Features

1.Very high safety of operation. Mechanical actuate diaphragm. Changeable eccentric drive

2.Power off seal,no leakage,with security delivery device,simple maintance

3.It can transport high-viscosity mediums, corrosive liquid and dangerous chemical goods.

4.The flow can be controlled via adjusting the length of stroke or the motor frequency.

5.The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.

Purpose

Widely used in petroleum, chemical industry, electric power, metallurgy, mining, shipbuilding,light industry, agriculture, national defense department and etc.

Q:What is the lift of diaphragm pump?: Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.

Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?: The choice of pressure depends on the size of the load and the type of equipment. Consideration shall also be given to the assembly space, the economic conditions and the availability of components for the actuators.In the case of a certain load, low working pressure, is bound to increase the structure size of the actuator on some devices, the size must be limited, from the perspective of material consumption is not the economy; on the other hand, the pressure to choose too large, the pump, cylinder, valve and other components of the material, sealing and manufacturing accuracy requirements very high, must raise the cost of equipment.

Q:A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: Such as a large pressure of about 10m or about 0.1MPa} because the most unfavorable point fire hydrant requires more than 0.07MPa (7m) and 0.5MPa (50m) is not greater than the pressure, so unless the pump is located in the 50m Valley is still lower than the garage, or add to the valve (or the use of fire hydrant decompression) otherwise, it is 120m lift pump

Q:How many square cables does the submersible pump for 7.5KW need?: I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).

Q:What kind of motor does the hydraulic pump need?: Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused

Q:Why does the centrifugal pump close the pressure to start?: The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.

Q:What should I pay attention to when buying a pump?: There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.

Q:What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?: You're talking about a centrifugal pump. His series says the number of slices of the impeller (excluding the wheel, that is, the wheel)

Q:What is the difference between swashplate pump and crankshaft pump?: In hydraulic system:Axial piston pump is the use of parallel with the transmission shaft in the plunger plunger reciprocating movement of the volume changes generated by the work. As the plunger and the plunger hole are circular parts, processing can achieve high accuracy with the high volume efficiency, stable operation, good flow uniformity, low noise, high working pressure, but the hydraulic oil pollution is more sensitive, more complicated structure, high cost.

Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?: If you're allowed to spend a minute, you can do it 20 times a minute, and that is, the amount of water you sprinkle at a time (1000) is *20.1000 (ML) *20=20000 ml =20 liters, this is the flow,Here is a formula for you to see,Pump displacement * pump speed = flow,
