Description
Technical field
The utility model is related to a kind of cooling water circulation field, more particularly to a kind of online pressurized backwash device.
Background technology
As shown in Fig. 2 being currently used for power plant firepower unit circulation-water pump electric machine a guide bearings and thrust bearing cooler
The cooling water of b, is directly to be formed by connecting by the waterpipe arrangement of single flow direction, once rainy season water quality is poor and hot weather
When, cooler is easily blocked, it is necessary to timely termination of pumping or pump is cleared up, it is to avoid influence unit safety problem.
At present, maintainer can only be processed by the following two kinds of programs：First, tissue manpower is by circulation-water pump electric machine
After the cooler of flush type is removed, it is rinsed with giant and compressed air, then carries out back dress；2nd, organizer
Power the import and export cooling water pipe of circulation-water pump electric machine intercooler is removed after reversal connection, then carried out using former cooling water
Backwash, because cooling water pump is long-axis vertical water pump, continuous operation troubles takes place frequently, and maintenance workload is big, even in reversal connection
Be also required to during flushing it is regular carry out Disintegration overhaul, often can only export cooling water branch pipe using other circulation-water pump electric machines
The low discharge of offer, the water resource of low-pressure carry out backwash, have a strong impact on circulation-water pump electric machine cooling and require.
Although it can thus be seen that such scheme one use dismounting after cleaning way can reach expected cleaning performance,
But either scheme one or scheme two, it is necessary to which water circulating pump power failure operation, maintainer's workload are switched by operations staff
Greatly, overhaul uneconomical.
Utility model content
The purpose of this utility model is to provide a kind of less investment, and cooling water flow is big, cooling water pump online backwashing effect
Fruit gets well and the short online pressurized backwash device of run time.
The utility model provide this online pressurized backwash device, including cooling water pump, installed in water circulating pump electricity
Cooler, backwater main pipe and water inlet main pipe in machine, the device also include inlet valve, secondary inlet valve, an outlet valve
Door, sewage draining valve and contact valve, the cooling water pump and water inlet main pipe pass through an inlet valve and secondary inlet valve
Connected with cooler inlet, the cooler inlet is connected with sewage draining valve, cooler outlet is by flowing water Valve and backwater main pipe
Connection, contact valve is communicated between cooler outlet and an outlet for inlet valve, the cooling water pump, a water intaking valve
Door, contact valve and sewage draining valve open the control online pressurized backwash of cooler, an inlet valve, secondary water intaking valve
Door and flowing water Valve open control cooler work.
For convenience of the stoppage in transit maintenance of cooling water pump in the utility model, an outlet valve is provided with the cooling water pump.
The cooler is using snakelike.
The outlet of the sewage draining valve is connected with trench.
To prevent the aqueous reflux in the utility model water inlet main pipe to cooling water pump, it is caused to damage, in the cooling water
Pump is provided with a reverse stop valve.
Compared with prior art, the utility model has the advantage of：
1st, divided by secondary inlet valve and an inlet valve by by the cooler inlet of existing circulation-water pump electric machine
Do not connected with water inlet main pipe and cooling water pump, and cooler inlet is connected with sewage draining valve, cooler outlet is passed through into water outlet
Valve is connected with backwater main pipe, and exports a contact valve of connecting with an inlet valve in cooler outlet, and operations staff can
According to live bearing temperature measuring point trend, directly replace maintainer, switched by the cooperation of each valve, using cooling water pump
Cooling water is directly backwashed to cooler, and will rinse impurity extraction, not only reduces the amount of labour, also improves cooler
Cleaning inside degree, it is ensured that the heat transfer effect of cooler, it is ensured that the reliability of water circulating pump；
2nd, intermittent operation pressurization is carried out when bearing temperature is high using existing cooling water pump, when not only increased operation
Cooling water inflow, for big flow, high pressure backwash provide guarantee, simultaneously as the cooling water pump of longtime running is changed into interval
Property force (forcing) pump, improve backwash source pressure and flow velocity while, reduce equipment operation power consumption.
The utility model utilizes original resource by site inspection and reasonably, is not increasing the premise of any energy consumption equipment
Under, while reducing the cost of overhaul and operation power consumption, improve the simplification of operating process and the reliability of equipment.
