Equipment Used Afloat. Ashore Governor for Pumps--Gantry Drill Press--Engine Generator Set governor for formerly manu- the Ideal Au- tomatic Mfg. Cos has been redesigned. It is now manufactured solely by the Atlas Valve Co., Newark, N. J., whose designing engineers have developed the improvements. Figs. 1 and 2 show the two princi- pal designs. Both are made for tur- bine or reciprocating steam driven pumps. Both styles, also, are approved by the national board of supervising inspectors of steam vessels and by the bureau of engineering, navy depart- ment. The type in Fig. 1 is designed for constant or fixed pressures while Fig. 2 is made for pressures that may be varied from time to time. The governor shown in Fig. 2 is equipped with an emergency control lever which provides means for man- ually operating the governor so that it.can be held wide open or be shut off tight regardless of the pump pres- HE pump marine service, factured by sure. Where the pump must deliver an exceptionally high pressure during an emergency, or where pumps must be shut down quickly in case of fire or rupture of the pipe lines, it is' evi- dent that this lever adjusting feature is important. It is ready at all times to throw the pump in or out of serv- ice as the emergency may require. This pump governor is of the vari- able pressure type which can be ad- justed to maintain any predetermined pump discharge pressure, At the same time by manipulating the lever an al- 'most instantaneously increased dis- charge pressure is effected. This governor is piston actuated. It is extremely sensitive, with a patent- ed exclusive feature of an actuating piston operating in a bath of oil. This body of oil not only lubricates the ' operating piston but also prevents the liquid being pumped from entering the control cylinder, thus eliminating any possibility of the sticking of the piston ' due 'to corrosion or deposits of sediment. The governor is simple in construc- tion and consists of only two moving parts--the steam valve which moves backward and forward within the valve body (which is of the double seated balanced valve type), and the control piston which moves backward and for- ward in a bath of oil within the con- trol cylinder. They are installed in the feed line to the pump in a manner as indicated in Fig. 3. Fig. 3 shows the governor of the Fig. 1 type in place, so that the pump is a constant pres- sure pump. The control cylinder of this governor is connected through valve A and a pipe line to the pump discharge as plainly shown in Fig. 3. For general use, from 3% to 2-inch sizes, these governors are made of bronze throughout and for larger sizes lip to 6 imches, they are given' iron bodies, trimmed with bronze. For superheated steam, they have steel bodies and monel metal seats and stems. FIG, 1--GOVERNOR FOR FIXED TROL LEVER.
