vacuum pump in sewage lifting device

The application of vacuum pump in sewage lifting device can effectively solve or avoid the problems existing in traditional sump. Sewage lifting device is a set of system composed of rotary vane vacuum pump, water collecting tank, control device and relevant pipe fittings and valves, which is used to lift and transport waste water lower than the sewer or far away from the municipal pipe network. The material of the water tank of the sewage lifting device generally has corrosion resistance, anti-aging ability, long service life, and reduces the risk of customers paying extra maintenance costs and repeated purchases.

Next, East EVP vacuum pump manufacturer will introduce the working principle and use of sewage lifting device.

sewage lifting device working principle :

The waste water flows into the water collecting tank through the inlet of the whole set of equipment. After reaching the start-up water level of the equipment, the equipment will start automatically and lift the sewage to the municipal pipe network. In the sewage lifting device, the water collecting tank replaces the traditional sump. In addition to the inlet, outlet and ventilation openings, the water collecting tank is completely sealed, waterproof and anti odor leakage, so the sewage of the water collecting tank has no contact with the soil, and the peculiar smell will not diffuse in the equipment room due to the leakage, so as to completely avoid the pollution of the natural environment and provide a relatively comfortable working space for the maintenance and repair personnel. The volume of water collecting tank is much smaller than that of traditional sump. In the sewage lifting device, the function of the water collecting tank is no longer to store water, but to “overflow”; the vacuum pump matched with the sewage lifting device can be started and stopped frequently with stable performance.

Once the overflow sewage in the water collecting tank reaches the set liquid level, the water pump will start to lift and discharge the sewage. The sewage is difficult to accumulate in the water collecting tank, which reduces the generation of peculiar smell. At the same time, the sewage lifting device adopts a fully closed structure, and there will be no odor leakage. The normal exhaust gas is discharged to the outdoor through the vent pipe, which will not affect people’s living and living environment Ring.

The special vacuum pump for sewage lifting device is suitable for conveying sewage and dirt with particles in chemical industry, petroleum industry, pharmaceutical industry, mining industry, paper industry, cement plant, steel plant, power plant, coal processing industry, drainage system of urban sewage treatment plant, municipal engineering, construction site and other industries. It can also be used for pumping clean water and corrosive media.

vacuum pump in sewage lifting device application characteristics:

1. The unique single or double blade impeller structure greatly improves the pollutant carrying capacity, which can effectively pass through the fiber material 5 times of the pump diameter and the solid particles with the diameter of about 50% of the pump diameter.

2. The mechanical seal is made of new hard and corrosion-resistant tungsten titanium material, which can make the pump operate safely and continuously for more than 8000 hours.

3. It has the advantages of compact structure, small volume, low noise, remarkable energy saving effect, convenient maintenance, no need to build pump house, and can work under water, which greatly reduces the project cost.

4. The sealing oil chamber of the pump is equipped with a high-precision anti-interference water leakage detection sensor, and a thermal element is embedded in the stator winding to automatically protect the water pump motor.

5. It can be equipped with automatic control cabinet according to the needs of users, which can automatically protect the leakage, leakage, overload and overtemperature of the pump, so as to improve the safety and reliability of the product.

6. The float switch can automatically control the start and stop of the pump according to the change of the required liquid level. It is very convenient to use without special personnel.

7. According to the needs of users, it can be equipped with double guide rail automatic coupling installation system, which brings more convenience for installation and maintenance, and people do not have to enter the sewage pit for this purpose.

8. It can be used in full head without overload.
