QWZ4000 Pneumatic Vibrator for Metro Segment Tunnel Trolley

This machine is suitable for vibration compaction of concrete precast components in water conservancy and power construction sites, high-rise buildings, mines, underground construction, as well as highway and railway bridge girders, T-beams, and large precast component factories, thereby shortening the concrete curing time and improving strength. It can also be installed on various vibration equipment as a vibration source, such as loading, unloading, transportation, filtering, and screening of bulk materials.
Product Principle
The machine is driven by compressed air, which outputs torque and drives the mechanism to perform planetary rotational motion, generating mechanical vibration.
Features and Differences
1. Utilizes aerospace processing technology and special materials, with a quality level comparable to foreign products.
2. Features a cast iron casing, enabling amplitude performance that exceeds that of aluminum-cased products. The amplitude frequency is adjustable, and the excitation force is 1.5 times that of other similar products. The overall weight of the product is 1.3 times that of other similar products.
Product Features
1. Compact size, lightweight, and convenient for construction.
2. Adjustable frequency and excitation force; the frequency can be adjusted according to the specific compaction needs of concrete. By controlling the opening and closing degree of the intake valve, i.e., regulating the gas flow, the frequency can be adjusted, and the excitation force can be correspondingly increased or decreased.
3. Operation
No ignition risk in gas environments, and unaffected by harsh conditions such as high temperatures.
Equipped with overload protection, preventing malfunctions due to overload. In case of overload, it only reduces speed or stops. Once the overload is resolved, normal operation resumes immediately.
4. High adaptability
High starting torque, enabling direct load start.
Strong water resistance and impervious to moisture, a particularly outstanding advantage compared to electric vibrators. However, excessive water ingress is still harmful.
Can be used in remote or power-deficient areas when paired with a diesel generator.
Due to the absence of bearings, daily maintenance is reduced under high-speed working conditions, avoiding issues related to bearing wear.
