Product Description:

<1>Outline :

IS series single-stage end-suction (axial intake) centrifugal pump is an energy-saving pump designed by teamwork in the whole nation, it is improved on a basis on model BA, B and other single-stage water centrifugal pump. The advantages: its hydraulic capability is distributed reasonably, wide option for user, conveniently check and repair, the efficiency and throw is up to advanced international level. This pump is suitable for industrial and city water supply, water drainage, and widely used for agricultural irrigation, transportation pure water or other liquids whihc physical and chemical nature is similar to pure water, and the temperature should not be higher than 80 .  

 

<2>Features:

1)Speed: 2900RPM and 1450RPM;
2)Suction: 50~200mm;
3)Flow/Capacity: 6.3~400m3/h;
4)Head: 5~125m.

<3>Application:

a)Municipal water supply and drainage

b)Water circulation of air conditioner

c)Agriculture hydraulic engineering,such as irrigation,drain flooded fields etc.

d)Industrial water supply system,fire fighting system,drainage of heating system.

e)Transport of clean water or liquid of which physical chemical properties similar as water

<4>Construction

1. IS series single-stage end-suction centrifugal pump is designed ac cording to the capability and size stipul ated i n the internati onal Standard ISO2858, it is composed of pump body,pump cover, impeller, shaft, ring seal, sleeve and suspended bearing units.


2. The pump body and pump cover in IS series are separated from the back of impeller, that is to say in general, back open structure, whose advantages: convenient overhau l,when checking and repairing, the pump body intake pimp,discharge pipe and motor need not to move, just disassemly the middle connector of extended coupling to quit therotor units for overhaul.


3. The pump shell (that is pump body and pump cover)forms the workroom of pump. Impeller, shaft and rolling bearing are the rotors for the pump. Suspended bearing units support the rotors in the pump. The rolling bearing stands the radial load and axial force.


4. In order to balance the axial force of the pump, most of the pumps are designed with sealing rings at the front and back of impellers and a balance hole on the rear impeller cap plate. The reverse of impeller is not designed with sealing rings or balance holes if pump axial force is not powerful.

Q:Why can't the inlet of centrifugal pump be negative pressure?
However, the centrifugal pump will have its import pressure requirements, which is to prevent cavitation, that is, the fear of the delivery of liquid at low pressure will occur gasification. Centrifugal pump has an important parameter called NPSH, for example relating to the inlet pressure, the pump NPSH, 4 meters, it means that the absolute pressure of imports should be higher than the saturated steam conveying fluid pressure of liquid column is 4 meters high, so, when it is at a temperature of saturated vapor pressure for water transport 2 meters, 4+2=6 meters minimum inlet absolute pressure. Because the absolute pressure is 10 meters water column atmospheric pressure, at this time the entrance negative pressure is 10-6 meters =4 meters water column.
Q:Troubleshooting of diaphragm pump
The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture
Q:How to select the fire pump?
Such as a large pressure of about 10m or about 0.1MPa} because the most unfavorable point fire hydrant requires more than 0.07MPa (7m) and 0.5MPa (50m) is not greater than the pressure, so unless the pump is located in the 50m Valley is still lower than the garage, or add to the valve (or the use of fire hydrant decompression) otherwise, it is 120m lift pump
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
Centrifugal pumps are used to transport liquids (or mixtures, waste water, waste materials) from one location to another.
Q:What are the problems that should be paid attention to when using vacuum pumps?
(8) in the process of running the pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.(10) vacuum pump to stop using, first shut down valve, pressure gauge, and then stop the motor. (11) vacuum pump in the first month of work, 100 hours after the replacement of lubricating oil, oil every 500 hours after the change.(12) adjust packing gland regularly to ensure the normal condition of drip in packing room. (13) regular inspection of shaft sleeve wear, larger wear should be replaced in good time.
Q:Why is the submersible pump tripped on an electrical switch?
Calculate or refer to the water pump nameplate that the normal operating current, according to this data exchange switch.2) with 500V shaking table, measuring the cable, motor insulation is in line with the requirements
Q:What are the differences between the sewage pump and the clean water pump?
The main difference between the sewage pump and the clean water pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.
Q:The function of centrifugal pump
2, pump body, also known as pump shell, it is the main body of the pump. The utility model is provided with a supporting and fixing function and is connected with a bracket for mounting the bearing.3, the role of the pump shaft is to use the coupling and motor connected, the motor transfer distance to the impeller, so it is the transfer of mechanical energy of the main components.
Q:What is the principle of a turbopump?
The working conditions of the turbine are different from those of the medium used, so the structure of the turbine is varied, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) mounted on a turbine shaft with blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work.
Q:How many kilograms of water pump are there in the automatic washing machine on the market?
High pressure pump pressure can reach 4--8kg, flow 5 liters, work current 4 or so.
