We often think about how to deal with the rainwater on rainy days, the sewage from the construction site, and the sewage from bathing. How is the dirty water discharged into the city’spipelines? The editor tells you that the sewage treatment and To discharge, we need to use our professional sewage treatment equipment-sewage lift pump. And what kind of sewage lift pump is a good sewage lift pump, how should we choose the brand of sewage lift pump. The following is an explanation for you to judge the quality of sewage lift pump through nine performances.

First, flow

The flow rate of the sewage lift pump refers to the displacement per hour, which can be selected according to your own situation. If you are decorating your home of about 100 square meters, and you may only have one kitchen or one bathroom in your house, then you only need to choose a normal flow rate of 5-10m³/h. Of course, if you need to add more than one bathroom , Or need to discharge washing machine wastewater, etc., you can choose a larger flow rate, if you have the conditions, you can also choose a sewage lifting device with a double pump system; it is recommended to choose a sewage lifting pump with a double pump system in public places;

Second, head

The lift of the sewage lift pump refers to the height of the highest sewage lift. Is this the higher the better? Of course not. If you live in the basement level, your house may be only 3-5m high. After removing the pipeline loss, you only Need-the actual head of 5-8 meters is enough, but it is necessary to ensure that the flow can still meet the use when the actual head is 5-8 meters, otherwise many maximum heads are only 5 meters, and the final flow is too small. All options The integrated sewage lifting pump must pay attention to the changing curve of flow and head;

Third, the flow diameter

This refers to the maximum diameter of debris that can be discharged from the water pump drainage pipe. Generally, 10mm is sufficient if it is not connected to the toilet. If the vortex type sewage elevator connected to the toilet needs to ensure a minimum filter diameter of 50mm, of course, you can also choose a cutting type sewage elevator;

The above are the three most important parameters of the sewage hoist. The next question is how do we judge the quality of the sewage hoist? This involves other parameters of the sewage hoist.

Fourth, security level

Part of the protection level of the small sewage lift pump is IP44. Of course, the higher the protection level, the better. For example, the protection level is IP54, and the protection level is IP68. The higher the protection level, the higher the safety of the machine, which is dust-proof and waterproof. performance;

Fifth, the box material

Generally speaking, the box material of sewage lift pump is PP/PE/ABS. It depends on how you use it. ABS has the highest corrosion resistance. HDPE material is more suitable for sewage lifts with large boxes. Try not to choose The stainless steel welded box, because the stainless steel box is only 2-3mm thick, the final welding seam must be cracked during the vibration of the pump, and the water leaks at any time. It is very difficult to maintain in the later stage. Generally, the well-known big brands will choose to open the mold. The cast-molded plastic box sewage lift pump is more resistant to corrosion and has no hidden dangers of water leakage. It also requires a large investment and certain technology because of the need to open molds. Therefore, the current plastic box is basically available only by well-known large factories. condition!

Sixth, heat dissipation

When the sewage lift pump is running, the speed is very high, and the heat will be very high. The heat dissipation capacity becomes an important indicator to measure it. It depends on the material of the motor and the material of the motor housing; generally, it is possible to make external The pumps of sewage lift pump companies are relatively reliable, because most of them do not have dry operation, and can only throw the pump in the water to cool down. Therefore, the pump for sewage lift is a general pump outside the water tank. All are better, the general technical content of the pump in the water tank is not too high, but the heat dissipation is poor;

Seventh, start control

That is to say, under what circumstances does the sewage lift pump start and how to control it. Nowadays, liquid level control and pneumatic control are mostly used on the market. The small sewage lift pump is preferably pneumatic. The pneumatically controlled sewage lift pump will not cause the problems of floating ball entanglement and failure to start. It is more accurate and controlled. Commercial sewage lift pumps are best to use liquid level control to discharge wastewater containing fixed particles, such as manure.

These are the more important common sense for purchasing sewage lift pumps. In addition to these aspects, we also need to consider the following factors when purchasing:

Eighth, service life

The longer the better, because replacement and maintenance are more troublesome. Many started to buy some low-cost sewage lifting pumps from small factories in order to save costs. In the last few years, the maintenance and replacement costs have exceeded that of buying a safer and more stable one. The cost of the sewage lift pump product is high, so try to choose a well-known sewage lift pump manufacturer with more reliable performance. You cannot blindly pursue the price, otherwise you will eventually lose more financial costs.

Ninth, maintenance is difficult and easy

If the sewage lift pump fails, it will still happen. If it fails, it is very difficult for many brands to open and repair it. After a period of time, the inner wall of the box of many brands will generally be dirty. It mainly depends on the installation position of the pump. Generally, the water pump is the easiest to maintain outside the sewage lifting pump box, because it is not necessary to open the box during maintenance; of course, the price of the external sewage lifting equipment is much higher than the built-in one, because the external The performance of the pump can be excellent, and the manufacturing cost of the whole machine is also higher; at the same time, see whether the equipment is equipped with backwashing function, if it is not equipped with backwashing, it is recommended to choose carefully, otherwise it will be a headache to clean yourself later!

In fact, sewage lift pumps can also be installed in our homes, because sewage lift pumps can clean the drainage pipes and remove the waste water and excrement generated by our daily water use. When we buy a sewage lift pump, we must consider its convenience. It is best to choose a sewage lift pump that is easy to disassemble and clean, and has its own cleaning function to avoid clogging of sewage and peculiar smell in the house when it fails. It is best to choose a well-known international brand when purchasing. We not only need to look at its quality, but also understand whether it is convenient to use.
