sump drain pump installation practice

Installation method: 1.If the geographical environment permits, the pump should be as close to the water source as possible to reduce the length of the suction pipe.

The foundation of the pump installation place should be firm, and a special foundation should be built for the fixed pumping station.

2.The water inlet pipeline should be sealed and reliable, and must have special support, and should not be hoisted on the pump. The water inlet pipe equipped with the foot valve should be installed perpendicular to the axis of the foot valve and the horizontal plane as far as possible, and the axis should be installed with the horizontal plane.

The angle shall not be less than 45°. When the water source is a channel, the bottom valve should be more than one meter higher than the bottom of the water, and the net should be added to prevent debris from entering the pump.

3.The base of the machine and pump should be horizontal, and the connection with the foundation should be firm. When the belt of the machine and pump is driven, the tight edge of the belt is below, so that the transmission efficiency is high, and the steering of the impeller of the pump should be indicated with the arrow.

Send; When the coupling is used, the machine and pump must be coaxial.

4.The installation position of the water pump should meet the requirements of the allowable vacuum suction height, and the foundation must be horizontal and stable to ensure that the rotation direction of the power machinery is consistent with the rotation direction of the water pump.

5.If there are multiple units in the same machine room, there should be a distance of more than 800mm between the units and between the units and the walls.

6.The suction pipe of the water pump must be well sealed, and the elbow and gate valve should be minimized, the air should be exhausted when filling the water diversion, and the air should not accumulate in the pipe during operation, and the suction pipe should be slightly inclined upward and pumped.

The inlet should have a certain depth of inundation.

In the process of decoration of the basement, if there is a design bathroom, kitchen or water bar, then we should know more or less about the basement drainage, which is to solve the drainage of the basement through the sewage lifting pump, because the closed box of the sewage lifting pump can isolate the odor, which also avoids the breeding of mosquitoes, and the drainage of the basement uses the sewage lifting pump, which is simpler and more convenient, and more secure, because the installation of the sewage lifting pump is completed as long as the water and electricity are completed in the decoration process. As long as the various pipes are connected, the installation of the sewage lifting pump can be completed, eliminating excessive engineering quantity, and the sewage lifting pump will automatically start working as long as it is energized, and the sewage in the water tank will automatically start drainage when it reaches a certain height, without other operations.

So, what should be paid attention to when installing a sewage lift pump?

First of all, before the installation, it is necessary to communicate the laying of the pipeline and the power reserve of the sewage lifting pump before the installation of the water electrician, so that in the decoration process of the water and electricity, this is completed, which is convenient for the installation of the sewage lifting pump and the connection of the pipeline in the later stage, and it is an important step to plan and reserve a good position in advance.

Secondly, when installing the sewage lifting pump, after we complete the post-installation test, we should pay attention to the protection of the sewer pipe if the overall decoration of the home has not been completed, so as to prevent the decoration of large pieces of debris from falling into the water tank of the sewage lifting pump, causing some unnecessary trouble.

Finally, when we install the sewage lift pump, the drain pipe of the sewage lift pump should be higher than the main sewage pipe access. And try to get as close as possible to the rear of the main sewage pipeline, to prevent the sewage in the main sewage pipeline from backing up into the pipeline of the sewage lifting pump, because the sewage lifting pump has its own check valve, which will not cause the sewage to flow back into the water tank.

Once we have a good idea of these questions, we will be more comfortable using them later.

1.Before installation, the debris and sludge at the bottom of the sump should be cleaned up before installation, especially the gravel and concrete fragments, which are easy to block the impeller of the pump and cause motor damage. Secondly, the position of placing the pump at the bottom of the pit should be set up with a cement platform about 10 cm high and an area slightly larger than the base of the pump, which can effectively prevent sediment and debris.

2.Installation of pipelines Under normal circumstances, at least two pumps should be installed in each sump, one for use and one for backup, so as to ensure the normal drainage in the case of one of them failing; In addition, each pump should be equipped with a check valve and a valve, and the position of the check valve should be as close as possible to the outlet of the pump, so as to reduce the amount of water returned and convenient.

3.Power wiring Generally, the sewage pump manufacturer is only responsible for the wiring between the electric control cabinet and the sewage pump, and the power supply line of the electric control cabinet is threaded by the buyer himself. Here, we must pay attention to the phase sequence of the power supply incoming line, and before connecting to the electric control cabinet, it must be measured and determined with a multimeter to ensure that the live wire and the neutral line will not be connected wrong.

Installation of the float Although the installation of the float is a very easy job, there are a few points that must be noted: first of all, pay attention to the float.

1. The pump installation of the sump submersible sewage pump drainage, the installation of the drainage pump, the installation of the control box, the installation of the liquid level, the installation of electrical piping, the installation of the valve flange, and the installation of the drainage pipeline.

2. The sewage pump installation project of the sump sewage pump does not have a single-stage centrifugal or impurity pump. The difference between a centrifugal pump and a centrifugal impurity pump is that the medium being conveyed is different. For example, centrifugal pumps are generally used in water supply pipelines, HVAC pipelines, and fire pipelines, and impurity pumps are generally used in the process of paper mills.

The sump should be equipped with centrifugal impurity pumps, including pump installation, float level gauge installation, valves, soft joints, pressure gauge accessories installation, pipeline pipe, electrical piping and control box installation, etc.

Installation steps of the water pump:

1. Preparation before installation, horn, etc.

2. The installation height of the sewage pump is determined, and the suction pipe is required to have strict sealing, and no air or water leakage can be allowed.

3. Pump positioning and alignment.

4. Pump elevation adjustment and initial leveling.

5. Pump anchor bolt grouting and * horn placement.

6. Find the levelness of the pump and the alignment of the coupling.

When excavating the foundation pit or trench, set up a collection well at the bottom of the pit, and excavate the drainage ditch along the periphery of the bottom of the pit or **, so that the water can be used in gravity as a sump drainage pump A sump drainage pump When excavating the foundation pit or trench with the sump drainage pump, a collection well is set at the bottom of the pit, and the drainage ditch is excavated along the periphery of the bottom of the pit or **, so that the water flows into the catchment well under the action of gravity, and then pumped out of the pit with a water pump. The surrounding drainage ditches and collection wells should generally be set up outside the foundation range, and when the upstream of the groundwater flow and the foundation pit area are large, blind ditch drainage can be set up within the foundation pit range. According to the amount of groundwater, the shape of the foundation pit and the capacity of the pump, the water collection well is set up every 20 40m.

A small pit should be dug in the place where the water is stagnant, so that the water can be concentrated in the pit faster, so that the drainage pump can be pumped away quickly, and when placing the drainage pump, do not let the drainage pump be blocked by other things, so as not to affect the pumping.

Make sure the gutter is clear and free of blades and other debris, and in addition, water can easily flow through the gutter and into the drain pipe. [1]

Make sure that the downspout can get the rainwater far enough away from the house and that it doesn't flow back. The downspout should be arranged at a distance of meters from the house.

The soil on the surrounding slopes is at least a meter or two away from the house. If there is a pit around the house, it can cause water to accumulate and make the water seep, which can cause problems in the basement. Deal with these issues before buying a dewatering pump.

Although the installation of the float is a very easy job, there are a few points that must be noted: first of all, we should pay attention to the position of the float, most of the current sumps are installed with 2-3 floats, the pump is stopped at low water level, a pump is started at high water level, and two pumps at the same time at ultra-high water level, and the installation principle of float position is to ensure that the sewage in the sump is to be ensured.

First, make embedded parts (pipe clamps, pump seats, guide rails, power cords......After the waterproof and protective layer is done, the pump is in place, and then the pump drain pipe and valve and other accessories are installed, and then the pump is test-run.
