Description

DG type pump is horizontal multistage centrifugal pump,which is used to transport clean water with temperature less than 160℃,and also insoluble solid impurity 0.25%,and liquid such as water-soluble solid impurity 5% and other medium similar to water.

Application Area

It is mainly used in light textile industry comprehensive utilization and also sub-high pressure boiler water supply in small-scale thermal power plant.

Performance Range

Inlet diameter: 50-150 mm

Capacity:6-155m3/h

Head:50-960m

Speed:2980r/min

Matched power: 4-450kW

Structural Characteristics

The pump is single casing,single suction,multistage sectional centrifugal pump structure.The inlet%outlet of pump is vertical.(Please refer to structure chart).Detailed structure is as follows:

1、Stator part

It is mainly contained by some parts such as forepart,back part,middle part,guide vane bearing support&balance room,etc,which are all combined by tie bolt and nut.

2、Rotor part

Round nut has been tensed by impeller,impeller space sleeve,balance spacer sleeve,balance disk&shaft sleeve.Moreover,it has been fixed on the main shaft,which adopts flat key so as to avoid rotate.In doing so,the whole rotor supports on the both sides of bearing,consequently,rotor connected with motor directly by elastic pin coupling.

Gear gasket has been installed between impeller and balancing guard sleeve in order to compensate expansion,such part should be replaced during maintenance.

3、Balance organization

This pump adopts balance disk hydraulic balancing device,it is made up of balance ring,balance disk,balance sleeve and balance guard sleeve.

Balance leakage water will return to front-section suction vortex chamber.

Q:Excuse me, what is the water pump from the lotus root?
The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection
Q:What are the functions of a disposable infusion pump?
This is a very professional question, ha!I only know disposable infusion pumpsAttached: intelligent medical infusion pump and its application
Q:What kind of motor does the hydraulic pump need?
The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:
Q:How many kinds of pumps are available and the operating principles of various pumps?
There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..
Q:How to install, operate and maintain the pipeline booster pump?
Should be "People's Republic of China network security law" requirements, since June 1, 2017, the use of Internet services to carry out real name authentication account. In order to ensure your Baidu account can be used normally, please check the account number as soon as possible. Thank you for your understanding and support.How to install, operate and maintain the pipeline booster pump?Brother Yao s Gc76 2547 | browseRecommended for 2016-12-01 23:52:54 best answerThe installation of booster pump must be installed horizontally or vertically according to the installation method. The direction of flow shall be consistent with the arrow on the pump body, and installed as far away from the water level as possible. A valve shall be installed on the pump inlet line for ease of use and maintenance. When the impeller is the aspiration level below the pump on the pump shaft end or around the pump should be installed check valve, the outlet is connected with 13 links for water use, at first use to pump should be filled with water, and tighten the screw plug. The pipe connection should be tight, especially the water inlet pipe can not leak, otherwise it will reduce the pump head or not pumping water. The pump cavity is not water, not a long time running, so as not to damage the seal
Q:Water pump outlet valve sequence
Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.
Q:Fire hydrant pump button, under what circumstances do not need to install?
The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
Q:I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?
15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
Q:What are the characteristics of a vertical multistage centrifugal pump?
Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.
Q:What are the important parameters of the pump?
The head is the unit weight of liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid used, referred to as meters.Speed nThe speed is the number of revolutions per unit time of the pump shaft. It is indicated by the symbol n. The unit is r/min.Cavitation allowance NPSHCavitation margin, also called net positive suction head, is the main parameter to indicate the cavitation performance. The cavitation margin has been expressed by delta H at homePower and efficiencyThe power of water pump usually refers to the input power, that is, the power transferred by the prime mover to the pump shaft, so it is also called shaft power. It is expressed by P;The effective power of the pump, also known as the output power, is expressed in Pe. It is the effective energy obtained by pumping the liquid out of the pump in unit time
