is a columnar hollow structure.

[0015] Preferably, a nitrogen storage tank connected to the nitrogen inlet is provided on one side of the nitrogen inlet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This application discloses a priming pump device with an inlet on one side of the casing and an outlet on the other side. An observation window is located on the exterior of the casing, and a gas detection port, a nitrogen inlet and a nitrogen storage tank are also located on the top of the casing. A safety valve with a flame arrester is also located on the top of the casing, along with a handle and a pressure gauge. A temperature measuring port is located at the bottom. The device connects to the priming pump port via the inlet on one side of the casing, and then opens the priming pump and inlet valve, allowing the medium to flow into the casing. The gas-liquid state is determined through the observation window; when the pump is entirely liquid, the priming pump and inlet valve are closed. A temperature measuring port at the bottom allows for temperature monitoring when the pump needs warming up. The priming pump port is disconnected, and the outlet is connected to the inlet of a recovery device via a sealed connection. Nitrogen is first introduced for safety and displacement, and then the outlet valve is opened. A liquid-retaining valve is located at the front of the outlet to prevent liquid from passing through but not gas. A gas detection port allows for observation of the gas composition to determine toxicity or harmfulness. A pressure gauge is located on the top of the casing to monitor the pressure; if overpressure occurs, a safety valve releases the pressure. This device achieves a closed-loop priming pump, ensuring safety and effectiveness.

[0018] Furthermore, an electrostatic discharge clamp is connected to the outside of the housing of the priming pump equipment throughout the entire process to effectively release static electricity.

[0019] Furthermore, a flame arrester is installed on the safety valve. When the housing is overpressurized, the pressure is released through the safety valve equipped with the flame arrester. The flame arrester can ensure explosion-proof safety, and the safety valve can ensure safe pressure relief of the housing. Attached Figure Description
