1、 Overview of integrated sewage lifting device (device, equipment) products
 The integrated sewage lifting device (device, equipment) solves the disadvantage of the traditional Cesspit (box) equipped with sewage pump in the basement. When the basement sewage cannot flow into the outdoor sewage pipe network by gravity, the traditional solution is to set a Cesspit (box) equipped with sewage pump in the basement. However, this form of sewage pressure discharge has many drawbacks, such as the easily clogged debris in the sewage, which must be regularly cleaned and crushed. Even so, it is difficult to avoid damage to the sewage pump due to blockage, and the odor emitted by the sewage during the cleaning process pollutes the surrounding environment, which is even more unacceptable. The successful development and promotion of this equipment have fundamentally solved the drawbacks of sewage discharge in existing underground buildings. Traditional sewage pits can emit odors that pollute the environment, leak and erode underground building foundations, making them difficult to clean, easily clogged, and have a high failure rate.

2、 Working principle of integrated sewage lifting device (device, equipment):
The fully automatic basement sewage discharge equipment mainly consists of a collection (sewage) water tank, a lifting pump, an auxiliary sewage pump, a control cabinet, and corresponding filters, pipelines, valves, etc. When sewage enters the equipment through the system pipeline, it first passes through the 1 # and 2 # check valves and filters, while filtering out impurities greater than 5mm, and enters the collection tank. When the sewage in the collection (sewage) tank reaches the set Z-high water level, the liquid level controller sends a signal, and the control cabinet starts the 1 # or 2 # system to start drainage. At this time, the pressurized sewage passes through the filter in the opposite direction, playing a backwashing effect on the filter, Under the pressure of water, if the check valve is closed or the 2 # system is closed, open the check valve 3 or 4 to discharge the sewage outdoors. When the 1 # system discharges water, it does not affect the inlet of the 2 # system. It can still enter the water collection tank through the open check valve T or 2, which does not affect the working water pump to lift the sewage. When the sewage in the collection (sewage) tank decreases and the water level drops to the set low water level, the liquid level sensor sends a signal to the control cabinet, instructing the lifting pump in operation to stop running. An automatic program has been set in the control cabinet, and the lifting pump and 2 # are standby for each other. They can automatically switch on and off alternately, and can also be started at the same time when the water level is too high. Full automatic operation does not require the supervision of a dedicated person. When the equipment malfunctions, the alarm system will automatically start, the alarm indicator light will flash, and an alarm will be issued to remind the user. The control cabinet is equipped with a manual operation system, which can also manually start and stop the water pump on site. In addition to dual pump control, the equipment also has single pump and four pump configurations. Single pump configuration equipment; Therefore, it is only limited to occasional discharge of sewage in underground plugs, and the discharge pattern can be controlled, and the sewage volume must be less than the lifting capacity of a single pump. The prisoner pump configuration is a dual use and dual backup lifting pump, suitable for high flow of sewage during peak hours. Due to the large flow rate of sewage entering the collection tank, the flow interface is correspondingly expanded when equipped with four pumps, and the accepted sewage flow rate is also correspondingly increased. When one lifting pump is running, it will not affect the water inlet of other inlet ports. As the water level in the collection tank increases, under the control of the control cabinet, at most two of the four pumps Z can be started successively, To meet the varying sewage flow rate. Four pumps are used alternately as backup for each other.

3、 Application field of integrated sewage lifting device (device, equipment):
1. Building basement.
2. Underground shopping malls, hospitals, chemical plants, underground garages, and large, medium, and small hotels.

4、 Technical parameters of integrated sewage lifting device (device, pump, equipment):

1. For the lifting of ordinary domestic sewage and the lifting and discharge of various sewage, the Construction waste in the pipeline must be removed before the use of new buildings.
2. The pH range of sewage is (pH~2).
3. The temperature of sewage is between 0 and 40 "C.
4. The power supply is 380V (± 5%), 50Hz.
5. Sewage density transport 1600kg/m2 0
6. All sundries that can flow freely in the sewage pipe can be discharged.
7. The equipment operates in an environment with a humidity of less than 90%.

5、 Characteristics of integrated sewage lifting device (device, pump, equipment):

1. 304 stainless steel box: It has characteristics such as seismic resistance, corrosion resistance, no leakage, beautiful appearance, and long service life; 
2. Closed box: The water tank is fully enclosed and equipped with a dedicated inspection movable closed cover plate to ensure that the equipment is free from odor and odor, and that there is no overflow of sewage inside the box;
3. Adopting a cutting sewage pump: The sewage lift adopts a safe and reliable high-quality sewage pump, which can ensure smooth drainage, reduce usage and maintenance costs, and break the disadvantage of relying on imported cutter pumps for sewage lifting, which is prone to entanglement and blockage;
4. Split type debris separation device: The split type debris separation device achieves the separation of debris and sewage. The debris enters the debris separation device through the inlet pipeline and is temporarily stored in the debris separator. The sewage normally flows into the closed box, and the debris does not contact the sewage pump impeller. When the sewage pump is working and draining, the temporary debris stored in the debris separator is taken away through the drainage pipeline using the drainage water pressure of the sewage pump, and discharged into the municipal pipeline network. Completely eliminating the use of a cutter pump to solve blockages, but the occurrence of pump entanglement and pump jamming during shutdown;
5. Seamless steel pipe material: All pipes are made of seamless steel pipe.

6. Fully automatic intelligent control: Adopting fully intelligent control technology, manual and automatic conversion reduces the difficulty and intensity of manual control. The unique design mode ensures the normal and safe operation of sewage lifting equipment in various usage environments, and has an alarm prompt function to ensure the continuity of user use;
7. Excellent equipment technology: The production process of the sewage elevator is excellent, which determines the stability of the overall operation of the equipment and ensures a low failure rate in application.
