Description

Technical Field

[0001] This utility model relates to the technical field of sealing grease performance testing equipment, and in particular to a pumping performance testing device for shield tail sealing grease. Background Technology

[0002] Tail shield grease is a homogeneous paste made primarily of grease, with added fibers, thickeners, fillers, and other additives. Its main functions are sealing, waterproofing, lubrication, and corrosion protection. Tail shield grease is further divided into two types: hand-applied grease and pump-propelled grease. Hand-applied grease is used at the start of propulsion, while pump-propelled grease is used during the propulsion process. Existing tail shield grease testing devices typically test only one aspect, but the pumpability performance of tail shield grease involves more than one aspect. Multiple tests are time-consuming and deplete the tail shield sealing grease. Furthermore, the high viscosity of the tail shield sealing grease makes the final testing device very difficult to clean. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies, such as time-consuming and wasteful testing of shield tail sealing grease, and the difficulty in cleaning the testing device. It provides a shield tail sealing grease pumping performance testing device that can directly test multiple properties, saves shield tail sealing grease, and is easy to clean.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pumping performance testing device for a shield tail sealing grease includes a sealing grease tank, a grease pump, a corrosion-resistant test tube, a viscosity test tube, a sealing test tube, and supports. The grease pump passes through the outer side of the sealing grease tank and is placed inside and connected to the sealing grease tank. One end of the grease pump is connected to one end of the corrosion-resistant test tube and is internally connected. The corrosion-resistant test tube, viscosity test tube, and sealing test tube are connected end to end and are internally interconnected. Several supports are evenly distributed on the lower end faces of the corrosion-resistant test tube, viscosity test tube, and sealing test tube. The lower end faces of the sealing test tubes of the corrosion-resistant test tube and viscosity test tube are respectively engaged with the upper end faces of the supports.

[0006] In use, first install the grease pump onto the sealing grease container containing the grease to be tested. Then, connect the corrosion-resistant test tube, viscosity test tube, and sealing test tube end to end as needed, ensuring the corrosion-resistant test tube is connected to the grease pump. Use a bracket to support the corrosion-resistant test tube, viscosity test tube, and sealing test tube to increase stability. Then, turn on the grease pump to transfer the sealing grease to the corrosion-resistant test tube, viscosity test tube, and sealing test tube to complete the sealing, waterproofing, lubrication, and corrosion resistance tests. After testing, simply disassemble the corrosion-resistant test tube, viscosity test tube, and sealing test tube, as the internal structure is open, facilitating cleaning. This achieves the goal of directly testing multiple properties while saving on sealing grease and making the testing device easy to clean.

[0007] Preferably, the grease pump is equipped with a grease extraction tube, one end of which is fixedly connected to the pump, and the other end of which passes through the outer side of the sealed grease container and is placed inside the container. An outlet pipe is located on the side of the grease extraction tube, one end of which is fixedly connected to and communicates with the interior of the tube.

Valves are provided on each of the corrosion resistance test tube, viscosity test tube, and sealing test tube, and are connected to them. The mounting nuts facilitate connection and disassembly, and the valves allow for the use of different test tubes as needed.

[0008] Preferably, the corrosion resistance test tube is equipped with a corrosion resistance tester, which is fixedly connected to the outer surface of the corrosion resistance test tube. The test point of the corrosion resistance tester passes through the outer surface of the corrosion resistance test tube and is placed inside the corrosion resistance test tube. The corrosion resistance tester facilitates the testing of the corrosion resistance of sealing greases.

[0009] Preferably, the viscosity test tube is equipped with a viscosity meter, which is fixedly connected to the outer side of the viscosity test tube. The test point of the viscosity meter passes through the outer side of the viscosity test tube and is placed inside the viscosity test tube. The viscosity meter facilitates the testing of the viscosity of sealing greases.

[0010] Preferably, the right end face of the sealing test tube is provided with a sealing cap and a sealing sensing baffle. The sealing sensing baffle is placed between the sealing cap and the sealing test tube, and both sides of the sealing sensing baffle are in contact with the sealing cap and the sealing test tube, respectively. The sealing cap is threadedly connected to the sealing test tube. The sealing cap facilitates sealing and waterproofing testing by pressing against the sealing sensing baffle.

[0011] Preferably, the sealing cover is equipped with a sealing tester, which is fixedly connected to the outer side of the sealing cover. The test point of the sealing tester passes through the outer side of the sealing cover and connects to the sealing sensing baffle. The sealing tester directly uses the sealing sensing baffle to test the sealing and waterproof performance.

[0012] The beneficial effects of this utility model are: it can directly test multiple properties while saving shield tail sealing grease, and the testing device is easy to clean; the mounting nut facilitates connection and disassembly, and the valve can use different test tubes as needed; the corrosion resistance tester facilitates corrosion resistance testing of sealing grease; the viscosity tester facilitates viscosity testing of sealing grease; the sealing cap facilitates sealing and waterproof testing by pressing against the sealing induction baffle; and the sealing tester directly uses the sealing induction baffle to test sealing and waterproof performance.
