The invention relates to a precognition type electronic speed regulator of a generator set and a speed regulating method thereof. The precognition type electronic speed regulator of the generator set is characterized in that a current sampling circuit sampling the currents of the generator set is added on the basis of the traditional device, and a microprocessor monitors generator set current sampling signals transmitted by the current sampling circuit in real time; when the generator set current sampling signals are suddenly substantially increased, the microprocessor immediately controls and increases the oil supply quantity of a motor so that the motor of the generator set have sufficient capability to prevent rotating speed from being substantially decreased because loads are suddenly increased; with such a same way, when load currents are substantially decreased, the precognition type electronic speed regulator can start to substantially decrease fuel oil supply before the rotating speed of the motor is not increased to prevent the rotating speed from being substantially increased because the loads are suddenly unloaded so that the loading capability of the generator set is enhanced and the synchronous motor loading capability is enhanced especially, and therefore, the precognition type electronic speed regulator can control the fluctuation rate of the rotating speed of the motor to be kept in an optimal state under any loading condition.

The invention provides a wear-resistant bush, which relates to the field of mechanical parts. The wear-resistant bush includes a bush main body, and the inner wall of the bush main body is provided with a plurality of lubricating oil passages extending in a spiral shape; a plurality of The starting ends of the lubricating oil passages are evenly arranged along the circumference of the bushing body; the pitches of the plurality of lubricating oil passages are respectively equal; the plurality of lubricating oil passages intersect each other; the plurality of lubricating oil passages The beginning and the end of the passage are closed respectively; the bushing body is also provided with an annular oil storage passage, and the rotation axis of the oil storage passage is collinear with the rotation axis of the bushing main body; the oil storage passage and the The plurality of lubricating oil passages are connected through respectively. The wear-resistant bush provided by the invention solves the technical problems of the traditional bush such as uneven distribution of oil passages, insufficient oil supply and poor sealing performance.

The invention discloses a low-back-pressure horizontal compressor and a refrigerating system. The compressor comprises a shell and a compressing mechanism, wherein the shell is provided with an air suction pipe and an air discharging pipe, and a low-pressure oil pool is arranged at the bottom of the shell; the compressing mechanism comprises two air cylinder, two fitted bearings, two cover plates, a crankshaft and a rolling bearing, the cover plates are respectively arranged at the sides, facing to each other, of the two air cylinders, the two fitted bearings are connected through a retainer to define a closed air discharging cavity, the crankshaft is matched with the two fitted bearings, the rolling bearing is arranged between at least one fitted bearing and the crankshaft, the part, which is provided with the rolling bearing, of the fitted bearing is matched with the crankshaft in a sliding manner, a central hole is formed in the crankshaft, a plurality of radial holes are formed in the crankshaft and are communicated with the central hole, the central hole is communicated with the low-pressure oil pool through an oil supplying pipe, and each fitted bearing and at least one radial hole are correspondingly arranged. The compressor provided by the invention is beneficial to increasing oil supplying amount and alleviating the abrasion of the fitted bearings.

The invention relates to a grease plunger pump. The grease plunger pump comprises a driving device, a grease stirring device, and a grease absorption and discharging device, wherein the grease absorption and discharging device comprises a pump body and a swing device; the pump body comprises a cylinder and a plunger movably arranged in a plunger chamber of the cylinder; the swing device comprises a swing main body which can do reciprocating motion axially relative to the plunger chamber of the cylinder; and a non working end face of the plunger is fixed on the swing main body and do reciprocating motion synchronously in the plunger chamber along with the reciprocating motion of the swing main body so as to absorb and discharge the grease. The swing main body is provided with a first through hole which is parallel to a rotation shaft of the driving device; the cylinder is provided with a second through hole which is parallel to the rotation shaft of the driving device; the rotation shaft of the driving device passes through the first through hole and the second through hole; and the end part drives the grease stirring device to circumferentially rotate so as to stir the grease. The connection parts between the driving device and the grease stirring device are simplified, the structure of the plunger pump is more compact and reasonable, the loss of the energy is reduced, the structure of the grease absorption and discharging device is not influenced, and the plunger pump has large grease supply.
