The principle application of sewage lifter, what is sewage lifter?

The automatic sewage lifter can be used mainly for the removal of sanitary ware sewage in basements and places far away from the drainage riser and without self-flowing sewage discharge, and can also be used for ships, vehicles and other occasions where the drainage conditions are not very good.

The sewage lifter has a unique design, it is composed of two parts that can be detached, one part is the water storage bladder and the inlet and outlet pipes, it is connected with the drainage pipe of the sanitary appliances, it is fixed, and it generally does not need to be disassembled during maintenance. The other part is the cutting pump and the pressure control system, which can be easily disassembled and quickly separated for maintenance in the event of a mechanical failure.

This avoids the hassle of disconnecting the water storage bladder from all plumbing fixtures.

When the sewage lifter is placed on the ground at the same elevation as the sanitary appliance, it is suitable for the type where the toilet is a post-drainage.

In fact, the sewage lifter is composed of a complete set of sewage lifting equipment such as water collection tank, controller, motor pump, etc., which is mainly used to solve those basements or those places far away from the sewage pipeline, usually a set of overall system, which can solve the public health problems of some special places.

The traditional basement sewage is the sewage collection pit + pump sewage discharge mode, it is mainly to drain the sewage into the sump and then discharge the sewage to the sewage well near the submersible pump, of course, this sewage discharge method works hugely, and at the same time the pollution of the surrounding area is also more serious, relatively speaking, the sewage lifter is relatively simple, its working principle is that the sanitary appliances discharge the sewage into the water tank, when the sewage reaches a certain level, the lifter will automatically operate, and then the sewage inside the water tank, It is then lifted to the ground level in a designated sewage pipe, then discharged out, and then stopped when the liquid level drops to a certain level.

Sewage lifter, simply put, is a pump product that discharges sewage, which is different from the well-known clean water pump, and the water discharged by the sewage lifter is sewage.

Generally, it is aimed at places lower than the main sewage pipe, and the sewage cannot flow naturally into the main sewage pipe, so the sewage lifter is required to pump the sewage to a certain height first, and then let it flow into the main sewage pipe.

Since it is sewage, it involves a problem of impurities, and domestic sewage, such as the water generated by kitchens, bathrooms, etc., needs to consider a problem of overflow diameter. Either the diameter of the overflow should be large, or it should be equipped with a cutting and crushing device to ensure that the sewage discharge is smooth and not blocked.

The sewage lifter is used in places where sewage cannot be discharged naturally to improve the discharge of sewage, for example, the microboy is placed in the basement bathroom to improve the toilet sewage, and the SWH is placed in the basement kitchen to lift the discharge of basement kitchen sewage, which is very simple, it is to improve the sewage in places where the sewage cannot be discharged naturally.

In fact, there are two ways to install the sewage lifter at home, one is surface-mounted, placed on the ground, we can see, like most of the installation methods of small sewage lifting on the market belong to this way, especially the sewage lifter connected to the toilet, 80% of which need to be installed behind the toilet, of course, there are some equipment that can be buried in the wall of the installation, of course, this situation has high requirements for the waterproof of the equipment, not all equipment meets the requirements, After all, the waterproof level of small sewage lifters on the market is generally not high, like this directly connected to the rear toilet, as long as the water inlet and outlet pipe are connected with the water inlet and outlet of the machine, the installation is actually very convenient in general, and the general hydropower master can easily solve it.

The other is installed in the basement of the special pit, this kind of machine waterproof level requirements are relatively high, if there is no IP68 protection level, then do not consider, because once the machine motor into the water, interference, the damage is great, so the gain outweighs the loss, in addition to the installation process to try to ensure that the pit is dry, must do a good job of waterproofing, to prevent the sewage lifter from soaking in water, resulting in motor failure. At the same time, it is necessary to pay attention to the maintenance problems in the later stage, and leave the inspection port for the working pit.

When the external sewage lifter is installed in the foundation pit, it is necessary to install a hand-cranked diaphragm pump and a foundation pit auxiliary sewage pump; The working principle of the hand-cranked diaphragm pump is that when the pump fails, the sewage in the box needs to be discharged manually, otherwise the sewage will overflow when the pump is turned on, and it is difficult to clean up; The function of the auxiliary sewage pump is that when the water seepage in the foundation pit or the condensate in the foundation pit accumulates to a certain height, the sewage pump needs to discharge it, otherwise the box will be floated, resulting in the rupture of the drainage pipe and the inlet pipe, and the overflow of sewage; If the sewage overflows, it will seriously pollute the surrounding environment, and at the same time, it will bring great difficulties to after-sales service.

The built-in sewage lifter is also installed in the foundation pit to install the sewage auxiliary pump, and some of the built-in sewage lifter are equipped with a high level alarm float in the box, and there will be no sewage overflow when the upper cover is opened to overhaul the pump, and there is no need to install a hand-cranked diaphragm pump.

The built-in sewage lifter is also installed in the foundation pit to install the sewage auxiliary pump, and some of the built-in sewage lifter are equipped with a high level alarm float in the box, and there will be no sewage overflow when the upper cover is opened to overhaul the pump, and there is no need to install a hand-cranked diaphragm pump.

In order to solve the problem of condensate in the foundation pit, a secondary floor drain can be installed on the surface of the backfill of the equipment, which can lead the condensate back to the box.

There are two common ways to do this:

One method is to set up a sump under the basement ground, collect the sewage of sanitary ware together, and use a submersible sewage pump to lift and discharge to the outdoor underground sewage pump well;

Another method is to discharge the sewage from the toilet into the outdoor underground sewage pump well, and use the submersible sewage pump to lift and discharge it into the sewage inspection well near the pump well.

There are three drawbacks to the first method:

First, there are solid substances such as feces in sewage, which are easy to cause blockage if they are not cleaned up for a long time;

Second, due to the shallow sump, the operation of the submersible sewage pump that starts and stops according to the water level is not very reliable;

The third is that the airtightness of the sump is not good, there is an odor, and the sanitary condition is not good.

The second method is to build a pump well outdoors, which is deeper, the investment is larger, and the management is not convenient. In addition, the toilet in the building is set up up and down dislocation, so that the toilet is far away from the drainage riser, but the drainage riser can not be suspended under the floor again, and the commonly used method at this time is to thicken the floor cushion, and the drainage branch pipe is buried in the cushion and discharged into the drainage riser from above the floor slab with a certain slope. In this way, the thickness of the cushion is thicker, sometimes up to 350 400mm, which brings difficulties to the use of toilets and the layout of the building.

This is where toilets with automatic lifting and draining functions and fully automatic sewage lifters are created [1].

1.The sewage lifter horizontal pipe must have a minimum downward inclination of 1:100;

2.If the sewage lifter is to be installed with a vertical drain pipe, he must be arranged before the horizontal pipe;

3.It is recommended to install a drainage plug at the bottom of the vertical pipe to ensure that the pipe is emptied during maintenance;

4.If the layout of the pipe of the sewage lifter is significantly lower than the position of the equipment, it is recommended to install an exhaust valve at the highest point of the pipe to avoid siphoning.

5.The sewage lifter drainage pipe must be connected to the main drainage equipment with standard pipe fittings;

6.Ensure that all external pipes of the sewage lifter are properly protected and sealed to avoid frost.

7.The sewage lifter pipeline needs to be independently connected to the main sewage pipe to avoid being blocked by other pipes or the phenomenon of sewage backfilling.

Install both in the back of the toilet and in the pit, and you can hide them in the cabinet.

Those who solve on the spot how many moms.

In the final analysis, the solution is that the equipment is small, easy to install, the equipment is fully automatic sewage and the fully sealed box prevents odor, which is not possessed by the traditional sewage discharge method, in fact, many people who do not understand the sewage lifting equipment, when they buy, at first glance, the sewage lifting equipment is the box, but when we use it, we find that good guys, the sewage will be automatically discharged after entering the box, and there is no need to worry about it at all.

Of course, it must be false to say that you don't have to worry about it, after all, when you buy sewage lifting equipment, you can't just buy one, or you still have to choose a reliable brand, although the sewage lifter belongs to a relatively niche brand, but you still need to consider carefully, in general, it is recommended to choose a big brand imported sewage lifting equipment, many small partners will feel that it is actually about the same, in fact, the general situation is a good brand, from the box, motor, control system and other aspects of the gap will be very large, Sometimes some inferior domestic brands may strike directly after you use them for a few days, and the key is that you can't find after-sales service, and at this time you will find that you have spent money and suffered a crime, which is not worth it.

The imported sewage lifting equipment actually pays great attention to the equipment itself, and because the technology in all aspects is relatively mature, taking Zede as an example, its sewage lifting equipment is imported from Germany, using German high-quality EMGR motors to ensure that the equipment pump starts frequently. At the same time, on the liquid level controller, it can automatically start and stop, and there is an ultra-high liquid level alarm system. In addition, the design of the external pump is also convenient for its later maintenance and system safety.

The sewage lifting device, or sewage lifter, is essentially a pump, which basically belongs to the category of centrifugal pumps, the motor rotates at high speed, and the kinetic energy is converted into potential energy to lift the sewage to a specified height.

In terms of application, sewage lifting devices are mainly used in sewage discharge scenarios that are lower than the main sewage pipes of the city, such as basement floors, including villas, and various commercial complexes, which can basically be used.

Of course, there will be places where industries like chemical and medical industries need to be used, but this will involve special requirements such as the need for acid and alkali corrosion resistance of materials, which are still very common for general household and commercial use.

There are not many people who can say that the sewage lifter is used in ** and how to use it. Although there are many brands of sewage lifters, the basic working principles are almost the same.

Working principle: When the sewage in the tank reaches a certain height, the pump starts to lift the sewage into the sewage pipe and reaches the nearby sewage pipe, which can discharge the sewage by gravity.

Sewage lifters can be divided into two types: water pumps with cutting systems and vortex pumps. The water pump with cutting system can crush ordinary viscous impurities, but cannot cut high hardness impurities, such as stone.

This model is suitable for toilet effluent lifting. The vortex pump can discharge the sewage directly without cutting impurities. In addition, the diameter of the vortex pump is relatively large, which is generally suitable for sewage lifting in places with large flow rates.

Scope of application: The applicable places of sewage lifter can be divided into two types. The sewage is lifted upwards, mostly to the upper drainage pipe, to the nearby collection well, and mostly involves the basement. The same level drainage system is also suitable for sewage lifters.

After the sewage is discharged into the lift pump, the lift pump pumps the sewage into the sewage main.

Drainage is a major focus of decoration, when draining, we need a variety of appliances to help us drain, such as floor drains, sewage lifters, let me introduce you to the sewage lifter.

1. Introduction. Sewage lifter is a kind of pressure drainage equipment, which is essentially a pump product composed of pumps, water tanks and control systems. Solve the problem that sewage with foul odor and a large number of impurities cannot be discharged to the outdoor sewer by gravity.

2. Principle. When the sewage lifter is running, the sewage enters the water tank through the inlet pipe, and when the sewage accumulates to the height of the working level of the sewage lifter, the sewage lifter starts to run. At this time, the sewage in the tank is discharged through the drain outlet at a certain speed through the pump and rises smoothly to the designated sewage pipe.

3. Classification. The applicable places of sewage lifters can be simply divided into two categories. They are upward lifting sewage discharge and horizontal sewage discharge (same layer drainage).

Upward lifting sewage is mostly to lift the sewage to the drainage pipe of the upper layer and upward to the nearby water collection well, mostly involving the basement. The sewage lifter is also suitable for the drainage system on the same floor, and the sewage is discharged into the lifting pump, and then the sewage is pumped to the main sewage pipe by the lifting pump. At the same time, the sewage lifter has a built-in one-way check valve, which can avoid the backflow of sewage.

If the villa has two basements that need to be drained, the requirements for the sewage lifter are relatively high. Because there are many water points, it is necessary to reasonably plan the installation location of the machine, and strive not to waste resources.

Where water is needed in the two-story basement, there may be several toilets, kitchens, laundry rooms, tea rooms, etc., and comprehensive drainage requires a sewage lifter with strong drainage capacity.

The intelligent sewage lifter uses an oil-cooled motor, and the parts in the motor are soaked in oil, which can not only reduce losses, but also speed up heat dissipation. The good heat dissipation effect ensures the working state of the motor, so the S1 motor working system is adopted, and the motor can be continuously drained under this working system, even if several water points are drained at the same time, the machine will continue to work in a normal state until the sewage is discharged. And such an important function of continuous drainage is not available in traditional sewage lifters.

Since the composition of sewage is different, the owner may have this thinking, should the sewage with debris and the sewage without debris need to be discharged separately? In fact, it is not needed, because all models of intelligent sewage lifters can ensure that debris can be discharged smoothly. The vortex pump has an overflow diameter of 50mm, and the cutting pump is capable of crushing debris, so what is there to worry about?

It can be found that the two-story basement is likely to use more than one sewage lifter, so it will definitely take a lot of time to adjust the equipment, and it is necessary to go to the controller of each machine to set it up. The intelligence of the intelligent sewage lifter is reflected, it can be connected to the mobile phone, so that the mobile phone has also become the control end, so the setting can be completed on the mobile phone.

In this case of large drainage, the owner must consider from many aspects to do drainage, and the choice of sewage lifter is very important, otherwise it is very troublesome to replace the equipment in the subsequent life.
