Pumping equipment is used today in many areas of human activity. The Irtysh pump is no exception. It is presented for sale in various versions, among others, those that are indicated by the letters PF should be highlighted. This is a series of submersible electric pumps, the main purpose of which is the pumping of domestic waste water, industrial sewage that contains large fibrous substances. The operation of this equipment is carried out after complete immersion in wastewater. The design is unique, therefore it is able to function even in difficult conditions, while control by staff is not required.
Areas of use
The pump "Irtysh PF" is a centrifugal equipment, which has found its distribution in housing and communal services, industrial construction, the civilian area, where the pumping of drains is necessary. These devices pump media that must meet certain parameters. For example, the temperature of sewage should not rise above +50 ° C.
Some specifications
It is important to take into account the hydrogen index, it is in the range from 6 to 9 pH. As for the density, it should not seem more than 1100 kg / m 3 . Non-abrasive particles may be contained in the composition of the medium in a volume of up to 2%. Non-abrasive particles can have sizes from 25 to 70 mm. The Irtysh pump pumps sewage in which the volume content of abrasive particles should not exceed 1%. Their size should not be more than 5 mm. Particles on microhardness should correspond to an indicator of 9000 MPa.
Design Features Reviews
The fecal pumps, which are designated by the letters PF, are monoblock vertical centrifugal units operating due to the built-in sealed electric motor. Consumers like that it has a special design and is located above the pump part.
Its cooling is carried out by the pumped liquid. A centrifugal closed impeller is located inside the pump part, it can have one or more channels. The design, according to consumers, is quite simple, it provides for the presence of:
- spiral casing;
- vortex impeller;
- oil chamber;
- closed case.
Customers especially emphasize that the electric motor has moisture protection, which is guaranteed by a fixed seal, a moisture sensor and an oil chamber. Thermal sensors provide connection to the motor if it overheats. According to consumers, this significantly increases the life of the device. The Irtysh pump is supplemented by a control panel and float-type switches. This can be called a significant advantage.
Key Features: Decoding Labeling
The Irtysh pump, the technical characteristics of which are presented in the article, is equipment, before starting which it is necessary to check whether the voltage in the network matches the voltage of the equipment. When operating these devices, it is necessary to orient their case vertically.
A sling is attached to the package, it can be used only for transporting the unit, but not for its installation. For the successful operation of the equipment during its acquisition, it is important to familiarize yourself not only with the purpose, but also with the main technical characteristics. They are usually spelled out on the label.
For example, the pump "Irtysh PF1 65/160. 132-3 / 2-026 "is a submersible type equipment without forced cooling of the engine. A device for wastewater is intended, which is determined by the letter F. The first numbers indicate the nominal diameter of the discharge pipe, which in this case is 65 mm.
As for the number 160, it indicates the nominal diameter of the impeller, while 132 is the actual diameter of the impeller. The last figures indicate how to protect the engine. The pump "Irtysh PF1 65 / 160.132-3 / 2-026", the overall dimensions of which, as is now clear, can be found in the passport, is an equipment with moisture and thermal protection.
Reviews about the device and its principle of operation
Electric pumps of the Irtysh brand are monoblock units, which usually have a vertical design. Consumers like that a special order can be purchased a horizontal version of the equipment. It consists of a control panel, which allows the device to work in manual and automatic mode. The latter option is only possible with a float switch.
The design has a single-stage centrifugal pump, which has a spiral casing. If you are interested in the Irtysh pump, the technical characteristics of PF equipment should definitely be considered. They are discussed in the article. For example, it is worth noting that for devices with a mechanical seal, there must be a coolant in the cavity of the mechanical seal.
Consumers are advised to pay attention to the principle of operation. It consists in the rotation of the impeller using kinetic energy, which is transmitted to the fluid by centrifugal force. It is sent to the spiral chamber of the housing, where the conversion of kinetic energy to pressure energy occurs.
Buyers emphasize that the impeller has a special geometric shape, which provides impressive hydraulic parameters and allows you to pump media that contain solid particles, dirt, and also elements in suspension. In this case, there is no danger of clogging, because a free vortex impeller can pump even long-fiber elements.
Conclusion
Irtysh pumps have an effective moisture protection system; it consists of a set of seals, an oil chamber, a moisture sensor, a set of stationary seals and bearings. In addition, the design is equipped with a thermal protection system, which includes thermal sensors installed in the stator. Due to this, the electric motor switches off automatically in case of overheating.
