Product Description:

Model S pump is a single-stage double-suction horizontal split centrifugal pump and used to transport pure water and the liquid of both physical and chemical nature similar to those of
water, the maximum temperature of which must not be over 80 ℃,suitable for water supply and drainage in factories, mines, cities and electric stations, waterlogged land drainage and irrigation of farming land and carious hydraulic projects.
This series pump comply with the standards of GB/T3216 and GB/T5657.

Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the axial line, the pump casing is opened in the middle so it is unneccessary to remove the water inlet and outlet pipelines and motor(or other prime movers). The pump moves CWviewing from the clutch to it. The pump moving CCWcan also be made, but it should be specially noted at order.
The main parts of the pump are: pump casing(1), pump cover (2), impeller(3), shaft(4), dual-suction seal ring(5), muff(6), bearing(15) etc.and all of them, except the axle which is made of
quality carbon steel, are made of cast iron. The material may be replaced with others upon different media.
Both pump casing and cover form the working chamber of the impeller and there are threaded holes for mounting vacuum and pressure meters on the flanges at both inlet and outlet and for water draining on the lower side of them.
The impeller is static-balance calibrated, fixed with the muff and the muff nuts in both sides and its axial position can be adjusted via the nuts and axial force gets balanced by means of
the symmetrical arrangement of its blades, there may be residual axial force which is borne by the bearing at the axle end.The pump shaft is supported by two single-column centripetal
ball bearings, which are mounted inside of the bearing body on both ends of the pump and lubricated with grease. The dualsuction seal ring is used to reduce the leak at the impeller.

Q:What are the reasons for sealing damage of centrifugal pumps?
The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.
Q:Concrete pump 125 pipe wall thickness
Currently mainly divided into gate valve, concrete pump and S valve concrete pump. Another is a pump consisting of a pump body mounted on an automobile chassis and fitted with retractable or bent cloth poles
Q:How many kinds of pumps are available and the operating principles of various pumps?
There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;
Q:Common failure treatment of piston pump
Table 15 common troubles and treatment of hydraulic pumpsFault phenomenon, x09 cause analysis, x09 elimination method(1) the pump does not carry oil; the x091. pump does not turn x09 (1); the motor shaft does not rotate1) missed connection power supply2) electrical wiring and component failure, x09 check electrical and troubleshootx09x09 (2) motor heating trip
Q:Metering pumps related matters
Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
Why is it easy to produce cavitation when the inlet flow of pump is lowered?This is because the main performance parameters such as the head, power and efficiency of the centrifugal pump are not fixed, but vary with the flow rate. The curve drawn on a coordinate paper is called the performance curve or characteristic curve of the centrifugal pump. What happens when the flow rate decreases? The disadvantage of throttling adjustment is that the pump flow is small, and the impeller is easy to cause cavitation
Q:What is the distance between the pump and the wall?
What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
Q:How can I buy a pump?
3 、 mechanical requirements of high reliability, low noise, vibration.4, the correct calculation of pump procurement costs, the pump manufacturer to inspect, requiring good quality equipment, good after-sales service, spare parts can be timely supply.The micro pump and the motive of the mechanical energy or other external energy transmitted to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.The technical parameters of pump performance include flow, suction, lift, shaft power, water power, efficiency and so on.
Q:Water pump can not be pumped out, how to maintain water?
Packing overheating:Due to packing too tight, the cooling water can not enter the filler, or the shaft surface damage. Measures for proper relaxation of packing and cleaning of sealing pipe are adopted. Filler wear must be replaced with new ones. Before installation, soak in the oil and rotate it in turn. The incision should be staggered so that water leakage can be reduced. Fill the last lap after installed loading pressed to cover operation for further adjustment of the tightness.
Q:What is pump suction work?
Pump is mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.
