Concrete structural features plug-in vibrator
The machine consists of a motor, flexible shaft assemblies, rods three components.
l, the motor housing with aluminum casting, top with switch and handle, the ends equipped with anti-reverse means and coupling head, so that moving light and flexible. ʱ?? 2, anti-reverse device system borne by a push button, when the motor is rotated forward in accordance with the need to push the key due to centrifugal force, its rapid insertion shaft plug head, pushing shaft is rotated, the vibration rod vibration concrete needle vibrator for sale price When the motor coupling due to electrical phase incorrect reverse rotation occurs, the push button that is disengaged and the shaft plug, flexible shaft no longer rotates, so as to achieve the purpose of preventing the reversal protection shaft. ʱ?? 3, the motor with the latest series of three-phase asynchronous motor, it has a small, light weight characteristics, fully enclosed, E-class insulation. It can be used in dusty, soil and water splashes place. 4, high frequency vibrator, is obtained by a set of planetary bodies within the rod, so that when the vibrator at work, flexible shafts and bearings and other transmission parts, are still at a low speed (ie, motor speed). So, despite the vibrator longer work, but the other pieces of flexible shafts and bearings are not very hot. Thus, it has a low speed shaft. High frequency vibrator features.
Second, the structural characteristics
Vibrator by the vibration rod assemblies, flexible shaft hose assemblies and motor parts. Vibrator assembly includes a tip, sleeve, roller, tapered roller, seals, bearings. Tapered roller cone top, tapered roller bearings top and center of the design in regard to the rotation angular velocity uniform, easy to start vibration, overload increase, to avoid sliding and fever. Dual seal device may improve sealing performance vibrator to effectively prevent slipping into the oil. The dual seal device won the national utility model patents. Using a special big gap to make tapered roller bearing swing concrete poker vibrator for sale china freely and increase their ability to resist vibration. Sleeve ends are made of left-handed screw connection, tapered roller shaft ends and joint use of the right-handed screw connection, simple structure, reliable connection.
Third, the method used
1. Connect the three-phase power (in this case not connected rods), observe the motor rotation direction, when viewed in the direction toward the head counterclockwise rotation is forward, or should change the wiring, pay attention to prevent the motor-way operation. 2. Work First positive spin coupling is over the handle, the shaft plug into the motor shaft bore, the coupling head and then inserted into the nose hole and Banxia coupling handle, making it falling into the coupling head arc groove. The new vibrator can lock the first circular groove, until the hose elongation lock the second track circular groove. Open the switch, the vibration of the club head gently knocking, vibrating rod issue, "Om ......" high-frequency sound to use. 3. vibrator vibrator can naturally sink down the concrete, do not force hard insert, but can not use vibrator pry bars, templates, etc. (when using the hose bending radius not less than 25 cm) to avoid damage to shaft hose, affecting life. concrete table vibrator china brand Insertion depth vibrator should generally not exceed the end of the hose fitting. The vibration in real time for each interpolation interval points to 5-7 times the diameter appropriate vibration club. Tap the desired duration depends slump concrete, generally bubbles stop discharging, mix no longer in its surface subsidence and cement mortar layer occurs, said that it has fully tapped, excessive vibration and vibration are less influence structural strength of concrete. 5. after use, should clean the surface of the parts of the vibrator, and then stored in a dry place. Shaft hose should be straight state storage. 6. vibrators need to move, should first unplug the power cord, and motor and rods partially separated, then transferred.
