Q:What is the lift of diaphragm pump?

Hello, pneumatic diaphragm pump head is liquid, the energy obtained through the pump is called the head, it is related to the flow rate and pump speed, liquid density.Please adopt.

Q:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role

Then control the speed level, to achieve the purpose of regulating the speed and flow of the feed water pump.

Q:Concrete pump 125 pipe wall thickness

Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q:Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?

Submersible pump cable or motor insulation is damaged.3) motor water solution

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:The difference between diaphragm pumps, vacuum pumps and centrifugal pumps

The diaphragm pump and centrifugal pump refer to the structure of the pump, and the vacuum pump means the use of the pump. There is no comparability between them.Centrifugal is the sign of inertia of an object. As the umbrella turns, water droplets move out of the outer edge of the umbrella and are thrown out. This is what is called centrifugal. Centrifugal pump is designed according to this principle. The high speed rotating impeller blade drives the medium to rotate and is thrown out so as to achieve the purpose of conveying.

Q:Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center

Multi line linkage NHBVR-4*1.5 is a positive pressure blower and smoke exhaust machine fire fighting equipment

Q:What are the important parameters of the pump?

Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said.

Q:Is the flow meter in front of the pump or after the pump?

After the pump, the reasons are as follows, before the pump, you pump fluid through the pump will produce negative pressure in front of the pump, negative pressure on the flow of the life of the impact, the pump will not, Suzhou first Chi meter
