Attention 16:14:01

BEd series flameproof electric hydraulic thrusters (hereinafter referred to as "thrusters") are mainly used to operate electric hydraulic drum brakes and pumps, ratchets, valves, etc. They can also operate various forms of lever devices to make various movements, such as reciprocating, swinging, Circular motion motion, etc,

This product complies with the technical requirements of the enterprise standard Q/JZHF01-2009 explosion-proof electric hydraulic thruster. The explosion-proof sign is "Exd I" and is suitable for electric hydraulic drum type coal mine belt conveyors (non mining working faces) and mine lifting equipment

Electric hydraulic thrusters for brakes.

The thruster is an ideal component for achieving semi automation and automation of certain mechanical equipment. The piston rod adopts advanced protection, which can reduce wear and corrosion. The oil chamber of the hydraulic system with double-layer protective seal and double-layer sealing ring greatly improves the service life of the thruster. The thruster has the advantages of stable and noise free operation, low power consumption, long service life, and convenient maintenance.

4. Structure and working principle:

The BEd series electric hydraulic thrusters are mainly composed of explosion-proof motors, intermediate flanges, impellers, complete sets of pistons, etc. Connect the power supply to the thruster, and the motor rotates to drive the impeller to generate pressure oil, pushing the piston and connecting rod upward. Maintain its thrust after reaching the predetermined stroke. When the power supply is disconnected, the motor and impeller stop rotating and no longer generate pressure oil. The piston and connecting rod return to their original position under external force. (See Figure 1)

6. Installation adjustment and usage requirements

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

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

6.1.2 There are explosion-proof signs and explosion-proof certificate numbers. Products used underground should have a "MA" mark

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

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

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

6.1.6 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)

6.2 Installation position

The thruster is generally installed vertically (the motor should be located below), and can also be tilted or horizontally installed. However, it must be noted that when tilted or horizontally installed, the balance chamber should be facing upwards, and it must be ensured that the thruster can swing as a whole, and the piston rod is not allowed to bear radial force. Connect the upper and lower connecting holes of the thruster with the matching mechanism using a pin shaft, and add washers and split pins. The pusher linkage can rotate When the thruster is in operation, there should be a certain distance between the upper connecting rod and the upper edge of the cylinder block, which should generally not be less than 5mm.

6.3 Electrical wiring

When wiring, use the special wrench to remove the three bolts on the junction box cover, open the junction box cover, enter the cable into the junction box through the flameproof junction nozzle, and connect the three-phase power line (phase sequence is not required) and ground wire as required. Then install the junction box cover and tighten the bolts. The junction box should be kept clean and ensure that the sealing gasket is in the correct position and not damaged. The diameter of the motor cable should match the aperture of the rubber sealing ring. The large cross-section of the cable used is 4X4mm2, ensuring that there is no gap between the rubber ring and the motor outlet, otherwise the explosion-proof performance will be lost. When the sealing ring of the introduction device ages and deteriorates, it should be replaced in a timely manner, with a size of ¥ 16X ¥ 35X26 Before powering on, the three-phase balance of the power supply voltage and the range of voltage fluctuations should be checked to ensure compliance with international regulations.

Do not open the cover with electricity!!!

6.4. The internal and external grounding bolts should be reliably grounded.

6.5. When the thruster leaves the factory, the working oil is already installed and can be used directly. Due to the decrease in oil, the technical value of the thruster may change, and even it cannot be started. Therefore, except for normal maintenance, it is not allowed to open the oil filling plug or overflow plug arbitrarily

According to user needs, the following additional functions can be installed:

Before adjusting the time control valve, unscrew the blind plugs marked 'S' and' H ', and then rotate the adjusting screw to adjust the rising time and Fall time steplessly.

Screw rotation (to the right)=increased travel time

Screw out (turning left)=reduced travel time

It should be noted that the large adjustment amount is 20 revolutions, and the stroke time of the pusher equipped with a valve has been adjusted to 5 seconds at the factory. After adjustment, the blind plug should be tightened.

The travel switch pusher can be equipped with a travel switch to indicate the position of the piston, and can be equipped with single or double travel switches.

After the installation of the thruster is completed, it should be powered on and run several times. After checking for any abnormalities, it can be put into use.

7. Use and Maintenance

7. 1 Regularly check whether the thruster works normally. The inspection period can be set as shift inspection, daily inspection, etc. based on work conditions

Check if the wiring is firm to prevent short circuits, open circuits, and burning of the motor caused by vibration.

Check the oil every six months. When the oil deteriorates or gets mixed with debris, the oil should be changed. If the oil is insufficient, the oil should be replenished. Users can fill the oil from the oil filling plug, which should not exceed the position of the overflow plug. It should be noted that during the oil injection process, pull the push rod up and down several times to exhaust air and fill the oil chamber with oil.

7.2 When the thruster is working, pay attention to whether the action is normal, whether there is oil leakage or oil seepage, and whether the oil tank has enough oil. If not, supplement it properly.

7.3. When replacing and installing explosion-proof parts, attention should be paid to protecting the explosion-proof surface. All explosion-proof surfaces must not be damaged or rusted, and parts should be coated with 204-1 rust proof oil on the explosion-proof surface during installation.

7.4. During the operation of the thruster, the allowable temperature of the bearing should not exceed 95 ℃ (thermometer method). The bearing should be inspected every six months and the lubricating grease should be replaced. Before replacement, it must be washed clean with gasoline, and the lubricating grease should be ZFG-2 composite calcium based grease.

7.5. When the thruster is installed on the main engine and needs to be repainted, be careful not to paint the piston rod, otherwise it will damage its sealing.

7.6. When the thruster is placed for more than one and a half years, it should be checked for oil leakage before use.

8. Storage and transportation

1. When storing thrusters, they should be kept dry to prevent moisture and sharp changes in ambient temperature.

2. During transportation, it is necessary to prevent rain and not use a rope to cover the push rod for transportation.

According to the temperature of the surrounding medium, it is recommended to choose hydraulic oil according to the following table:
