marineusedgood Provide various models and specifications of manual windlass, electric windlass and hydraulic windlass. Certificate of classification society can be provided.
The windlass is mainly used for the anchoring operation on the ship, in order to achieve the mooring maneuver of the fixed position, control the speed of the ship and the rotation of the bow. It is mainly composed of prime mover, reduction gear, clutch, winch, brake and control device.
According to the driving form, it can be divided into: manual, electric and hydraulic.
In the hydraulic driving mode, a hydraulic oil pump is driven by an electric motor to establish power oil pressure, and then a hydraulic motor is used to drive a windlass and a winch. It has the characteristics of stable speed regulation, stepless speed regulation, and large starting torque. So it is widely used in medium and large ships.
There are two types of windlass: horizontal and vertical. Merchant ships generally use horizontal windlass. The vertical windlass is also called anchor winch. Its power section is located below the deck to save deck area. In recent years, due to the large size of the windlass, the bow deck is difficult to accommodate, and it is not easy to operate, so vertical windlass has also been used.
Marine hydraulic windlass is also called electric hydraulic windlass. It uses an electric motor to drive the oil pump, uses a high-pressure oil drive motor, and then drives the transmission gear through a reducer (or without a reducer) to make the windlass run. Its structure is compact and bulky. Smaller. Now there is an automatic hydraulic windlass, which is provided with an anchor chain length sensor. When the anchor chain to be thrown is thrown out when the anchor is dropped, the windlass will automatically stop; when the anchor is approaching the anchor chain drum, , Can automatically decelerate; when the anchor enters the anchor chain cylinder and receives it, it will automatically stop.
Composition of marine windlass
Marine windlass mainly consists of base, bracket, anchor sprocket, brake, sprocket, gearbox, electronic control system, hydraulic pump station and so on.
Main technical parameters of marine windlass
1. Anchor chain diameter: 19—105mm
2. Work load: 15-523kN
3. Pull winch: 15-250kN
4. Motor power: 7.5-250KW
Product attributes of marine windlass
The ship's windlass adopts electric-hydraulic power supply, and is symmetrically arranged. 1 anchor sprocket, 1 strand drum, 1 auxiliary drum per set. Driven by hydraulic motor through open gear. The power pump station is composed of 2 oil pump units and 1 oil tank, and the proportional valve is operated and controlled beside the unit.
Classification of marine windlass
1. According to the arrangement, it is divided into single-sided hydraulic windlass and double-sided hydraulic windlass.
2. It is divided into hydraulic windlass and hydraulic combined windlass according to function.
