1. Structure of S Type anti-corrosive fiberglass centrifugal pump Description
The fiberglass centrifugal pump combines the motor and the pump components as a whole, relatively compact, easy to install with small power. It is mainly used in petrochemical, smelting, dyes, printing and dyeing, pesticides, pharmaceuticals, rare earth, fertilizer and other industries. The fiberglass centrifugal pump can transport slightly solid particles, not easy to crystallize. This pump is the essential ideal equipment for the corrosive media like some non-oxidation acid of not more than 100℃ (some acid temperature can reach 120℃).
2. Main Features of S Type anti-corrosive fiberglass centrifugal pump
•The products’ performance reaches the requirement of the trade standard JB/T8688-1998” plastic centrifugal pump”.
•Standardizing design, beautiful and dignified contour, reasonable and compact structure, universal parts and components, strong mutual changeableness.
•Optimum design of hydraulic model through Computer enables energy saving and high-efficiency
•Wetted components adopt phenolic fiberglass, through shaping under the conditions of high temperature and hot pressure, it has high strength and strong anti-corrosive performance.
•Axis sealing adopts Teflon mechanical sealing of outer-installing type with anti-strong corrosion and has extensively suitable scope with simple and reliable sealing.
•Single installation and convenient maintenance

5. Instructions
• The motor's revolving direction should be in conformity with the direction of pump's revolving direction pan. In order to protect pump from being damaged due to revolging in opposite direction, please first trial the revolving direction with hand to confrim the correct direction, then start the pump.
• Before starting, make the pump to be full of liquid; strictly forbid using concentrated acid.
• Don't allow pump idling without liquid, otherwise, the sealing end surface will be damaged due to dry friction.
- Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
- Working pressure - the actual working pressure of the motor, that is, the pressure of the input oil. The difference between the motor inlet pressure and the outlet pressure should be calculated.Rated (nominal) pressure under normal working conditions, according to the test standards for continuous operation of the maximum pressure, that is, the rated pressure, more than the maximum pressure is called overloading.
- Q:What should be used to pay attention to the use of mechanical pumps?
- There are many kinds of pumps, such as centrifugal pumps, piston pumps, diaphragm pumps, vane pumps, gear pumps, etc.
- Q:Is the centrifugal pump large or small?
- When the liquid is lowered at a certain temperature to the vapor pressure at this temperature, the liquid bubbles. The phenomenon of producing bubbles is called cavitation. When the bubbles are flowing to the high pressure, the volume of the bubbles is reduced so that they are destroyed. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse. The local pump is in operation if the over-current part (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began there, produce a lot of steam bubble formation, when the liquid contains a lot of bubbles by forward high pressure impeller Zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst and the liquid particle at high speed to fill a hole in this moment has a very strong effect of water hammer and the impact of high frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be. The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also produce noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.
- Q:When the water pump is started, why should it start when the outlet valve is closed? Thank you
- The valve opening pump is aimed at the centrifugal pump.From the power curve of the centrifugal pump, the power of the centrifugal pump increases with the increase of the flow rate; the flow curve of the centrifugal pump shows that the flow rate of the centrifugal pump decreases with the increase of the head.
- Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
- For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
- Q:The water tank of the fish tank does not air out and only has the water outlet
- The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.
- Q:Why does the centrifugal pump close the pressure to start?
- Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
- Q:What are the characteristics of a vertical multistage centrifugal pump?
- Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.
- Q:Pump unloading in hydraulic transmission,
- Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving
- 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.
