Description

Technical Field

[0001] This invention relates to the technical field of grease delivery, and in particular to a dual-cylinder grease filling device. Background Technology

[0002] In the telecommunications industry, the core production process for optical cables is the sheathing process. Depending on the different usage environments and laying conditions, different sheaths are added to the cable core to provide mechanical protection for the optical fiber under varying conditions. It is well known that changes in the surrounding environment in the optical cable industry can create a pressure difference between the inside and outside of the plastic sheath. If sufficient grease is not filled between the cable core and the outer sheath, moisture will typically diffuse in an unpredictable manner from the outside of the optical cable to the inside, eventually leading to undesirable high humidity inside the cable. High humidity inside the optical cable sheath can significantly damage the transmission performance of the cable; furthermore, water can enter the cable if it is damaged. Therefore, water penetration testing of optical cable products has become a mandatory inspection item for major optical cable manufacturers and operators.

[0003] Traditional grease filling methods use gear pumps to supply pressure. This method is difficult to maintain constant pressure over long periods of operation, and insufficient pressure can prevent the grease from being completely sprayed, resulting in unstable performance of the optical cable.

Oil grease is added to the oil tank 1 through the oil inlet 2. When oil grease needs to be transported, the oil pump 3 is started, drawing the oil grease from the oil tank 1 and then transporting it to the oil pipe 6. The oil pipe 6 then transports the oil grease to the pressure chamber at the bottom of the first cylinder 7. The first cylinder 7 is then started, and the piston inside the first cylinder 7 slides to increase the pressure in the pressure chamber. The oil grease is then transported through the connecting pipe 10 to the pressure chamber of the second cylinder 9. The second cylinder 9 is then started, and the piston inside the second cylinder 9 slides to increase the pressure in the pressure chamber. The oil grease is then transported through the drain pipe 11 to the drain valve 12. The drain valve 12 then transports the oil grease outwards through the oil outlet hose 13. The first cylinder 7 and the second cylinder 9 pressurize and transport the oil grease, ensuring the oil grease transport pressure and preventing pressure loss during transport from affecting the oil grease filling effect, thus improving the stability of use.

[0027] As a preferred embodiment of the above, a reinforced glass plate 14 is also included. The reinforced glass plate 14 is fixedly installed on the side of the oil tank 1 and is sealed to the main body of the oil tank 1. By setting the reinforced glass plate 14, it is convenient to observe the remaining amount of grease inside the oil tank 1 intuitively, so as to replenish the grease in real time, avoid the grease shortage affecting the grease filling, and improve the practicality of use.

[0028] As a preferred embodiment of the above, it also includes an oil inlet filter cartridge 15 and an end cap 16.

[0036] The dual-cylinder grease filling device of the present invention, during operation, adds grease to the oil tank 1 through the oil inlet 2. When grease needs to be delivered, the oil pump 3 is started, the oil pump 3 draws out the grease from the oil tank 1, and then delivers the grease to the oil delivery pipe 6. The oil delivery pipe 6 then delivers the grease to the pressure chamber at the bottom of the first cylinder 7. The first cylinder 7 is then started, and the piston inside the first cylinder 7 slides to increase the pressure in the pressure chamber. Then the grease is delivered to the pressure chamber of the second cylinder 9 through the connecting pipe 10. The second cylinder 9 is then started, and the piston inside the second cylinder 9 slides to increase the pressure in the pressure chamber. Then the grease is delivered to the oil discharge valve 12 through the oil discharge pipe 11. Then the oil discharge valve 12 delivers the grease outward through the oil outlet hose 13.

[0037] The dual-cylinder grease filling device of the present invention can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effects.
