5.FAQ

①What is the applications?

Besides irrigation and drainage pumping Station, the Single Stage Double Suction Split Casing Centrifugal Pump also can be used for Circulation water for air-condition, water supply for industry and building, and other waterworks.

②How to guarantee the quality of the products?

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance. Normally, We have 1 year warranty.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. It related to the state and detailed requirement of customers.

Q:What are the main performance parameters of the pump?: The main performance parameters of the pump are:The energy obtained by pumping a unit weight of liquid through a pump. In H, the unit is m.

Q:When the water pump is started, why should it start when the outlet valve is closed? Thank you: When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.

Q:There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, two outdoor pumps, three units, one master and one spare control cabinet. From the control room to the control cabinet, is there only 3 lines or 9 lines?... How do I get it? Where does the hydrant line come from?: You said the three line refers to the control room, the control cabinet, the main pump directly start the straight line of water pump. Each pump should be equipped with single straight line Kai, reported that the cabinet Jinglian dynamic multi line linkage control board has three buttons corresponding to a remote spray pump, fire hydrant pump, pump start outdoor fire hydrant. This requires three straight lines, from the cabinet to the three pump control cabinet, which is the 9 line you call. The water pump control cabinet is provided with a terminal for supplying a remote pump. By looking at the wiring diagram of the water pump control box, you can find the technical personnel of the control cabinet manufacturer if you can't find them.

Q:Shielding pump is the main drawback of electricity? How much does it cost more than an ordinary centrifugal pump? Is there any noise in the running of the canned pump? How much is it lower than the noise of the common centrifugal pump?: Product featuresThe integrated structure of motor and pump adopts static seal, so that the pump is completely free of leakage;Full closed and no leakage structure, can transport toxic and harmful liquid substances;The shielded water-cooled motor and the cooling fan are removed to make the pump operate in a low noise and quiet condition. The utility model is suitable for occasions with high environmental noise requirements;

Q:If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?: The air pump.The pump itself is mechanical failure.The pump outlet valve core off.Low voltage power.

Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?: Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa

Q:How can I buy a pump?: Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.

Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.

Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?: Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly. CJWFG-DYG non negative pressure superposed water supply system:

Q:I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?: (4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.
