FAQ

Q: What is the power compatibility of the ZEd AC/DC Dual-Purpose Electro-Hydraulic Thruster?

A: This thruster is compatible with two power supplies: DC220V and AC220V. It satisfies the power requirements of diverse on-site applications, simplifies system design, and enhances equipment versatility.

Q: What are the advantages of the motor used in the ZEd Thruster?

A: Equipped with high-performance brushless motors, it features an extended service life and low maintenance costs. It eliminates brush wear issues inherent to traditional brushed motors, delivering higher operational reliability.

Q: What is the structural composition of the ZEd Thruster?

A: It comprises an intelligent controller and a high-efficiency Ed series electro-hydraulic actuator. Its compact structure facilitates easy integration and maintenance.

Q: What is the suitable ambient temperature range for the ZEd Thruster's operation? Are there any humidity requirements for the application environment?

A: The recommended ambient temperature range is -20 °C to 45 °C. If the temperature drops below -20 °C, a heater must be installed or HY-10 aviation oil must be used. The maximum allowable relative air humidity is 90%. The thruster is for indoor use only, and the installation environment must comply with the relevant provisions of GB/T 15957.

Q: What preparations are required prior to installing the ZEd Thruster?

A:First, verify that the installation site meets the product's environmental requirements (including temperature, humidity, and indoor installation criteria), and clear all debris from the site to prevent installation interference.Second, inspect the thruster and its auxiliary components (intelligent controller, connecting cables, fasteners, etc.) for integrity and damage, ensuring no defects were incurred during transportation.Finally, prepare appropriate tools (e.g., wrenches, screwdrivers) and ensure that installation personnel are familiar with the operating specifications outlined in the product installation manual to avoid unauthorized operations.

Q: What precautions should be observed when wiring the thruster and controller?

A:Ensure the power supply is disconnected before wiring to prevent electric shock hazards.

Strictly identify and connect AC220V and DC220V terminals in accordance with the product wiring diagram; incorrect wiring may result in motor or controller burnout.

Ensure all wire connections are secure and free from loosening or poor contact, and apply proper insulation treatment (e.g., wrapping with insulating tape) to prevent short circuits.

After wiring is completed, double-check the wiring sequence and terminal connections for accuracy before powering on the system for commissioning.

Q: What key points should be monitored during initial power-on commissioning?

A:First, observe the LED indicator status on the controller. Under normal operating conditions, the corresponding power indicator (AC or DC) should remain steadily lit, with no fault alarms (e.g., flashing red light).Second, manually test the thruster's start-stop, lifting, and telescoping functions. Check for smooth operation, and ensure no jamming or abnormal noise occurs; verify that the thruster's running speed meets the set parameters.Finally, test the thruster's limit protection function (e.g., travel limit switches) to confirm that it automatically stops operation when reaching the limit position, thus preventing equipment damage due to overload.

Q: Does the hydraulic oil in the ZEd Thruster require regular replacement? What is the recommended replacement cycle?

A: Yes, regular hydraulic oil replacement is mandatory. Prolonged use can lead to oil performance degradation caused by contamination, oxidation, and other factors, which may compromise the thruster's normal operation. Replacement must be performed in accordance with the product maintenance manual.

Under normal operating conditions (temperature range: -20 °C to 45 °C; no heavy dust or impurity contamination), the recommended oil replacement cycle is 1–2 years.

For harsh operating environments (e.g., high temperature, heavy dust, high humidity), the cycle should be shortened to 6–12 months.

Q: What industries and equipment are the ZEd AC/DC Dual-Purpose Electro-Hydraulic Thrusters primarily suitable for?

A: With its AC/DC dual-power compatibility, high control accuracy, and superior reliability, this thruster is widely used across multiple industries:

Power Industry: Serves as the operating mechanism for power switchgear (e.g., high-voltage circuit breakers, disconnectors) to realize switch opening and closing actions.

Metallurgical Industry: Suitable for controlling gates and valves of metallurgical equipment (e.g., steelmaking furnaces, rolling mills) to regulate material conveying or fluid flow.

Mining Industry: Used for auxiliary control of mining machinery (e.g., mine hoists, crushers), such as gate opening/closing and equipment positioning.

Water Conservancy Industry: Acts as the drive unit for water conservancy gates and valves, enabling gate lifting and valve opening/closing to control water flow.

Industrial Automation Sector: Functions as an actuator in automated production lines, supporting positioning and motion control for material handling equipment and assembly machinery.

Q: What parameters should be considered when selecting the appropriate ZEd Thruster model?

A: Model selection must be based on actual application requirements, with focus on the following key parameters:

Rated Thrust: Determined by the equipment's required driving force; the thruster's rated thrust must be greater than or equal to the actual working load to prevent overload.

Rated Stroke: Selected based on the displacement distance required for equipment operation; ensure the thruster's maximum stroke meets the equipment's motion range requirements.

Rated Speed: Determine the thruster's operating speed based on the equipment's action time requirements to ensure optimal work efficiency.

Power Type: Confirm the on-site power supply type (AC220V or DC220V) and select the corresponding AC/DC dual-purpose model.

Environmental Parameters: Based on the application environment's temperature, humidity, and dust levels, confirm that the thruster's protection class and environmental adaptability meet requirements (e.g., whether a heater or specialized hydraulic oil is needed for low-temperature conditions).
