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: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: The vertical line NHKVV-7*1.5 is the remote starting line of fire controller to fire pump room.

Q:How high can the pneumatic diaphragm pump be?: Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.

Q:Which nuclear submarines use the shaftless pump technology?: The team led by academician Ma Weiming of China is now carrying out the research on this technology and has achieved initial success.. This technology is expected to be applied to the next generation of domestic submarines.

Q:What is a gear pump for?: Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.

Q:I want to know the concrete under 60 type pump performance, it is mainly the pump long spiral bored piles, such as the diameter of the pump, transportation distance, pumping height and so on, thank you!: Specification for concrete cylinders:Bore * stroke mm 200 * 1650Hopper capacity L 800Feeding height mm 1400Motor model Y2-280M-4Power kw 90Rated voltage V 380Rated speed r/min 1480Soft starter withoutHydraulic system open-loop

Q:I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?: 15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.

Q:What is the difference between centrifugal pump and positive displacement pump?: The centrifugal pump is to rely on high-speed rotation of the impeller to do work on the fluid. These two types of pumps are also the most widely used.

Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.: Important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. The utility model is mainly used for farmland irrigation and water for human and livestock in mountain areas, and can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines and site drainage. General flow can reach (10m3~650m3) per hour, head up to 1500 meters.

Q:Variable flow pumps are variable pumps: Yes. The variable pump is designed to change the flow rate

Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?: Generally speaking, for the fixed size, not limited equipment, the pressure can be selected lower, walking machinery heavy equipment pressure should be selected higher.If the load is selected, the working pressure is as follows:Load <5kN, working pressure <0.8~1MPa;Load 5~10kN, working pressure 1.5~2MPa;Load 10~20kN, working pressure 2.5~3MPa;Load 20~30kN, working pressure 3~4MPa;Load 30~50kN, working pressure 4~5MPa;Load 50kN, working pressure =5MPa;For example, the system work pressure of various machines is as follows:Grinder 0.8~2MPaModular machine tool 3~5MPaLongmen planer 2~8MPaBroaching machine 8~10MPa agricultural machinery, small construction machinery, construction machinery, hydraulic drilling machine 10~18MPa hydraulic machine, large and medium-sized excavators, heavy machinery, lifting transportation machinery 20~32MPa.
