Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil drilling pumps, in particular to a drilling pump suction pipe water level monitoring device. Background Art
[0002] At present, most of the drilling pumps used in oil fields are plunger pumps or piston pumps. The suction pipe of the drilling pump is connected to the water tank through a water pipeline. These two types of pumps drive the plunger or piston to reciprocate through the connecting rod at a low crankshaft speed (less than 180 rpm) to achieve suction action, and the drilling pump requires a large displacement when operating. Therefore, the drilling pump is intermittent and large-flow pumping, and the water flow in the suction pipe is always in an intermittent turbulent state, and has a strong impact. Since the water flow condition of the suction pipe changes dramatically and complexly during the operation of the drilling pump, there is currently no direct and effective technical means to monitor the water level of the suction pipe of the drilling pump. The commonly used judgment method is to identify it based on the water level of the water tank, that is, to judge whether the drilling pump is normal based on the water level of the water tank. When the water level is higher than the suction port of the water pipeline, it is considered that the drilling pump is in a normal working state, and vice versa. The above method is easy to cause misidentification if the water pipeline is blocked or the valve is misoperated, resulting in damage to the drilling pump due to empty suction, which increases the equipment cost. In addition, a special person is required to check whether the water level in the water tank is higher than the suction port of the water pipeline. Any negligence will cause damage to the drilling pump due to empty suction. This arrangement of special personnel to check not only increases the labor intensity of the staff, but also increases the operating cost.
[0003] As we all know, the diameter of the suction pipe of the drilling pump is mostly 100mm to 200mm. Due to the influence of the suction pipe diameter, it is impossible to directly arrange an ordinary liquid level sensor on the suction pipe. Therefore, there is an urgent need for a monitoring device that can accurately monitor the water level in the suction pipe to avoid empty suction of the drilling pump. Utility Model Content

By installing a water level detection part in the suction pipe, when the water level in the suction pipe reaches the height of a first water level probe and a second water level probe, the two water level probes are connected into a passage by detecting liquid, and an alarm device sends an alarm signal to avoid damage to the drilling pump due to empty suction, thereby greatly extending the service life of the drilling pump, saving operating costs, and reducing the labor intensity of staff. The structure is simple.
[0005] To achieve the above object, the utility model adopts the following technical solution: a drilling pump suction pipe water level monitoring device, comprising a suction pipe, a water level detection member is provided on the top of one end of the suction pipe, and the water level detection member comprises a probe mounting portion and a wire connecting portion;
[0006] One end of the probe mounting portion is connected to the wire connecting portion, and the other end is provided with two first water level probes and a second water level probe distributed at intervals, wherein the first water level probe and the second water level probe are on the same horizontal plane;
[0007] The drilling pump suction pipe water level monitoring device also includes an alarm device connected to the wire connection part. When the water level in the suction pipe reaches the height of the first water level probe and the second water level probe, the two water level probes are connected to form a passage by detecting liquid, and the alarm device sends an alarm signal.
[0008] As an improvement of the utility model, a blocking plate is provided at one end of the suction pipe, and a mounting hole sealed and connected to the probe mounting part is opened on the top of the blocking plate.

[0010] As an improvement of the present utility model, the water level stabilizing member is a tubular elbow-shaped structure, the shape of its water inlet is a conical trumpet-shaped structure, and the direction of the water inlet is downward.
[0011] The beneficial effects of the utility model are as follows: the utility model provides a drilling pump suction pipe water level monitoring device, by installing a water level detection part in the suction pipe, two first water level probes and second water level probes on the same horizontal plane are both installed at the top position of the suction pipe, when the water level in the suction pipe reaches the height of the first water level probe and the second water level probe, the two water level probes are connected into a passage by detecting the liquid, and the electrical signal generated by the water level detection part is transmitted to the alarm device through the connecting wire, the alarm device sends an alarm signal, and the on-site staff responds in time according to the alarm signal.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a drilling pump suction pipe water level monitoring device includes a suction pipe 1, and a water level detection member 3 is provided at the top of one end of the suction pipe 1. In this embodiment, the water level detection member 3 is arranged at the top of the right end of the suction pipe 1. The water level detection member 3 includes a probe mounting portion 33 and a wire connecting portion 32; one end of the probe mounting portion 33 is connected to the wire connecting portion 32, and the other end is provided with two first water level probes 31 and second water level probes 34 distributed at intervals, and the first water level probes 31 and the second water level probes 34 are on the same horizontal plane. The drilling pump suction pipe water level monitoring device also includes an alarm device 4 connected to the wire connecting portion 32. When the water level in the suction pipe 1 reaches the height of the first water level probe 31 and the second water level probe 34, the two water level probes are connected to form a passage by detecting liquid, and the alarm device 4 sends an alarm signal. The on-site staff immediately stops the machine to investigate the cause according to the alarm signal. It should be noted that the above-mentioned alarm device 4 and how the alarm device 4 realizes the alarm are existing mature technical means, which will not be introduced in detail here.
[0020] A baffle plate 6 is provided at one end of the suction pipe 1, and a mounting hole 61 is provided at the top of the baffle plate 6 for sealing connection with the probe mounting portion 33. Preferably, the sealing connection can be achieved by threaded connection or clearance fit followed by sealing with a sealant, etc. The present embodiment does not limit the specific sealing connection method. A water level stabilizing member 2 for stabilizing the water level around the first water level probe 31 and the second water level probe 34 is provided inside the suction pipe 1.
