Product Description:

Product outline
1.DL series pumps are vertical, single suction, multistage,sectional and centrifugal ones and used for transporting pure water and the liquids below 85 C and with the physical and chemical natures similar to water's.
2.Vertically mounted, of a compact structure, low noise, small occupied land etc, features and mainly used for the water supply and the centralized heat supply system in cities.
3.The technical standard executed for this series pumps is:
JB/TQ809-89(Vertical multistage pump model and basic parameters),GB5659-85(Technical conditions for multistage centrifugal pumps).
4.Rotating direction of pump:CCW as viewed downward from the motor.
Pump structure
1.Model DL pump is vertically type,its suction port is located on the inlet section(lower part of pump), discharge port on the output section(upper part of pump), both are horizontally
positioned. The number of stages can be increased or decreased per the required head.There are four installation angles of 0°,90° ,180° and 270° available for selecting per different installations and uses in order to adjust the mo unting position of the discharge port (installation angle is 180° if no special note is given).
2. Major parts of the pump: inlet, middle and outlet sections,impeller, guide vane, guide vane on outlet bearing,shaft sleeve, balance drum and sleeve, conn. stand etc.
2.1 The inlet, middle and outlet sections, guide vane, guide vane on outlet section are all made of castiron and mutually form the working room of the pump.
2.2 The impeller is made of cast-iron, Liquids go in from one side along with the shaft and an axial force may exist because unequal pressures on both front and back of the impeller.Most of the force is made balanced by the balance drum while its residual is supported by the ball bearing on the upper end of the shaft.
2.3 The shaft is made of qualified carbon steel and in its middle the impeller, balance drum and shaft sleeve are mounted,which are fixed with pins and shaft sleeve nuts on the shaft to form the rotor. On one end of the shaft a lower shaft sleeve is mounted, which is fitted with the plastic bearing, and on the other the ball bearing is mounted to support the rotor and on the top of it a clutch is mounted and directly connected to the motor.
2.4 Both balance drum and sleeve form the balance device of the pump and can be replaced when worn out.
2.5 The shaft seal can not only use soft filling but also be changed with mechanical seal, when using soft filling, the shaft sleeve can be replaced when worn out and, when as the mechanical seal, the pressure water inside of the balance room is used for lubrication and cooling.
When as the filling seal, the 3/8'' flexible union on the outlet section is used through the flexible pipe to drain the water leaked from the filling body to the underground ditch to keep the place around the pump clean.
2.6 The bearing on the upper end of the pump uses molybdenum disulfide grease for lubrication

Q:What are the ways of hydraulic pumps?
There are several ways:Direct flow mode, such as external gear pump;Port plate, such as vane pump, axial piston pump, etc.;
Q:Why do we need to stop the pump?
When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.
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:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
The purpose of the steam separator is to separate the gas from the liquidWater ring type vacuum pump, water, compressed gas is discharged through the exhaust port, if not it is soda water separator is discharged, can not be separated, for the recovery of gas discharged industry is obviously impossible.Soda separator is available, the key is to see the working conditions
Q:Significance of water pump model ISO50-160
According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What are the parts of a pump? How do you classify it?I just want to know
According to the working principle can be divided into: centrifugal type and volume type centrifugal pump. By the centrifugal force of the impeller will accelerate the refrigerant, through to stay, so as to achieve the purpose of boosting; volume by changing the refrigerant in the flow volume to boost purpose.According to the media and installation conditions, water pump: centrifugal pump used: the impeller pump shaft, a curved blade on the impeller impeller outlet. The central entrance water vertically along the tangential direction of axial flow pump: high speed, large flow, low lift, mixed flow pump and centrifugal pump structure similar to that of the blade outlet angle is different, wide flow channel, close to the performance of axial flow pump displacement pump: safety valve must be opened before the start (metering pump, screw pump)
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
Vacuum pump plus form must not reach a standard atmospheric pressure vacuum, so the general can absorb 8 meters is very good, and the self suction pump itself and loss, the horizontal self-priming pump can suck on basic 4~6 meters is very good, self-priming pump. Suction lift of 30 meters is purely in the Mongolian people, does not comply with the laws of nature, obvious anti science.
Q:What is pump suction work?
In the ventilation process, pump suction is formed. The ventilation process is the whole process from opening to closing of the exhaust port. Pump Qigong refers to the cylinder gas on the piston in the forced exhaust stroke and suction stroke done by the work
Q:How should the water pump be installed?
Installation method of hydraulic pump(1) according to the technological requirements and the cavitation conditions of the pump, the installation height check and the civil engineering of the foundation are carried out.(2) prepare a series of flat washers and wedge gaskets of different thickness before installation.(3) according to the characteristics of the pump conveying medium, determine the material of the gasket at the connection and process the gasket.
Q:Why adjust the centrifugal pump outlet valve can adjust the flow?
This method can be used to regulate flow. The advantage is that it is simple and easy to use and the disadvantage is that the throttle consumes energy
