Mine production brake shoe wear switch TE032, available from stock

Our company specializes in the production of mining brake shoe wear switches
This utility model provides a low-potential contact pin type brake shoe wear switch device, which consists of a contact pin electrode, an intermediate relay, a rectifier bridge, a control transformer, a time relay, and an indicator light. , buzzer composition, in which the output current of the control transformer is rectified by the rectifier bridge and the output is direct current. The negative pole of the DC current is grounded and the positive pole is connected to the contact pin electrode. There is a gap between the contact pin electrode and the brake disc. The alarm relay controls the opening of the time relay and the sound and light alarm circuit. The closing indicator light and buzzer are connected in parallel, which has the characteristics of high reliability and safety, can prevent electric shock and reduce personal injury.

The brake shoe wear switch is a mechanical switch dry contact designed specifically for detecting and controlling the brake shoe gap of the elevator disc brake. The output form can complete the detection of brake shoe clearance (using normally closed contacts) and monitoring of disc spring fatigue damage (using normally open contacts). After being applied to the elevator disc brake, it can be directly connected to the

> for monitoring. When there is a safety problem, it can automatically sound and light alarm. In addition, it can also be connected to the electronic control. The system can automatically power off the electronic control when encountering safety issues. Such a setting can meet the requirements of the "Coal Mine Safety Regulations" regarding the control of brake shoe clearance.

The winch braking device is an important part of the mining winch. The correctness of brake shoe wear protection is directly related to the operational safety of the winch. The "Coal Mine Safety Regulations" require that when the wear gap of the brake shoe exceeds the specified value, it can automatically alarm or automatically cut off the power.
