Product overview
Fourth generation KQL, KQW series single-stage single-suction centrifugal pump, is my company USES the best hydraulic model, and according to the working condition of all types of users under different conditions of use carefully designed. This series of products, compact structure, reasonable, stable and reliable operation; Configuration of special machine sealing structure, improve the operating environment, extend the service life; High efficiency and energy saving, low operating cost, saving management costs; Cover an area of an area small, save construction investment, favored by the market.
Application field
The central heating system of circulating water; Refrigeration, cooling circulating water of air conditioning system
Water treatment, sanitary water; Indoor living water supply, domestic hot water system
Water supply, water irrigation system; Flushing system with water
Product features
1, the pump and motor directly connected, pump shaft completely concentric, small vibration noise is low; Special structural configuration of bearing, impeller cantilever short, operation is stable and reliable
2, the use of forced circulation should not be restricted to the special structure of configuration of mechanical seal, improve its running environment, prolong service life
3, advanced pump chamber and the impeller design, make the pump has the superiority of hydraulic characteristics, ensure the pump efficiency and energy saving, low running cost, cut down the cost of operation management by 50% to 70%
4, unique installation structure greatly narrowed the pump cover an area of an area small, save construction investment from 40% to 60%
5, stainless steel shaft, never rust, guarantee the mating part tear open outfit is simple, reliable mechanical seal bellows seal, maintenance-free, easy to maintain。
The working conditions
Traffic: 1.8 ~ 2000m3 / h head: 127 m or less
Transfer rate: 2900 r/min, 1480 r/min, 980 r/min
Medium temperature: - 10 ~ 80 ℃ ambient temperature: maximum + 40 ℃
Maximum working pressure (pressure) :
125 diameter (2 extreme speed) and below 125 diameter: 1.6 Mpa
125 diameter (4 pole speed) and 150 ~ 200 diameter: 1.2 Mpa
250 caliber and more than 250 diameter: 1.0 Mpa
- Q: Why does the centrifugal pump close the pressure to start?
- Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
- Q: What are the general water pump failure, how to repair?
- Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.
- Q: How many millimeters is the diameter of the water outlet of the four inch pump?
- Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.
- Q: What should I pay attention to when buying a pump?
- There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.
- Q: How many kinds of pumps are available and the operating principles of various pumps?
- There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;
- Q: What are the application areas of pumps?
- Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the liquid is transported up to -200 DEG C, up to 800 DEG C. Pumps carry a wide variety of fluids, such as water (clean water, sewage, etc.), oils, acid and alkaline solutions, suspensions, and liquid metals.In the chemical and oil sector production, raw materials, semi-finished products and finished products are mostly liquid, and semi-finished and finished products to raw materials, need to go through a complex process, to pump and provide transportation of liquid chemical reaction of the pressure and flow in the process, in addition, the device also used in many pumps to adjust the temperature.In agricultural production, the pump is the main irrigation and drainage machinery. Rural areas in our country are vast and vast, and a large number of pumps are needed every year in rural areas. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most widely used equipment in the mining and metallurgical industries. The mine needs pumping and drainage. In the process of ore dressing, smelting and rolling, the pump needs water to supply water first.
- Q: What is pump suction work?
- Pump is mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.
- Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..
- 7., master the knowledge of concrete mix ratio, strictly forbid to add water to the pump at will.8., concrete mixing and workability, gravel diameter is too large, effectively refuse to pump.9. when the delivery pump fails, it can analyze the cause and quickly eliminate the trouble.10. pump complete, you must clean the pump body and pressure pipe residual.11. complete other temporary work assigned by the leader.
- Q: Hydraulic pump displacement refers to the pump shaft what?
- Just as you carry a spoon to the water. How much water can you pump at once (every turn)? That's the displacement.
- Q: Does the control cabinet of the fire control pump need to be related to the fire control room?
- Normal words are needed, but when you check and check, has anyone checked?
