HYDROMATIC® AND HYDROTARDER® AUXILIARY BRAKES Standard of the Drilling Industry for 60 Years The Hydromatic® Brake or Hydrotarder® is a hydro-dynamic device that absorbs power by converting mechanical energy into heat in its working fluid which is normally water. Resistance is created exclusively by fluid friction and agitation of the fluid circulated between the vaned pockets of the rotor and stator elements with the conversion of mechanical energy to heat taking place directly within the fluid itself. The amount of mechanical energy that can be absorbed in this manner is dependent upon the quantity and velocity of the fluid in the working chamber. It will be readily seen that with any specific quantity of fluid in the working chamber, the velocity of the fluid will be increased with increased revolving speed of the rotor. In this manner the horsepower capacity of the Hydromatic® Brake or Hydrotarder® increases approximately in proportion to the cube of the speed; if the speed is doubled, the horsepower resistance is increased eight times. The hydraulic horsepower capacity increases at this rate to the maximum operating speed of the brake. It should be noted, however, that other limitations such as shaft diameter and fluid flow capacity may be the limiting factor instead of speed.
Still the Simplest and Easiest to Operate The new and improved Hydromatic® Brakes are as easy and simple to operate as ever. Any Driller can operate them without previous experience or special training. All that needs to be done is to open or close the valve that controls the water level in the brake circulating system.
Now Further Ahead Than Ever Today's Hydromatic® Brakes are the result of years of continuous' research and improvement. Drillers who have tried them say the new, improved Hydromatic® Brakes are definitely better than ever and still the best auxiliary drawworks brake ever offered.
APPLICATIONS The Hydromatic® Brake or Hydrotarder® is a versatile piece of equipment. Originally developed for use on heavy duty rotary drilling rigs, its uses have spread to other areas such as cranes, hoists, ski lifts, on and off highway vehicles, gravity conveyors, dynamometers, deep water anchor handling, and many others. Any equipment which generates a surplus of energy on descent can profit from the smooth, fluid action, "power absorbing" efficiency of the Hydromatic® Brake or Hydrotarder®. Because of the special nature involved in most other areas, such as vehicle applications, dynamometers, etc., no attempt has been made to include detailed information for design in this catalog. It is suggested that for any proposed application of this nature, our Engineering Department be contacted.
Almost Impossible to Fail The new, improved Hydromatic® Brakes are practically 100% failure proof. As long as the water supply to the brake is not interrupted, it is practically impossible for anything to get out of order in the brake or for the brake to fail.
Greater Capacity and Safety The chief improvement in the new Hydromatic® Brakes is their increased capacity. Their greater capacity for handling heavier loads at lower speeds steps up drilling operations and provides safer working conditions than ever before.
Ask Your Drawworks Manufacturer If you are operating a rig without a Hydromatic® Brake, or are considering buying a new rig, ask the manufacturer about installing a Hydromatic® Brake. Manufacturers will be glad to recommend the size best suited to your needs. All of them know and recommend the Hydromatic® Brake and are prepared to install it before your drawworks leaves the factory.
FUNCTION OF CIRCULATING SYSTEM Pressures in excess of those recommended will NOT increase the resistance capacity of a brake, but will cause rapid wear on the sealing elements. Since all of the mechanical energy absorbed in a Hydromatic® Brake appears as heat in the water, it will be apparent that the primary function of a Hydromatic® Brake water circulating system is to supply cool water through the inlet of the brake to displace the heated water and thus prevent the formation of steam within the brake; also to remove the heated water from circulating system or dissipate the heat that is in it. The secondary function of a Hydromatic® Brake water circulating system is to provide controls to permit the driller to vary the brake capacity to meet the rig requirements. The capacity at any speed is adjustable by regulating the quantity of water being circulated between the vaned pockets of the rotor and stators in the working chamber. Depending on the type of installation, infinitely close regulation or regulation in any desired number of steps may be obtained by varying the rate of flow into the brake or varying the level of the water in the circulating system and standpipe, dependent on the type of brake and type of circulating system. Any circulating system used must include a means for dissipating the heat from the circulating system at the rate at which it is generated in the water by the retardation of the brake. Heat dissipation may be accomplished by the use of heat exchangers, or by providing a sufficient supply of fluid to act as a heat sink.
CLEAN FRESH WATER REQUIRED A Hydromatic® Brake must have an adequate circulating system that will provide cool water at all times for the loads that it will be required to handle. It is imperative that the water used in the circulating system be fresh and free of all foreign substance. Experience has proven that brackish or corrosive water, when used in the circulating system, causes corrosion that accelerates cavitation and erosion within a brake.
NO SPECIAL CARE REQUIRED When a Hydromatic® Brake has been properly installed, it requires no special care. It should be inspected at regular periods, such as should be done with the entire rig. Each grease fitting on the brake should be lubricated with a good grade of No. 2 waterproof grease equivalent on each round trip before starting in the hole. It is recommended that same type waterproof grease be used consistently, as some types are not compatible with others.
CIRCULATES OWN WATER The rotor in a Hydromatic® Brake is also designed to serve as an impeller for discharging heated water at the discharge ports. The rate of discharge is approximately the same as the rate at which cool water enters the brake, provided the discharge line from the brake is not restricted. During the running in of a stand of pipe with a Hydromatic® Brake revolving in the direction to create resistance, a sufficient volume of cool water must be available at the brake inlet, at pressures between the minimum and maximum recommended, to displace the water in the brake as it is heated.
WINCH / WINDLASS SYSTEMS WITH PARMAC AUXILIARY BRAKE FOR DEEP WATER ANCHOR HANDLING The Parmac Hydromatic® Brake can be used both to control the lowering of anchors from a work-boat, and to control the anchor chain payout during the positioning of the anchor from the rig. When used in conjunction with large anchor handling winches or windlasses, the power absorbing ability of the Hydromatic® Brakes results in better performance, improved control and smoother operation. At 200 feet per minute, the Parmac Hydromatic® Brakes assist in safely making the anchor descent rate three times faster than other equipment being used today.

Brakes are furnished with special shafts to customer's specifications up to the maximum shaft diameter shown. * Based upon maximum possible fluid flowrate thru the brake. ** Based upon maximum rotor R. P. M. and attainable at a flowrate and horsepower less than maximum. Parmac's new generation of Hydromatic Brakes are more efficient for their size and weight. These include the following models: 121, 122, 201, 202, SSR28, 262, 341, 342, 451 and 481.
These newer brakes have an improved sealing arrangement for better
sealing and
longer
seal life, which also simplifies their
replacement. Some of these new models offer easier controlability, and will fit in the old cradle without modification. When the Hydromatic® Brake was first used on drilling rigs for faster and safer well completion, the rigs were moved by mule teams.
Contractors are now moving rigs by Airplane or Helicopter, and the 341, 342 and 451 are available in Aluminum to meet their low weight requirements. When you need auxiliary braking capacity on your rig or semi,
contact Parmac. the Auxiliary Brake People.
