The JZ - 200 is a typical model of the JZ series energy - saving electromagnetic drum brakes. It adheres to industry standards such as JB/ZQ 4388 - 86 and JB/T 7685 - 2006, with a braking wheel diameter of 200mm and a braking torque of 160N·m. It is widely used in industrial fields relying on its energy - saving and reliable performance. The following is a detailed account of its advantages and usage:
Core Advantages
Stable and Quiet Braking PerformanceIt adopts a normally - closed design. When the power is cut off, the spring drives the braking action; when the power is turned on, the electromagnet realizes release. The brake is equipped with riveted non - asbestos brake shoes, which not only meet environmental protection requirements but also ensure a stable braking effect. During the braking process, it runs smoothly without harsh noise, creating a comfortable working environment for the operation site. In addition, its action frequency can reach 1200 times per hour, enabling rapid response to braking demands and effectively improving the working efficiency of the supporting equipment.
Energy Conservation and Long Service LifeThe brake is characterized by energy - saving performance, which meets the current high requirements for industrial energy efficiency. Its main swing hinge points are equipped with self - lubricating bearings. These bearings not only enhance transmission efficiency but also eliminate the need for additional lubrication during use, reducing daily maintenance workload. The matching DT - 200 electromagnet has stable performance. Combined with the reasonable structural design of the brake itself, the overall service life of the equipment is prolonged, and the frequency of parts replacement is reduced.
Simple Structure and Convenient MaintenanceThe overall structure of the JZ - 200 is compact, with a total weight of only 26kg. Its standardized installation interface allows for direct connection to the equipment shaft, requiring no complex adjustments during installation. The brake shoes can be customized into a clamped integral structure according to user needs. When the brake shoes are worn, they can be replaced quickly without disassembling the entire brake, which greatly shortens the maintenance time and reduces maintenance costs.
High Safety and Strong AdaptabilityThe normally - closed design serves as a fail - safe guarantee. When the equipment has a power failure or the electromagnet malfunctions, the brake can automatically perform the braking action, preventing safety accidents such as equipment runaway. It can also be customized into explosion - proof and non - standard models according to user requirements to adapt to different working conditions. Meanwhile, it is applicable to an altitude of less than 2000 meters and an ambient temperature range of - 20°C to 40°C, and can operate stably in ordinary industrial environments with a relative humidity of no more than 90%.
Application Scenarios and Usage Notes
Typical Application ScenariosThis brake is mainly used for deceleration and parking braking of various mechanisms. It is widely applied in lifting machinery such as small and medium - sized overhead cranes and electric hoists in workshops and warehouses. Moreover, it is also suitable for transportation, metallurgy, ports, docks, and construction machinery fields. For example, it can be installed on belt conveyors in metallurgical plants and transmission mechanisms of small port loading and unloading equipment to ensure the safe and stable operation of the equipment.
Key Usage Notes
Strictly Comply with Power Supply Requirements: The brake uses an AC 380V, 50Hz power supply. During use, the stability of the power supply should be guaranteed, and voltage fluctuations should be avoided as much as possible, as excessive fluctuations will affect the suction of the electromagnet and further reduce the braking effect.
Control the Working Environment: It should be avoided to use the brake in environments with flammable, explosive gases and conductive dust, as these substances are likely to corrode the brake parts and damage the insulation performance of the electromagnet. If it is used outdoors, an anti - corrosion modified model should be selected to resist the erosion of rain and snow.
Regular Daily Inspection: Regularly check the wear degree of the brake shoes. Once the wear is excessive, replace them in a timely manner. At the same time, inspect the tightness of the mounting bolts and the surface of the electromagnet. Clean the dust on the electromagnet surface regularly to prevent overheating due to poor heat dissipation. For long - term idle equipment, before restarting, manually check the flexibility of the swing hinge and the elasticity of the brake spring to ensure that there is no jamming.
