The benefits of using vacuum system _ in the vacuum drainage system

in the most scientific and reasonable use of sewage treatment in outdoor, we how to use the vacuum drainage system? Vacuum drainage system is one of China's a new type of drainage system, applicable to the basement and other places with special requirements for installation and health. Although 20% ~ 30% more expensive than traditional drainage method, but in water saving, environmental protection and operation maintenance aspects has obvious advantages. Small make up vacuum system will be introduced in the application of the vacuum drainage system.

vacuum drainage system by the sewerage Wells, vacuum contact initiating device, vacuum drainage pipe network, vacuum equipment, station monitoring system, etc. System work through the various sewerage Wells in the contact vacuum starter automatic opening and closing to control, under the effect of vacuum negative pressure, the wastewater can be vertical was promoted to trunk sewer or sewage treatment plant.

why choose vacuum system applied in the vacuum drainage system? What's so special about vacuum system?

central vacuum tank is one of the only constant mechanical and electrical vacuum system, it has the characteristics are:

1 vacuum, vacuum stand upper and lower limit value, by vacuum gauge set in 0 ~ - 0. Between 1 mpa, error values in the plus or minus 10%.

2, vacuum station with propane tanks manufactured according to user requirements, usually in 0. Between 1 to 3 m3. Vacuum station starts, vacuum degree of vacuum tank always stay in setting between the upper and lower limit.

3, configuration USES the brand vacuum pump, vacuum pump according to the gas use corresponding configuration model.

4, the control mode.

A, single pump automatic and manual control.

B a to open a standby or double pump, double pump automatic cycle operation control of single water pump timing separately, or double pump linkage operation automatic control at the same time.

5, vacuum negative pressure station is provided for each pump inflatable electromagnetic valve, to prevent the vacuum oil return of failure.

6, special industry can design according to customer's requirements of metal or dust filter, effectively protect the vacuum equipment.

only constant electrical and mechanical advantage of the central vacuum station:

1. Cover a multitude of small vacuum consumer demand.

2。 Modular design, customized according to customer's specific process.

3。 The operation is simple.

4。 Save a space system solutions.

5。 Return on investment is high, good cost performance.

6。 Energy saving function.

7。 With low cost.

8。 Due to the buffer size to reduce cycle time ( Effects of infinite pumping speed) 。

9。 Complete one-stop system, can be run at any time.

vacuum collection tank to ensure that the vacuum and collect sewage. Wastewater collected at the bottom of the tank to a third place, the remaining two-thirds of place used to guarantee the vacuum degree. Vacuum collection tank connected to the vacuum tube, vacuum tube of the entrance, which is situated in the middle of the tank. Tank negative pressure generated by the vacuum pump. When negative pressure is lower than the lower limit, open the vacuum pump, when the tank pressure to set limits, vacuum pump automatically stops.

install a check valve between the vacuum pump and vacuum pump. When the vacuum pump stops running, one-way valve shut down automatically, to ensure that the tank of gas does not return. Check valves are installed on the sewage pump. When sewage water pump stop check valve will shut down automatically to prevent backflow. Vacuum collecting top also install a relief valve, in order to prevent the vacuum pump or sewage pump work, tank pressure is too large.

before using, vacuum station should be sealed. When the end valve is closed, start the vacuum pump to - The negative pressure of 70 kpa, 1 hour after negative pressure should not exceed 10%.

vacuum system in the vacuum drainage system, the application of the benefits of

1, eliminate gravity conveyor leak leakage and discharge of groundwater resources and the environment pollution, good water recycling, promote environmental protection and ecological improvement.

build gravity pumping station 2, free, no large excavation project, do not need to set a large network, greatly reduce the construction material, greatly reduce the construction quantities, greatly shorten the construction period, construction cost multiplied, advocates the implementation of resources conservation and green building method.

3, avoid conveying pipe network congestion spillover, eliminate the phenomenon of the stench, reduce network operation fault maintenance costs, improve the quality of living environment.

4, easy to realize wastewater, sewage and rainwater drainage classification and other transmission and processing, construction cost is low, can greatly reduce the drainage transport and handling cost.
