CHANNEL CA TYPE PENSTOCK

DOC. CA.11/08

TECHNICAL SPECIFICATIONS

Penstock for open channel. Tightness 3 sides ( at bottom and on the two sides). This tightness is reached by profiles of different materials, EPDM is mainly used for water. This serie of channel penstock is fabricated in different types depending on the dimensions.

1.- DESCRIPTION OF THE COMPONENTS

Metallic penstocks composed by the following elements: a) Board b) Guides c) Sealing system d) Bridge of mechanism e) Lifting mechanism a) Board The board is composed by a plate electrowelded to a solid frame of laminated profiles. This unit will hold the maximum pressure of the water indicated by design and will transmit this pressure to the guides inserted in the civil work. It is fabricated in several materials and shapes depending on the application. b) Guides The guides are made, as the board, of laminated profiles in several materials. They transmit the effort of the board and at the mean time they operate as sealing against the joint of the board. These guides constitute an easy mounting unit and they assure the perfect working of the penstock. c) Sealing system The sealing system type depends each time on the special penstock. It is made of rubber profile, normally EPDM.The tightness is reached by profiles screwed to the board with stainless steel sheet billet and stainless steel screws. These indicated profiles slide along the flat surface. This surface has an angle fixed by a welding to the guide of the penstock to reduce the friction and avoid the possible defects of the wall. The slides may be made of nylon depending on the size and type of penstock. d) Bridge of mechanism The bridge of mechanism is composed by a metallic structure that supports the actuator mechanism in charge of the lifting of the penstock board. It is made of laminated profiles, stiffener sockets, supporting plates for the mechanism, gussets and other accessories. It is assembled at the upper side of the guides by some gussets and screws so it becomes removable. C.M.O.
