Product Description:

 

                        End Suction Centrifugal Pump

1.Structure of End Suction Centrifugal Pump Description

End Suction Centrifugal Pump complies fully to the European Standard BS EN733 / DIN24255 of performance and dimensions. They are used for pumping clean water or liquids similar to water, achieving wide application on plants, mines, city water supplies, air-conditioning coolers, firefighting system and irrigation. Pumps of the same model have different performance levels basing on different diameter after impeller trimming. Overall the whole series, there are only four sizes of shaft and five of bearing housing. As long as their bearing housings are of the same size, different pumps can interchange chief parts such as shaft, shaft sleeve, shaft seal, impeller nut, etc.

End Suction Centrifugal Pump is also very easy to be installed and maintained. Back pull-out design, driven through flexible coupling, so that pump casing and motor can remain in position while other spare parts are removed.

Q:How do you do the yellow water from the suction pump?.
If your pump is iron, it must be impossible to avoid rust, and if you replace it with stainless steel, there will be no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.You can change the flow parts into stainless steel, but the price may not be cheap
Q:Pump house should be equipped with those equipment and valves
1. The inlet and outlet of the pump shall be equipped with a control valve, and the outlet shall be equipped with a check valve;2, lower than the pump suction the water tank, water pump entrance to bottom valve, and piping and valves equipped with irrigation. Or equipped with other water pump irrigation facilities.3, more than one pump system should have the total valve and contact valve.4, the corresponding control equipment.
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。1, the system is designed according to 2+1, 1 standby, only redundant backup of important equipment, not included in the running load.2, higher power distribution only provides 2 (maximum operating conditions) equipment rated operating power capacity (slightly margin, but limited).3, a single 160KW motor rated current is about 300A, 185 cable can only be used for the 1 pumps (with 2 units, and has overload) 630A circuit breaker is the frame level, if the current setting value is 630, it should be the main power switch (single pump with 400A circuit breaker, setting a value of 315 or 350A).4, if the 630A as the main switch to provide 2 pump power, has been close to full load (third pumps can not be added).5, water pipeline system, although not what caused the problem, but the water flow rate, flow rate of 2 pump operation should be in the ideal range, adding third pumps (the premise is to ensure the power supply) will make the water flow velocity is too large, in non ideal conditions.Conclusion: this method is inadvisable. If necessary, modify the original system, change to 3+1 mode, and change the line and circuit.
Q:What is the defection of water pump
Anti water hammer phenomenon that is usually said, it is in the high pressure water pump suddenly stops working, the height would hit back phenomenon called defectionThis situation generally occurs in the water pump outlet does not install a check valve, the valve with a check valve has a sound, but the check valve can be a good protection of water pump
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
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:Two pumps automatically switch start control circuit,
Can add time delay relay, the key depends on how much time the water is full, if you design is automatic, it is better to use the triode reliable,
Q:37KW how many contactors does the pump need to start directly?
Direct start requires 250A contactor.Contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC). It is applied to power, power distribution and power consumption. Contactor broadly refers to the use of coils in industrial electricity that flow through the current to produce a magnetic field, so that the contacts are closed so as to control the load of the appliance.
Q:2 pumps parallel, lift the same, pump head is not stacked?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.
Q:The role of water replenishing pump in circulating system
There are three ways of constant pressure in water system. 1, the expansion tank constant pressure, this method applies to small and medium water systems, low cost. 2 water pump constant pressure, the role is when the system because the water shortage during the operation, resulting in insufficient pressure, the water supply system can play the role of water pressure. 3 pressure tank fixed pressure, pressure tank fixed pressure at the same time, also need replenishment pump water, the individual feel that the first two kinds of economic reality
