Jiaozuo brake

Product Overview 1. Purpose

YPZ2 series electric hydraulic arm disc brakes (hereinafter referred to as brakes) are widely used for the deceleration, braking and safety protection of modern large-scale special handling machinery, lifting and transportation machinery, ports and docks, metallurgy and other industries. The installation dimensions of this series of brakes comply with the German DIN5435 standard. 2. Features: This series of brakes features self-lubricating bearings at the main swing hinge points, high transmission efficiency, long service life, and no need for lubrication during use; The asbestos free brake pad is plug-in, making it easy and fast to replace; The automatic compensation device for brake pad wear (imported for one-way bearings) can maintain a constant distance between pads and brake torque during use; Other characteristics. Its structural components have been optimized and designed to be safe and reliable. Various additional devices can be installed according to user needs (please specify when ordering): (1) Manual release device (2) Various limit switches: (Release limit switch, Close limit switch, Friction plate damage limit switch, Manual release limit switch) Through PLC control, fault alarm (interlocking) is achieved to ensure the safety of the entire machine in use. (3) According to user needs, anti-corrosion products can be provided, which can adapt to salt mist environments in coastal areas and acid mist environments in the metallurgical industry. 3. The applicable conditions are generally: (1) Environmental temperature -40 ℃ -+45 ℃

2) There should be no flammable, explosive, or corrosive gases in the surrounding working environment, and the relative humidity of the air should not exceed 90%. (3) The power supply voltage is usually three-phase 380V, 50HZ AC (suitable for 60HZ or other power supply voltages according to user needs, please specify in advance when ordering). (4) The altitude of the location of use should comply with GB755-2000 and German VDE0530 standards When the temperature is below -20 ℃, the working fluid of the thruster should be changed to YH-10 aviation hydraulic oil or a heater is required. Please refer to the Ed thruster user manual for details. 4.

Judgment of hydraulic brake related brake failure phenomena

In order to better prevent the vehicle from holding the brake, a series of preventive measures have been taken, especially through the investigation of holding the brake of the through Freight train, which has accumulated some experience. At the same time, in order to find the authenticity of the problem more intuitively, the following measures have been taken: organize special personnel to visit the stations prone to holding the brake one by one, strengthen the contact with the station, and have a detailed understanding of the situation with the relevant personnel of each station who found the holding brake situation, Enable us to have a perceptual understanding and enhance our understanding of the hazards of holding brakes on driving. Timely contact with the train inspection and provide feedback on fault information to reduce or eliminate the occurrence of such faults. In response to the malfunction of other accessories caused by the vehicle's brake application and the serious impact on normal driving order.

Brake holding brake failure is the application failure of Goods wagon caused by poor brake release and brake shoe cannot be separated from wheel tread due to brake failure, hand brake non release and other reasons. Its main hazard is to scratch the wheel tread, resulting in slag and rolling on the wheel tread.

Of course, disc brakes have their own shortcomings. For example, there are high requirements for the manufacturing of brakes and brake pipelines, resulting in high consumption and cost of friction pads. Moreover, due to the small area of the friction pads and the relatively small working surface of the friction, high braking hydraulic pressure is required, and vehicles with power assistance devices must be equipped to use them. The cost of drum brakes is relatively low and relatively economical.
