BYWT sewage lifting equipment

HYWT series equipment is a special equipment to solve the sewage discharge in the basement. It adopts the "split-type debris separator device" to avoid the clogging and entanglement of the water pump by the debris in the sewage. The sewage discharge in the sealed state is even more It has excellent protection for the environment. The equipment has the function of backwashing, which solves the problem of timely cleaning due to the sedimentation of dirt, and avoids the disadvantages encountered in the use of traditional sewage pumps.

Features


Not clogged

Adopting the unique dirt isolation and discharge technology, the pump impeller does not contact the sundries, which will not cause entanglement and blockage, which can prolong the service life of the pump.

No precipitation, no need to clear

Realize the technology of separating debris and sewage, using the pressure of the sewage pump to discharge the sewage together; it has the function of backwashing, which solves the problem of timely removal due to the sedimentation of the sewage.

Pollution-free

The equipment is fully enclosed design, no spillage, no odor, and protect the surrounding environment.

Remote monitoring (optional)

According to customer needs, the equipment can be equipped with a remote monitoring system to keep the staff on duty and to understand the operating status of the equipment intuitively.

Reduce footprint

The equipment covers a small area, is flexible to install, saves the cost of civil construction investment, and reduces costs.

Features


HYWT series equipment is an integrated integrated device that integrates sewage collection, isolation treatment, liquid level control, and enhanced discharge. It has the following characteristics:

Manual / automatic operation function:

In the manual operation state, any pump can be operated. When the water level reaches the minimum design water level, it can still automatically stop running;

In the automatic running state, when the water level reaches the set upper limit, the pump is automatically turned on to drain water. When the water level is lower than the set lower limit, the pump is automatically turned off to stop the drainage, so that the two pumps run alternately and are used as backups for each other. At the same time, the equipment can automatically switch to another sewage pump, and alarm and fault prompt at the same time.

Adopt unique debris sewage separator structure:

Adopts the debris and sewage separator structure, so that the pump does not come into contact with the entangled debris, to avoid the debris from entanglement to block the pump impeller and burn the pump motor; it has a backwash function, so that no precipitation occurs in the equipment, and no sedimentation and cleaning It can greatly save the cost of equipment operation and management and maintenance.

No stagnant water in the basement:

When the stagnant water in the local lower chamber water pond reaches a certain position, the equipment will automatically start the auxiliary pump to discharge sewage.

Control characteristics


It can realize the functions of alternate pump operation, stop pump at low liquid level, start pump at high liquid level, etc. It can also provide alarms for pump failure, phase failure and phase sequence error protection, and operation failure. The equipment can realize automatic and manual control conversion on site.

Single pump automatic operation status ---- Single pump failure automatic switch.

When the pump fails, the program will automatically transfer the equipment to the "single pump automatic operation state"; when the pump is repaired and the thermal protection is reset, the system will automatically return to the "dual pump automatic alternate operation" state.

HYWT series underground sewage equipment is equipped with liquid level float (optional for electronic liquid level sensor). The liquid level float (optional for the electronic liquid level sensor) is equipped with two water level detection points, "Liquid pump level" and "Stop liquid level", which can accurately control the alternate operation of two pumps.

Through the data line, various signals of the equipment operation status required by the user can be transmitted to the monitoring room, so that the staff on duty can stay at home, intuitively understand the equipment operation status on the monitoring screen, and prevent problems before they occur.

Use range


Sewage discharge from basement kitchen and toilet.

Sewage discharge from underground shopping malls, restaurants, baths and other service places.

Sewage discharge from subway stations, underpasses, etc.

In urban areas, small unmanned sewage pumping stations.

Large-scale pharmaceutical industry, telecommunications industry, hospitals and other large institutions sewage discharge.


Conditions of Use

Power frequency is 50HZ, three-phase AC 380V, single-phase 220V.

The debris in the sewage (including flexible debris and solid particles) must be able to flow automatically in the pipeline.

The temperature of the sewage does not exceed 40 ° C, the pH value is 4-10, and the density of the sewage is <1200Kg / m3.

The ambient humidity of the control cabinet does not exceed 80%.

Equipment operation process


Sewage containing impurities enters the water divider through the water inlet, then passes through the check valve, and then enters the separator. The separator filters the sewage and flows into the water tank. At this time, the impurities in the sewage are temporarily stored in the separator after being separated by filtration, and the sewage without impurities is temporarily stored in the water tank.

When the sewage water level in the water tank reaches the set high level, the liquid level meter works to feed back information to the control system, and the control system starts the water pump M1 to discharge the sewage. In this process, the check valve A1 uses the pressure of the sewage pump to discharge the sewage, closes the valve, and simultaneously opens the check valve B1 to discharge the pollutants temporarily stored in the separator 1 with the sewage;

While the piping system of the pump M1, the separator 1, the check valve A1 and B1 is working, the piping system of the check valve A2 continues to flow into the sewage and separates the dirt through the separator 2;

When the sewage in the water tank is discharged to the set low point, the pump M1 stops working. At this time, the check valve A1 is opened to restart receiving the incoming sewage, and the check valve B1 is closed to prevent the discharged sewage from flowing back.

When the sewage reaches the set high point position again, the liquid level gauge will feedback the detection signal to the control system, and the control system starts the pump M2 to start working. In this process, using the pressure of the water pump to discharge, the check valve A2 is closed, B2 is opened, and the dirt temporarily stored in the separator 2 is discharged together with the sewage; at the pump M2, the separator 2, the check valve A2 and B2 While the piping system is working, the check valve A1 piping system continues to flow into the sewage and separate the dirt through the separator 1;

When the sewage in the water tank is discharged to the set low point again, the pump M2 stops working. At this time, the check valve A2 is opened to restart receiving the incoming sewage, and the check valve B2 is closed to prevent the discharged sewage from flowing back.

During the drainage process, the system controls the two pumps to run alternately and repeats the above process.

※ When the liquid level float (optional electronic level sensor) detects that water has entered the equipment pit, the system will start the auxiliary pump to discharge sewage and issue an alarm at the same time.
