Structural Characteristics of Single Stage End Suction Chemical Pump

Bearing support,shaft,sealing box and impeller form an installation module,which can be changed among different pumps in order to save the holding cost of spare parts.In the meantime,after dismantling separable coupling,there is no need to dismantle pipeline and motor before disassembling the installation module formed by Bearing support,shaft,sealing box and impeller.

(1) Pump casing

Single volute and double volute structure shall be designed on the pump casing,with interchangeable impeller ring on the pump casing to protect pump casing from abrasion.And pump casing shall also be designed with the structure of heating jacket.

(2) Flange position

Inlet flange is horizontally suctioned,outlet flange is radially upwards.

(3) Hydraulic and axial force balance

Performance curve is stable with low cavitation and high efficiency,and this characteristic shall be kept like this even when load is not enough.

(4) Bearing and lubrication

Single-row ball-bearing and thin oil lubrication shall be applied on the bearing;bearing sealing is labyrinth seal;oil level is automatically controlled by a constant oil cup.

(5) Shaft seal

Mechanical seal box or packing seal box shall be applied on the shaft seal,and seal box can be cooled or heat retaining,shaft seal can be cooled or washed.

(6) Flange pressure rating and rotation direction

Flange design pressure rating is PN16 and PN25,and ANSI125,150 is also applicable.

The pump rotates clockwise from the direction of motor end.

FAQ

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: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q: If I increase the power of the motor, must I also increase the power of the inverter?

A: You must select the size of converter that allows maximum absorption of the electric motor.

Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
60Hz pump and 50Hz pump itself is not much difference, just that the motor speed, the rated speed is 3600 rpm, 1200 rpm, 1800 rpm, the latter is generally 3000, 1500, 1000 etc.. If it is to use the same pump, the difference is that the 60Hz motor pump flow is 50Hz, motor water pump flow of 1.2 times, the lift is 1.2*1.2=1.44 times, power is 1.2*1.2*1.2=1.728 times. So in the actual manufacture, especially some relatively large flow lift pumps, pump motor using 60Hz to use 50Hz thicker than the spindle motor of the pump impeller, the difference between the two, in addition to empty size shaft is different, what basically no difference. As for the data of package angle, the water conservancy models of different factories are different, but I don't know whether there is any difference between them. Most of them make no difference. However, if you want to use the 60Hz pump to achieve the same flow rate as the 50Hz pump, the impeller of the former should be cut to 0.833 times the size of the latter.
Q:Why should the water pump be opened in time after the pump is started?
Just like peeing, just getting ready to pee, it feels like holding a chicken.
Q:How to connect the household pump capacitor?
1) in a line in the AC220V string into a large light bulb (Bai Chideng), and then the capacitor as shown in figure A, then, that B and C are three terminals; 2) the number of pump motor three lines 1, 2 and 3; 3) A, B, C and 1 2, 3, a total of six kinds of wiring combination: ABC/123, ABC/ 231, ABC/321, ABC213, ABC132 ABC312; 4) you have a a try, if you can turn up, and the fastest start wiring is correct, 5) if not turn up, you have to increase the number of watt bulb, such as 200 watts, 300 watts, 500 watts...... With a few 100 watt parallel one; 6) string into the bulb is designed to prevent the current is too large, it certainly must be removed after determining the connection method; 7) there is no suitable bulb that according to the motor power generation to choose the appropriate insurance.
Q:What are the quota items for the complete pump installation?
Pump installation / anchor bolt installation anchor bolt hole, fill oar vibration cushion installation
Q:What is called soft start of water pump?
Soft start has many methods, mainly used in high-power motor.Through soft starter, or frequency conversion start, or star triangle start to achieve.It means that it starts at a slower pace.
Q:After the pump has a control box, but also the distribution box?
What you are saying is not a concept. The function of the control box is to control one or more equipment and to protect the equipment. The function of the distribution box is to distribute the power. The control box is connected to the power box, and the power box may be responsible for several devices at the same time. The distribution box is just one of them.
Q:90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?
The first thing to take the star delta start voltage step-down start, star rated by reducing root 3 times, power is also reduced, 90kw / V 3 = 52kw starting current is 5---7 times will reach the rated current of 52kw * 2 = 104A, starting current will reach 500----700A is normal, if you match breaker sister ordinary 800, D at the beginning of the special motor, they start filtering instantaneous current, 250 can be,The star delta starts with only three contactors, and there will be no 4The contactor can be more than 110
Q:The problem of single phase pumps
Is your starting capacitor pump is broken. Because you pump it is a single asynchronous motor..... Single-phase asynchronous motor by capacitive phase shifting function, the single-phase alternating current isolated from another 90 degree phase alternating current. The two alternating current into two groups or four groups of motor winding, forming a rotating magnetic field inside the motor rotating magnetic field induced current in the rotor, the induced current magnetic field and rotating magnetic field in the opposite direction, by rotating magnetic field push pull into the rotating state, because the rotor must be cutting magnetic lines to produce induction current, so the rotor speed must be lower than the rotating magnetic induction motor speed, so thatSo if the starting capacitor is broken, then your pump will start difficult,
Q:(flood control emergency plan) what type of water pump should be used for flood control? How to choose
Select the QW submersible pump, which is potential water, (flow, lift, bore, power)Flow, how many tons of water pump an hour to play, you choose how much?Lift, water pump from the destination is a few meters, how many meters?,Caliber, this pump potential water, without flange connection, only flow, head can reach.Power, look at the flow and lift is how much, and then choose the right motor (this is regular)The voltage is usually 380V.You can move, it is best to fix a seat, weight, this pump is basically a person can not move, and small can take.Brand, regular manufacturers can.Model, (caliber, flow, lift, power, voltage) tell the manufacturer.
Q:Horizontal pumps, vertical pumps, which kind of expensive?
Not expensive, depending on the specific model, in fact, the vertical pump is not much
