Butter injector (4 images) A butter injector, also known as an oil filler or dosing machine, is a pressure-enhancing device specifically used to inject butter into lubrication stations. It is widely used in industries such as machine tools, equipment, automobiles, and ships. 　　With the continuous development of industry, greater attention than ever has been paid to the use of lubricants, which play an important role in machinery. Traditional butter guns that rely on arm strength to apply pressure can no longer meet the demands of modern times. How to provide better lubrication and maintenance services for machine tools, equipment, automobiles, ships, etc. has become the mission of the grease gun industry, especially given the higher pressure requirements for greasing. The pressure ratio of the pneumatic butter gun is now 40:1 ； 50:1 ； 60:1, with an oil discharge pressure as high as 24-48 MPa, which is equivalent to 240 Kg-480 Kg of force. 　　Currently, some of the more influential butter machine brands in the international market include RAASM from Italy, Lincoln and Ingersoll Rand from the United States, YAMADA from Japan, as well as Jiulong and Wending from Taiwan. The domestic manufacturers of butter machines are of mixed quality. Types Butter pumps are mainly classified as follows: 1. Pneumatic butter pumps ； 2. Manual butter maker ； 3. Foot-operated butter churn ； 4. Electric butter mixer ； 5. Butter gun. 　　The most commonly used device is the butter gun, but in many applications, the household-type butter guns that rely on arm pressure are far from sufficient to meet industrial standards. As a result, in various industrial sectors such as manufacturing, mining, machine tool manufacturing, the automotive industry, and the shipbuilding industry, pneumatic butter guns are increasingly being adopted. Working principle: The high-pressure pneumatic oil injector is a device that combines an air pump with a plunger pump; it is referred to as an oil injection pump. It consists of components such as an oil storage tank for storing butter, an oil injection gun, high-pressure rubber hoses, and quick-release connectors. 　　A high-pressure pneumatic oil injector is an oil injection pump that combines an air pump with a plunger pump; it consists of components such as an oil storage cylinder for storing butter, an oil injection gun, high-pressure rubber hoses, and quick-connect fittings. 　　(1) The upper part of the oil injection pump serves as an air pump; compressed air enters the air distribution chamber, and through devices such as sliders and slide valves that control the direction of airflow, the air is directed either to the upper or lower end of the piston in the cylinder. This allows the piston to automatically switch between intake and exhaust processes over a certain stroke distance, thereby enabling reciprocating motion. The lower part of the oil injection pump is a plunger pump, which is powered by an air pump; the two are connected by a connecting rod and perform reciprocating movements in sync with the air pump. The plunger pump contains two check valves; one is fitted over the lift rod and is known as a four-foot valve disc, which provides axial sealing with the lift rod ； Another is a nylon piston at the oil discharge port at the end of the plunger rod, which achieves a linear seal with the discharge valve seat via its conical surface; both of them operate back and forth in synchronization with the oil injection pump. As the plunger rod moves upward, the nylon plunger closes, and the material-lifting rod, connected to the material-lifting plate, lifts the oil upward; the oil then pushes open the four-legged valve to flow upward into the pump ； As the plunger rod moves downward, the four-legged valve closes downward; the oil inside the pump is compressed by the plunger rod, which in turn opens the nylon piston valve to allow oil to be discharged again. In this way, as long as the oil pump moves up and down back and forth, high pressure can be generated to facilitate the discharge of oil. 　　(II) The oil storage cylinder is equipped with a rubber-sealed piston; under the pressure exerted by the screw, this piston is continuously pushed toward the oil surface, thereby preventing contamination and keeping the oil clean. 　　(III) The oil injection gun is a tool used in the oil injection process; it transports the high-pressure oil discharged by the pump through a high-pressure rubber hose to the gun, where the nozzle of the gun comes into direct contact with the area that needs to be filled with oil. By pulling the trigger, the oil is injected into the desired location.
