Jiaozuo brake

The electric motor of the electric hydraulic thruster is connected to the middle of the body with a cover. There is a piston with two push rods inside the body, and a blade wheel is connected to the rotating shaft. The rotating shaft is supported by a support plate equipped with rolling bearings, which is fastened to the piston and is sturdy with screws. The upper end of the body is connected to the crossbeam through the push rod, and the crossbeam is equipped with a connecting rod for connecting the pin shaft and the matching hydraulic push rod brake. The pin holes under the body are also used for connection. When energized, the main shaft of the electric motor drives the slide to rotate the shaft and the impeller on the shaft at high speed. Under the action of centrifugal force, the oil in the oil pipeline generates a pressure difference, which causes the oil to be sucked from the upper part of the piston to the lower part, forming high pressure at the lower part of the piston, forcing the piston and the push rod and crossbeam fixed on it to rise rapidly. When the piston rises to the top position, the lower part of the piston maintains a constant pressure. At the same time, mechanical motion is generated by compressing the load spring through a lever mechanism (if the thruster or brake has a load spring). (If matched with the YWZ series hydraulic push rod brake, release the brake) When the power is cut off, the impeller stops rotating, and the piston rapidly drops 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).

4、 Instructions for use:

1. Installation test: First, check whether the thrust on the nameplate of the electric hydraulic thruster product matches the required force: remove oil stains on the motor and body surface, and check whether the push rod lifting is smooth. Unscrew the oil filling plug 5 (Figure 3) and oil level plug 3, and inject suitable and pure hydraulic oil until the screw hole 3 is reached. Then tighten plug 3 and plug 5. According to different ambient medium temperatures, it is recommended to follow Table 6 for hydraulic oil. The temperature of the surrounding medium is+45 ℃~+21 ℃+20 ℃~+0 ℃+0 ℃~-15 ℃~-15 ℃~-30 ℃ - below 30 ℃. 20 # mechanical oil GB443-64, 10 # transformer oil (freezing point -10 ℃) SYB1351-62, 25 # transformer oil (freezing point -25 ℃) SYB1351-62, instrument oil (freezing point -60 ℃), GB487-65, a mixture of alcohol and glycerol. It is recommended to use oil to connect the lower part of the hydraulic thruster with a pin, and connect the connecting rod of the crossbeam with a lever device with a pin. After testing whether the external power supply matches the motor nameplate, correctly connect the motor terminal to the external power supply. Connect the power supply and check whether the impeller operates flexibly and whether the push rod lifts smoothly. 2. Use and maintenance: check whether the electric hydraulic thruster works normally and whether there is oil leakage or oil seepage. A constant amount of oil should be maintained. But note that the oil level cannot be higher than the oil level plug. If it is higher than the oil level plug, there may be oil leakage at the push rod, motor, and cylinder head. Check the oil at least every six months. When the oil deteriorates or mixes with impurities, the oil should be changed when the viscosity increases. If the oil selection is not appropriate, a separate selection should be made. Check if the motor wiring is in good condition and if the protective device is appropriate and reliable.

Oil for thrusters

The thruster has been equipped with hydraulic oil according to regulations when leaving the factory. If the thruster has been stored for a long time (more than 6 months), screw out the plug before use to check whether the oil level is normal. If the oil level does not reach the specified level, hydraulic oil should be added to the specified level (see Figure 1), otherwise the thruster cannot work properly. The hydraulic oil grade can be found in Table 2 (Mobil, Shell, and other hydraulic oils equivalent to the grade in the table can also be used), and the hydraulic oil filled must not contain impurities or dirt (it should be filtered). When adding hydraulic oil, the push rod should be slowly pulled up and down several times to remove air from the hydraulic cylinder and ensure sufficient oil is added.
