Jiaozuo brake

The voltage of electric hydraulic block brakes is generally 380V in China, with explosion-proof types ranging from 380-660-1140V

Brake operating conditions

The relative humidity of the surrounding air shall not exceed 85% (20 ± 5 ℃)

There is no gas or dust in the surrounding medium that is sufficient to corrode metals and damage insulation.

The brake is equipped with Class B insulation around it, with voltage fluctuations not exceeding+5% and -15% of the rated voltage. Its working mode is in accordance with the continuous working system installation control requirements. The specific process and requirements for installing a frequency converter on the brake.

The basic requirements for selecting a matching frequency converter for motors with brakes are that the frequency converter for motors with brakes must have an internal regenerative braking signal processing unit or an additional regenerative braking signal processing unit as an optional component.

At the same time, in order to maintain the positioning, emergency stop, and stopping of the motor, a motor with a mechanical brake should generally be used.

The connection requirements of the variable frequency speed control system for the brake power supply:

The brake power supply must be connected to the input end of the frequency converter, as the output voltage of the frequency converter is low at low speeds, which will weaken the attraction of the electromagnet and release the brake, which is not allowed.

Therefore, the voltage of the brake cannot be the same as that of the electric motor.

During installation, ensure the accuracy of the fit between the transmission shaft and the brake.

Before installation, the brake must be cleaned thoroughly, and there must be no oil or dust on the friction surface and inside the brake. A series of specialized devices that can forcibly reduce the driving speed of a car. The braking system mainly consists of four parts: energy supply device, control device, transmission device, and brake. The main function of the braking system is to slow down or even stop a moving car, maintain a stable speed when driving downhill, and keep a stopped car stationary. The braking system is essential for every type of vehicle, and without it, the scene would be unimaginable. In the braking system, brakes are also very important. Generally speaking, the role of front wheel braking is greater, surpassing the contribution of rear wheel braking. The front brakes are generally divided into two types: drum and disc.

In general passenger cars, the braking devices of the front and rear wheels are often different. If all four wheels are disc brakes, the front wheels are mostly ventilated disc brakes, and the rear wheels are mostly ordinary disc brakes. If the disc brake is mixed with the drum brake, the front wheel adopts Disc brake, and the rear wheel adopts drum brake.

Use and Maintenance

The working condition of the brake shall be checked regularly, and the following items shall be emphasized during the inspection: 1. Whether the brake components can move normally and whether the adjusting nuts are fastened. 2. Whether the components of the thruster are normal and whether the hydraulic oil is sufficient. Is there any oil leakage or seepage. Check if the insulation of the incoming wires is good. 3. The size H1 should not be less than the small dimensions listed in Table 1. If it exceeds the requirements, it must be adjusted immediately, otherwise the braking effect will be lost. 4. Check whether the brake shoe rests on the brake wheel normally, whether the friction surface is in good condition, and whether there is greasy dirt. When the thickness of the brake pad reaches the values in Table 2, the brake pad should be replaced. 5. The temperature of the brake wheel should not exceed 200 ℃. 6. If cracks are found on the lever and spring, they should be replaced.

The YWZ series electric hydraulic block brake adopts the MYT1 series thruster as the driving device of the brake. The installation dimensions comply with JB/ZQ4388-86 standard. Mainly used for mechanical braking of mechanical driving devices in lifting transportation, metallurgy, mining, ports, construction, and other fields.
