HYDROMATIC AND HYDROTARDERAUXILIARY BRAKES
Standard of the Drilling Industry for 60 YearsThe Hydromatic Brake or Hydrotarder is a hydro-dynamic device
that absorbs power by converting mechanical energy into heat in itsworking fluid which is normally water. Resistance is created exclusivelyby fluid friction and agitation of the fluid circulated between the vanedpockets of the rotor and stator elements with the conversion ofmechanical energy to heat taking place directly within the fluid itself. Theamount of mechanical energy that can be absorbed in this manner isdependent upon the quantity and velocity of the fluid in the workingchamber.
It will be readily seen that with any specific quantity of fluid in theworking chamber, the velocity of the fluid will be increased withincreased revolving speed of the rotor. In this manner the horsepowercapacity of the Hydromatic Brake or Hydrotarder increasesapproximately in proportion to the cube of the speed; if the speed isdoubled, the horsepower resistance is increased eight times. Thehydraulic horsepower capacity increases at this rate to the maximumoperating speed of the brake. It should be noted, however, that otherlimitations such as shaft diameter and fluid flow capacity may be thelimiting factor instead of speed.Still the Simplest and Easiest to OperateThe new and improved Hydromatic Brakes are as easy and simple tooperate as ever. Any Driller can operate them without previousexperience or special training. All that needs to be done is to open orclose the valve that controls the water level in the brake circulatingsystem.Now Further Ahead Than EverToday'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 thebest auxiliary drawworks brake ever offered.
APPLICATIONSThe 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, onand off highway vehicles, gravity conveyors, dynamometers, deep wateranchor handling, and many others. Any equipment which generates asurplus of energy on descent can profit from the smooth, fluid action,"power absorbing" efficiency of the Hydromatic Brake orHydrotarder.
Because of the special nature involved in most other areas, such asvehicle applications, dynamometers, etc., no attempt has been made toinclude detailed information for design in this catalog. It is suggested thatfor any proposed application of this nature, our Engineering Departmentbe contacted.
CLEAN FRESH WATER REQUIREDA Hydromatic Brake must have an adequate circulating system
that will provide cool water at all times for the loads that it will be requiredto handle. It is imperative that the water used in the circulating system befresh and free of all foreign substance. Experience has proven thatbrackish or corrosive water, when used in the circulating system, causescorrosion that accelerates cavitation and erosion within a brake.
NO SPECIAL CARE REQUIREDWhen a Hydromatic Brake has been properly installed, it requires
no special care. It should be inspected at regular periods, such as shouldbe done with the entire rig. Each grease fitting on the brake should belubricated with a good grade of No. 2 waterproof grease equivalent oneach round trip before starting in the hole. It is recommended that sametype waterproof grease be used consistently, as some types are notcompatible with others.
CIRCULATES OWN WATERThe rotor in a Hydromatic Brake is also designed to serve as an
impeller for discharging heated water at the discharge ports. The rate ofdischarge is approximately the same as the rate at which cool waterenters the brake, provided the discharge line from the brake is notrestricted.
During the running in of a stand of pipe with a Hydromatic Brakerevolving in the direction to create resistance, a sufficient volume of coolwater must be available at the brake inlet, at pressures between theminimum and maximum recommended, to displace the water in thebrake as it is heated.
Almost Impossible to FailThe new, improved Hydromatic Brakes are practically 100%
failure proof. As long as the water supply to the brake is not interrupted, itis practically impossible for anything to get out of order in the brake or forthe brake to fail.Greater Capacity and Safety
The chief improvement in the new Hydromatic Brakes is theirincreased capacity. Their greater capacity for handling heavier loads atlower speeds steps up drilling operations and provides safer workingconditions than ever before.Ask Your Drawworks Manufacturer
If you are operating a rig without a Hydromatic Brake, or areconsidering buying a new rig, ask the manufacturer about installing aHydromatic Brake. Manufacturers will be glad to recommend the sizebest suited to your needs. All of them know and recommend theHydromatic Brake and are prepared to install it before your drawworksleaves the factory.
FUNCTION OF CIRCULATING SYSTEMPressures in excess of those recommended will NOT increase the
resistance capacity of a brake, but will cause rapid wear on the sealingelements.
Since all of the mechanical energy absorbed in a HydromaticBrake appears as heat in the water, it will be apparent that the primaryfunction of a Hydromatic Brake water circulating system is to supplycool water through the inlet of the brake to displace the heated water andthus prevent the formation of steam within the brake; also to remove theheated water from circulating system or dissipate the heat that is in it.
The secondary function of a Hydromatic Brake water circulatingsystem is to provide controls to permit the driller to vary the brakecapacity to meet the rig requirements. The capacity at any speed isadjustable by regulating the quantity of water being circulated betweenthe vaned pockets of the rotor and stators in the working chamber.Depending on the type of installation, infinitely close regulation orregulation in any desired number of steps may be obtained by varying therate of flow into the brake or varying the level of the water in thecirculating system and standpipe, dependent on the type of brake andtype of circulating system.
Any circulating system used must include a means for dissipatingthe heat from the circulating system at the rate at which it is generated inthe water by the retardation of the brake. Heat dissipation may beaccomplished by the use of heat exchangers, or by providing a sufficientsupply of fluid to act as a heat sink.
WINCH / WINDLASS SYSTEMS WITHPARMAC AUXILIARY BRAKE FOR DEEP
WATER ANCHOR HANDLINGThe Parmac Hydromatic Brake can be used both to control the
lowering of anchors from a work-boat, and to control the anchor chainpayout during the positioning of the anchor from the rig. When used inconjunction with large anchor handling winches or windlasses, thepower absorbing ability of the Hydromatic Brakes results in betterperformance, improved control and smoother operation.
At 200 feet per minute, the Parmac Hydromatic Brakes assist insafely making the anchor descent rate three times faster than otherequipment being used today.

Brakes are furnished with special shafts to customer's specifications upto 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 forbetter sealing and longer seal life, which also simplifies theirreplacement.
Some of these new models offer easier controlability, and will fit inthe old cradle without modification.
When the Hydromatic Brake was first used on drilling rigs forfaster 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 weightrequirements.
