Embodiment 1

[0012] Example 1 The manifold pressure and water release device and working process of the diesel water pump unit using electric valves are as follows:

[0013] Such as figure 1 As shown, the entire diesel water pump unit is composed of two water pumps 2 with one standby and one active structure. The two water pumps 2 suck the water in the primary storage tank from the water inlet pipe 1, and the two water pumps are the outlet pipes of one standby and one active. Connected to one piece together with the inlet and outlet pipes 4 to form a manifold structure. The inlet and outlet pipes 4 are connected to the primary reservoir 9 through the discharge pipe 3; the valve 6 is connected to the discharge pipe 3, and the valve 6 is an electric valve; In the middle of the unit; the outlet pipes of the two diesel water pumps 2 are equipped with pressure sensors 12 .

[0014] When the diesel water pump unit manifold pressure relief device works, the control system sets the normal value ...

example 2

[0016] Example 2: The manifold pressure and water release device and working process of the diesel water pump unit using manual valves, branch pipes, and safety valves are as follows:

[0017] Such as figure 2 As shown, the entire diesel water pump unit is composed of two water pumps 2 with one standby and one active structure. The water in the primary reservoir is sucked into the water pump 2 from the water inlet pipe 1, and the outlet pipes of the two water pumps are connected to one Together with the inlet and outlet pipelines 4, a manifold structure is formed. The manifold pressure and water relief device of the diesel water pump unit is in the middle of the whole unit and consists of a manual valve, discharge pipe 3, branch pipe 8, and safety valve 7.

[0018] When the diesel water pump unit manifold pressure relief device is working, the manual valve of the diesel water pump unit manifold pressure relief device is closed. When the pressure in the pipeline is too high, ...

Abstract

The invention relates to a pressure relief and water drainage device of a manifold of a diesel oil water pump unit. The problems that in an existing diesel oil water pump unit, after well site work iscompleted, too much water is left in an environment-friendly impounding reservoir and a water conveying pipeline, and the water cannot be drained are mainly solved. The pressure relief and water drainage device is characterized in that two water pumps (2) are connected with a first-stage impounding reservoir (9) through water inlet pipelines (1); water outlet pipelines of the two water pumps (2)are connected together through an inlet and outlet pipeline (4); the inlet and outlet pipeline (4) is connected with an environment-friendly impounding reservoir (10) through two water outlet pipes (11); valves are connected to the water outlet pipes (11); check valves (5) are connected to the water outlet pipelines of the two diesel oil water pumps (2) correspondingly; the inlet and outlet pipeline (4) is connected with the first-stage impounding reservoir (9) through a discharging pipe (3); and a valve (6) is connected to the discharging pipe. According to the pressure relief and water drainage device of the manifold of the diesel oil water pump unit, a great amount of water stored in the water outlet pipelines and the environment-friendly impounding reservoir can be smoothly drained out, environment pollution can be reduced, and safe production can be guaranteed.

Description

technical field [0001] The invention relates to the field of oil exploitation fracturing equipment, in particular to a novel pressure and water release device for a manifold of a diesel water pump unit. Background technique [0002] In the process of oil and gas field exploitation, the use of fracturing technology is one of the important technical means to increase reserves and production in oil and gas fields. Through fracturing operations on oil and gas wells, it can enhance the permeability of oil and gas layers, improve the flow environment of oil and gas at the bottom of the well, and achieve the goal of increasing oil and gas production. production purpose. During fracturing operations, the performance of fracturing equipment directly determines the effect of fracturing oil and gas wells and the increase in oil and gas production. At present, fracturing equipment is mainly composed of fracturing pump trucks, sand mixing trucks, instrument trucks, high-pressure manifol...
