Small submersible sewage pump how to install?

Small submersible sewage pump installation steps is what? On an article to introduce the small diving sewage pump selection precautions, today this article to introduce a small submersible sewage pump installation.

Small submersible sewage pump installation is generally divided into coupling installation and mobile installation of two installation methods. Coupled installation is through the coupler to a small submersible sewage pump connected with the pipeline, a small submersible sewage pump and outlet pipe from the convenience of the pump overhaul by lifting device can be lifted. Mobile installation refers to the pump outlet pipe directly connected to the surface through the hose, the submersible sewage pump on the bottom of the pool by gravity or hanging through the chain hanging on the lifting device. Because the mobile installation without the coupler and the bottom fixed, easy to move, overhaul with the pipeline can be lifted together. At the same time due to the reasons for the installation, it is difficult to bear a large moment, only applies to small submersible sewage pump. Therefore, the following describes the mobile installation procedure.
In general, each factory will be equipped with a small submersible pump installation instructions, the user before installation, you need to carefully read the submersible sewage pump installation instructions, the relevant installation personnel to carefully read the installation instructions, to understand the installation diagram of each Layer meaning, in order to ensure the correct installation of small submersible sewage pump. In the following, a specific installation drawing is taken as an example.
1) The lowest level
Power 11kw or more pumps can choose to install the motor cooling system to cool the pump, if not selected cooling system, is directly by the pump cooling medium. Two different cooling methods corresponding to the lowest level of different, direct cooling method requires a higher level than the cooling system with the way. In the installation conditions diagram provided by the manufacturer, use the solid triangle “▼” and the hollow triangle “▽” to distinguish, where “▼” means cooling system, “▽” means without cooling system.
2) plane openings and positioning
Submersible pump coupled installation, the plane of the hole to consider the minimum submersible pump installation size. When positioning is performed, the side of the mounting guide is the reference line. This is because the submersible sewage pump is in place by coupling with the coupling device to complete the guide rod, the guide rod position determined by the pool. Coupler base of the bolt positioning, also need to take the pool as the baseline. Finally, the most important dimensions in the drawings are: the location and size of the top planar opening, and the location and size of the embedded anchor bolts at the bottom (generally used for the post-pouring concrete design). The top of the guide rod fixed expansion bolts are usually used to complete the way.
Also note that the small submersible sewage pump though small, but also to install the relevant safety equipment, such as float switches, humidity sensors.
Above is the installation of small submersible sewage pump need to pay attention to the relevant matters, if you do not know can contact us, professional engineers will provide you with one-on-one service.

Sewage pump use and features

Sewage pump is a kind of pump and motor connected to the same time, submerged into the work of the pump products, compared with the general horizontal pump or vertical sewage pump, sewage pump compact structure, small footprint, vibration and noise, motor Low temperature, no pollution to the environment.
The use of sewage pumps:
① Enterprise unit wastewater discharge.
② urban sewage treatment plant emissions system.
③ subway, basement, air defense system drainage station.
④ hospitals, hotels, high-rise building sewage discharge.
⑤ residential sewage drainage station.
⑥ municipal engineering, construction sites in the dilute slurry emissions.
⑦ water supply plant water supply device.
⑧ farm sewage and rural farmland irrigation.
⑨ exploration of mine and water treatment equipment.
⑩ instead of shoulder to pick people Tam, suction river mud.
Sewage pump features:
① using a unique single-blade or double-blade impeller structure, greatly improving the dirt through capacity, can effectively pass the pump diameter of 5 times the diameter of fiber material and pump diameter of about 50% of the solid particles.
② mechanical seal with a new type of hard corrosion-resistant tungsten carbide material, while the seal improved to double-face seal, so that long-term operation in the oil chamber, the pump can run safely for more than 8000 hours.
③ The overall structure is compact, small size, low noise, energy-saving effect is remarkable, easy maintenance, no need to build pump house, diving into the water to work, greatly reducing project cost.
④ The pump sealed oil chamber is equipped with high-precision anti-jamming leakage detection sensor, and the stator winding embedded in the thermal element, the absolute protection of the pump motor.
⑤ According to the needs of users with automatic safety control cabinet, the pump leakage, leakage, overload and over-temperature, such as absolute protection, improve product safety and reliability.
⑥ Float switch can be changed according to the required liquid, automatic control of pump start and stop, without special care, the use of extremely convenient. ⑦ According to user needs with dual-rail automatic coupling installation system, it gives the installation and maintenance of great convenience, people do not have to enter the sewage pits.
⑧ can be used within the whole head, and ensure that the motor is not overloaded.
⑨ There are two different installation methods, fixed automatic coupling installation system, mobile free installation system.
Sewage pump According to the different sewage, sewage pump can be divided into self-priming sewage pump, liquid sewage pump, with knife-type sewage pump and automatic mixing sewage pump. Can also be divided into:
① vertical sewage pump
② submersible sewage pump
③ self-priming sewage pump
④ automatic mixing sewage pump

How to protect the surface of the water pump?

As is known to all, submersible pump is a kind of general machinery and equipment, its application in various fields of national economy is very extensive, the used water pump knows, use a long time, the water pump of the pump casing and pump wheel surface due to rust, corrosion, abrasion and cavitation erosion damage and become bumpy, friction coefficient increases gradually, so as to cause a decline in the efficiency of pump, power consumption increases, will shorten the service life of pump.
Encountered such a situation how to deal with? At present, the corrosion resistant ability of the pump, reduce the friction coefficient, and increase the service life of the pump and energy saving, can make use of organic polymer materials to protect the surface of pump flow channel to solve this problem.

WQ submersible sewage pump use advantages

WQ submersible sewage pump has been more and more attention from the original simply used to transport water to transport a variety of domestic sewage, industrial wastewater, construction site drainage, liquid feed and so on. In the municipal engineering, industry, hospitals, construction, hotels, water conservancy construction and other industries play a very important role. Compared with the general horizontal pump or vertical sewage pump, submersible sewage pump obviously has the following advantages:
1. Compact structure, small footprint. The submersible sewage pump can be directly installed in the sewage tank because it can work in the submerged water, so it is unnecessary to build a special pumping station to install the pump and machine, which can save a lot of land and capital cost.
2. Installation and maintenance convenience. Small submersible sewage pump can be installed free, large submersible sewage pump is generally equipped with automatic coupling device can be automatically installed, installation and maintenance is very convenient.
3. Continuous operation for a long time. Submersible sewage pump As the pump and motor coaxial, shaft short, light weight of the rotating parts, so bear the bearing radial load is relatively small, life expectancy is much longer than the average pump.
4. There is no cavitation damage and irrigation water and other issues. In particular, the latter point to the operator to bring a great deal of convenience.
5. Vibration and noise, the motor temperature is low, no pollution to the environment.
