Description

Technical Field

[0001] This utility model relates to the field of heavy oil pump technology, specifically to the piston structure of a heavy oil pump. Background Technology

[0002] The heavy oil pump, also known as the CYB series heavy oil gear pump, consists of main components such as the pump body, pump cover, gears, and shaft end seals.

[0003] The piston structure of existing heavy oil pumps is mostly one-piece in daily use, which cannot be separated and disassembled. As a result, if a component of the piston block or piston rod fails, the whole unit needs to be replaced, which increases costs. Secondly, the piston structure of existing heavy oil pumps also lacks the ability to heat the heavy oil in daily use, which results in the heavy oil having high viscosity and poor fluidity, making it difficult to transport. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a piston structure for a heavy oil pump, which has the advantages of easy disassembly and improved flowability of heavy oil, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a piston structure for a heavy oil pump, including a piston block, a circular groove on the top of the piston block, a retaining groove on the inner wall of the circular groove, a piston rod slidably connected to the inner wall of the circular groove, a receiving groove on the outer edge of the piston rod, limiting grooves on both sides of the inner wall of the receiving groove, a spring on the inner wall of the receiving groove, a movable plate fixedly installed on the extension end of the spring, limiting blocks fixedly installed on both sides of the movable plate, a retaining block and a connecting rod fixedly installed on the outer side of the movable plate, a heating chamber on the inner wall of the piston block, an electric heating wire on the inner wall of the heating chamber, and a temperature sensor fixedly installed at the bottom of the inner wall of the heating chamber.

[0006] As a preferred technical solution of this utility model: the shape of the card block is adapted to the shape of the card slot, and the card block is slidably connected to the inner wall of the card slot.

[0007] As a preferred technical solution of this utility model: the limiting block is slidably connected to the inner wall of the limiting groove, and the movable plate is slidably connected to the inner wall of the storage groove.

[0008] As a preferred technical solution of this utility model: an arc-shaped pressing plate is fixedly installed on the outer side of the connecting rod, and the bottom of the arc-shaped pressing plate is slidably connected to the top of the piston block.

[0009] As a preferred technical solution of this utility model: the outer edge of the electric heating wire is fixedly sleeved with an insulating layer, and the device is externally equipped with a controller, and the electric heating wire and the temperature sensor are both electrically connected to the controller.

[0010] As a preferred technical solution of this utility model: the piston block and piston rod are made of ceramic composite material, and the insulating layer is made of ceramic.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The piston structure of this heavy oil pump, through the cooperation between the locking block and the locking groove, allows for quick separation and replacement of the piston block and piston rod. Simply press the arc-shaped pressing plate inward, which drives the connecting rod and the movable plate to slide on the inner wall of the receiving groove, compressing the spring and causing it to deform and contract. At this time, the limiting block slides backward on the inner wall of the limiting groove, separating the locking block from the inner wall of the locking groove. This allows for the disassembly of the piston block and piston rod, enabling individual replacement of either the piston block or the piston rod. This detachable design of the piston block and piston rod means that when the piston assembly is damaged, it is not necessary to replace the entire assembly; only the damaged part can be replaced by disassembly, thus reducing costs.

[0013] 2. The piston structure of this heavy oil pump, through the combined use of an electric heating wire and a temperature sensor, allows the external controller to control the operation of the electric heating wire, which heats the interior of the piston block. This active heating of the piston block reduces the viscosity of the heavy oil during transport, thereby improving its fluidity and achieving stable and rapid transport. The piston block and piston rod, made of ceramic composite material, ensure stability at high temperatures. The temperature sensor allows for real-time monitoring of the temperature inside the heating chamber, enabling users to monitor the temperature and control the electric heating wire. The insulation layer prevents leakage of the electric heating wire. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The piston structure of the heavy oil pump includes a piston block 1, a circular groove 2 on the top of the piston block 1, a slot 3 on the inner wall of the circular groove 2, a piston rod 4 slidably connected to the inner wall of the circular groove 2, a receiving groove 5 on the outer edge of the piston rod 4, limit grooves 7 on both sides of the inner wall of the receiving groove 5, a spring 6 on the inner wall of the receiving groove 5, a movable plate 9 fixedly installed on the extension end of the spring 6, limit blocks 8 fixedly installed on both sides of the movable plate 9, a locking block 10 and a connecting rod 11 fixedly installed on the outer side of the movable plate 9, a heating chamber 13 on the inner wall of the piston block 1, an electric heating wire 14 on the inner wall of the heating chamber 13, and a temperature sensor 16 fixedly installed at the bottom of the inner wall of the heating chamber 13.

[0022] In the above structure, through the cooperation between the locking block 10 and the locking groove 3, when it is necessary to quickly separate and disassemble the piston block 1 and the piston rod 4 for individual replacement, simply press the arc-shaped pressing plate 12 inward. The arc-shaped pressing plate 12 drives the connecting rod 11 and the movable plate 9 to slide on the inner wall of the storage groove 5 and compress the spring 6, causing the spring 6 to deform and contract. At this time, the limiting block 8 slides backward on the inner wall of the limiting groove 7, causing the locking block 10 to separate from the inner wall of the locking groove 3, thereby disassembling the piston block 1 and the piston rod 4, thus achieving the purpose of replacing the piston block 1 or the piston rod 4 individually. Through the detachable setting between the piston block 1 and the piston rod 4, when the piston assembly is damaged, it is not necessary to replace the whole assembly. Only the damaged part can be replaced by disassembly, thereby reducing costs.

[0023] In a preferred embodiment: the shape of the card block 10 is adapted to the shape of the card slot 3, and the card block 10 is slidably connected to the inner wall of the card slot 3;

[0024] In the above structure, the sliding connection between the locking block 10 and the locking groove 3 facilitates the separation and disassembly of the piston block 1 and the piston rod 4, thereby achieving the purpose of replacing the piston block 1 or the piston rod 4 separately.

[0025] In a preferred embodiment: the limiting block 8 is slidably connected to the inner wall of the limiting groove 7, and the movable plate 9 is slidably connected to the inner wall of the storage groove 5.

[0026] In the above structure, the limiting groove 7 can limit the limiting block 8, thereby limiting the sliding of the movable plate 9.

[0027] In a preferred embodiment: an arc-shaped pressing plate 12 is fixedly installed on the outer side of the connecting rod 11, and the bottom of the arc-shaped pressing plate 12 is slidably connected to the top of the piston block 1;

[0028] In the above structure, the arc-shaped pressing plate 12 facilitates pressing the movable plate 9 inward, thereby improving the efficiency of disassembling the piston block 1 and the piston rod 4.

[0029] In a preferred embodiment: an insulating layer 15 is fixedly sleeved on the outer edge of the electric heating wire 14, and a controller is externally mounted on the device. The electric heating wire 14 and the temperature sensor 16 are both electrically connected to the controller.

[0030] In the above structure, the electric heating wire 14 and the temperature sensor 16 can be controlled by an external controller.

[0031] In a preferred embodiment: the piston block 1 and the piston rod 4 are made of ceramic composite material, and the insulating layer 15 is made of ceramic;

[0032] In the above structure, the electric heating wire 14 and the temperature sensor 16 are used in combination, and the electric heating wire 14 can be controlled by the external controller of the device to work, so that the electric heating wire 14 heats the inside of the piston block 1. By actively heating the piston block 1, the viscosity of the heavy oil is reduced during the transportation of heavy oil by the heavy oil pump, thereby improving the fluidity of the heavy oil and achieving the purpose of stable and rapid transportation of heavy oil. The piston block 1 and piston rod 4, which are made of ceramic composite material, result in the stability of the piston block 1 and piston rod 4 under high temperature conditions.

[0033] Working Principle: When this device is needed, it can first be used in conjunction with the locking block 10 and the locking slot 3. Then, when it is necessary to quickly separate and disassemble the piston block 1 and piston rod 4 for individual replacement, simply press the arc-shaped pressing plate 12 inward. The arc-shaped pressing plate 12 drives the connecting rod 11 and the movable plate 9 to slide on the inner wall of the receiving groove 5, compressing the spring 6 and causing it to deform and contract. At this time, the limiting block 8 slides backward on the inner wall of the limiting groove 7, causing the locking block 10 to separate from the inner wall of the locking slot 3. This allows the piston block 1 and piston rod 4 to be disassembled, achieving the purpose of replacing either piston block 1 or piston rod 4 individually. Because of the detachable design between piston block 1 and piston rod 4, when the piston assembly is damaged, it is not necessary to replace the entire assembly; only the damaged part can be replaced by disassembly, thus reducing costs. Secondly, it utilizes electricity... The combined use of heating wire 14 and temperature sensor 16 allows the external controller to control the operation of heating wire 14, enabling it to heat the interior of piston block 1. This active heating of piston block 1 reduces the viscosity of heavy oil during transport, improving its fluidity and achieving stable and rapid transport. The piston block 1 and piston rod 4, made of ceramic composite material, ensure stability at high temperatures. The temperature sensor 16 allows for real-time monitoring of the temperature inside heating chamber 13, enabling users to monitor the temperature and control heating wire 14. The insulation layer 15 prevents leakage of the heating wire 14.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
