Car tank monitoring device

Automobile oil tank monitoring device is based on embedded computer technology and communication technology as the foundation, uses the method of modern control theory to the automobile fuel tank quantity change of the velocity measurements and the amount of oil detection. oil tank monitoring system , Piecewise linear function to obtain the change of voltage and the amount of oil through the change curve change simulation oil quantity and fuel sensor voltage, the system according to user needs to set the sampling time, voltage sampling timing oil sensor value,through the function calculates the corresponding oil quantity value. While retaining the previous sampling value, automated fuel management system to judge the speed of change the amount of oil consumption, realize the automatic detection of oil quantity in oil tank, non normal working state generate alarm.

Vane pump in step

1, the oil and gas separator filter plugging, oil pipeline is too long, too small to cause vane pumpload, produce noise; 2, vane type pump relief valve stuck open or adjusting screw adjustable too tightcause; 3, vane pump vane card dead, cause the fluctuation degree of oil output increased, so that the machine noise and vibration; 4 leaf spring (film), or damaged, resulting in gas machine noise increases; 5, the triangle with a too tight, so that the sliding bearing wear of vane pump, leading to the gas machine noise increases; 6, the machine in the vibration of the pipeline, the solution is to replace the quakeproof glue tube; inherent frequency pulsation frequency output 7, oil and gasmachine is similar, also will cause the oiling machine, vibration and noise increases. The solution isthe overflow valve to adjust the vacume pump or replace the oil gas, from the damping pad device and frame; 8, motor noise increases. The replacement of explosion-proof motor; angle loose bolts or other fasteners 9, fixed filling machine loose. Fasteners to the anchor bolts and other looseVane pump in step.

manual fuel transfer pump high head of water system

manual fuel transfer pump high head of water system, water supply system, pressure boiler water supply system, high purity water purification systems as well as medicine, food, fine chemical, paper making industry, washing, spraying process. Fuel pump and general stainless steel gear pump is different from the product with a pair of rotating gear in the pump body, an active, a passive, relying on two inter meshing gears, the fuel oil transfer pumps cavity of the whole work in two separate parts. Can transport oil, beverage, low corrosive liquid without lubrication oil pump. Copper gear manual fuel transfer pump can be equipped with a conveying low point liquid, such as gasoline, benzene and so. This series stainless steel gas fuel pump in common motor configuration, can also according to the configuration of explosion-proof motor with the specifications of the needs of users.

Fuel delivery action hand pump

fuel transfer hand pump action is to suck out the gasoline from the tank and fuel filter through line and pressure to the carburetor float chamber. Thanks to fuel pump, the fuel tank can be mounted to the rear of the car away from the engine, and below the engine.
Fuel pump driven by different ways, can be divided into mechanical drive diaphragm and electrically driven two.
Fluid pressure within the vessel by changing the way the human hand or a machine called a manual transmission fluid pump. Fluid pressure within the vessel by changing the way the human hand or a machine called a manual transmission fluid pump. hand gasoline pump, hand pressure pump, hand pressure pump, hand pressure fire pumps.

There are several dispenser

Marine fuel dispensers (Fabricated Fuel Rail), also known as the fuel rail or fuel rail, which is electronically controlled fuel injection system, the air / fuel subsystem part, it is a mechanical device, mounted on the intake manifold located spray at oil, its main function is to ensure the provision of adequate fuel flow and evenly distributed to each cylinder injector, while achieving installing and connecting each injector. In addition, it may have an impact on the fuel pressure pulsation, fuel vaporization temperature and the like.

Car fuel dispenser mainly used in diesel engines and gasoline engines, according to the processed materials can be divided into carbon steel, stainless steel, aluminum die-casting, injection molding several categories. According to the working pressure is divided into pressure and high pressure.

At present, the main fuel dispenser manufacturers produce stainless steel type. Because other types of material or process characteristics, almost all imports. (Also with an engine OEMs except their own production)

Note automatic tank gauge systems

automatic tank gauge systems in order to ensure the correct selection level gauge to better use. Choice of what kind of instrument should be based on the level of physical and chemical properties of the test to determine the fluid medium? Make level gauge diameter, flow range, lining materials, electrode materials and output current? Can adapt measured fluid the nature and flow measurement.
1, precision function tests
Accuracy classes and functions according to measurement requirements and use the occasion to select the instrument accuracy class, so economical. Such as for trade settlement, custody transfer and energy measurement products occasions, should choose higher level of accuracy, such as 1.0, 0.5, or higher level; process control applications for select different accuracy classes according to the control requirements; some only about the process flow is detected, without making precise control and measurement of the occasion, you can choose a slightly lower level of accuracy, such as 1.5, 2.5, or 4.0, then you can choose inexpensive plug-in level gauge.
2, measurable media
Medium flow rate measurement, the instrument measuring range and caliber of the media in general, the level meter full scale flow can be measured in the medium velocity 0.5-12m / s range selection, the range is wide. Select the meter size (diameter) is not necessarily the same process piping,fuel card management system should be considered whether the measured flow rate range within the range of flow rates to determine that when the pipe flow rate is low, can not meet the requirements of the flow meter or when this flow rate measurement accuracy can not be guaranteed, the We need to narrow instrument caliber, thereby increasing the flow rate of the tube to obtain satisfactory measurements

The basic principle of automatic level gauge system

automatic tank gauge systems in the measurement circuit is energized in the first instantaneous wire waveguide to produce an electrical pulse, the electrical pulse generates a circular magnetic field around the wire in the waveguide, the role of magnetic fields within the magnetic field and the float magnet in produce a small distortion on the waveguide wire deformation, this deformation along the waveguide wire to wire two moves when moving to pickup coil,ank level gauge systemdue to the magnetostrictive effect, will send out a weak magnetic field changes, the pickup coil onYou can detect this change in the magnetic field.
Since the distortion is a constant velocity along the waveguide wire movement, therefore, issue-driven electrical impulses from the beginning to pick up a change in the magnetic field experienced by the end of the length of time, showing the position of the float from the pickup coil, also reflects the high and low level , enabling accurate measurement of the liquid level.
