Description

 

  • The traditional concept of water pump design is that hydraulic design is higher than structural design, in order to improve the efficiency of water pump by 1%, regardless of the cost of products increased by 10%. In the traditional design concept, design and structure of hydraulic blade oblique flow impeller with space become the main design method of deep well pump, because of the high efficiency of the pump of this type, flow and head is also consistent with the national standard value. However, this kind of deep well centrifugal pump has the largest axial size, the most difficult to manufacture blades, the highest production costs, so its comprehensive economic benefits are very low.
  • If the change of design concept, the design of the structure is placed in front of the hydraulic design, according to the hydraulic design method to determine the structural conditions, to reduce production costs and improve reliability in the first place, to meet the needs of hydraulic design, structure design, for deep well pump, requires the use of vertical structure, which is a kind of impeller maximum diameter design method and structure form of anti missile vane supporting shell, this structure can achieve the maximum diameter of the impeller, the shortest length of diversion shell structure requirements.
  • In this form of structure, the method of hydraulic design can be expected to achieve maximum economic benefits.

 

 

Centrifugal pump (slurry pump) operation should pay attention to the following points:

 

  1. Prohibition of waterless operation, do not adjust the suction population to reduce displacement, prohibited under low flow operation;
  2. Monitor the operation process, completely prevent the packing box from leaking and replace the stuffing box with new packing;
  3. Ensure that the mechanical seal is adequately flushed and water cooled bearings prohibit the use of excessive water flow;
  4. Don't use too much lubricant;
  5. Check according to the recommended cycle. Set up operation records including running hours, filling adjustment and replacement, adding lubricant and other maintenance measures and time. The centrifugal pump suction and discharge pressure, flow rate, transmission power, the temperature of the wash and bearing, and vibration should be recorded regularly.​

Description

 

  • The running practice of the water pump shows that the existing pump varieties can not be fully adapted to the operation needs of all kinds of situations. Therefore, in use will appear in the performance of the pump and the actual need not adapt to the situation, this will make the pump in the off design conditions of operation, accelerate the power consumption and damage the pump, but also reduces the stability and reliability of pump.
  • Water pump efficiency is a technical and economic index to measure the efficiency of water pump. It is the ratio of the effective power of the pump (that is, the output power of the pump) and the power of the pump shaft (that is, the input power of the pump). Water pump efficiency is generally 65% ~ 90%, large pumps can reach more than 90%.
  • The efficiency of water pump depends to a great extent on the use of the pump. If the maintenance and use are not proper, even if the pump is efficient, it can not achieve the purpose of high efficiency, low consumption and economic operation. Therefore, in the actual operation of the pump, we should try to improve the efficiency of the pump, as far as possible to reduce the energy in the water pump transmission process, there are various energy losses.

 

 

General method for improving pump efficiency:


1. improve the efficiency of the pump itself


1) reduce water loss, design efficient impeller;
2) reduce mechanical losses and friction losses;
3) reduce leakage;


2. improve the efficiency of the pump

 

Improve piping system to reduce resistance. The length of the pipeline should be as short as possible and keep straight, reduce the flow rate to reduce the head loss along the way; to reduce the number of gate valve, valve, elbow and other parts, in order to reduce the local head loss.
To reduce the surplus water pressure of the water pump, meet the demand of the outlet water pressure of the piping system. Try to make the pump work at the best possible point of the pump and avoid working under large or small flow.

Horizontal Single Suction Centrifugal Pump For Delivery Water / Chemical Liquid

  • Horizontal Single Suction Centrifugal Pump For Delivery Water / Chemical Liquid
Product Details:

Small boiler water supply Electric Centrifugal Pump / DG single suction centrifugal pump

 

 

Uses:

 

The series of pumps horizontal single-suction multi-stage centrifugal pump, for the delivery of water or physical and chemical properties similar to the liquid water for medium and low-pressure boiler Or secondary high-pressure boiler feed water, but also for factory or urban high-pressure water supply and drainage. The conveying medium temperature is -20 ℃ ~ 150 ℃, the inlet allowable pressure is less than 0.6MPa.

 

 

【Product Features】

 

DG type pump inlet and outlet are vertical up, by tightening the bolts of the pump into the water, the middle, the water section, the bearing body and other pump parts connected into one, according to the pump head selection pump series.

The series of open pump rotor part of the shaft and installed by the shaft on the impeller, bushings, balance plate and other components, including the number of impellers according to the pump series. The shaft parts are fastened to the shaft by means of the flat key and the shaft nut. The entire rotor is supported by both ends of the rolling bearing or sliding bearing, the bearing is different depending on the model, do not bear the axial force, the axial force balance by the balance plate, the pump in the run to allow the rotor in the pump shell axial swimming, Using radial ball bearings. Rolling bearings lubricated with grease, sliding bearings with thin oil lubrication, and oil ring for self-lubricating, circulating water cooling.

The sealing surface between the inlet section, the middle section and the water outlet of the pump is sealed with molybdenum disulfide grease, and the sealing part and the guide vane cover are sealed between the rotor part and the fixed part.
