- Q: What does "anti pump" mean in pump operation?
- The pump again is the pump, the theory is the plugging problem can be solved, but if you are against the pump after pump has been plugging serious, and pump has been unable to solve the plugging problem, finally the worst solution is a split pipe, if the situation under enormous pressure will only exacerbate the plugging
- 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: What are the application areas of pumps?
- Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:
- Q: What's the difference between non negative pressure and variable frequency water pump?
- No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure
- Q: Is the centrifugal pump large or small?
- Centrifugal pump, the smaller the better the cavitation.1, centrifugal pump cavitation less, anti cavitation performance is better, the pump cavitation is called the necessary cavitation margin or pump inlet dynamic pressure drop, the smaller the better. Generally speaking, the pump cavitation is the need for cavitation, the pump inlet pipe said effective cavitation margin, that is, the device cavitation margin. For a given pump, at a given speed and flow rate required NPSH is called pump necessary NPSH, also called NPSH, is required to achieve the performance parameters of the pump cavitation, the internal flow and the centrifugal pump is composed of pump head itself, its physical meaning is that liquid drop in pump inlet pressure part degree, is to guarantee the pump cavitation does not occur, with surplus energy exceeds the vaporization pressure head at the inlet of the pump unit weight of liquid. The cavitation must be independent of the device parameters. It is only related to the parameters of the inlet of the pump. These parameters are determined by the geometric parameters at a given speed and flow.
- 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.
- Q: Common failure treatment of piston pump
- 1) overflow valve regulation is too high, overload after the pump2) the overflow valve spool is blocked, the central hole of the valve core is blocked or the overflow valve is blocked by a damping hole, and the overflow is not overflow3) pump outlet one-way valve installed or spool blocked and stuffy pump4) motor fault x091) adjust the relief valve pressure value2) repair valve boring3) overhaul check valve4) overhaul or replace the motor
- Q: What is the cause of the damage of pump bearings?
- In high-speed equipment, the most likely damage to bearings is high temperature.
- Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
- One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is 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. But that's not why if your booster pump isn't working properly all the time.
- Q: What flowmeter is installed after the pneumatic diaphragm pump?
- According to your entire pipeline system to flow meter ah!How about the pressure, the material, the digital float or what?You must be sure of the size of the flow
