How To Judge The Performance Of Sewage Elevator

1. Head

The head of the sewage elevator refers to the height of the sewage, which is not the higher the better? Of course not, if you live in the underground layer, your room height may only be 3-5m, and then remove the pipeline loss, you only need - the actual 5-8 meters of head is enough, but need to ensure that the actual head 5-8 meters of flow can meet the use of the line, otherwise many of the head is only 5 meters, the ** flow is very small. All the choice of integrated sewage elevator must pay attention to the flow and head is the curve of change;

 

2. Flow Rate

Sewage elevator flow rate refers to the displacement of water per hour, according to your own situation to buy. If you are decorating your home of about 100 planes, and your home may only have 1 kitchen or a bathroom, then you only need to choose a common flow of 5-10mm3/h is enough, of course, if you need to add more than one bathroom, or need to discharge washing machine wastewater, you can choose a larger flow, If you have the conditions, you can also choose the sewage lifting device of Qian Cheng double pump system; It is recommended to choose the sewage elevator of Qian Cheng dual pump system in public places.

 

3. Diameter of overflow

This refers to the water pump drainage pipe can discharge the diameter of debris, is not connected to the toilet generally 10mm is enough. If the eddy current type sewage elevator is used, the minimum filtration diameter of 50mm should be guaranteed. Of course, Qiancheng cutting type sewage elevator can also be selected;

 

4. Security level

Small sewage elevator part of the protection level is IP44, of course, the higher the protection level is the better, such as the protection level is IP54, the protection level is IP68, the higher the protection level represents the higher the safety of the machine, dust and waterproof performance;

 

5. Heat dissipation

Sewage elevator in operation, when the speed is very high, the heat will be very high, heat dissipation capacity will become an important indicator to measure it, look at the material of the motor and motor housing material; Generally have the conditions to do external sewage elevator pump enterprises are more reliable, because most do not have dry operation, can only throw the pump in the water to cool down, so see sewage lift pump is outside the water tank generally do pump is better, in the water tank pump general technical content is not too high heat dissipation is poor;

 

6. Box material

General sewage elevator box material has PP/PE/ABS, this depends on how you use, ABS corrosion resistance is perfect, HDPE material is more suitable for large box sewage elevator, try not to choose stainless steel welding box, because the stainless steel box is only 2-3mm thick, ** weld seams are split in the pump vibration work, Water leakage at any time, late maintenance is very difficult, the general popularity of big brands will choose to open the mold, one-time casting of plastic box sewage elevator, more corrosion resistance and no hidden danger of water leakage, but also because of the need to open the mold, investment is large, the need for certain technology, so the basic plastic box is a well-known factory to have the conditions!

 

7. Start control

That is to say, sewage elevator is started under what circumstances, how to control, now on the market to liquid level control, pneumatic control is the majority. Small sewage elevator ** is pneumatic, pneumatic control of sewage elevator, it will not cause the problem of floating ball entanglement and can not start, is more accurate control. Commercial sewage lifters ** Use liquid level control to discharge waste water containing fixed particles, such as feces.

 

These are more important to buy sewage elevator common sense, in addition to these aspects, we also need to consider the factors when choosing:

8. Maintenance is difficult

Sewage elevator failure will occur, if there is a fault many brands open maintenance is a very difficult thing, many brands after a period of time its box wall will generally be dirty. Mainly look at the installation position of the pump, the general pump outside the sewage elevator box is easy to maintain, because the maintenance does not need to open the box; Of course, the price of external sewage upgrading equipment is much higher than the built-in, because the performance of the external pump is excellent enough, the whole machine manufacturing cost is higher; At the same time to see whether the equipment with backwashing function, if not with backwashing recommendations carefully choose, otherwise later cleaning their headache!
