QPD □, cqpd □ series pneumatic caliper disc brake

Application:



QPD □, cqpd □ series pneumatic disc brakes are widely used in parking braking or deceleration braking of small and medium-sized drive mechanisms. The tensioning and braking of the winding mechanism, such as the tensioning of paper in the paper mill, the tensioning control of newsprint during News printing, the unfolding and tensioning of steel plate (steel wire) roll, wire and cable paying off, cable paying off and tensioning control, etc.



Compliance with standards:



The technical requirements of caliper disc brake shall comply with JB / t10917-2008 standard.



Main features:



▲ QPD □ series is normally closed design: spring braking, pneumatic release (opening); Cqpd □ series is normally open design: pneumatic braking, spring release, braking force can change with the change of air pressure, and can be changed flexibly according to needs during use;



▲ compact structure, small volume, sensitive action, light weight and convenient use;



▲ snap on asbestos free brake pad, green and environmental protection, convenient and fast replacement;



▲ installation mode: suitable for horizontal axis or vertical axis braking mode. In the horizontal axis braking mode, it can be installed at any angle around the brake disc, but it is better to install horizontally; In the vertical axis braking mode, the angle is unlimited. One brake disc can be installed with one brake or two or more brakes, but it is recommended to install two or more brakes symmetrically as far as possible;



▲ all power sources do not need to be set separately, and can be connected with the existing air compressor station. Speed regulating valve is installed in the gas supply line, and the braking time can be adjusted steplessly.



Working conditions:



◆ ambient temperature: - 20 ° C ~ + 40 ° C;



◆ maximum working pressure: 7 bar;



◆ air source requirements: the compressed air entering the air bag shall be dry and clean, and shall not contain corrosive gas;



◆ if there are special requirements, they shall be determined through negotiation when ordering.



Basic parameters:



● product model: QPD □, cqpd □
