The BED series explosion-proof electric hydraulic thrusters are mainly used as driving devices for electric hydraulic drum brakes, and can also achieve rapid movements such as reciprocating, circular, and swinging through levers. They are suitable for industries such as lifting, transportation, metallurgy, mining, ports, and construction; Its explosion-proof performance complies with the provisions of GB3836.2-2000 "Explosion proof Electrical Equipment and Explosion proof Electrical Equipment for Explosive Atmospheres" d ". The explosion-proof signs are" dI "and" DIICT4 ", which are respectively used in coal mines and IIA, IIB, IIC (Class I, Class II, Class B, Class II, Class C, Class II) temperature groups T1-T4 combustible gases or explosive mixtures formed by steam and air

Installation adjustment and usage requirements

Before installation, the following inspections must be carried out. If they do not meet the requirements, they are not allowed to be used.

The thrust on the thruster nameplate should match the required thrust.

Equipped with explosion-proof signs and explosion-proof certificate numbers. Products used underground should have a "MA" mark

The explosion-proof level and group of the thruster should meet the requirements for explosive mixture locations.

All fastening bolts should be tightened, and all components of the explosion-proof enclosure should be properly connected.

All explosion-proof parts should be free from cracks and defects that affect explosion-proof performance.

The insulation resistance between the stator winding and the casing shall not be less than 0.38M (rated voltage 380V), 0.66M (rated voltage 660V), and 1.4M (rated voltage 1140V)

The selection of brake type mainly depends on the product standard requirements and actual needs of the host or mechanism to determine the type of brake. As stipulated in the standard, the lifting mechanism and the luffing mechanism must be equipped with a normally closed brake, and the walking or rotating mechanism can use a normally closed brake. Consider the location of use, and if there is sufficient space for brake installation, block type, belt type, or arm type disc brakes can be selected; When the space is limited, the internal shoe type or clamp type disc brake can be selected. Considering the usage environment of the supporting host, electromagnetic or pneumatic brakes should be selected for occasions with strict requirements for oil leakage. For metallurgical sites with high environmental temperatures, electric hydraulic brakes or metallurgical electromagnetic brakes with higher insulation levels can be selected. When using electric hydraulic brakes in low or high ambient temperatures and in outdoor areas, attention should be paid to replacing the corresponding brand of hydraulic oil. In environments containing iron filings and severe dust, the use of electromagnetic brakes should be avoided to prevent dust from entering the gap of the electromagnet and affecting its suction. For special or important occasions, additional functions of brakes should be added as needed. In low temperature environments, electric hydraulic thrusters can be used for heaters. When there are strict requirements for the transition between starting and braking processes, install a travel switch to understand the opening and closing status of the brake. For environments where maintenance and adjustment are difficult to implement, brake gap equalization devices and automatic compensation devices for friction plate wear can be installed. Adding a manual brake release device can manually open the brake in special circumstances.
