The invention belongs to the technical field of auxiliary equipment for UV gloss oil coating machines, and particularly relates to a UV gloss oil uncovering-free oil taking device for a coating machine. The oil drum opening device comprises a support, a feeding mechanism and a drum opening mechanism, the feeding mechanism and the drum opening mechanism are arranged at the top and the bottom of an oil supply position of the support respectively, the feeding mechanism moves an oil drum to the oil supply position, the drum opening mechanism comprises a drum breaking mechanism, an oil suction mechanism and a grabbing mechanism, and the grabbing mechanism grabs the upper edge of the oil drum at the oil supply position. The barrel opening mechanism comprises a barrel breaking cutter, a mounting plate and a lifting air cylinder, the barrel breaking cutter is fixedly connected to the middle of the mounting plate, the barrel breaking cutter is cylindrical, a wedge-shaped cutting edge is arranged at the bottom end of the barrel breaking cutter, and the oil inlet end of the oil suction mechanism penetrates through the middle of the barrel breaking cutter; the movable end of the lifting air cylinder is connected with the top of the mounting plate, and the fixed end of the lifting air cylinder is connected with the support. The convenience of taking oil from the packaging barrel can be effectively improved, and waste is reduced.

This utility model discloses an atomizing device and atomizing equipment with air exchange and no oil leakage. The atomizing device with air exchange and no oil leakage includes: a chamber body with an open lower end; a mounting component installed at the lower end of the chamber body to enclose and form an oil storage chamber, the mounting component forming a mounting chamber and an oil inlet channel connecting the mounting chamber and the oil storage chamber; a ceramic atomizing core installed in the mounting chamber, the upper side of the ceramic atomizing core communicating with the oil inlet channel, and the lower side enclosing the mounting component to form an atomizing chamber; wherein, the side wall of the oil inlet channel is provided with an air exchange port, the width of the air exchange port being 0.1-0.3 mm and the cross-sectional area being 0.01-0.09 mm². 2 The mounting components and the inner wall of the chamber form a ventilation channel with at least one bend. Both ends of the ventilation channel connect to the ventilation port and the atomizing chamber, respectively. This technical solution allows the gas in the atomizing chamber to replenish the upper side of the ceramic atomizing core, achieving pressure balance between the upper and lower sides of the ceramic atomizing core. This ensures that the oil can continue to enter the ceramic atomizing core normally, preventing clogging.

The present application belongs to the field of oil-free scroll compressor, and particularly relates to an electromagnetic controllable anti-self-rotation mechanism of an oil-free scroll compressor. The present application comprises a bracket in the shape of a groove, characterized in that: a movable scroll is arranged above the bracket, and a bearing blind hole is arranged on the bottom surface of the movable scroll; a bracket hole is arranged on the bracket at a position corresponding to the bearing blind hole in the middle, a plurality of electromagnet seats are arranged around the bracket hole, and a plurality of eddy current sensor seats are also arranged around the bracket hole; one electromagnet body is arranged on each electromagnet seat; one eddy current sensor body is arranged on each eddy current sensor seat; a groove is arranged below the movable scroll, and an armature is fixed in the groove; the electromagnet body, the eddy current sensor body and the armature are arranged in position cooperation. The present application can output clean high-pressure gas without oil.

This invention relates to the field of water conservancy engineering technology, specifically to a drainage system and method for a hydropower station. The drainage system includes a drainage pool, an upper partition, a lower partition, a lifting mechanism, a mounting frame, a rotating mechanism, multiple oil suction mechanisms, and an oil squeezing mechanism. The drainage pool is divided into a first chamber, a second chamber, and a third chamber by the upper and lower partitions. Clean water is injected into the first chamber until the liquid levels in the first and second chambers are level with the top of the lower partition. Oily wastewater is continuously injected into the first chamber, where floating oil is trapped, and oil-free water is discharged normally from the third chamber. After a period of time, the lifting mechanism moves multiple oil suction mechanisms down to the water surface to absorb oil, and then the rotating mechanism moves the multiple oil suction mechanisms to the upper oil squeezing mechanism to squeeze out the oil absorbed by the multiple oil suction mechanisms and collect it for discharge. This allows for the treatment of oily wastewater, separation of oil, and prevention of pollution to the downstream water environment.

The application relates to the technical field of petroleum engineering, and discloses an oil-free drag-reducing agent and application thereof, the oil-free drag-reducing agent comprising: ionic polyacrylamide, a polyether polyol compound, a suspending agent and an optional stabilizer; the weight ratio of the ionic polyacrylamide to the polyether polyol compound is 1:0.5-10; the weight average molecular weight of the ionic polyacrylamide is 5 million-30 million, and the average polymerization degree of the polyether polyol compound is less than or equal to 1000.The oil-free drag-reducing agent has excellent stability and will not settle for at least 9 months; the oil-free drag-reducing agent has good solubility, high solid content, good fluidity, can resist high salinity, and enriches the use scenarios of the oil-free drag-reducing agent; the oil-free drag-reducing agent does not contain an oil phase, is harmless to the formation environment, and simultaneously reduces the cost.

The application discloses a method and system for measuring the oil quantity of an irregular fuel tank of a ship, and belongs to the technical field of ship fuel management. The ship comprises a fuel main pipe, a ballast pipe, a seawater pump, a fuel injection pipe and a fuel tank. The method comprises the following steps: emptying the fuel in the fuel main pipe; starting the seawater pump to inject water into the fuel main pipe, and the water flows into an external storage tank through the fuel main pipe, the fuel tank and the ballast pipe in sequence, and the injection of water is stopped until the water in the external storage tank contains no oil; adding fuel into the fuel tank through the fuel injection pipe, and the fuel pushes the water in the tank to flow into the external storage tank through the ballast pipe, and the addition of fuel is stopped until the liquid flowing into the external storage tank through the ballast pipe becomes an oil-water mixture, and the reading of a flowmeter at this time is recorded; and the oil quantity is determined based on the reading of the flowmeter and the difference between the volume of the fuel main pipe and the ballast pipe. The method and system provided by the application can improve the measurement accuracy and reduce waste.
