Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to the field of gate pumps, and particularly discloses a gate pump with a water-lubricated bearing. The gate pump comprises a body, the water-lubricated bearing is arranged in the body, the water-lubricated bearing comprises a bearing shell and a bearing lining, the inner surface of the bearing lining is provided with a water chute, an inner hole of the bearing lining is in clearance fit connection with a rotor shaft, a spiral groove is formed in the side wall of the rotor shaft, the groove comprises a connector connected with the exterior of the rotor shaft and a cavity formed in the rotor shaft, the connector is connected with the interior of the cavity, the side wall of the cavity extends towards the two ends of the rotor shaft, the bottom wall of the cavity is in an arc shape and protrudes towards the axis of the rotor shaft, and a baffle is arranged in the groove. A layer of lubricating water film is generated between the bearing lining and the rotor shaft under the action of high-speed shearing force of the rotor shaft, so that the cooling effect of the water-lubricated bearing is better, the friction coefficient between the water-lubricated bearing and the rotor shaft is also reduced, the power consumption of the pump is saved, and the efficiency ratio is improved.

Description

technical field [0001] The invention relates to the technical field of gate pumps, in particular to a gate pump with water-lubricated bearings. Background technique [0002] The integrated pump gate is a pump gate that integrates the pump station and the gate station. The integrated pump gate is composed of sluice gate, gate pump, flap gate, sensor configuration and a complete set of control system. The gate is not only the water retaining structure but also the foundation of the pump support. The water pump is arranged on the gate, and no fixed pump room is built, so that the gate and The two pumping stations are integrated into one, which greatly improves the flood discharge and water exchange capacity of the river, and avoids problems such as large footprint and long construction period. The main reasons and disadvantages of traditional gate pumps using oil-lubricated bearings are as follows: 1. In the case of traditional gate pumps using oil-lubricated bearings, in orde...
