PRODUCT FUNCTION INTRODUCTION
When you flush your toilet, you probably don’t think about where the waste goes, or how it’s pumped into a sewage line. However, this is something that plays a huge role in your lifestyle each and every day. In homes that are situated below septic or sewer lines, gravity can’t be applied to move waste. That’s where a sewage pump comes in.
What is a Sewage Pump mini-station?
A sewage pump is effectively a pump that’s used to move sewage liquids and solids between one location and another. In the case of a house, sewage is usually pumped from the basement of the house into the main sewage line.
Sewage pumps can either be manual or automatic. Manual sewage pumps need to be turned on every so often, though usually aren’t recommended due to the possibility of sewage overflow. Automatic sewage pumps, in contrast, function with the help of a float switch.
How Sewage Pumps Work?
Sewage pumps are submersible or cutting pumps. They also are specially designed in order to allow solids to pass through them without clogging the pump itself. When the pump is turned on, the motor rotates the impeller, which creates enough pressure to push water into the impeller and from there into the discharge pipe.
You may wonder how the pump knows when to pump sewage in the first place, or how the sewage tank keeps from overflowing. This is largely thanks to a float switch. This switch floats upward as the number of sewage increases in the tank. Once the sewage reaches a certain level, then the float switch turns on the sewage pump, which then allows it to be pumped out of the tank.
Float Switches for Sewage Pumps
One of the most important parts of a sewage pump is the float switch, which allows the pump to actually begin pumping. When the water level reaches the preset upper limit, the pump will automatically start pumping. When the water level is below the preset lower limit, the pump will be automatically turned off to stop pumping, so that the two pumps can operate alternately, each as a stand-by; When a sewage pump fails, the equipment can automatically switch to another sewage pump without stopping work, and lock the operation of a single pump, and at the same time, an alarm will indicate the type of failure on screen.
1.Where does the water come from? Where did it go ?
The "TJWT2 series integrated sewage lifting equipment" is an intelligent product independently developed by Tianjian Company for the sewage lifting of underground toilets. The equipment only needs to be connected to the water inlet and outlet pipe and it can operate stably after powering on. convenient!
2. How to avoid the pump burned out?
The "TJWT2 series of integrated sewage lifting equipment" has changed the traditional lifting method in design thinking. It uses Tianjian's "solid-liquid separation" technology to completely separate the impurities from the sewage, making it difficult for the impeller to touch its killer: winding objects, hard objects, to ensure the normal use of the pump , to avoid abnormal damage to the pump.
3. How to discharge the debris in the tank?
When the pump is started, the debris in the solid-liquid separation device is automatically discharged to the outdoor septic tank; at the same time , a high-pressure water flow starts to wash the bottom of the water tank, so that possible fine sludge and water in the sewage are stirred Evenly, it is lifted to the outdoor septic tank with the flow of water, without manual cleaning;
4. How to avoid overflowing odor?
We all had the experience that the toilet at home could not be flushed in time when the water was cut off: when we waited to flush again the next day, we found that the toilet smelled bad because the feces were fermented. Therefore, the "TJWT2 series of integrated sewage lifting equipment" considered at the beginning of the design that the volume of the water tank should not be too large, and then the stainless steel linkage type liquid level gauge was controlled to discharge sewage and dirt in time to avoid long-term fermentation. Coupled with sealing rubber pads and ventilation measures, the equipment works without peculiar smell.
5. How to control the work of the equipment?
"TJWT2 series integrated sewage lifting equipment" adopts intelligent control mode to automatically run: when the water level reaches a high level, the water pump starts to drain, and when it reaches a low level, the pump stops; when the next start water level is reached, another water pump starts to drain. The two water pumps are switched alternately and stand by each other, which is safe and reliable.
1. What is the relationship between the solid-liquid separation device and the volume of the water tank?
Tianjian brand "TJWT2 series integrated sewage lifting equipment" was designed and passed a very strict hydraulic model test: when the debris in the solid-liquid separation device is stored to 1/3, the high-sensitivity stainless steel rod-type floating ball feeds back to the control System signal, that is, automatically start the water pump to drain to ensure that the solid-liquid separation device will not be blocked and avoid manual cleaning. When the solid-liquid separation device is too large or too small, the solid-liquid separation device is blocked and the toilet can not be launched in time and overflows.
2.Is there anything special about the sewage lifting pump?
Thinking of the odor,the volume of the water tank was limited. However, we know that all electrical equipment is very afraid of frequent startup. When the water pump starts frequently, the temperature of the water pump motor rises too fast, and the failure of timely heat dissipation will cause the motor to burn out. Therefore, Tianjian sewage lifting equipment is equipped with a high-insulation pump: the temperature of the pump is safe to 155℃.
3. How does the equipment work when the two pumps are started at the same time?
When the toilet drainage volume is very large at a certain moment, when one pump starts to not meet the drainage demand, the second pump will automatically start the drainage to avoid the untimely leakage of sewage discharge. At this time, the toilet drain will enter the water tank through the safety return device, which will not affect the normal use of the toilet.
4. If the water inlet check valve is stuck, will the equipment overflow?
In a very small probability, the water inlet check valve is stuck and cannot be closed normally. If the water pump starts to drain at this time, the sewage will flow back to the water tank through the safety return device. Sewage continues to enter the water tank, and when it reaches an ultra-high level, another water pump starts to drain. At the same time, an audible and visual alarm signal is issued to remind the property personnel to notify our company for maintenance in time.
