Electro-Hydraulic Thrusters

Electro-Hydraulic Thrusters

Electro-hydraulic thruster is a kind of drive control system, which is very compact in structure, and integrates electrical motor, centrifugal pump and oil cylinder. It is extensively used as drive mechanism of various drum and disc brakes, and as drive control of various industrial valves, penstock, directional pendulum and steering(<90°) mechanism and clamping devices.
Product description
系列:
Ed Series

OPERATING CONDITION

Ambient temperature
-20℃~+50℃

Relative humidity

≤90%;anti-corrosive thrusters should be 
selected for damp and hot areas or corrosive environment

Operating duty

Intermittent(S3-60%) and continuous(S1)

MAIN FEATURE

01

Electrical motor is of non-under-oil structure, B grade or F grade insulation (according to customer's requirements), durable and good heat resistance. 

02

Cover of junction box is tightly sealed. Cable stuffing box is adopted for inlet wire, which is firm and reliable. Protection class of electric casing reaches IP65. 

03

Balancing air chamber  is set up at one side of oil cylinder housing, which can make the thruster to be installed at any direction within range of 0~180°and enlarge the using range.

04

The casing is made by casting aluminum alloy, light and good-look.

05

The surface of motor shaft and pusher shall be specially treated specially to make seals be much more durable.

06

All seals and bearing are all world famous products. The sealing is reliable and durable.

07

Fasteners are made of stainless steel, good-look and durable.

STANDARDS COMPLIANT

Foundations can be installed by revolving 90°(pelease note it when customers ordered),head of push rod can be turned 360°freely,all thrusters can be vertically and (≥15°) obliquely or horizontally installed,the balancing air chamber is shown as riht figure:

ADDITIONAL DEVICES

Upper limit switch, which can indicate whether brake is open, or whether the thruster is at the right position.

Lower limit switch, which can indicate whether the brake is properly closed, whether the thruster return to right position. Upper and lower limit switches can be set together.

Additionally install build-in spring (only for short stroke thruster). Spring force can be decided by customers, but within the force limit of built-in spring (refer to parameter tables).

Heater: Customers can require heaters in the place where ambient temperature is below-25℃. Parameters of heaters are attached.(refer to Tab.1)

Ascending time-delay valve,descending time-delay valve or ascending/descending time-delay valve can steplessly prolong the rising and falling time,delay range is from 5s to 30s,specific delay time can be set as customers’ requirements.

Upper limit switch, which can indicate whether brake is open, or whether the thruster is at the right position.

Lower limit switch, which can indicate whether the brake is properly closed, whether the thruster return to right position. Upper and lower limit switches can be set together.

Additionally install build-in spring (only for short stroke thruster). Spring force can be decided by customers, but within the force limit of built-in spring (refer to parameter tables).
