This application relates to an oil-gas separator tank for marine compressors, belonging to the technical field of oil-gas separation systems. It includes a horizontally mounted tank body and a fixing plate for supporting the tank body. An inlet pipe and a first outlet pipe are fixedly mounted on opposite sides of the upper part of the tank body, respectively. A drain pipe is fixedly mounted at the lower part of the tank body. Several staggered isolation plates are fixedly mounted vertically on the inner wall of the tank body, and several isolation holes are evenly distributed on the isolation plates. A folding plate located below the opening of the first outlet pipe is fixedly mounted on the inner wall of the tank body. The folding plate is used to prevent oily gas from being directly discharged from the first outlet pipe. This application, through the staggered installation of isolation plates with isolation holes, can extend the flow path of oily gas within the tank body, increase the oil-gas separation time and opportunity, and improve the separation effect.

This application relates to the technical field of machine tool electric spindles, and discloses a milling machine tool electric spindle, a fault detection system, and a method. The milling machine tool electric spindle includes a stator, inside which a rotor is housed. Cooling chambers are provided at both ends of the stator, and flywheels are installed at both ends of the rotor, located inside the cooling chambers. The cooling chambers are connected by a connecting pipe, on which a circulation pump is installed. The rotor includes a central shaft and an armature winding mounted on the central shaft. A central coolant channel is provided within the central shaft, and coolant inlet and outlet channels are provided on the flywheels, communicating with the central coolant channel. A coolant branch channel is provided within the armature winding, communicating with the central coolant channel. A partition is provided in the middle of the central coolant channel. A speed sensor and a temperature sensor are installed inside the cooling chambers, and a vibration sensor is installed on the stator. This application has the effect of monitoring the working status of the electric spindle and preventing spindle damage.

This utility model relates to the field of drip irrigation tape technology, and more particularly to a self-cleaning drip irrigation tape with anti-negative pressure. The self-cleaning drip irrigation tape with anti-negative pressure includes a drip irrigation tape body, with mounting holes at the bottom of the tape body. A drip tray is fixedly installed in each mounting hole, and the drip tray has drip holes. A rotating disk is rotatably connected to the drip tray, and the rotating disk has drop holes corresponding to the drip holes. An impeller is installed on the rotating disk, and a cleaning pipe is connected to the drip irrigation tape body. The self-cleaning drip irrigation tape with anti-negative pressure provided by this utility model uses intermittent drip irrigation instead of continuous drip irrigation, which helps reduce soil surface moisture evaporation. Furthermore, the intermittent drip irrigation helps balance the pressure inside the pipe, thus preventing negative pressure. Opening the valve allows the angled nozzles to flush the drip irrigation tape body below, effectively removing accumulated impurities. This eliminates the need for frequent manual cleaning, reducing labor intensity and improving irrigation efficiency.

This utility model provides an electrically controlled thermostatic mixing valve core for a shower, relating to the field of shower valve core technology. It includes a linear motor connected to a piston, which is movably inserted into a mixing sleeve. The mixing sleeve has cold water inlets and hot water inlets near its two ends, and a plurality of water-blocking rings and a plurality of water-outlet rings are arranged alternately in the middle of the mixing sleeve. The advantages of this utility model are that it uses a linear motor to precisely adjust the piston's movement, completely eliminating manual temperature adjustment. This achieves precise adjustment with small torque and fine step distances, resulting in a stable and constant temperature, enabling accurate and intelligent temperature control and meeting users' needs for precise water temperature control.

The application discloses a liquid storage tank of an air conditioner and the air conditioner. The liquid storage tank comprises a tank body, a first liquid inlet, a first liquid outlet and an air hole on the tank body, a liquid processing part, a first switch part and an air permeable part. The liquid processing part is detachably arranged in the first liquid inlet. The first switch part is arranged on the first liquid outlet to control the opening and closing of the first liquid inlet. The air permeable part covers the air hole to connect the tank body with the external environment and limit the liquid in the tank body from flowing through the air permeable part. The application can filter and store the liquid generated by the operation of the air conditioner, and directly use the stored liquid for the new function of the air conditioner. Meanwhile, the liquid will not overflow when the liquid storage tank is taken out or put in, and the taking and putting is safer.

This invention discloses a vortex water tank with a constant temperature extrusion die, comprising a tank body, end plates fixed to both ends of the tank body, a sealing plate dividing the inner cavity of the tank into a vacuum section and a non-vacuum section, a top cover rotatably connected to the top of the tank body, and a sealing seat disposed in the non-vacuum section. The sealing seat has a through hole for the profile to pass through, and a water seal structure for forming a dynamic water seal is provided in the through hole. It also includes an extension cover, fixedly connected to the side of the sealing seat near the non-vacuum section, with its end rotatably connected to the sealing plate via a rotating shaft. By automatically releasing the sealing plate and opening the channel, the profile head can be smoothly output under the protection of the formed complete water seal. This avoids poor profile head shaping, dimensional fluctuations, and surface defects caused by insufficient vacuum or incomplete water seal establishment, thereby minimizing the waste length during startup and significantly improving material utilization and startup yield.

The present application relates to the technical field of interventional medical instruments, in particular to a pressure-controllable super-high-oxygen myocardial perfusion device and a pressure control method. The device comprises a normal-pressure oxygenation cavity, a heat exchange cavity and a high-pressure oxygenation cavity connected in sequence, and a main circulation loop and a static high-pressure oxygenation bypass; the inlet and outlet of the high-pressure oxygenation cavity are both provided with a blockage type peristaltic pump with pumping and sealing functions, the peristaltic pump is internally provided with an oxygenation membrane, and is configured with a pressurizing mechanism for simultaneously pressurizing liquid sides and oxygen sides on both sides of the oxygenation membrane, and a heat exchange mechanism for cooling the perfusion liquid to about 14 DEG C. The present application can prepare super-high-oxygen myocardial protective liquid with oxygen partial pressure higher than 700 mmHg through static, low-temperature and high-pressure oxygenation while maintaining extracorporeal circulation continuous perfusion, significantly improve the myocardial protection effect, and has the advantages of compact structure, precise control and safe operation.
