How to consider the preliminary design of integrated prefabricated lifting pump station

What is an integrated prefabricated pump station? What is the function of integrated prefabricated pump station? What should be considered in advance before designing the integrated prefabricated pump station?

The integrated prefabricated pump station is the power source to solve the problems of drainage and irrigation, water supply and water resource allocation under the condition of no artesian flow; the box, pipeline, valve and accessories are made of 304 sanitary stainless steel; the environmental protection and corrosion resistance are strong, and the service life is up to 20 years; the construction of the integrated lifting pump station will effectively relieve the drainage pressure of the main road and improve the drainage efficiency of the underground pipeline.

The daily domestic sewage can be lifted to the water collecting tank, and the sewage below the horizontal surface or the rainwater in the basement can be lifted to the drainage pipe network for discharge; the integrated lifting pump station

It can be applied to the sewage discharge in remote areas. The conventional discharge system is expensive, and the ground elevation is difficult to overcome, so it can't discharge by itself, or it can only be used in places where small caliber pipes can be laid;

For expressway service area, large construction site, municipal construction reconstruction and other sewage discharge;

Improve the discharge of sewage from hospitals and hotels;

Other fields: sewage discharge from slaughterhouses, food processing plants, paper mills, agriculture and other fields.

The integrated prefabricated pump station can isolate the sundries in the sewage in the grid, so that the sundries will not contact the pump impeller directly, so that the sewage pump is in a good operating environment; the construction of the integrated prefabricated pump station will effectively relieve the drainage pressure of the main road and improve the drainage efficiency of the underground pipeline;

The construction of the integrated prefabricated pump station will effectively relieve the drainage pressure of the main road and improve the drainage efficiency of the underground pipeline; the exquisite sewage pump and controller can be installed in a small cylinder without affecting the operation effect;, The self-developed man-machine interface of the integrated pump station is easy to learn, intuitive operation data, small floor area, low operation cost, and no special person is required for on-site management; the whole process of supervision and installation is to ensure that the installation of the integrated pump station is correct and all pipelines and electrical connections are in place;,

Before the design of integrated prefabricated lifting pump station, the following items should be considered:

1. Space saving: the water pump and pump chamber are placed in the water tank and fixed on the special module of the integrated lifting pump station. Generally, only 0.5-1.5m water tank is used.

2. Easy to move and disassemble, long service life: due to the use of fabricated stainless steel material, the previous welding method has been changed, and screw assembly is adopted, which has strong applicability and convenient installation, without special equipment.

3. Convenient evacuation: due to the use of a new type of submersible fire pump, it is directly submerged in the water, without special exhaust air, as long as the water tank level is within the specified level, it can directly enter the state of fire water supply.

4. Frost free: the fire pump is submerged in the depth of the integrated lifting pump station, which will not be burnt due to freezing in winter.

5. Low noise: equipped with water immersion motor and water pump, greatly reducing the running noise.

6. Reliability: the water immersed motor of the integrated lifting pump station will not burn out the motor or corrode the motor bearing due to rain or ambient temperature.

What parameters should be taken into account in the design of integral prefabricated lifting pump station?

1. The inflow flow Q (m3 / h) of the integrated prefabricated lifting pump station, and the coefficient of change at large flow;

2. The number and head of water pumps required, one for use and one for standby or two for use and one for standby;

3. Outdoor ground elevation H0 (m), or relative elevation ± 0.00 (m)

4. The diameter DN of the external connecting pipe of the inlet pipe of the integrated lifting pump station and the bid winning height H1 (m);

5. The external diameter DN of the outlet pipe of the integrated lifting pump station and the bid winning height H2 (m);

6. Internal pipeline material: stainless steel SUS304 or hot-dip galvanized pipe fittings;

7. Integrated prefabricated liquid level sensor, pressure sensor, floating ball, ultrasonic liquid level sensor of lifting pump station;

8. Control system, automatic level control, manual control, remote control;

9. Type of grill selected, basket grill or crushing grill;
