AI Technical Summary
Under low temperature conditions or when using grease with higher grades, traditional pump station refueling methods can easily cause pump wicking to evaporate, resulting in grease being unable to be pumped, and the system is paralyzed, requiring manual interference to solve this problem.
A grease replenishing pipeline is designed to directly set the grease replenishing port at the pump core. By setting up grease suction lines of inclined pipes, uphill surfaces and upward channels, ensure that grease can enter the oil suction chamber smoothly and be sucked in by the pump core.
Through this design, replenishing oil directly at the oil suction port of the pump cord can effectively prevent the occurrence of empty suction problems. When empty suction occurs, directly starting the fat supplement can easily solve the empty suction problem without adding any auxiliary components.

Abstract
Description
Technical Field
[0001] The utility model relates to a grease replenishing pipeline, in particular to a grease replenishing pipeline which can prevent a pump from sucking empty. Background Art
[0002] The traditional refueling method of pumping station is Figure 1 In the method shown, the oil supply pipeline is directly connected to the grease filling port 1'. This refueling method is for greases with relatively low grades (0-1#). The grease has relatively good fluidity and can flow to the oil suction port to be sucked by the pump core and then pumped out. However, if the fluidity of the grease under low temperature conditions (below minus 10°C) or the grease with higher grades (2-3#) drops rapidly, the pump core will be sucked empty, which will directly lead to the grease being unable to be pumped and the system being paralyzed. Manual intervention is required to stir the grease and push it to the vicinity of the oil suction port, or to heat the grease to 100°C, or to pour in engine oil to reduce the viscosity of the grease. Manual intervention is time-consuming and labor-intensive, and active heating increases safety hazards. Pouring in engine oil will change the parameters of the original grease and reduce the lubrication effect. Summary of the invention

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figures 2 to 3 The utility model discloses a grease replenishing pipeline for preventing a pump from sucking empty. The grease replenishing pipeline is arranged at a pump core 1. The grease replenishing pipeline includes a grease replenishing port 2, an oil suction chamber 3 and a grease suction line. The grease replenishing port 2 is opened at the oil suction port 4 of the pump core. The oil suction port 4 is connected with the oil suction chamber 3 in the pump core 1. The oil suction chamber 3 contains an oil suction piston rod 5. A grease suction line is opened obliquely above the oil suction chamber 3. The grease suction line includes an inclined pipeline 6, an upslope surface 7 and an ascending channel 8 arranged in sequence from bottom to top. Grease enters from the grease replenishing port 2, passes through the oil suction chamber 3, and is sucked into the grease suction line by the pump core 1.
[0017] The end of the oil suction piston rod 5 is embedded in the slider 15 in the center of the pump core 1. A camshaft 13 is arranged in the center of the slider 15. A cam 9 is installed at the end of the camshaft 13. The camshaft 13 is driven to rotate by the reduction motor 11. The bottom of the slider 15 is sleeved on the slider guide rod 16. The two ends of the slider guide rod 16 are fixed on the pump core housing 10.
[0018] The shaft of the reduction motor 11 is meshed with the upper gear fixing shaft 14 for transmission. An oil pressure plate 17 is installed on the top of the gear fixing shaft 14 , and the oil pressure plate 17 is installed in the oil storage barrel 12 .
[0019] The shape of the slider 15 is U-shaped, and the cam 9 at the end of the camshaft 13 is embedded in the U-shaped groove.
[0020] As the reduction motor 11 drives the camshaft 13 to rotate, the rotation of the camshaft 13 drives the slider 15 to move left and right, and the slider 15 slides left and right on the slider guide rod 16. The slider 15 is in surface contact with the camshaft 13, and the end of the oil suction piston rod 5 is embedded in the slider 15, so that the oil suction piston rod 5 slides back and forth in the oil suction chamber 3.
[0021] The reduction motor 11 is working, and the shaft of the reduction motor 11 drives the camshaft 13 to rotate. The head of the camshaft 13 is set at the center of the slider 15. The outer side of the slider 15 is supported by the oil suction piston rod 5. The lower part of the slider 15 is sleeved on the slider guide rod 16. The two ends of the slider guide rod 16 are fixed on the pump core housing 10. The shaft of the reduction motor 11 is meshed with the gear fixing shaft 14 for transmission. The top of the gear fixing shaft 14 is installed with an oil pressure plate 17. The oil pressure plate 17 is installed in the oil storage barrel 12. The oil pressure plate 17 rotates with the rotation of the gear fixing shaft 14.

[0023] The utility model does not need to add any auxiliary components, only needs to change the layout route of the grease replenishing pipeline. The original grease replenishing port interface is moved to the plug of the pump core oil suction port, and oil can be directly replenished at the pump core oil suction port. When air suction occurs, the air suction problem can be easily solved by directly starting the grease replenishing.
