Q:Is the flow meter in front of the pump or after the pump?
After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
Q:Operating procedures for measuring pumps
First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.
Q:What is the difference between an air pump and a water pump?
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.
Q:What are the functions of a disposable infusion pump?
This is a very professional question, ha!I only know disposable infusion pumpsAttached: intelligent medical infusion pump and its application
Q:What is a feed pump?
In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
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:Significance of water pump model ISO50-160
According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What happens when a centrifugal pump is selected?
The air pump.The pump itself is mechanical failure.The pump outlet valve core off.Low voltage power.
Q:What do you mean by the self coupling device on the pump?
Overview of GAK self coupling device:The utility model relates to a GAK self coupling device, which is an automatic butt joint between a water outlet flange of a submersible electric pump and a water outlet pipe system.In the above additional coupling flange and the water outlet pipe seat inlet flange with a pair of wedge card, under the additional coupling flange and the water outlet pipe seat inlet flange and a pair of wedge cards in a wedge seat below the outlet pipe inlet flange card is made of elastic steel plate is fixed on the lower side of the seat pipe inlet flange. When the submersible pump water falling from above, Kaxianka additional coupling flange at the top of the wedge wedge and seat card outlet pipe above the inlet flange together, in the role of the dignity of the pump and submersible inclined wedge clamp, two flange will be put together in a pair of wedge under additional coupling flange and the water outlet pipe seat inlet flange the card will be in the elastic plate under the action of automatic card together. The utility model can solve the problem that a large amount of water leakage between the two flanges of the coupling is saved when the automatic installation and disassembly of the electric submersible pump is convenient, thereby saving energy.
Q:What is the dry running protector of screw pump? What's the principle and function? Thank you
The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air
