The YWZ4 series electric hydraulic drum brake (equipped with Ed series thrusters) is widely used for deceleration or parking braking of mechanical drive devices in lifting, metallurgy, mining, ports, docks, construction machinery, and other fields
Compliance with standards:
The installation dimensions of the YWZ4 series electric hydraulic drum brake (equipped with Ed series thrusters) comply with the JB/T6406.2-1992 standard.
Main features: The main swing hinge points are equipped with self-lubricating bearings, which have good transmission efficiency and do not require lubrication during useThe main performance is stable, with smooth braking and high frequency of actionThe asbestos free brake pads and brake pads adopt a card insertion type, which is convenient and fast to replace
Usage conditions:
Environmental temperature -20 ℃ to+50 ℃
Relative humidity: should not exceed 90%There must be no flammable, explosive, or corrosive gases in the surrounding working environmentThe altitude of the usage site complies with GB755-2000Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion (based on actual reports) products
When using the YWZ4 series electric hydraulic drum brake (equipped with the Ed series thruster), daily maintenance and upkeep should be carried out:
1. Keep the caliper hydraulic brake assembly, especially the surface of the brake disc and brake lining, clean to ensure that the entire brake operates freely, is flexible, excellent, and clean.
2. Regularly observe the stock of brake fluid in the oil pool. When the liquid level is below the marking line, clean brake fluid of the original brand should be added in a timely manner, so that its height is millimeters higher than the marking line. Adhere to the contract and allow the addition of other brands of brake fluid. After adding, the air nozzle should be opened for exhaust before tightening for use3. Regularly check the thickness of the brake disc (usually above the mileage). When the thickness of the worn brake disc is less than the specified value, the brake disc must be replaced4. During use, the surface of the brake lining should not be contaminated with grease or brake fluid, and the thickness of the lining should be checked regularly. If the thickness is less than the specified value, the dynamic lining should be replacedWhen there is oil leakage at the piston of the master pump and the slave pump, the sealing ring must be replaced. Special attention should be paid to the fact that new sealing rings must be soaked in brake fluid for at least an hour before being replaced. They cannot be assembled and used immediately after being taken out. When cleaning the oil cylinder or piston, it is necessary to use a spray solution, and gasoline or other mineral oil liquids are not allowed
