Description

Technical Field

[0001] The utility model belongs to the technical field of oil injection pumps, and in particular relates to an automatic diesel oil injection device. Background Art

[0002] During the wireline logging operation, the diesel powered equipment that drives the cable up and down must keep running continuously to provide power to the wireline logging winch. The diesel in the diesel powered equipment tank must be kept sufficient. At present, in some operating areas, due to geographical restrictions, diesel is mostly supplied on-site by the operator or the well crew. The usual supply methods are: Figure 1 As shown, the logging team provides their own diesel barrels. They first pour diesel supplied from the well site into the barrels, let it settle, and then manually pump it into the power equipment tanks. On the one hand, manual pumps are labor-intensive, requiring team members to regularly check the tank liquid level, which takes up their attention. On the other hand, the quality of diesel that has been left to settle is difficult to guarantee. Filling with diesel containing impurities can cause the power equipment to stall during operation, resulting in a sudden loss of power to the wireline logging winch, leading to significant economic losses and endangering operational safety. Furthermore, if diesel is not added in a timely manner, a serious loss of power can also occur. Utility Model Content

[0013] Preferably, the control unit is also connected to a signal warning light.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] The utility model proposes an automatic diesel oil filling device, including a diesel barrel B2, a power equipment fuel tank B1 and a connecting pipeline, and also includes a control unit C. The connecting pipeline between the oil outlet P2 of the diesel barrel B2 and the oil inlet P1 of the power equipment fuel tank B1 is also sequentially provided with a pneumatic pump D, a filter group and a viscosity tester M3. The air inlet of the pneumatic pump D is connected to an air source pipeline. The air inlet of the pneumatic pump D is used to introduce compressed air into the interior of the pneumatic pump D for internal power transmission; an air filter F1 and a solenoid valve V1 are provided on the air source pipeline, and the solenoid valve V1 is electrically connected to the control unit C.

[0026] A first liquid level sensor M1 is installed in the power equipment oil tank B1, and a second liquid level sensor M2 is installed in the diesel barrel B2. The first liquid level sensor M1 and the second liquid level sensor M2 are electrically connected to the control unit C respectively;

[0027] The viscosity detection meter M3 is electrically connected to the control unit C. The viscosity detection meter M3 is used to detect whether the viscosity of the diesel passing through the connecting pipeline meets the standard. In one embodiment, the viscosity of the diesel that meets the standard is less than or equal to 10mm2 / s. If the viscosity of the passing liquid is detected to be greater than 10mm2 / s, it means that the diesel still cannot meet the standard after filtering.

[0028] The control unit C is a single chip microcomputer or a PLC, and the pneumatic pump D, the viscosity test meter M3, the air filter F1, the solenoid valve V1, the first liquid level sensor M1, and the second liquid level sensor M2 are all existing technologies, and their specific structures are not repeated here.

[0029] In one embodiment, the filter group includes at least a first filter F2 and a second filter F3. The at least two-stage filtration can further filter out impurities in the diesel.

[0030] In one embodiment, a pressure regulating valve V2 is further provided on the air source pipeline between the air filter F1 and the solenoid valve V1.

[0031] In specific implementation, under normal circumstances, the air pressure of the compressed air is adjusted to 50psi through a pressure reducing valve, and the pneumatic pump D uses a low-speed pump with a pumping speed of 2L / min at 50psi. The diesel can be fully filtered by the low-speed pump.

[0032] In one embodiment, when the liquid level in the power equipment tank B1 reaches a low level L, the first liquid level sensor M1 outputs a start oil filling signal S1 to the control unit C; when the liquid level in the power equipment tank B1 reaches a high level H, the first liquid level sensor M1 outputs an oil full signal S2 to the control unit C.

[0033] The low and high levels of the liquid level in the power equipment oil tank B1 are preset and can be adjusted by the staff according to actual conditions.

[0034] In one embodiment, the control unit C opens the solenoid valve V1 in response to the start-up oil filling signal S1 and maintains the opening for a period of time T before automatically closing the solenoid valve V1. The length of the time T is calculated based on the capacity of the power equipment tank B1 and the pumping speed of the pneumatic pump D and can be adjusted on-site. For example, if a power equipment tank B1 with a capacity of 120 to 150 L and a pneumatic pump D with a pumping speed of 2 L / min at 50 psi is used, the time T can be set to 1 hour. This design can avoid diesel leakage caused by continued pumping after a problem with the full oil signal occurs.

[0035] In one embodiment, when the viscosity detection meter M3 detects that the viscosity of the diesel passing through the connecting pipeline does not meet the standard, it outputs a stop signal S3 to the control unit C; after the liquid level in the diesel barrel B2 reaches a low level, the second sensor outputs a stop signal S4 to the control unit C; the control unit C controls the solenoid valve V1 to close according to any one of the stop signals S3 and S4.

[0036] The low position in the diesel barrel B2 is pre-set and can be adjusted by the staff according to actual conditions.

[0037] In one embodiment, the control unit C is further connected to a signal warning light L1. When the solenoid valve V1 is closed and the diesel pumping stops, the signal warning light comes on to alert the on-site personnel, who can then troubleshoot the problem based on the warning signal.

[0038] In one embodiment, the signal warning light L1 is provided with at least two colors, one corresponding to the stop signal S3 and the other corresponding to the stop signal S4. The different colors can indicate to on-site personnel whether the problem is that the diesel viscosity is not meeting the standard or the diesel tank B2 liquid level is low.

[0039] Reference Figure 2 As the best embodiment of the present utility model, in a diesel automatic oil filling device, a pneumatic pump D, a first filter F2, a second filter F3 and a viscosity detection meter M3 are sequentially arranged on the connecting pipeline between the oil outlet P2 of the diesel barrel B2 and the oil inlet P1 of the power equipment tank B1, the air inlet of the pneumatic pump D is connected to the air source pipeline, and the air source pipeline is sequentially provided with an air filter F1, a pressure regulating valve V2 and a solenoid valve V1, and the control unit C is electrically connected to the viscosity detection meter M3, the solenoid valve V1, the first liquid level sensor M1 in the power equipment tank B1, the second liquid level sensor M2 in the diesel barrel B2 and the signal alarm light.

[0040] Its working process is briefly described as follows: when the liquid level in the power equipment tank B1 reaches the low level L, the oil filling start signal S1 is output to the control unit C. Under the trigger of the low oil level signal S1, the control unit C outputs the solenoid valve opening signal S5, the solenoid valve V1 opens, and the compressed air passes through the air filter F1, the pressure regulating valve V2, and the solenoid valve V1 to reach the pneumatic pump D. The pneumatic pump D starts and pumps out the diesel in the diesel barrel B2, passes through the filter group composed of the first filter F2 and the second filter F3, and then passes through the viscosity test meter M3 and is injected into the power equipment tank B1.

[0041] During the diesel pumping process, if viscosity meter M3 detects a viscosity greater than 10 mm² / s, indicating that the filtered diesel still fails to meet the standard, it outputs a stop signal S3 to control unit C. When the liquid level in diesel barrel B2 reaches the low level, it outputs a stop signal S4 to control unit C. Upon receiving either signal S3 or S4, the control unit switches the voltage signal S5 of solenoid valve V1 to a low-level off signal. Solenoid valve V1 closes, halting diesel pumping. Simultaneously, signal alarm L1 illuminates, alerting on-site personnel who can then troubleshoot the problem based on the alarm signal.

[0042] When the liquid level in the power equipment oil tank B1 reaches the high level H, the oil full signal S2 is output to the control unit C, and the control unit also changes S5 to a low level to turn off the V1 signal. At this time, pumping stops, but the signal alarm light L1 does not light up to warn.

[0043] Using a power equipment tank with a capacity of 120-150L, ​​pressure reducing valve V2 adjusts the compressed air pressure to 50psi. Using a pneumatic pump with a pumping speed of 2L / min at 50psi, the pumping time is approximately one hour. After control unit C outputs the V1-enabling signal S5, S5 remains high for a specified time, T = 1 hour (T is calculated based on the capacity of power equipment tank B1 and the pumping speed of pneumatic pump D and can be adjusted on-site). After one hour, S5 also changes from high to low, thus stopping the pumping.

[0044] The control unit C is placed in an operating room where there is always someone on duty. Firstly, the pumping dynamics can be observed at any time. Secondly, the operating room environment is safe and safety hazards caused by electrical sparks can be prevented.

[0045] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model fall within the scope of protection of the technical solution of the utility model.
