Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 9 A vane-type seawater pump shown includes a front flow plate 1, a stator 2, and a rear flow plate 3 connected in sequence. The high-pressure oil port channel 4 and the low-pressure oil port channel 5 connected with the oil suction port of the pump body, when working, the high-pressure oil is discharged to the oil discharge port through the high-pressure oil port channel 4, and the low-pressure oil in the oil suction port is sucked by the low-pressure oil port channel 5 . Specifically, a front end cover 6 is fixedly connected to the front distribution plate 1, and a rear end cover 7 is fixedly connected to the rear distribution plate 3; The oil suction port channel 62, the end face of the rear end cover 7 facing the rear distribution plate 3 are respectively provided with a rear high pressure oil chamber 71 and a rear oil suction po...

Abstract

The invention discloses a blade type sea water pump. The blade type sea water pump comprises a front port plate, a stator and a rear port plate, wherein the front port plate and the rear port plate are arranged at a high-pressure oil port channel communicating with an oil discharge outlet, and a low-pressure oil port channel communicating with an oil suction opening in a matched manner; a rotor is arranged in the stator; a plurality of blades are arranged between the rotor and the stator; a plurality of cylindrical grooves which are in one-to-one correspondence to the blades are formed in the outer peripheral wall of the rotor in the axial direction; cylindrical joints which are matched with the cylindrical grooves are arranged at inner ends of the blades; the blades are in running fit with the rotor through the cylindrical joints; trunnions are respectively arranged on two sides of the outer end of each blade; a rolling bearing is assembled on each trunnion in an interference manner; annular grooves are respectively formed in the front port plate and the rear port plate; the corresponding rolling bearings can be mounted in the annular grooves; and when the blades rotate along with the rotor, the trunnions drive the rolling bearings to roll around the annular grooves. The blade type sea water pump is compact and reasonable in structure, convenient to machine, small in abrasion, stable and reliable in working performance and relatively long in service life.

Description

technical field [0001] The invention relates to the technical field of seawater pumps, in particular to a vane type seawater pump. Background technique [0002] The 21st century is the ocean century, and the development of marine technology and high-tech equipment is particularly important. Seawater hydraulic technology is an important field of marine engineering technology. However, it has been restricted by factors such as corrosion and materials for a long time, making the development of seawater hydraulic technology relatively slow, especially in terms of seawater power source-seawater pumps. [0003] The structure and principle of the seawater pump are basically the same as the traditional hydraulic pump. The structure of the common vane seawater pumps currently on the market usually includes a front distribution plate, a stator and a rear distribution plate connected in sequence. The front distribution plate and the rear distribution plate are equipped with a high-pre...
