Product Description:

1.Introduction

 

JSP/JSW series are suitable for pumping clean water. They are particularly suitable for domestic applications such as supply water from well, pool etc, the automatic distribution of water by surge tanks and pressure switch, gardening, and increasing of water pressure.

 

2.Features

 

a.JSP/JSW Series pump is constituted with clean water pump, non-return valve and air-water separation room, which located on the upside of the pump body.

b.During operating, it is no need to use foot valve, the only thing that you should do is just leave some water in the pump body.

c.After a few minutes' running, the water will be sucked out relying on the pump body itself.

d.They are particularly suitable for domestic applications such as supplying water from well, pool etc.

e. It is also suitable for water pressure boosting, gardening and automatic water supplying if combined with other appliances.

 

3. Construction

 

Pump Body: Cast Iron/Stainless Steel/Brass Front Cover: Cast Iron/Cast Iron with brass insert / Aluminum / Brass Impeller: Brass/Aluminum/PPO Mechanical Seal: Carbon/Ceramic/Stainless Steel Motor Housing: Alloy Aluminum Shaft: Carbon Steel/Stainless Steel/High Frequency Wedding Shaft Insulation: Class B / Class F Protection: IP44 / IP54 Cooling: External Ventilation

Q:Attention should be paid to the use of pumps?
To carefully check whether there is a crack impeller, impeller fixed in the bearings are loose, if there are cracks and loose, hungry phenomenon should be promptly repaired, if the pump impeller above the soil should also be cleaned
Q:What are the basic technical parameters of the pump?
The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:
Q:Advantages and disadvantages of canned pumps
The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:What is the pumping property of concrete?
Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,
Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
[suppression of pumping voltage] the general use of the installation of absorption resistance to absorb the pump voltage rise. The simplest way to control the pump voltage is to connect the DC bus with an energy consumption resistor before releasing the pump voltage.
Q:60 type concrete pump performance?
Specification for concrete cylinders:Bore * stroke mm 200 * 1650Hopper capacity L 800Feeding height mm 1400Motor model Y2-280M-4Power kw 90Rated voltage V 380Rated speed r/min 1480Soft starter withoutHydraulic system open-loop
Q:What is the pump delivery? What's the difference between years and years?
Secondly, the landlord asked the question, although I did not go to the insurance company to practice the operation, but to my four years of learning, as well as internship experience, or can help you analyze, and I hope to help you.Pay is a one-time payment of premium -- all wholesale D sea n
Q:How to select the fire pump?
According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion
