Jiaozuo brake

There are two types of disc brake structures: normally open and normally closed. The structure of a normally open point disc brake for loaders. The brake consists of a caliper (1), a piston (2), a brake disc (3), a brake disc (4), and a sealing ring (5). When pressure oil enters the cylinder and pushes the piston towards the brake disc, braking is achieved. There are two types of automatic adjustment for brake release (or piston return) and clearance after wear: sealing ring type and spring type. Because the brake clearance of the point disc brake is very small (about 0.1mm on each side), when the brake pushes out the piston, the friction forces the seal ring to deform. When the brake is released, the oil in the cylinder is depressurized, and the piston automatically resets due to the elastic force caused by the deformation of the sealing ring. If the brake clearance increases due to the wear of the friction lining, the piston movement will be greater than the deformation of the sealing ring, thus overcoming the friction force. The piston will move outward relative to the sealing ring until the brake disc is compressed. When releasing the brake, the elastic force of the sealing ring causes the piston to return to its original position. The return distance is not the original piston extension distance, but only the size of the deformation of the sealing ring, in order to achieve the goal of automatically adjusting the brake clearance

The QP (CQP) series pneumatic caliper disc brakes are mainly used in lifting, transportation, metallurgy, mines, and ports

Braking and deceleration of various mechanisms in machinery such as Kou and construction.

Usage conditions

Environmental temperature: -5 ℃~40 ℃

Working air pressure: 5-7bar for QP series;

The CQP series is ≤ 7bar.

Outdoor rain and snow erosion or corrosive gases and media should be corrosion-resistant products.

The air source should not contain oil, water, or other impurities.

main features 

The QP series adopts spring braking and pneumatic release; CQP12.7 pneumatic caliper disc brake is pneumatic brake with spring released.

The overall structure is simple, small in size, and lightweight.

Asbestos free brake pads, green and environmentally friendly.

The installation of the brake pad adopts a spring clamp type, which is convenient and fast to replace.

The brake pad is easy to adjust after being worn.

Each disc diameter of the QP series brake can be adjusted for four levels of braking torque.

All power sources do not need to be set separately and can be connected to the existing air compression station for grid use. They can be added to the gas supply line

Equipped with a speed control valve, the braking time can be adjusted steplessly.

Note: 1. It can produce pneumatic caliper disc brakes with different disc thicknesses and installation sizes.

2. The specific model and structural dimensions reserve the right to change. The characteristic of brakes is high efficiency. The brake chamber has a small size and fast charging and discharging response. Energy saving and automatic adjustment mechanism with clearance ensures good braking force matching, directional stability, and braking stability during use. The floating brake structure is adopted, which ensures stable braking torque output, good braking follow-up, and can reduce noise and alarm. Due to the small diameter of the brake drum, wide friction plate, and good heat dissipation conditions, the thermal stability is improved, and high-speed braking performance is improved. It also creates conditions for using small tires with fewer types of parts, The number of parts is also small, with good interchangeability and versatility, facilitating serialization and low quality.

For example, transmission equipment in steel and metallurgical workshops, we know that both indoor and outdoor work have unique characteristics and problems. If the problem cannot be solved, it will affect its normal use. What we want to say here is the port crane. We know that the port is relatively open, and the wind is usually strong due to the influence of the sea, and the crane will be blown over in case of severe wind. At this time, to ensure the normal operation of the crane, it is necessary to install wind brake, thruster, electric hydraulic brake, hydraulic brake, hydraulic thruster, ED electric hydraulic thruster, ED thruster, explosion-proof thruster, disk brake, Electromagnetic brake, brake shoe, brake accessories, brake manufacturer, brake price, Jiaozuo brake, Jiaozuo brake, Jiaozuo brake factory, Jiaozuo hydraulic brake factory, brake manufacturer, crane brake, thruster brake, YT1 actuator, explosion-proof brake, wind brake, electromagnetic brake mainly produces YWZB, YWZ2, YWZ3, YWZ4, YWZ5, YWZ6, YWZ8, YWZ9, YWZ10, YWZ12 YWZ13 series electric hydraulic block brake. All kinds of explosion-proof brakes, TJ2 series new energy-saving electromagnet brakes, electro-hydraulic arm disc brakes, mine explosion-proof electromagnetic starters and mine vacuum feed switches have complete specifications, reliable performance and high quality
