Pneumatic caliper disc brake QP12.7 QP15 QP20 CQP25.4-D QP30-D

By changing the air pressure, subtle torque adjustment of the machinery becomes possible.

(1) Prevention of overload of the gate (2) Tension control (3) Soft start, smooth stop, etc., with good accuracy implementation

3. Pneumatic safety

No electrical sparks generated

Due to not using electrical equipment, there is no electrical spark generated, which is reassuring

Non asbestos friction plate

Grinding edges does not use asbestos at all, achieving good wear resistance and heat resistance.

4. Be slow and at ease

High-speed actuation

Compared to electromagnetic type, the response speed is 20% faster

Smooth combined braking

The adjustment of the communication bureau is very simple, allowing for smooth power connection and braking.

The smooth operation enhances the durability of the machinery and generates great value.

5. Long service life and simple maintenance

Long lifespan

The heat release effect is good, and the thickness of the friction plate is very generous. Compared with the electromagnetic type, the lifespan is 2.5 to 5 times longer.

Easy installation and operation

Due to its simple and integrated construction, installation and operation are both simple

The exchange of friction plates is simple

Two parallel long tracks are formed by overlapping movable arms on both sides of the car, which are unloaded one by one onto the mining car by a warehouse type trolley with four rollers, which is filled with minerals. The capacity of a warehouse type trolley can be equal to or half of the capacity of a mining car; Every time a mining truck is fully stored, the warehouse type trolley will make one or two round-trip trips. Using this type of train in the excavation of single track single end tunnels can save a lot of shunting time. A fully steel structure mining car with two sleeve connected cylinders installed on both sides of the lower part of the pneumatic self dumping car body; There are two types: narrow gauge and quasi gauge. When using this type of mining truck. The bucket type transfer train must be equipped with an air compressor when connecting several mining cars in series on the traction locomotive or at the unloading site. When the cargo needs to be overturned, compressed air is introduced into the cylinder. For mines with unified compressed air pipeline networks, pipeline compressed air can also be used for unloading work. This type of mining car has a long service life and a small maintenance workload

Due to the obvious advantages of the disc brake, there is a trend to replace the block brake on some equipment. Former West German companies such as BUBENZER, KRUPP, and DEMAG all have a series of production crystals for this type of brake. For example, BUBENZER has multiple series such as SKP, SKD, and SB. In 1980, the former West Germany formulated a draft of relevant standards for disc brakes, which was revised in 1989 to gradually standardize the design and manufacture of disc brakes. Several companies in Japan also produce disc brakes, such as Sumitomo Electric, which uses British technology to produce MK series disc brakes, and Japan Co., Ltd. and BUBEN.ZER jointly produce sB series disc brakes. The former Soviet Union, the United States and France also produced disc brakes. In recent years, many of the various hoisting machinery, metallurgical machinery, ship unloaders, large excavators and other equipment imported from China use disk brakes. For example, the crane running mechanism of the Overhead crane imported from Japan by the hot rolling plant of WISCO uses a normally open pedal hydraulic disk brake, The Overhead crane introduced from France by Qinshan Nuclear Power Station uses the disc brake as the safety brake. The working principle of the pneumatic brake is to input pressurized gas into the air chamber of the pneumatic brake, so as to drive the piston to move in a straight line, so that the friction block of the brake can lower the brake and press the brake wheel to produce friction and brake. The pneumatic brake is connected by air pressure, released by a reset spring, and the disc slides along the axis with air pressure to contact the friction plate. Discs, friction plates, etc. are assembled onto the wheel hub to form an integrated structure. The friction plate can be disassembled by unscrewing the adjusting nut, and the exchange is simple. Pneumatic brakes are constructed by installing a tapered shaft sleeve with a wedge onto the shaft, with friction plates that can be exchanged while maintaining the mechanical equipment in its original state. The heat generated by friction is dissipated by a cooling plate installed on a disc with a hub. The friction plate is a double cut split type, which can be exchanged by using a screwdriver to remove the countersunk screw through the hole of the hub disc. Pneumatic brakes have good heat dissipation and can be widely used in industries such as packaging machinery, wire and cable equipment, thin paper, and corrugated paper.

Pneumatic brakes, also known as ventilated brakes, mean that there is a fully inflated air that applies pressure to the socket to achieve braking effect, which is widely used in industry. When it comes to pneumatic brakes, they are also divided into normally closed brakes and normally open brakes. Normally closed brakes keep their sockets open when they are not working, and when they are ventilated during operation, they brake and form a brake.

The products are widely used in lifting, mining, mechanical metallurgy, electricity, railways, water conservancy, ports, chemical engineering, and docks. Our factory has obtained the special equipment type test certificate issued by the National Lifting Machinery Quality Supervision and Inspection Center. It was rated as a contract abiding and credit worthy enterprise in Henan Province and a contract abiding and credit worthy enterprise in Jiaozuo City. Our factory adheres to the principle of quality and customer satisfaction. Think about the user's thoughts, be anxious about the user's anxieties
