problem of odor outright:
the traditional sanitary appliance is of a water flushing type, part of odor can still be retained in air, negative pressure is absorbed from outside to inside, and odor cannot be diffused into the air. Thoroughly solves the odor problem of the toilet with small space and unsmooth air.
The water for flushing the toilet can be greatly saved:
the traditional water-saving toilet specified by the state is 4L/time, and after a vacuum pump station is adopted, the toilet flushing is performed for less than 0.5L/time each time;
(III) simplified installation procedure, cost saving:
because the negative pressure is a power source, the pipeline installation process can be along the linear and curve trend of the outside and the inside of the structure, even the upper and the lower trend has no problem, and the traditional gravity flow is difficult to realize. In addition, the conveying pipe diameter can be greatly reduced due to the adoption of a negative pressure source.
(IV) the blockage is not easy to happen, and the operation is stable:
and fifthly, the vacuum degree of-40 to-80 kpa is adopted to ensure that enough power is available for conveying the raw water.
And sixthly, after the novel vacuum pump station is started for the first time, the whole operation process can be controlled fully automatically. In the working process, the vacuum degree of each position in the vacuum system always fluctuates up and down within the allowable range, and the fluctuation range can be adjusted according to the requirements of users. If the vacuum degree is lower than the set value, the alarm gives an alarm.
And (seventhly), the novel vacuum pump station automatically controls the system under the unmanned operation condition, and the vacuum system can be automatically closed when power is cut off.
And (eighth), the novel vacuum pump station is provided with a gas-water separator, so that water sources can be saved, and environmental pollution can be reduced.
The vacuum tank of the novel vacuum pump station can be designed into a horizontal structure or a vertical structure according to the field design, and the installation is more flexible.
