Structural Characteristics of Single Stage Double Suction Split Casing Pump

1, Compact structure
Nice appearance, good stability and easy installation.
2, Operate steadily
The double suction impeller which is optimum and designed by computer, and has a large inlet flowing area. The clapboard is set at packing box of inlet flow passage, it makes no vortex at inlet of pump. It adopts resin sand moulding and high quality cast technology to make the inner surface of pump casing and the surface of impeller smoother than before. Through above measures, we make pump operate with no vortex, operate smoother and have remarkable erosion-resistant ability and high efficiency.
3, Bearing
Excellent bearing is used to assure the steady operation, low noise, long service life. Grease lubrication and closed structure is used. If thin oil lubrication structure is needed, a constant level oil cup shall be equipped.
4, Shaft seal
Mechanical seal or packing seal shall be used. These two kinds of seal are all installed in the removable packing box, which is convenient to assembly and maintenance. The packing gland of pump is removable and open, which assures enough room for maintenance and repair.
5, Impeller
The latest technology is adopted as well as the best hydraulic model, which makes the double suction impeller can balance the axial force automatically.
6, Shaft
Shaft is completely sealed without contacting the medium or corrosion. The length of the shaft is shortened compared with that of S, SH type pumps, and it is hard with no vibration. A replaceable shaft sleeve is installed on the shaft. There is no thread on the shaft, and o-ring structure is adopted to assure shaft and bearing do not contact the medium to improve the service life. It is easy to assemble without adjustment. Pump rotor part shall be installed with elastic prestressing force, which makes the installation and disassembly much easier and more convenient.
7, Casing
For the pump of high head, double split casing passage is adopted, which counteracts most of the radial force and prolongs the life of bearing on two sides.
According to the different mediums and using requirements, main parts of the pump can adopt various materials

 

FAQ

Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

Q: How can I get trained on CNBM products?

A: Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

The pump head is the height or length of the distance from the pump to the outlet
Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
Filter pump for oxygen spray. If the filter pump water flow, you can throw oxygen flowers, you can not use. With that pipe, it's loud and kind of
Q:The role of water replenishing pump in circulating system
The water loss, if the level is too much loss, circulation system will not have a negative effect, the other, needs to pay for water pump system, are generally set up a level, when the automatic water level below this post.
Q:What is the reason that the water supply of pump is getting smaller?
What kind of pump is it, home pump or factory pump? Single stage impeller or multistage impeller? Vertical or horizontal? Is it single suction or double suction? Different structure of the day pump has different causes of failure. But in general, there are several aspects: 1., the water inlet is small, the inlet pipe is blocked; 2., the blade is worn or broken; 3., the motor speed drops; 4., sealing serious leakage; 5., cavitation phenomenon.
Q:Pump adapter belongs to the system of fire pool equipment?
Not belong to. They all belong to hydrant water supply system.
Q:Water pump mutual switching device
The main purpose of the control is to make sure that the pump outlet has a nominal pressure.Control requirement: 1. Start single pump manually.2, two pumps should alternate.3, the pump exports to achieve certain pressure, the normal operation of the motor, and the pressure is too low, the operation is meaningless.Device: AC contactor, intermediate relay, etc..Principle: 1, detect a pump fault (usually take the motor main contactor, auxiliary contact), interlock another pump to start.2, pump outlet pressure detection device detects low pressure, can start another pump at the same time, to ensure the normal export pressure!
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. 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:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Look, the direction of the motor is the direction of that arrow. Point to the other side. That's the water out
Q:Explore the flow of water pump production process is like?
The selection of water culture equipment: processing and improvement of mineral water bottles, coke bottles, plastic barrels, glass bottles and so on. Design and manufacture of pipeline circulation device;From the hydroponics: root washing water method, interpolation method, clipping rhizome plant method, cutting method of tiller buds;The disinfection of plant roots or wound: 0.05 - 0.1% of the Potassium Permanganate solution soak for 10 minutes;Scientific cultivation: rooting and domestication, bottling and maintenanceB, a general management method for hydroponic plants:The root of the reasonable fertilization for washing the water to wash the leaves and proper ventilation timely pruning maintains health2, cultivars and quantities:A, selection of cultivated species: Based on the adaptability of plants to local environmental temperatureThe main products: green, Chlorophytum, iris, reineckea and other 5 - 8 pots, used to decorate the classroom office.Product development: Canna, jiupinglan, geranium leaves, Jasper, Calla, life Rong, money tree, pocket coconut, Schefflera, lotus and other stone 1 - 2 pots.B, the source of seedlings:(1) encourage students to actively participate in and prepare for saplings, such as iris, reineckea, Canna.(2) the market to buy a part, such as: Scindapsus, Chlorophytum, jiupinglan, geranium leaves, Jasper, Calla, life Rong, money tree, pocket coconut.
Q:Think of several households sharing a pump
Each contactor is connected with each power source in the main circuit, and the lower port is connected to the water pump;Control loop, only draw the wiring diagram of A households, households in other similar first power through the control switch in series contactor several other a normally closed contact and then enter the M contactor coil;In water, leading to various water pipes connected with the electromagnetic valve, and the solenoid valve are connected in series and the two contactor normally open contact is connected to the power supply;As long as one of the closed control switch, the pump will run at the same time, using his own power, and this is the other an open pump closed control switch of their own, will not work, the water will not go into his house, the family will not run electricity; only when the first home after closing the control switch second, if still closed control switch, water and electricity will automatically turn to him.Not understood, of course, that there is one drawback, if one is using a pump, a few other can not be used to solve the problems, it is not difficult, is that every installation of a water tank or like a floor, said each install a pressure tank on it
