DOC.GR.11/08 Damper guillotine type GR manufactured by CMO is especially useful as an element of isolation to allow inspections, maintenance and repairs on the pipes. The basic mechanical elements that make up the guillotine type of damper GR, is a rack or foreign body that contains a piece that moves inside lengthwise, a sealing peripherical to prevent leakage of gas in all phases of the movement of the knife of gate, necessary supports and an actuator ADVANTAGES OF THIS TYPE OF DAMPERS - Good insulation. - Low pressure drop when the damper is in the open position. - Somewhat space needed along the conduit. - Good wear resistance due to fly ash from the oven.

BODY Normally the body of this kind of gates is completely welded constructed and built a base plate with different thicknesses and structural shapes reinforcements to prevent possible deformations. The material used is usually carbon steel S275JR but depending on the temperature of work there are other special materials to choose from, such as steel HII, 16MO3 steel, stainless steels (AISI304, AISI316, AISI310) and so on. Body extends upward beyond the duct (approximately twice) to accommodate the road when the damper is in the open position as the opening is made through a longitudinal...

DOC.GR.11/08 SEALING The closure of the damper guillotine type GR is provided through the contact between the blade and sealing strips that are welded peripherally in the interior of the body of the gate. The closure strips are of the same material as the frame is welded to give the best possible contact with the road, to ensure the tightness is estimated to be 98.5%. Besides them there is a wedge (on the gate) and wedge (the body) whose function is to adjust and increase even more contact between the decks and closing the road when it comes to the closed position. SYSTEM OF ACTUATION The...

During the handling of equipment, during transportation (loading and unloading) is due to put special emphasis on the following points: Check that the crane is able to support the weight of the equipment to raise. ? Make sure the computers are properly covered. ? Do not elevate equipments with the crane holding in the area of operation Equipments are supplied with lifting lugs for that purpose, as the team's own weight could damage the drive. Do not elevate equipments by holding the area of step flow This can cause damage to the closures and areas of tightness. ? It is recommended to raise...

During the handling of equipment during the assembly should put special emphasis on the following points: ? Do not elevate equipments with the crane holding in the area of operation Equipments are supplied with lifting lugs for that purpose, as the equipment's own weight could damage the drive. ? Do not elevate equipments by holding the area of step flow This can cause damage to the closures and areas of tightness. INFORMATION OF SECURITY Check that the crane is tared to support the weight of the equipment to raise. Make sure the computers are properly covered. Both during the assembly...

DOC.GR.11/08 C.M.O. - Once the equipment placed at the site was initially recommended by a welding brackets and go to controlling the tensions that are created by the process of welding. After conducting the continuous welding of the union between the duct and the gate. The equipment needed to carry out the welds (type of welding electrodes etc.) and the preparation of edges will be specified in the selected procedure weld. - It is vital that during the assembly process there is no deformation on computers, as these can lead to an incorrect operation. - With respect to scaffolding, ladders...

In implementing the maintenance of equipment, and to prevent personal injury or property should be taken into account the following points: - The staff in charge of the operation and maintenance of equipment must be qualified and trained in operations with this type of equipment. - Use appropriate means of personal protection (gloves, safety boots, goggles, helmet, reflective vest ...). Important aspects of security for workers when it comes to performing maintenance: - Areas where there is a movement, both internally and externally for driving, are areas of risk. Especially in equipment...

DOC.GR.11/08 CHANGE OF JOINTS IN ACTUATORS Acted on computers using pneumatic or hydraulic actuators can present different problems to be working for long periods of time. Most common problems are usually due to wear of gaskets of the cylinders, causing the two chambers of the cylinder to communicate or leakage to the outside. To avoid such problems is the installation of filters before the entrance to the drive to clean and lubricate the fluid pressure, either air or oil. This will lengthen the life of the drives. In case of observance of the above problems is necessary to change the...

DOC.GR.11/08 C.M.O. The bearings are fitted with grease points are easily accessible from the outside. Depending on the maneuvers of the gate the time period in which we must perform maintenance is different. As a general idea if you consider that the gate is operated by an average of less than 2 per day maneuvers will be carried out by the oil every 6 months. If, by contrast, the number of maneuvers is 2 to 4 per day, I realize the oil every 3 months. For larger numbers to perform the maneuver was recommended greasing every 2 months. There are two types of fats has used as a function of...
