Application
The products that coupled with electrical alarm signal realize remote control.
The products are apt for electrical equipments such as gas or liquid insulate transformer, instrument transformers, on-load-tap channel switch, high voltage switch etc.
Once there's something wrong in such electrical equipments, valve open and relieve the pressure to avoid oil basin from metamorphose and blowout.
With the pressure reduced the valve automatically closed to prevent water and impurity got in from outside.
Working conditions and install mode:
Environment temperature - 30º C~40º C

Installation site
A) Install in the oil basin to cover
B) Install in the oil basin to sidepiece upside
C) Install in lift pedestal Alarm and Enviroment
Install, Using, Debugging Install: Pressure releasing valve and tank connect with the stud bolt

Attention:
1) The bottom of pressure releasing valve assemble to seal well;
2) When connect the pressure releasing valve and tank, tighten the bolts equality, avoid that valve pedestal rupture.
L Using: With latching that must be removed before equipment circulate;
Insure the normal work of the pressure releases valve.
L Debugging: Electric alarm switch, should manual debug deferent signal of switch whether exactitude, sensitive, before the equipments circulate.
L Method: 1)Measure export signal of switch when pressure releasing valve action less by multimeter to see whether in accordance with the signal mark of the switch.
Viz.: (a) "Common" towards "Normal open" normal open
(b) "Common" towards "Normal closed" normal closed.
2)Experiment of simulate releasing valve's action, checkout whether inching switch accurate export behavioral signal. Method: Raise the small red hat of the pressure releasing valve, then releasing valve turn on, check whether the switch measure of the electric signal change.
Viz.: (a)"Common" of switch towards "Normal open": "Normal open" should turn to "Normal closed" (b)"Common" of switch towards "Normal closed": "Normal closed" should turn to "Normal open"; (c)Examine the signal switch and control circuit connect whether right and good. L Attention: The small red hat must be replacement after test over, insure that the pressure releasing valve normal working and warning. Application

Vertical Lathe

A lathe is used to fashion a rotating piece of raw metal, wood, or composite into a precise configuration using movable cutting tools, or bits set to varying depths. The process, known as turning, or machining, is most often accomplished with a horizontal lathe. Often, however, space or material constraints, sometimes even personal preferences, necessitate the use of a vertical lathe.
Essentially a horizontal lathe turned on end, a vertical lathe, also called a boring tool, is composed of basically the same parts as a horizontal lathe. As implied, the functions of vertical lathes are performed up and down, rather than side to side, as is the case with horizontal lathes. This vertical alignment allows short, heavy, bulky materials to be machined more efficiently than with a horizontal lathe.
All lathes, vertical or horizontal, are comprised of the same basic parts. The headstock encloses the spindle and chuck, the parts that actually turn the material. The bed catches the shavings, and also serves as a brace for the horizontal lathe. The feedscrew and leadscrew, mounted on the lathe carriage, adjust the speed and distance traveled by the cutters along the stock. The cross slide and compound rest position the toolbox, which, in turn, mounts the bits.
The tailpost, at the opposite end of the lathe spindle, clutches the stock and braces it, thus eliminating wobble and vibration. The headstock and tailpost may be at the upper or lower end of a vertical lathe, or to the right or left end of a horizontal lathe. Either way, the headstock is one end of the lathe, the tailstock, the other.
Vertical lathes may be vertical turret lathes (VTL), where a turret holds various toolboxes, allowing little wasted time resetting bits during the machining process. There are also computer numerical control (CNC) vertical lathes in which the entire machining process is computer operated.
The top of the lathe pyramid are the CNC vertical turret lathe machines, most often used to turn stainless steel into precision parts for engines, turbines, transmissions, etc. These machines, though expensive to purchase and operate, are perfectly suited to the task, saving space, as well as over-stressed equipment. A CNC VTL can also be used on alloys to efficiently turn precision bearings and gears.
A vertical lathe can used on rough wood in a home workshop, mainly for its space-saving attribute. Many home hobbyists, however, simply feel more comfortable turning wood up and down, rather than side to side. Altogether, the vertical lathe is a very capable and versatile tool.
