Product Description:

Range of use of Water Supply System with No Negative Pressure

1. In order to adapt to the social development with the improvement of the living standard and qualit.

2. Additive pipe pressure (negative pressure) water supply equipment emerge as the times require, the device makes full use of the municipal pipe network pressure superposition, pressurized water supply, .

3. Superposition of pressurized water supply, small occupation of land, energy saving and environmental protection.

4. Tank structure superposed pressure (without negative pressure) water supply equipment long time over the municipal pipe network water supply operation condition of water use in the user, because the regulating tank storage capacity is limited, can not guarantee the normal water use of users, as well as the municipal pipe network short water, be no water available to the problem, in order to make the equipment performance to be more perfect, the company in on the base of original technology developed a new generation of the network pressure superposed water supply equipment of BW (III) type pipe network pressure superposed (non negative) frequency conversion water supply equipment.

FAQ

Q: Where do I have to send pumps for service?

A: You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

Q: Are your pumps acid-proofed?

A: To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

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.

Q:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
Q:what kind of noise does a water pump make when it is going on a car?
There is no noise associated with a water pump going out that I am aware of other than the engine exploding due to excessive heat. The dash guages; especially the engine temp guage, will give you a clue as to a cooling problem, whcih is what the water pump is for. The water pump prevents the engine block from overheating. When the pump fails, the engine overheats and will either shut down, or the engine will burn out. The best way to tell is to monitor the temp guage. If the engine is running hot, it either the water pump, lack of water in the cooling system, or Thermostat failure. Best to have a mechanic check it out. Cheers!
Q:The flow of the pump will be reduced, the speed will change, the power of the motor will change?
1, this pump flow reduction is not the reason for speed. Because it is not matching the motor frequency conversion, the frequency of power supply unchanged, the motor speed will not change.2, the flow of water pump down, the reason may be that the impeller due to cavitation or wear and tear smaller, second, the gap between the impeller housing change, and the impeller plug foreign bodies, and some of the suction port leak.3, it is possible that the whole system resistance increases, so that the work point of the pump left.
Q:Sim City for iPhone, help! Water Pumps?
I think it might be a glitch in the game. I'm having the same problem and I've looked around the net and found others with the same problem. I also had problems getting the power to work, but found if I exited the game and started it again I would magically have power. It hasn't work for the water though but you can give it a shot. I deleted the game and reinstalled and that did not help either. NEVERMIND. ALL YOU HAVE TO DO IS HIT PLAY AND WHEN PEOPLE COME THE WATER WILL PUMP!
Q:Why does my water pump switch on and off about every 5 seconds?
It sounds like the bladder in your pressure tank has ruptured.
Q:Is my water pump failing?
17 Years...... Blown Head Gasket, Fans need to be Repaired {A/C Fan on at all times with A/C on, Radiator Fan Cycling as Engine Heats Cools}, Thermostat Removed, Cooling System Boiled/Flushed Out, New Thermostat Installed After Cooling System Cleaning, At 17 Years New Radiator Hoses Clamps, New Radiator Cap, New Temp. Sensor, New Coolant (50%-50% Anti-Freeze Clean Water Used All Year Round). Hopefully that should fix it. Almost forgot; With a Blown Head Gasket there will be Water in the Oil, you should Flush the Engine and change the Oil Filter.
Q:help.. how do I change the water pump?
the easiest way is to have some one else do it//if you finally end up doing it yourself dont forget to change t/stat at same time
Q:what's wrong with my water pump?
Easiest way to tell is to bypass the pressure switch and connect the pump motor wire directly to incoming power and manually run the pump until you reach shut off pressure... use your circuit breaker to do this.. My guess is that when you wired it the wrong the first time you forced the pump to shut off by way of an overload protector on the motor and either the protector is bad now or the motor is
Q:how to convert a deep well pump to shallow well?
move it up only difference is how far the pump will push water, you will get better pressure from a deep well pump,
Q:About drive-belt, timing belt, and water pump of a Tpyota Sienna?
Change the the timing belt if it breaks you can bend a valve the smaller import engine have what they call a zero (0) tolerance.For the water pump it runs off of the timing belt so since your timing belt is already off you should change the water pump.Another words you will need to tear the timing belt back out in order to change the water pump not if but when it goes out.The dealer price is not bad for a dealer you might be able to save a little more if you shop around GOOD LUCK
