Problems solved by technology

[0002] High-pressure water supply is an indispensable part of oil field water injection, boiler feed water, power source of hydraulic machinery, and food, pharmaceutical and other departments that need to generate high-pressure fluid. The existing high-pressure water supply device is often placed in a fixed position to perform high-pressure Water supply, the water supply system occupies a large area. When the field operation stops, the high-pressure water supply system will be discarded or dismantled, which cannot be recycled and increases production costs.

Embodiment 1

[0040] Embodiment one: see figure 1 , a water injection integrated integrated device, including a skid and a water injection system installed on the skid, the water injection system includes a water tank 3, a water feeding pump 9, a water treatment device 10 and a water injection pump 23, and the water inlet of the water tank 3 passes through the pipeline and The water source inlet 1 is connected, the water outlet of the water tank 3 is connected with the water inlet of the water feeding pump 9 through the pipeline, the water outlet of the water feeding pump 9 is connected with the water inlet of the water treatment device 10, and the water outlet of the water treatment device 10 is connected with the water injection through the pipeline. The water inlet of the water pump 23 is connected, and the water outlet of the water injection pump 23 is connected with the water injection outlet 32 ​​through a pipeline.

[0041] A first valve 2 is installed on the pipeline between the wat...

Embodiment 2

[0047] Embodiment two: see figure 2 , a control method based on the integrated water injection device. The parameters of the water injection pump 23 and the water injection instrument 29 are collected through the RS485Modbus protocol. Process and parameter display, through Ethernet (RJ45), TCP / IP protocol, realize data upload to industrial computer; the data to be collected includes:

[0048] Monitor the liquid level LI101 of the water tank 3, alarm when it reaches the upper limit liquid level 2.0m (can be set), and alarm when it reaches the lower limit liquid level 0.5m (can be set);

[0049] Monitor the water pressure PI101 at the water source inlet 1, and alarm when the pressure is less than 0.05MPa (can be set) or greater than 0.5Mpa (can be set);

[0050] Monitor the status of feeding pump 9 XY101;

[0051] Monitor the pressure PI202 of the water treatment device 10, alarm when the pressure exceeds 0.5MPa (can be set), and stop the feeding pump 9 and the dosing pump 12...

Abstract

The invention discloses a water injection integration apparatus and a controlling method thereof. The apparatus comprises a prying base and a water injection system installed at the prying base. The water injection system consists of a water tank, a water feeding pump, a water treatment device and a water injection pump. A water inlet of the water tank is connected with a water source inlet through a pipeline and a water outlet of the water tank is connected with a water inlet of the water feeding pump through a pipeline; a water outlet of the water feeding pump is connected with a water inlet of the water treatment device; a water outlet of the water treatment device is connected with a water inlet of the water injection pump by a pipeline; a water outlet of the water injection pump is connected with a water injection outlet by a pipeline. On the basis of the prying structure, the area occupied by the apparatus is small; assembling becomes convenient; and the apparatus can be allocated and transported repeatedly. With the pressure of the pipe network, water injection is carried out directly or indirectly after boosting, so that secondary energy wasting is avoided and the system efficiency is high; the automation degree is high and the protection functions are completed; and the unattended operation can be realized.

Description

technical field [0001] The invention belongs to the technical field of water injection devices, and mainly relates to an integrated water injection device and a control method. Background technique [0002] High-pressure water supply is an indispensable part of oil field water injection, boiler feed water, power source of hydraulic machinery, and food, pharmaceutical and other departments that need to generate high-pressure fluid. The existing high-pressure water supply device is often placed in a fixed position to perform high-pressure Water supply, the water supply system occupies a large area. When the field operation stops, the high-pressure water supply system will be discarded and dismantled, which cannot be recycled and increases production costs. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a movable and recyclable integrated water injection device and a control method thereof. [0004] Technical...
