Six CQP30-D springs for Hengyang Heavy Industry pneumatic caliper disc brake

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.

4、 The ingenious design and use of fully imported Italian "v" type seals enable the air bag to quickly expand without leakage during intake and contract in a timely manner during exhaust, ensuring smooth exhaust without resistance. This completely solves many problems such as seal wear, leakage, reduced braking force, and scrapping of the air bag after a short period of use.

5、 The air bag piston rod undergoes multiple processes of processing, wear-resistant plating and polishing treatment, with a beautiful appearance and no wear on the "v" type seal. Strict tolerance fit and concentric requirements are required for the front cover, shaft sleeve, piston rod, piston disc, etc. The clearance between the piston rod and shaft sleeve is 0.02-0.03mm on one side, allowing the entire piston to move flexibly and effectively ensuring the working thrust of the air bag.
