Problems solved by technology

During the operation of the equipment, the transmission shaft has a free running area and moves in series along the axial direction. The shaft retaining ring will cause the edge of the axial end face of the bearing to wear. It is difficult for people to understand the amount of wear without detection instruments.
Using experience and regular maintenance will waste a lot of manpower and material resources, and accidents will easily occur if the maintenance is not timely

Embodiment Construction

[0019] Such as figure 1 , an isolated linear displacement transmission device shown in 2, 3 and 4 is characterized in that it includes a displacement sensor head, a guide magnet, a Hall sensor and a radiator shell that can form a magnetic circuit with an external measurement ring The sensor and a transmitter consist of a transmitter housing, a microcontroller containing a microprocessor, an LED display and an intelligent control module. The Hall sensor and the transmitter described therein are electrically connected through a shielded cable, and the hose and / or thread are hard-connected through a stainless steel hose and / or thread between the sensor and the transmitter housing; while the Hall sensor housing The other end is threaded to the pump cover and / or bracket. The external measuring ring is installed on the transmission shaft of the application equipment. When the equipment is running, the measuring ring will produce axial serial motion along with the transmission shaft...

Abstract

The invention discloses an insulating linear displacement transmitting device. The feature is that it includes hall sensor and a MCU, LED display and transmitter. The hall sensor and the transmitter are connected by shielded cable, and the shell of hall sensor connects to the shell of transmitter. The other end of hall sensor connects to pump cover and / or tray by thread. The invention would be installed on the shielded pump or magnetic drive pump under high temperature corrosion, inflammable and detonable circumstance. It could accurately measure the displacement of the axis, and display on LED or take alarming, machine halt, and / or realize tele-controlling of the secondary instrument.

Description

technical field [0001] The invention relates to measuring equipment characterized by adopting electric or magnetic methods, in particular to an isolated linear displacement transmission device adopting a Hall effect device. Background technique [0002] In high-temperature corrosion, toxic, flammable, explosive and other rotating closed equipment such as canned pumps and magnetic pumps, the drive shaft must use ring bearings made of wear-resistant materials. During the operation of the equipment, the transmission shaft has a free running area and moves in series along the axial direction. The shaft stop ring will cause the edge of the axial end face of the bearing to wear. It is difficult for people to know the amount of wear without testing instruments. It will waste a lot of manpower and material resources to adopt the empirical regular maintenance method, and accidents will easily occur if the maintenance is not timely. In view of this, design a measuring device characte...
