[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 - Figure 8 As shown, the present invention proposes an electrically driven pressure skid pump body with easy maintenance, including a sealing cover 1, a housing 2 and a locking assembly 3. The top and bottom of the housing 2 are provided with mounting plates 203 near the back. The mounting plates 203 have two fixing holes inside. The housing 2 can cooperate with the sealing cover 1 to form a pump body, so as to provide a position for the internal components. The mounting plates 203 can be used with bolts to fix the housing 2 to ensure the installation stability of the pump body.

[0029] A sealing cover 1 is installed on the front of the housing 2. A controller 101 is fixedly installed on the front of the sealing cover 1. The sealing cover 1 provides a mounting position for the controller 101 and cooperates with the locking component 3 to connect and secure the sealing cover 1 to the housing 2, forming a closed space to provide a stable and safe working environment for the internal components, so as to facilitate the transmission of fluids such as crude oil. The controller 101 can be connected to other electronic components through wires to control multiple electronic components to work together.

[0030] A locking component 3 is installed through the housing 2 and the sealing cover 1. The locking component 3 can connect the housing 2 and the sealing cover 1 and automatically tighten the housing 2 and the sealing cover 1 to prevent leakage at the joint of the pump body and ensure the safety and stability of the pump body.

[0031] Furthermore, the locking assembly 3 includes a threaded rod 302 that penetrates both the housing 2 and the sealing cover 1. A limit bolt 301 is installed at the end of the threaded rod 302 facing the housing 2 via a threaded structure. A motor 304 is installed at the end of the threaded rod 302 away from the limit bolt 301, and the housing of the motor 304 is fixedly connected to the sealing cover 1. An adjusting bolt 305 is installed on the outer side of the threaded rod 302 via a threaded structure and is fixedly connected to the housing 2. A mounting plate 303 is fixedly installed on the outer side of the motor 304. A pressure sensor 306 is fixedly installed on the side of the mounting plate 303 closest to the motor 304, and a contact head 307 is mounted against the side of the pressure sensor 306 facing the housing 2. The contact head 307 penetrates the sealing cover 1 and is fixedly connected to the housing 2. The threaded rod 302 provides mounting positions for surrounding components, and the rotation of the threaded rod 302 pushes the housing 2 and the sealing cover 1 to move relative to each other. The limit bolt 301 can limit one end of the threaded rod 302. To prevent the adjusting bolt 305 from slipping off the outside of the threaded rod 302 after excessive rotation, the motor 304 is a YE3-10KW type. When energized, the motor 304 rotates, thereby driving the threaded rod 302 to rotate. One side of the adjusting bolt 305 is fixedly connected to the housing 2, allowing the threaded rod 302 to push or pull the housing 2 to move when rotating. The mounting plate 303 provides a mounting position for the pressure sensor 306 and limits the contact head 307 to prevent it from shifting during movement. The pressure sensor 306 is an NTJH-14 type. It detects the pressure applied by the contact head 307 to determine the degree of contact between the housing 2 and the sealing cover 1. When the sealing cover 1 and housing 2 are significantly separated, the motor 304 is controlled to rotate, actively tightening any gaps between the sealing cover 1 and housing 2, ensuring good sealing throughout the pump's operation.

[0032] Furthermore, the sealing cover 1 has eight through holes inside, and each through hole matches the contact head 307. The through holes can limit the contact head 307 to prevent the contact head 307 from shifting during the movement of the housing 2, thereby enabling the contact head 307 to stably and accurately transmit pressure to the pressure sensor 306.

[0033] Furthermore, an outlet pipe 202 is fixedly installed on one side of the housing 2, and an inlet pipe 201 is fixedly installed on one side of the housing 2 below the outlet pipe 202. The outlet pipe 202 and the inlet pipe 201 can be connected to external pipes respectively, so that crude oil and other fluids can enter and exit the pump body respectively, thereby realizing the transmission of crude oil and other fluids.

[0034] Furthermore, a flange is provided at one end of both the inlet pipe 201 and the outlet pipe 202, and a locking bolt is installed inside the flange through a threaded structure. The flange and the locking bolt facilitate the connection of the inlet pipe 201 and the outlet pipe 202 to external pipelines, so that the device can be connected to the pipeline for operation.

[0035] Working principle: After installing the internal components of the pump body into the housing 2, the locking component 3 is assembled on the outside of the housing 2 and the sealing cover 1. After aligning the holes of the sealing cover 1 with those of the housing 2, the locking component 3 is assembled. The motor 304 is energized and rotates, driving the threaded rod 302 to rotate. This causes the adjusting bolt 305 to move the housing 2 along the threaded rod 302, thereby assembling and sealing the housing 2 and the sealing cover 1. The housing 2 then drives the contact head 307 to move towards the sealing cover 1, so that the contact head 307 contacts the pressure sensor 306 and applies pressure to the pressure sensor 306. The pressure sensor 306 uses the monitoring data to control the rotation of the motor 304, which in turn drives the threaded rod 302 at the corresponding position to rotate. This allows for fine-tuning at the location where there is a large gap between the sealing cover 1 and the housing 2. When internal maintenance of the pump body is required, the motor 304 drives the threaded rod 302 to rotate in the opposite direction, causing the adjusting bolt 305 to move the housing 2 away from the sealing cover 1. This accurately separates the housing 2 from the sealing cover 1 and prevents the sealing cover 1 from falling off the outside of the housing 2, which could damage internal components. This facilitates the inspection and maintenance of the components installed inside the housing 2 and the sealing cover 1.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
