According to its working principle, the sewage lift pump can be used as a single device or duplex equipment for the discharge of fecal water in homes, buildings, restaurants, hotels and hospitals, and all the sewage can be lifted and discharged to the nearest sewer.
At present, there are generally two kinds of working principles of the more popular sewage lifting pumps, and in the family, in this case, most of them will use non-clogging impellers. During the renovation of an old building, the waste water may not be directly discharged to the sewer pipe by gravity. In order to discharge sewage into the sewage pipe with a small diameter, the cutter or crushing device at the inlet of the pump will break up solid substances such as feces and toilet paper, and can be used as a sewage pump with a cutting device.
The sewage lift pump is a fully automatic drainage system. There is a sensor in the water storage bladder, and the change of liquid level in the water storage bladder will be transmitted to the sensor, and the control device can realize the start and stop of the crushing and cutting sewage lifting pump and monitor the field section pump. The hydraulic device of the small sewage lift pump is installed in the water storage bladder, and the hydraulic device of the large sewage lift pump is installed outside the water storage bladder.
A surface-cooled three-phase AC motor or an AC motor can be used as an attachment device.
In addition, in buildings, restaurants, hotels, hospitals and factories, the plunger of the sewage lift pump is driven by the eccentric rotation of the pump shaft, reciprocating, and its suction and discharge valves are check valves. When the plunger is pulled out, the pressure in the working chamber decreases, the outlet valve is closed, and when the pressure is lower than the inlet, the inlet valve opens and the liquid enters; When the plunger pushes inward, the chamber pressure rises and the inlet valve closes, and when the outlet pressure is higher than the outlet, the outlet valve opens and the liquid is discharged. When the transmission shaft drives the cylinder block to rotate, the swash plate pulls or pushes the plunger back from the cylinder block to complete the suction and sewage process.
The oil in the working chamber composed of plunger and cylinder bore communicates with the suction and discharge chambers of the pump respectively through the oil distribution pan. The variable mechanism is used to change the inclination angle of the swash plate, and the displacement of the pump can be changed by adjusting the inclination angle of the swash plate.
The working principle of Zede microboy household sewage lifter is that after the sewage of the bathroom enters the sewage lifter through the inlet pipe of the sewage lifter, the pneumatic pneumatic level switch in the household sewage lifter should push the pressure in the controller to rise and promote the controller to work, and then turn on the power supply of the sewage lifting pump, after the sewage lifting pump power is turned on, it will automatically run for sewage lifting and discharge, and the sewage in the sewage lifter is transported to the designated place through the sewage lifting pump. When the float falls down after the liquid level is lowered, the sewage lift pump will automatically stop running, and the relatively large solid impurities in the sewage will be cut into fine particles by the cutter of the sewage lift pump and discharged along with the sewage.
Because the sewage lifter of external registration has a good effect on the sewage discharge, which is conducive to the treatment of sewage, so it is better to prevent the pollution of sewage.
According to the size of the toilet and the number of pits, you can match and purchase a suitable sewage lifting pump. >>>More
The toilet sewage lifter with built-in pump can be extracted from the distinction for maintenance
The built-in pump sewage lifter is the pump, and the control equipment are installed in the collection tank; Although the pump and control equipment of the external pump sewage lifter and the water collection tank are a set of systems, they are installed separately outside the water collection tank. Because the motor and control equipment are installed in the water collection tank, the built-in pump sewage lifter has the shortcomings of low safety, poor sealing, small water tank volume, and high difficulty in maintenance when used, and the built-in pump is strictly forbidden to be used for discharging sewage containing feces in Europe. External pumps don't have these problems, but they are more expensive.
