4. FAQ

1) Are CNBM pumps available in DIY stores?

Yes, currently, we’re available for DIY stores all over the world.

2) Where do I have to send pumps for service?

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

3) Are your pumps acid-proofed?

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:Fire pump control cabinet There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, and two outdoor pumps
You said the three line refers to the control room, the control cabinet, the main pump directly start the straight line of water pump. Each pump should be equipped with single straight line Kai, reported that the cabinet Jinglian dynamic multi line linkage control board has three buttons corresponding to a remote spray pump, fire hydrant pump, pump start outdoor fire hydrant. This requires three straight lines, from the cabinet to the three pump control cabinet, which is the 9 line you call. The water pump control cabinet is provided with a terminal for supplying a remote pump. By looking at the wiring diagram of the water pump control box, you can find the technical personnel of the control cabinet manufacturer if you can't find them.
Q:Working principle and diagram of axial piston pump with pressure compensation variable
Adjust the flow characteristics, the first limit screw to the top, according to the flow and pressure changes in the required range, adjusting the spring set, the initial flow pressure began to change to meet the requirements, then the limit screw to the ultimate pressure when the flow is no longer changed, the relationship between flow and pressure the changes are determined by the pump itself.
Q:How many concrete pump tube diameter
Different pipe diameter is different, most of the 125, there are 150. Now we have the smallest pump on the market, with a pipe diameter of 100.
Q:Advantages and disadvantages of centrifugal pumps?
The uniform liquid no pulse phenomenon.(2) shortcomingsBefore running, the pump must be filled with liquid.For the supply of small flow, large pressure head inappropriate, inefficient and limited.Encountered imperfect design or operation is not at the time, such as milk, it is easy to produce foam, affecting the next process production.The installation is wrong. There will be "Qi tie" phenomenon.The efficiency is also lower than the reciprocating pump.The sources of knowledge are absolutely reliable!!!!
Q:What is a positive displacement pump? He Weizheng displacement?
And includes a pump chamber (24) to open and a channel is arranged between the entrance and the pump chamber (26) in the second one-way valve (15), and one for the continuous displacement member (13) in the pump shell (10) in the travel section (S) actuating mechanism reciprocating motion.
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
Q:What is the name of the day pump and ground pump? Specific introduction
PumpGround pumps are used very frequently in many large basements, because they have no boom, so they need to be taken over manually. In addition to the site, for those days to pump the high-rise buildings, such as 200 meters or 200 meters altitude, can also take over to transport concrete by pump, but the premise is to have enough power to pump concrete will hit above the height and the length of nozzle can reach the height of the floor.Thus, the day pump and ground pump have their respective advantages. The pump is easy to use, but the ground pump can make up for the height that the pump can not reach. At the same time, the price is relatively cheap, so users can choose the corresponding concrete pump when they are in use.
Q:How many millimeters is the diameter of the water outlet of the four inch pump?
If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.
Q:Water pump outlet valve sequence
In order to prevent the generation of water hammer when the pump stops the damage to the rubber head, should be immediately set rubber head pump outlet, the gate valve and the check valve is not a very convincing reason to decide the order of habits in our hospital order rubber head, check valve, gate valve1. Check valve located in front of the pump, I do not know what the significance is too great to think of.2. The actual installation sequence shall be: soft fittings, check valves, gate valves. The pressure gauge is best installed on the water outlet of the pump, but it must be in front of the check valve.Reason: 1) the soft joint is used to reduce vibration. The connection between the pump and the piping system, of course.2) normal work, the gate valve is not operating, and the check valve is frequent action, so the probability of maintenance is larger, when the maintenance of the pump closed, the water outlet valve can be maintained without affecting the normal operation of the system.3) the pressure gauge is installed in the check valve, which can prevent the impact and damage of water hammer on the pressure gauge.
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
