Before activation, all there is air inside steam turbine, and the pressure of body is equal to atmospheric pressure, if do not taken out for steam turbine
Vacuum, air can not just discharge, thus increase pressure at expulsion, be switched in this case, it is necessary to have very big quantity of steam
Overcome frictional resistance and inertia force in steam turbine and each bearing of aerostatic press, could get excited rotor, make blade by compared with favourable opposition
Power is hit, after rotor is got excited, since there are air in condenser, reduces heat transfer rate, cooling effect is poor, makes exhaust temperature liter
Height causes exhaust casing and inner body to deform, and back pressure increases in condenser, can also make vacuum safety valve events, so condensing-type
Steam turbine must vacuumize before activation.
The vaccum-pumping equipment of power plant units condenser is mainly using water-ring vacuum pump at present, since its is simple in structure tight
Gather, air-breathing is uniform, stable working is reliable, easy to operate, easy to maintenance, be widely used.Generally can with motor direct connection, without
Deceleration device does not have metal friction surface in pump chamber, without to being lubricated in pump, wears very little, but water-ring vacuum pump is taken out
The temperature of working solution has very big relationship in the efficiency and the pump housing of vacuum, in steam turbine of thermal power plant group, with the working time
Extend, since acting and vapor release gasification latent heat can cause working solution temperature constantly to increase, and working solution temperature can cause
Vacuum pump exhaust capacity declines, and condenser vacuum is deteriorated, and influences unit economy, while can also cause vacuum pump cavitation, influences
Safety.
Therefore, it in order to reduce steam condenser of steam turbine set water-ring vacuum pump working solution temperature, needs to propose a kind of cooling dress
It puts, that improves water-ring vacuum pump vacuumizes efficiency, it is ensured that Steam Turbine safety, economy, stable operation.
Utility model content：
The technical issues of the utility model solves：A kind of water-ring vacuum pump cooling device is provided, for solving liquid-ring type
The problem of vacuum pump fluid operating temperature is excessively high improves water-ring vacuum pump and vacuumizes efficiency.
The technical solution of the utility model：A kind of water-ring vacuum pump cooling device, including vacuum pump, moisture trap,
Cooler, water tank and water replanishing device, the vacuum pump exhaust port are connected by water pipe with moisture trap, moisture trap warp
Water pipe connects respectively with cooler and tank top, and cooler and water tank are connected by water pipe with vacuum pump fluid entrance, institute
The cooler and water tank stated also are connected with water replanishing device respectively.
The vacuum pump air entry is connected by pipeline and valve a with condenser.
Valve c is provided at the top of the cooler.
The tank top is provided with valve d.
Valve e and valve f are respectively arranged on the water replanishing device both sides outlet conduit.
Exhaust pipe is provided at the top of the moisture trap, valve b is provided on the exhaust pipe.
The beneficial effects of the utility model：A kind of water-ring vacuum pump cooling device is provided, when summer temperature is higher
The working solution discharged by cooler cooling water ring type vacuum pump exhaust port is waited, when winter temperature is relatively low, passes through water tank nature
The working solution of cooling, is then transported in water-ring vacuum pump by the working solution of cooling water ring type vacuum pump exhaust port discharge again,
Water-ring vacuum pump working solution temperature is effectively reduced, greatly strengthens water-ring vacuum pump vacuum capability, improves pumping
Vacuum efficiency makes condenser keep higher vacuum degree, it is ensured that the safe and stable operation of Steam Turbine, while profit can be recycled
The working solution excluded with water-ring vacuum pump, is effectively saved water resource.

Specific embodiment：
A kind of water-ring vacuum pump cooling device, including vacuum pump 1, moisture trap 4, cooler 5, water tank and 6 moisturizings
Device 7, the vacuum pump exhaust port 3 are connected by water pipe with moisture trap 4, moisture trap 4 through water pipe respectively with it is cold
But 5 top of device is connected with 6 top of water tank, and cooler 5 and 6 bottom of water tank are connected by water pipe with vacuum pump fluid entrance 14,
The cooler 5 and water tank 6 are also connected with water replanishing device 7 respectively.
The vacuum pump air entry 2 is connected by pipeline and valve a8 with condenser, for absorbing in condenser
Air and steam, valve a8 is used to control the break-make of vacuum pump air entry 2.
5 top of cooler is provided with valve c10, when temperature is relatively low in winter, for closing cooler 5.
6 top of water tank is provided with valve d11, when summer temp is higher, for closing water tank 6.
Valve e12 and valve f13 are respectively arranged on the 7 both sides outlet conduit of water replanishing device, for controlling to cold
