Description
Technical Field
[0001] The present application relates to the technical field of thrusters, and in particular to a linear thruster used for online refueling. Background Art
[0002] Linear thruster is a (mechanical) conversion mechanism that converts the rotary type of power into linear displacement. It is widely used in terminal actuators such as electric control valves and dampers in power generation, metallurgy, chemical industry, light industry, and urban water supply automatic control systems. Linear thruster is a conversion device that converts the multi-rotation torque of the actuator into linear thrust. Through the transmission of the screw nut, the screw is equipped with a plane bearing that can withstand thrust loads in both directions. It has the characteristics of high transmission efficiency and wear resistance. The push rod and the push seat adopt a piston structure with a small matching clearance and good straightness. It has obvious effects on the control of control valves and frequent control valves with high straightness requirements. It can accurately locate the scale of valve opening and accurately control the flow of pipeline fluids, which is conducive to the realization of full-process automated remote control.
[0003] In the related art, since an oil storage chamber is provided inside the linear thruster to maintain the lubrication state of key components, it is often difficult to replenish lubricating grease online in the oil storage chamber due to its working environment and the continuous operation state of the unit. This means that whenever the lubricating grease is insufficient, the operation of the unit must be suspended for oil replenishment, which not only increases maintenance costs but also reduces the efficiency of equipment use, so it needs to be improved. Utility Model Content
[0004] In order to solve the problem of inconvenience in oiling of traditional linear thrusters, the present application provides a linear thruster for online oiling.
[0005] The linear thruster used for online refueling provided in this application adopts the following technical solution:
[0006] A linear thruster used for online refueling comprises a screw sleeve and a T-shaped screw, wherein the T-shaped screw is arranged in the screw sleeve, an oil storage chamber is arranged in the screw sleeve, an oil injection channel is also opened in the screw sleeve, and the oil injection channel is connected to the inside of the oil storage chamber; an oil injection hole is opened at the bottom of the screw sleeve, and the oil injection hole is connected to the inside of the oil injection channel; a refueling nozzle is arranged at the opening of the oil injection hole.
[0007] Since the linear thruster is provided with an oil storage tank inside to maintain the lubrication state of key components, it is often difficult to add lubricating grease to the oil storage tank online due to its working environment and the continuous operation state of the unit. This means that whenever the lubricating grease is insufficient or needs to be replaced, the unit must be stopped for oil replenishment, which not only increases the maintenance cost but also reduces the efficiency of equipment use. By adopting the above technical solution, including the screw sleeve and the T-shaped screw, the oil storage chamber is formed in the screw sleeve, the oil injection channel is connected in the oil storage chamber, and the oil injection hole is connected to the oil injection channel, and the oil filling nozzle is installed at the oil injection hole. When the lubricating grease is insufficient, ensure that the online refueling operation is carried out under safe conditions, and prepare A good lubricating grease container (such as an oil barrel, oil gun, etc.) should be correctly connected to the oil filling nozzle to ensure that the connection is tight and there is no risk of leakage. Open the oil outlet valve of the lubricating grease container or start the oil pump and other equipment, prepare to start oiling, and inject the lubricating grease into the oil filling hole through the oil filling nozzle. At this time, the grease will flow into the oil storage chamber along the oil filling channel to realize the online refueling process. Through the setting of the oil filling channel, the oil filling hole and the oil filling nozzle, the lubricating grease can be replenished without stopping the machine, reducing the production interruption caused by oil replenishment due to shutdown, improving the use efficiency and production efficiency of the equipment, reducing the additional maintenance cost caused by oil replenishment due to shutdown, simplifying the oil replenishment steps, and making maintenance work more convenient and quick.
