The self-cleaning valve element has the advantages that the fan blades are impacted by oil liquid to rotate, then the scraping rod is driven to continuously rotate, the scraping rod can continuously clean the inner wall of the shell, impurities cannot stay on the inner wall of the shell, self-cleaning of the shell is achieved, the interior of the shell is kept clean, and normal use of the valve element is not affected; and manual regular cleaning is not needed, so that the use is more convenient.

The invention provides a fan provided with an oil bearing. The fan provided with the oil bearing comprises a casing, the oil bearing, a sealing oil cover, a stator and a rotator which can rotate relative to the stator; the casing comprises a shaft seat; the stator is sleeved to the periphery of the shaft seat; the oil bearing is accommodated inside the shaft seat; the sealing oil cover is arranged at the bottom of the oil bearing; lubricating fluid inside the oil bearing is sealed inside the shaft base; the rotator comprises a hub, fan blades and a rotating shaft which is arranged inside the oil bearing and can rotate relative to the oil bearing; the hub is arranged on the periphery of the stator; the fan blades are arranged on the periphery of the hub in a ring mode; the rotating shaft vertically extends towards the shaft base from the hub center; a plurality of sinking grooves are formed in the bottom of the outer circumference of the oil bearing. The fan provided with the oil bearing has the advantages of prolonging the service life due to the facts that part of spare lubricating oil is stored inside the sinking grooves which are formed in the bottom of the outer circumference of the oil bearing and the spare lubricating oil is automatically supplied when immersion oil precipitation inside the oil bearing is deficient.

The invention discloses a bearing grease return structure comprising an annular bearing ring cavity arranged outside a bearing in a surrounding mode. The bearing ring cavity communicates with the bearing so as to receive grease lubricating the bearing. A grease return pipe set is connected to the bearing ring cavity and is connected with a grease return pump. The grease return pipe set is used forguiding grease entering the bearing ring cavity into the grease return pump when an engine works normally, and for storing grease after the engine is stopped so as to prevent the grease from being held in the bearing ring cavity. In the bearing grease return structure, no large-volume grease receiving pool structure is needed, therefore no large installing space is needed in a case, the structureof an original engine is not changed, and the number of engine parts and the weight of the engine are not increased. In addition, after the engine is stopped, the bearing grease is stored in the grease return pipe set away from the turbine end, no grease is in the bearing ring cavity, thus grease coking in the bearing ring cavity can be avoided effectively, and then work performance of an enginelubrication system is improved greatly.

The invention discloses a butting octagonal frustum pyramid type floating production and oil storage system. A floating body of the butting octagonal frustum pyramid type floating production and oil storage system is provided with an upper structural body in an octagonal frustum pyramid shape and lower structural body in a regular octagonal frustum pyramid shape. Under a combined state, the bottom face, with a small area, of the upper structural body is fixedly connected with the bottom face, with a small area, of the lower structural body to form a connecting surface. The axis of the upper structural body and the axis of the lower structural body are arranged in an identical straight line, the bottom, with a big area, of the upper structural body is an upper deck of a floating structure, and the bottom, with a big area, of the lower structural body is a lower bottom of the floating structure. The connecting surface is the full loading water plane line of the floating structure. On the basis of the mentioned structure, a mooring locating module, an oil and gas production module, a storage module, an outward conveying module and other function modules are arranged to form a novel floating type production and oil storage system. The floating body has the appearance characteristics similar to a hourglass, the butting octagonal frustum pyramid type floating production and oil storage system can make up the defects of a traditional floating production and oil storage system at the aspects of seakeeping performance, strength fatigue, pipeline layout and the like, and the functions of the butting octagonal frustum pyramid type floating production and oil storage system are expanded.

The invention discloses a motor with oil storage funciton. The motor includes a base, a bearing, a stator unit and a rotor. The base includes a shaft tube portion having a closed end and an open end. The bearing is received in the shaft tube portion of the base. The stator unit is fixed to the base and has an insulation unit. The insulation unit has a blocking portion extending towards the open end of the shaft tube portion. The rotor includes a hub having a shaft and a permanent magnet. The shaft is rotatably coupled with the bearing, and an air gap is formed between the permanent magnet and the stator unit. The blocking portion of the insulation unit, the shaft tube portion and the bearing jointly form an enlarged oil chamber at the open end of the shaft tube portion. With the above design, the shaft tube portion can have more space to form an oil-storing structure for accommodating more lubricating oil.
