Description
Technical Field
The invention belongs to the technical field of sewage pumps, and particularly relates to a pump shaft bearing quick-release structure.
Background
The submersible sewage pump is a pump product which is connected with a motor and simultaneously submerged to work under liquid, and compared with a common horizontal pump or a vertical sewage pump, the submersible sewage pump has the advantages of the following aspects:
(1) compact structure and small occupied area. The submersible sewage pump can be directly installed in a sewage pool because of submerged operation, a special pump room is not required to be built for installing the pump and the machine, and a large amount of land and capital construction cost can be saved.
(2) The installation and the maintenance are convenient. The small submersible sewage pump can be freely installed, the large submersible sewage pump is generally provided with an automatic coupling device to be automatically installed, and the installation and the maintenance are quite convenient.
(3) The continuous operation time is long. The submersible sewage pump has the advantages that the pump and the motor are coaxial, the shaft is short, the weight of rotating parts is light, so that the load (radial direction) borne by the bearing is relatively small, and the service life is much longer than that of a common pump.
(4) The problems of cavitation damage, irrigation and water diversion and the like do not exist. Particularly, the latter point brings great convenience to operators.
(5) The vibration noise is small, the temperature rise of the motor is low, and the environment is not polluted.
Because of the advantages, the submersible sewage pump is more and more emphasized by people, the use range is wider and wider, and the submersible sewage pump can be used for conveying various domestic sewage, industrial wastewater, drainage of construction sites, liquid feed and the like from the original pure conveying of clean water to the present. Plays an important role in various industries such as municipal engineering, industry, hospitals, buildings, restaurants, water conservancy construction and the like.
However, although the existing submersible pump has the advantages, the existing submersible pump has the disadvantages that the sewage pump is under liquid; the conveyed medium is a mixed liquid containing solid materials; the pump is in close proximity to the motor; the pump is arranged vertically, and the weight of the rotating part and the water pressure borne by the impeller are in the same direction. These problems all make the sewage pump have higher requirements in the aspects of sealing, motor bearing capacity, bearing arrangement and selection, and the like than the common sewage pump. Therefore, the dredge pump is inconvenient to overhaul because large tools such as a wheel puller for disassembling a bearing on a pump shaft are required to be taken.
