Single-phase three-phase 200V/380V ZF-150 0.8KW vibrator

ZF Series External Vibrator Product Overview:

The ZF Series External Vibrator, also known as a concrete vibrator or cement vibrator, is widely used in various construction projects, civil buildings, dams, bridges, and for vibrating concrete in prefabricated components. Based on technical characteristics, it can be divided into two main categories: power frequency and high frequency, for users to choose from.

I. Operation and Usage Methods

1. Installation Method: The usage of the external concrete vibrator generally falls into two scenarios: mobile surface vibration and fixed installation for component vibration. For surface vibration, attach a wooden board (or iron plate) to the bottom of the vibrator and secure it to the base plate for use. For fixed component vibration or installation on other vibrating machinery, the installation method should be determined based on design requirements. When installing the vibrator, ensure the mounting screw holes on the base plate are accurately positioned. Misaligned holes may cause installation difficulties, severe misalignment of screws, and abnormal stress on the casing, affecting its service life. The nuts of the base plate mounting screws must be tightly fastened to prevent loosening, but avoid excessive force to prevent damage to the casing feet. Ensure all four mounting screws are tightened uniformly.

2. Operation: The operation of this machine is very simple. Just connect it to a 415-volt power supply to start operation. During trial operation, avoid prolonged idling on hard, dry ground, as this may cause excessive vibration and damage. When moving the vibrator during operation, ensure the four-core cable of the motor maintains a certain length and flexibility. Avoid over-tensioning to prevent wire breakage. During installation and operation, always pay attention to electrical safety measures, and install safety fuses in the circuit. If multiple vibrators are installed on the same component for simultaneous operation, their performance may differ from that of a single vibrator. In such cases, ensure all vibrators operate at the same frequency to avoid interference. For more complex installation and operation issues, address them appropriately during design.

II. Maintenance and Repair Methods Regular maintenance of this vibrator mainly includes the following points:

1. Keep the external surface of the casing clean. Prevent concrete or other materials from accumulating on the casing to avoid hindering motor heat dissipation.

2. Handle the vibrator gently during transportation, installation, and operation to prevent impact damage. Regularly check the motor feet and casing for integrity. If cracks are found, address and repair them promptly.

3. Periodically inspect the base plate mounting screws, end cover fixing long bolts, and terminal box screws for tightness. If any are loose, tighten them immediately (as the long bolts on both sides of the end cover may elongate after prolonged use). Ensure bolts and nuts maintain good threads. During disassembly and assembly, check for thread damage or poor fit, and replace if necessary.

4. Lubricate the bearings at both ends of the motor based on specific usage conditions, typically every three to six months, using high-quality lubricant. Apply an appropriate amount of lubricant, avoiding excess. It is best to remove the bearings during lubrication, clean them with gasoline, dry them, and then reinstall them. When lubricating the bearings, first unscrew the nuts on the long bolts, remove the end cover, and detach the eccentric block to access the bearing seat cover and bearings. During disassembly and assembly, avoid damaging the mating surfaces of the bearing seat cover and casing. When reinstalling the eccentric block, secure it with anti-loosening wire.

5. If abnormal noise, vibration, or a burning smell is detected during operation, immediately disconnect the power supply and stop operation for inspection.

This vibrator has a simple structure. With regular maintenance and proper operation, faults are generally rare.

Possible faults and repair methods are as follows: If the motor suffers mechanical damage due to over-tensioned wiring or negligence, wire breakage may occur. In case of wire breakage, first check the terminal box. If the break is inside the motor, follow standard motor circuit inspection methods for repair. If necessary, the entire stator may need to be pressed out for work, requiring appropriate tools and fixtures for stator pressing.

After a certain period of operation, the motor bearings may gradually wear out and require replacement. Excessive bearing wear may cause the rotor to rub against the stator, leading to damage. In such cases, replace the bearings immediately. The bearings installed at the factory are of high precision, so ensure replacement bearings are of comparable quality.
