sluice gate and hosit / work gate and hoist
Work Gate
A complete set of gate normally contains three parts:
(1) gate leaf, the water holding part;
(2) embedded and fastening part, to transfer the weight of the gate and water pressure to the civil foundation;
(3) lifting mechanism.
According to difference applying situation, gates can be shaped into flat gate, radial gate, pipe gate, flap gate, and etc.
1.Flat Gate
Flat gate is one of the most common used types for different kinds of hydraulic related projects. The applying water head varies from 0.5 meter to 200+ meter.
2.Radial Gate
Radial gates perform excellent on the water outlet condition, which lessen the cavitation much.
However, due to its special shape, the radial gate is relative space consuming. With the bearing stress of the center support being large, the difficulty and cost of the civil foundation of the center support will inevitably increase.
A set of radial gate normally contains: radial gate leaf, main girder, auxiliary girder, truss, support arms and support hinge.
3.Other Gates
Pipe jet, Circle outlet, Square outlet
Hoist
Winch hoist, screw hoist and hydraulic hoist is the three most common type in use. According to the mobility, the hoist can be classified into mobile type and fixed type. The mobile hoist is common used for multiple gate project where even and step control is not in necessary need. Mobile hoist is especially common used for stoplogs.
1. Winch Hoist
1). reduce gear, motor, winding drum, steel wire
2).sliding gate, fixed gate, radial gate, concrete gate
3).QPQ, QPK, QPG, QHQ, QPT, QPM
4).Up to 5000kN
2. Screw Hoist
1).sliding gate, fixed wheel gate
2).single stem, double stem
3).LQP, LQL, LQS, LQD, LQZ
4).3~250kN
