Q:How to install, operate and maintain the pipeline booster pump?: When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.

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: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:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines? Why?: Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value

Q:What should I pay attention to when buying a pump?: Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.

Q:Does the control cabinet of the fire control pump need to be related to the fire control room?: The relationship is simple, the fire pump is pressurized water supply device, the control cabinet is the power supply for the fire pump, the regulator tank is to stabilize the pressure of the network management, reduce the pump frequently start device.

Q:Why should the pump be closed when the centrifugal pump is started?: Centrifugal pump has an important characteristic: when the pressure (head) is very low, the flow will be great, which can be seen from the characteristics of the pump curve. While the pump power is directly proportional to the flow rate, pump start, no pressure in the pipeline, caused by the pump flow, high power pump, and the pump motor, the rotating part from rest to high-speed operation, need a lot of acceleration, it will cause a great starting current

Q:Concrete pump 125 pipe wall thickness: Concrete pump diameter 125mm, pipe wall thickness is generally 4mm, also have 4.25mm, 4.5mm, 4.75mm, need to be in accordance with the rules of transport.

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 is the pumping property of concrete?: Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
