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:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
- Water ring vacuum pump is divided into many types, different sizes, different types, so water is different. As for how much water the no fixed amount, but to ensure that the water temperature is in 25 degrees, not more than 35 degrees can be.
- Q:Does the reservoir water heater press the booster pump (high marks)?
- 60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.
- Q:Is the vacuum pump air compressor?
- A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.
- Q:What is the lift of diaphragm pump?
- Diaphragm pump lift is different from the centrifugal pump, refers to the diaphragm pump can raise the height of water, the unit is meters water column. Lift depends on the size of the outlet pressure, the pressure per kilogram is equivalent to 10 meters height
- Q:What is the difference between an air pump and a water pump?
- The air pump (Q. B ng air pump), namely "air pump", a device for removing air or add air from the enclosed space from a closed space. The air pump is mainly divided into an electric air pump and a manual air pump. Electric air pump. An electric pump powered by electricity; produces air pressure by constantly compressing the air through electricity. Mainly used in pneumatic rubber, car inflatable, etc..
- Q:What are the main performance parameters of hydraulic pumps?
- Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
- Q:What is the name of the day pump and ground pump? Specific introduction
- Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.
- Q:What does "efficiency" mean in a water pump catalog?
- Pump efficiency: the ratio of the effective power and the pump shaft power
- Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?
- The pump is in operation, if the over-current part of the local area (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began in the area, produce a lot of steam, forming bubbles, when the liquid contains a lot of bubbles forward by high pressure impeller zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst at the same time, the liquid particle filled hole at a high speed, this moment has a very strong effect of water hammer, and with a high impact frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be.The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.
- Q:Water pump can not be pumped out, how to maintain water?
- Severe vibration of water pumpIt is possible that the rotor is unbalanced, or the coupling is not good, the bearing is worn and bent, and some parts may be loosened and broken. They can be adjusted, repaired, strengthened or replaced separately.
