一：Vacuum water diversion system

JMXT vacuum water diversion system is a new generation of The water pump, Vacuum water diversion product with simple structure, mature application and reasonable configuration.It is widely used in the vacuum water diversion of large pumps before mining, such as waterworks, power plants, paper mills and petrochemical industries. The traditional structure form of the bottom valve in the intake pipe of the suction pipe is completely replaced when the water pump is filled in, which can reduce the loss of the suction pipe and improve the suction performance of the pump.
JMXT Vacuum drainage system. Used in the pump room, pumping station, sewage treatment, such as vacuum water diversion and the design and manufacture of special occasions。This device is used for The water pump in The water pump station to automatically fill The water, so that all The water pump is always in a water filling state, and any one of The water pump can be started at any time.With this device, the ground pump station can realize automation operation, and can get rid of the design of the traditional semi-underground self-filling water pump station.。So can save a lot of pumping station construction costs, to avoid the Water pump flooded the possibility of improving the Water pump working conditions and the operating environment, to ensure that the Water safety Water supply pump station, the device is good airtight performance, high degree of automation, convenient operation, safe and reliable work.

二：Vacuum water diversion system Working principle

The vacuum drainage system consists of two JBV water ring vacuum pumps, a vacuum tank, a circulating water supply tank, a set of pipeline valves and a set of electrical automatic control distribution boxes，With vacuum tank as the vacuum equipment package system, vacuum pumping station in all Water pump are installed at the top of the vent one-way valve (is beyond the scope of distribution device, need further preparation) are connected to the vacuum storage tanks and pipes.The one-way valve is used to make the air in the pump freely enter the vacuum box, and the water can not pass through the check valve.The opening and stopping of the centrifugal pump is controlled by the central controller through the solenoid valve and the flow switch on the vacuum pipeline, and the electromagnetic valve is normally closed.，The central controller needs to start the centrifugal pump，First open the solenoid valve and start the centrifugal pump at the same time，The vacuum tank is equipped with an automatic signal generator.Vacuum equipment works automatically according to instruction。When the vacuum degree of the vacuum system is lower than the lower limit，Prompt stop instruction vacuum device to stop automatically.The working fluid can be recycled，The system greatly reduces the consumption of working fluids and environmental pollution.So the suction gas is poisonous，It has obvious advantages in various occasions such as removing gas containing organic solvents.，Water is used as the medium in the working fluid in this system.

三：Product characteristics of vacuum system

1. High vacuum degree, stable performance and long life.

2. flow: 4-1300m3/hr (single pump)

3. vacuum usage: 0.5-500mbar (absolute pressure)

4. there is no need to access the water source

5. Compact structure, covering an area of small.

6. Easy maintenance and low noise.

7. PLC control of multiple units can be realized.

8. Connect to GDMS system.

四：Working principle of vacuum system：

First set the upper and lower limits of the vacuum system（For example, the upper limit is set to -0.08MPa, and the lower limit is set to -0.06MPa.),After starting the system，One of the vacuum pumps began to work.，The vacuum degree in the vacuum tank is higher than the upper limit of -0.08MPa，The vacuum pump will stop running automatically at this time，The vacuum in the vacuum tank is automatically cut off from the vacuum check valve，If the working requirements are met, the vacuum degree in the vacuum tank can be reduced to -0.06MPa below the lower limit.，Another vacuum pump starts automatically until the vacuum level reaches a maximum value over a certain time.，And a single vacuum pump can not reduce the vacuum in the tank above the lower limit.，Another vacuum pump will automatically start until the upper limit is exceeded.
