QP12.7 Pneumatic Brake

QP12.7 pneumatic inlaid disc brake friction plate is an advanced product that not only has the advantages of disc brake, but also has extensive adaptability and unique advantages. This product has the characteristics of simple structure, small size, light weight, high reliability, using compressed air as the power source, convenient use, suitable for multiple disc diameters, convenient installation, debugging, and maintenance. Widely used for deceleration and braking of fixed operating mechanisms such as metallurgy and bulk loading and unloading;

QP12.7 Pneumatic brake QP12.7 Pneumatic inlaid disc brake has QP12.7-A, QP12.7-B and other specifications. One disc diameter of each type of brake can be adjusted for four levels of braking torque. The matching air bag adopts imported aluminum alloy air bag, which has reliable and stable performance, good sealing performance, small size and light weight. It can be divided into Type A and Type B according to the use performance requirements;

QP12.7 Pneumatic Brake

1、 Working principle

QP12.7 pneumatic brake QP12.7 pneumatic caliper Disc brake frame and cylinder are composed of two parts (see the structure diagram). When cylinder 1 is filled with pressure air, piston rod 5 quickly contracts into the cylinder under the action of air pressure. The left and right brake arms, under the action of return spring 4, drive the friction block 12 to quickly open (i.e. release the brake). When the cylinder stops supplying air and quickly deflates through the control valve, the piston rod 5 quickly extends under the internal spring of the cylinder, pushing the left and right brake arms to drive the friction block 12 to close (i.e., the holding brake).

QP12.7 Pneumatic Brake II. Installation of Brake

1. Firstly, check the brake surface of the brake disc and brake pad for oil sludge or other stains.

2. Install the G3/8 "(cast iron rod cylinder) or 1/2" (cast aluminum cylinder) connector on the air inlet of cylinder 1, connect the air pipe with a hose, and the air source should be free of oil, water, and other impurities

QP12.7 Pneumatic Brake 3. When installing, first introduce pressure air to retract the piston rod 5 into the cylinder. Then, install the friction block 12 into the brake disc in the direction perpendicular to the brake disc. Then, fix the base 9 horizontally on the rigid base so that its center is in line with the thickness center of the brake disc. The installation position dimensions are shown in the structural diagram

QP12.7 Pneumatic Brake III. Adjustment

a) Adjust the air pressure value to a range of 5-7 bar.

b) For normal work, the first step is to test the brake several times and check if there are any abnormalities in the brake.

c) The retraction distance of the friction block can be adjusted by rotating the adjustment rod 6 to change the size of the working stroke. When rotating the adjustment rod, pressure air is first introduced to retract the piston rod, and then adjusted.

QP12.7 Pneumatic Brake IV. Maintenance

When the friction plate of QP12.7 pneumatic brake is worn and the working stroke increases to 8mm, it is necessary to immediately adjust the rod 6 to readjust the working stroke by about 4mm. Otherwise, the brake will fail. After adjustment, the nut 7 should be tightened. When the friction block 12 is worn to about 6mm, the wear block needs to be replaced. The replacement steps are as follows:

QP12.7 Pneumatic brake 1, cylinder,

2. Right brake arm

3. Return spring

5. Piston rod

6. Adjusting the lever

7. Nut

8. Left brake arm

9. Base

10. Brake pads

11. Spring steel wire

12. Friction block

QP12.7 Pneumatic Brake Application:

QP12.7 Pneumatic Brake QP series pneumatic caliper disc brake is mainly used for braking and deceleration of various mechanisms in hoisting, transportation, metallurgy, mining, port, construction and other machinery, as well as tension control of machinery such as cable, paper making, steel plate and so on.
