Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a fat supply system. Background Art

[0002] In many industrial equipment, especially in mechanical equipment with strict lubrication requirements, viscous grease is often required to ensure good lubrication and operation of components. However, compared with liquid oil, viscous grease faces some challenges in the oil supply process due to its high viscosity and poor fluidity.

[0003] First of all, the traditional pressure tank oil supply system performs poorly when dealing with viscous grease. This is because grease is relatively viscous and has poor fluidity, so it is impossible to use a pressure tank to directly supply oil. The pressure tank mainly relies on gas pressure to push the liquid, and the flow resistance of viscous grease is large, making it difficult for gas pressure to effectively push the grease to the position where the equipment needs to go. When using gas to push the grease, the gas can easily enter the grease, causing bubbles in the grease. Utility Model Content

[0004] The purpose of the utility model is to provide a fat supply system to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fat supply system, comprising

[0007] Tank;

[0008] The top of the tank body is provided with an upper cover plate, the bottom of the tank body is provided with a lower cover plate, and a piston is movably installed inside the tank body;

[0009] Both ends of the upper cover plate are provided with compressed air inlets, and both ends of the lower cover plate are provided with grease outlets.

[0010] Preferably, the two compressed air inlets are connected to the interior of the tank body, and the two grease outlets are connected to the interior of the tank body;

[0011] Preferably, a liquid level sensor is provided on the outside of the tank;

[0012] Preferably, a lifting ring is movably installed at the top of the upper cover plate;

[0013] Preferably, sealing rings are sleeved on both upper and lower sides of the outer wall of the piston;

[0014] Preferably, the lower interior of the tank body is funnel-shaped.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] When the grease supply system is in use, the valves on the pneumatic grease pump and the grease outlet pipeline are opened. As the grease enters, the piston moves upward. After the liquid level sensor detects the piston, the grease is stopped from being pumped in. Then the compressed air inlet is connected to the compressed gas. The grease pressure can be adjusted by adjusting the pressure of the compressed air. At this time, by adjusting the pressure at the compressed air inlet, the compressed gas enters the tank body and applies pressure to the grease. The pressure of the compressed gas is transmitted to the grease through the piston, pushing the grease out of the tank body through the grease outlet and entering the equipment or parts that need lubrication. The position adjustment of the piston and the pressure adjustment of the compressed air jointly determine the output pressure and flow rate of the grease. Since the piston is used for pushing, there will be no problem of gas entering the grease to generate bubbles. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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.

[0022] like Figure 1-3 As shown, a technical solution provided by the utility model:

[0023] A grease supply system comprises a tank body 4; an upper cover plate 2 is arranged at the top of the tank body 4, a lower cover plate 6 is arranged at the bottom of the tank body 4, and a piston 8 is movably installed inside the tank body 4; compressed air inlets 3 are arranged at both ends of the upper cover plate 2, and grease outlets 7 are arranged at both ends of the lower cover plate 6; the two compressed air inlets 3 are connected to the inside of the tank body 4, and the two grease outlets 7 are connected to the inside of the tank body 4;

[0024] In this embodiment, the tank body 4 is in an empty tank state, the piston 8 is in the lowest position of the tank body 4, the grease outlet 7 is connected to an external pneumatic grease pump, and the valve on the pipeline between the pneumatic grease pump and the grease outlet 7 is opened. As the grease enters, the piston 8 will move upward. After the liquid level sensor 5 detects the piston 8, it stops pumping the grease, and then the compressed air inlet 3 is connected to the compressed gas. The grease pressure can be adjusted by adjusting the pressure of the compressed air. At this time, by adjusting the pressure at the compressed air inlet 3, the compressed gas enters the tank body 4 and applies pressure to the grease. The pressure of the compressed gas is transmitted to the grease through the piston 8, pushing the grease to flow out of the tank body 4 through the grease outlet 7 and into the equipment or parts that need lubrication. The position adjustment of the piston 8 and the pressure adjustment of the compressed air jointly determine the output pressure and flow rate of the grease. Since the piston 8 is used for pushing, there will be no problem of gas entering the grease to generate bubbles.

[0025] like Figure 1 As shown, a liquid level sensor 5 is provided on the outside of the tank body 4;

[0026] In this embodiment, the liquid level sensor 5 disposed on the outer wall of the tank body 4 is used to detect the position of the piston 8. When the position of the piston 8 is detected, the entry of grease can be stopped.

[0027] like Figure 2 As shown, a lifting ring 1 is movably installed on the top of the upper cover plate 2;

[0028] In this embodiment, a lifting ring 1 is movably mounted on the upper end of the upper cover plate 2, making the device more portable.

[0029] like Figure 3 As shown, sealing rings are sleeved on both the upper and lower sides of the outer wall of the piston 8;

[0030] In this embodiment, the sealing ring on the outer wall of the piston 8 is used to improve the sealing performance and prevent gas from penetrating into the grease below.

[0031] like Figure 3 As shown, the lower interior of the tank body 4 is funnel-shaped;

[0032] In this embodiment, the lower part of the interior of the tank body 4 is configured to be funnel-shaped to prevent grease residue.

[0033] Working principle: the tank body 4 is in an empty tank state, the piston 8 is in the lowest position of the tank body 4, the grease outlet 7 is connected to the external pneumatic grease pump, and the valve on the pipeline between the pneumatic grease pump and the grease outlet 7 is opened. As the grease enters, the piston 8 will move upward. After the liquid level sensor 5 detects the piston 8, it stops pumping the grease, and then the compressed air inlet 3 is connected to the compressed gas. The grease pressure can be adjusted by adjusting the pressure of the compressed air. At this time, by adjusting the pressure at the compressed air inlet 3, the compressed gas enters the tank body 4 and applies pressure to the grease. The pressure of the compressed gas is transmitted to the grease through the piston 8, pushing the grease out of the tank body 4 through the grease outlet 7 and entering the equipment or parts that need lubrication. The position adjustment of the piston 8 and the pressure adjustment of the compressed air jointly determine the output pressure and flow rate of the grease. Since the piston 8 is used for pushing, there will be no problem of gas entering the grease to generate bubbles.
