HF-ET-804 Portable Dynamic Balancer

Product Overview

This portable on‑site dynamic balance tester is packed in a rugged aluminum alloy carrying case. It performs dynamic balance correction directly on rotating machinery without disassembly. It supports single‑plane / double‑plane balance measurement, real‑time vibration inspection and vibration spectrum analysis. It displays rotational speed, vibration amplitude and phase digitally, and calculates the weight & phase for adding or removing counterweights for rotor balancing.

Main Features

1. Chinese menu interface, human‑machine interactive operation, simple and fast workflow.
2. Large‑size LCD screen for clear data display; analog meter for auxiliary status indication.
3. Supports single‑side (single‑plane) and double‑side (double‑plane) field balancing for rotating rotors.
4. Measures rotating speed, vibration amplitude and phase; outputs exact weight and phase for balance adjustment.
5. Integrated vibration analysis function for machinery fault diagnosis.
6. Compact aluminum alloy enclosure, portable for field maintenance work.

FAQ — Portable Dynamic Balancer

Q1: What is a Portable Dynamic Balancer used for?

A: This portable dynamic balancer performs on‑site rotor dynamic balancing without disassembling rotating equipment. It applies to motors, fans, turbines, centrifugal pumps and other rotating machinery. It supports both single‑plane and double‑plane balancing, and can also measure vibration amplitude, velocity, phase and rotational speed for mechanical fault diagnosis.

Q2: What are the other common names for this instrument?

A: Portable Rotor Dynamic Balancing Tester, Field Dynamic Balance Analyzer, Vibration & Balancing Meter, On‑site Dynamic Balancing Device.

Q3: What is the main advantage of on‑site balancing?

A: No need to remove rotors for off‑site balancing lab service. Balancing can be completed directly on the machine, greatly cutting downtime and maintenance costs.

Q4: What rotational‑speed range does the balancer support?

A: Typical working speed range: 300 ~ 30000 rpm, covers most common industrial rotating equipment.

Q5: What vibration measurement capabilities does it have?

A: It measures vibration amplitude(peak‑to‑peak), vibration velocity(RMS) and phase angle (0‑360°, typical phase accuracy ±1°).

Q6: What is the balancing effect?

A: Unbalance reduction rate ≥85% after proper calibration and weight correction.

Q7: What is the power supply?

A: AC 220V mains power supply. Housed in shock‑proof aluminum alloy portable case for field transport.

Q8: Does it support single‑plane and double‑plane balancing?

A: Yes. Two modes are selectable:

• Single‑plane: For thin‑disk rotors (fans, small impellers).
• Double‑plane: For long‑shaft rotors (large motors, turbine rotors).

Q9: Can the instrument calculate correction weight and angle automatically?

A: Yes. After collecting original vibration data and trial‑weight data, the unit automatically outputs the required correction weight value and phase angle for adding or removing mass.

Q10: Can it be used for vibration analysis besides balancing?

A: Yes. It can work as a vibration analyzer to check vibration status and assist preliminary mechanical fault diagnosis.

Q11: What accessories come with the unit?

A: Main unit, vibration sensor, speed‑measuring sensor, connecting cables, operation manual, aluminum alloy carrying case.
