Jiaozuo brake

The BYT1 series explosion-proof thruster is mainly used as a driving device for various external block brakes. Its explosion-proof performance complies with the provisions of GB3836.2-2000 "Electrical Equipment for Explosive Atmospheres and Flameproof Electrical Equipment" d ". The explosion-proof signs are" ExdI "and" Exd Ⅱ BT4 ", which can be used in coal mines and Class IIA and IIB hazardous areas with explosive gases in temperature groups T1-T4. Continuous operation S1 and continuous operation S3, and the temperature of the chicken feather environment reaches+50 ℃.

The rated current in the table refers to the line terminal current during rated operation, but if the power supply is at a non rated value, it will inevitably cause a corresponding change in the rated current. Environmental temperature: -20 ℃~+50 ℃, hydraulic oil: DB-25 (SY1351-77) When it is below -20 ℃, YH-10 hydraulic oil can be used without a heater. When using DB-25 hydraulic equipment, a heater must be installed. The travel time is measured at an ambient temperature of 20 ℃. The electric hydraulic thruster is mainly used for YWZ series operating brake shoe brakes, as a mechanical brake for all similar driving devices such as lifting, transportation, and driving. Structure and Action Introduction: The thruster consists of two parts: the driving motor and the body (centrifugal pump), and the body part is composed of a cover, cylinder, piston, impeller, and rotor. When energized, the electric motor drives the rotor shaft and the impeller on the rotor shaft to rotate, generating pressure inside the piston. Under this pressure, oil is sucked from the upper part of the piston to the lower part, forcing the piston and the push rod and crossbeam fixed on it to rise rapidly. By mechanically compressing the load spring through a lever (if the thruster or brake is equipped with a load spring), mechanical motion is generated. (If matched with the YWZ series hydraulic thruster, release the brake). When the power is cut off, the impeller stops rotating, and the piston rapidly descends under the force of the load spring and its own gravity, forcing oil to flow back into the upper part of the piston. At this time, it still returns to its original position through the lever mechanism. (If matched with the YWZ series brake, hold the brake). BED flameproof electric hydraulic thruster I. Overview Ed series electric hydraulic thruster is a very compact drive control device integrating motor, centrifugal pump and oil cylinder. It is widely used as the drive device of various block brakes and disc brakes, and can also be used for the drive control of various industrial valves, gates, directional swing and rotation (<90 °) devices (mechanisms) and clamping devices. 2、 Design features: The shell is made of cast aluminum alloy, with light weight and beautiful appearance; The motor is of non oil immersed structure, with Class B or F insulation (according to user requirements). Good heat resistance and long service life; The motor junction box cover is equipped with a seal and uses a cable stuffing box for incoming lines, which is firm and reliable. The electrical casing protection level reaches IP55; The surface of the motor shaft and push rod are plated with hard chromium treatment, greatly extending the service life of the sealing element; The oil cylinder shell is equipped with a balance chamber on one side, which can allow the thruster to be installed in any direction from 0 to 180 °, thereby expanding its range of use; All seals and bearings of the Ed series are made of world-renowned products, with reliable sealing and long service life; The Ed series fasteners are made of stainless steel material, which is beautiful and durable. 3、 Selection of installation method for vertical installation: the piston rod connecting block faces upwards; Horizontal installation and any position in the middle: the main parameter label faces upwards; All push rod connection blocks of thrusters can rotate. The Ed50-Ed301 fixed seat can rotate 90 °, while the Ed23-Ed30 fixed seat can also provide 90 ° rotation, but the installation height dimension A is increased by 8mm; Regardless of the installation position, the piston rod cannot withstand any force to avoid affecting the use effect and lifespan. The power supply is a three-phase AC power supply with a rated frequency of 50Hz, a rated voltage of 380V/660V, and a allowable voltage fluctuation of+10% to -25% for 660-1140V. Various electromagnetic, hydraulic, pneumatic, drum brakes, various windproof iron wedges, hydraulic wheel edges, and hydraulic top rail brakes. And we can design, customize, research, and develop various non-standard products according to user requirements. The products are long-term used in lifting, mining, mechanical metallurgy, electricity, railways, water conservancy, ports, chemicals, and docks. Our factory has obtained the special equipment type test qualification issued by the National Lifting Machinery Quality Supervision and Inspection Center. It was rated as a contract abiding and credit worthy enterprise in Henan Province and a contract abiding and credit worthy enterprise in Jiaozuo City
