The JZ series energy-saving electromagnetic drum brake external leakage test (mandatory) is included in all the above tests. At the end of the above test, the oil film appearing on the piston rod should not be sufficient to form oil droplets or oil rings. Brake hydraulic cylinders that have not undergone sampling tests should move back and forth more than 20 times throughout their full stroke at nominal pressure (or rated pressure) to check for external leakage. It is required that the oil film appearing on the piston rod should not be sufficient to form oil droplets or oil rings. There should be no external leakage in the exhaust device, buffer device, stroke adjustment device, input device (including deceleration device and driving device), detection and monitoring of the brake hydraulic cylinder
The JZ series energy-saving electromagnetic drum brake is widely used for deceleration and parking braking of various mechanisms in AC driven lifting and transportation, port loading and unloading, metallurgical equipment, mining machinery, and engineering machinery
Meets the standard
The connection dimensions and braking torque parameters of the JZ series electromagnetic drum brake comply with the JB/ZQ4388-86 standard, and the technical requirements comply with the JB/7685-2006 standard;
Main features
1. Good performance
2. The main hinge points are equipped with self-lubricating bearings, which have good transmission efficiency, long service life, and do not require lubrication during use3. The brake pad is a card mounted integral formed structure, which is easy and fast to replace. There are different materials of brake pads available for users to choose from, such as semi metal (asbestos free) hard and semi hard, soft (including asbestos and asbestos free)
Usage conditions
1. Environmental temperature: -25 ℃~40 ℃
2. There must be no flammable, explosive, or corrosive gases in the surrounding working environment3. The relative humidity of the air shall not exceed 90%4. AC 380V/50HZ5. The altitude of the place of use shall not exceed 2000M
