Hengyang Heavy Industry Pneumatic Caliper Disc Brake QP25.4-D Mechanical Release Display

Pneumatic caliper disc brake PDA10. Pneumatic caliper disc brake PDB5. There are also applications. This method of connecting resistors in series is also commonly used in machine tools to limit the starting current during inching adjustment. The working process of the control circuit in Figure A is as follows: start the KT power on delay KM power on short circuit resistance according to the series resistance of the SBKM power on motor. When the motor runs normally, press SB, KM power off, its main contact is disconnected, and the motor stops. As long as KM is powered on, the motor can operate normally. But circuit diagram A has been powered on and operated continuously by KM and KT after the motor starts.

This product has the following advantages:

1、 The refined exterior design and innovative surface treatment of aluminum castings have brought customers a brand new visual effect, greatly improving the appearance and internal quality compared to steel castings, and reducing the weight of the entire machine.

2、 500000 reliability tests in harsh environments, comprehensive inspection and testing to ensure the reliability of every component and product before leaving the factory, and maintenance free for customers to use more confidently and safely. Therefore, we can propose a warranty period that exceeds twice that of similar foreign products to ensure effective use.

3、 The special heat treatment process for the aluminum casting of the front and rear covers of the air bag, as well as the machining method of the fully CNC lathe, controls the surface roughness of the air chamber machining to be above 0.4, greatly enhancing the long-term wear resistance of the front and rear covers, avoiding the wear of the "v" shaped sealing ring of the air bag during the working process, leading to air leakage, inability to open the brake, and the occurrence of malignant faults such as shutdown and production stoppage.
