Embodiment Construction

[0017] A shaft coupling shield for a pump, comprising a hollow body 1, which is located at both ends of the body and a connecting part through which the shaft of the coupling passes. The material of the shaft coupling shield for the pump is plastic, so it has The advantages that metal materials do not have such as no rust and corrosion resistance make the pump coupling protective cover have a long service life in harsh working environments.

[0018] As shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the coupling shield for the pump is respectively provided with end faces 2 at both ends of the main body 1, and the end faces 2 are sealed and connected with the main body 1, and on the top of the end face 2 There is a through hole 3, which can allow the coupling to connect with the shaft of the motor or pump. The two end faces 2 with through holes 3 will not affect the work of the coupling, but can prevent some debris from entering The inside of...

Abstract

The invention relates to a protective casing of a pump coupling, which is made of plastic and is rustless and corrosion resistant. The invention has the long service life even in the harsh working environment. The protective casing of the pump coupling is provided with two end faces which have a seal connection with the body. The end faces are provided with a through hole, the shaft of the coupling can drill through the through hole. The invention can prevent sundries from entering into the protective casing and protect the coupling well.

Description

technical field [0001] The invention relates to a shaft coupling protective cover used on a pump. Background technique [0002] Due to the leakage of chemical media in many pumps or other equipment, it is easy to cause the air to be filled with various chemicals, such as acid mist, etc., causing the coupling to corrode and rust. Therefore, a protective cover is required to protect the coupling. Most of the current coupling guards for pumps are made of metal, and the structure usually includes a hollow body, and the two ends of the body are open to allow the coupling to be connected with the shaft of the pump or the motor. This kind of coupling protective cover is easy to rust in the harsh working environment, and some are even corroded and perforated, and the service life is short; to better protection. Contents of the invention [0003] The purpose of the present invention is to provide a protective cover for a shaft coupling for a pump. The protective cover for a shaf...
