Vertical pipeline pump type parameter vertical pipeline pump use

Vertical pipeline pump

The pump has a vertical structure with the same diameter and diameter and is located on the same center line. It can be installed in the pipeline like a valve. It has a mounting foot to increase the stability of the pump. The shape is compact and beautiful, and the floor space is small. Low investment in construction.

Characteristic principle

ISG single-stage single-suction vertical pipeline centrifugal pump is a scientific and technical personnel. The water pump expert in the United Nations selects the domestic excellent hydraulic model, adopts the performance parameters of the IS-type centrifugal pump, and carries out ingenious combination design and manufacture on the basis of the general vertical pump. The temperature and medium are different. Based on the ISG vertical pipeline centrifugal pump, the hot water pipeline pump, high temperature pipeline pump, corrosive chemical pump and oil pump are derived. The ISG pipeline pump has high efficiency, low noise and reliable performance. Etc.

Features

The impeller is directly mounted on the extension shaft of the motor. The axial length is short and the structure is compact. The pump and motor bearings are arranged reasonably, which can effectively balance the radial and axial loads generated by the pump operation, thus ensuring stable operation and vibration noise of the pump. low.

The shaft seal adopts mechanical seal or mechanical seal combination. It adopts imported titanium alloy seal ring, medium-sized high temperature resistant mechanical seal and hard alloy material. It is wear-resistant and seal, which can effectively increase the service life of mechanical seal.

Easy installation and maintenance, no need to dismantle the pipeline system, just remove the pump joint nut to extract all the rotor components.

The series and parallel operation modes of the pump can be adopted according to the requirements of use, that is, the flow rate and the head.

The vertical and horizontal installation of the pump can be used according to the requirements of the piping arrangement.

The main purpose

ISG type pipeline centrifugal pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire boosting and equipment matching, use temperature T: ≤80 °C.

IRG (GRG) type hot water (high temperature) circulation pump is widely used in energy, metallurgy, chemical, textile, paper, and hotel hotels and other high temperature hot water pressurized circulation transmission and urban heating system circulation pump, IRG use temperature T: ≤120 ° C, GRG use temperature T: ≤ 240 ° C.

IHG type pipeline chemical pump for conveying liquids without solid particles, corrosive and viscosity similar to water, suitable for petroleum, chemical, metallurgy, electric power, paper, food, pharmaceutical and synthetic fiber sectors, using temperature T:- 20 ° C - 120 ° C.

YG type pipeline oil pump is used for conveying petroleum products such as gasoline, diesel oil and kerosene. The temperature is T: -20 °C-120 °C.

Working conditions

Suction pressure ≤1.0Mpa, or pump system maximum working pressure ≤1.6Mpa, that is, pump suction pressure + pump head ≤1.6Mpa. The pump static pressure test pressure is 2.5Mpa. Please indicate the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6Mpa, it should be separately proposed at the time of ordering, so that the over-flow part and the connecting part of the pump are made of cast steel material during manufacture.

Ambient temperature <40 ° C, relative humidity <95%.

The volume of solid particles in the medium to be transported does not exceed 0.1% by unit volume, and the particle size is <0.2 mm.
