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: How can the submersible pump level meter be connected?: Install liquid level controller, two position liquid level sensor, controller to buy manual, wiring according to wiring diagram.

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

Q: What is the principle of a turbopump?: A machine that converts the energy contained in a fluid medium into mechanical work [turbine]. Also known as turbines, turbines. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object". The working conditions of turbines are different from those of the employed ones, so their structure types are various, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) that is mounted on a turbine shaft and has blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work. According to the turbine working fluid used can be divided into different turbine (used as a power source of Hydropower Station) and steam turbine (used in thermal power plant, ship propulsion), gas turbine (used as jet propulsion, ship power, and power plants, with a small peak load power station and air turbine (only) as a small power).

Q: Why does the centrifugal pump start and close first when the outlet valve is closed?: When the valve is closed off opposite is the first current to the rated current, avoid instant electricity loss of other electrical equipment caused by voltage fluctuation. At the same time, some centrifugal pump outlet check valve is not installed, the role of avoiding the pipeline caused by backflow of water pump reversal.This Regulation (or operation regulation) is generally applicable to larger power centrifugal pumps. For small power equipment, it can be used to determine whether the above operation is necessary for actual use

Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?: With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related

Q: What are the conditions required for hydraulic pumps to complete oil absorption and compression?: 2, the change of working volume is periodic, and in each cycle, the oil absorption process is changed from small to big, and the process of oil pressure is changed from large to small;3, suction oil cavity must be separated from each other without interference.

Q: What are the main performance parameters of the pump?: The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.

Q: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?: Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.

Q: Metering pumps related matters: 2) change the metering pump diaphragmTrouble is often encountered when the old diaphragm is removed. Provide some additional advice on how to remove the old diaphragm.After in the pump head loose, remove the pump head before the stroke length adjustment to the 10% position. To ensure that the electromagnetic axis has sufficient pressure to maintain its connection firmly, so that you can unscrew the diaphragm.The pull end torque from the Jack out of the screw. Seize the liquid counter clockwise rotation. There is a slight resistance that can unscrew the diaphragm.Chemical 3 measurement may end in fluid crystallization, resulting in a one-way valve ball and seat valve does not work.In the end inhalation metering pump may have a gas leak. Hydraulic end suction side connector may lack O ring or suction valve connection loose.3) flow monitoring and measurement of a high viscosity medium, in the process of liquid delivery received a flow failure signal, how can we solve this problem?Move the hydraulic end by loosening the 4 pump head screws. Rotating stroke length to 10%, and seize the hydraulic end, and then slide out of the screw hole, then the screws do not touch them, but still control the back and diaphragm. Then rotate the component counter clockwise, with a slight resistance, and the diaphragm will loosen from the electromagnetic axis. If the diaphragm is not loose, use some grease on the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer. Then proceed again in accordance with the above description.

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.
