Automatic tank gauge systems delivery pipe to the points to ensure continued

Fuel pump high-pressure fuel delivery pipe to the points to ensure continued supply of fuel to the injectors. Fuel pump and the engine running when you start work, if the engine stopped and the ignition switch is still turned off the fuel pump control module power, fuel monitoring system in order to avoid accidental ignition. Vehicle fuel tank fuel pump located inside the fuel pump by an electric motor, pressure limiter, check valves and electric motors in the actual work in the fuel pump housing, do not worry, because the shell does not have any thing to ignition, fuel can lubricate and cool pressure side fuel motor oil outlet check valve at the air-pressure pump limiter is tank level gauge system located in the shell, with access to the inlet channel.In modern cars used in a variety of fuel injection system, fuel supply means they are different, but must be safe with an electric fuel pump. Its main task is to supply enough fuel system and there is a certain pressure fuel. Due to the mechanical fuel pump diaphragm by structural constraints, installation fuel management software location away from heat both fixed-line and also can not be tapped installed. The electric fuel pump location can be arbitrarily chosen, and have no air resistance characteristics.The control voltage of the electric fuel pump lead to the armature winding. Electric fuel pump casing at both ends of curling clench, so that all parts are assembled into a non-removable assembly.

First determine the system design goals and functional requirements

Design automatic tank gauge systems, first determine the system design goals and functional requirements, feasibility analysis on the technical and economic point of view, and then select fuel management systems the program and the overall design, consider the lower computer hardware circuit structure is reasonable, cost and other issues, explore the functional framework the host computer, the details of the data structures used, then the detailed design and debugging, the final completion of the design task. In the initial design, the main consideration of the following factors:
(1) reliability. Automatic tank gauge systems is safe and reliable, stable performance, long-term continuous tank level gauge systemoperation in harsh environments.
(2) versatility. At design time, you should take full account of their common application objects, the automatic tank gauge systems has a strong versatility, can promote the use of depot.
(3) compatibility. The fuel monitoring system should be able to carry different types of sensors linked to, a variety of parameters can be measured.
(4) economy. Reasonable economic cost of the automatic tank gauge systems, high cost performance.
(5) ease of operation and maintenance. On the software side, requiring friendly interface, easy to operate; hardware, easy maintenance and overhaul requirements. Tank area parameter settings and modify: the number of storage tanks, label set communication parameters, storage tanks partition management definitions.

Oil tank monitoring system with large flow meter can be used

Table correction dedicated tank level gauge, with large flow meter can be used as gas stations and tanker most important product - fuel oil, its reserves, the loss will be directly related to the economic interests of the gas station pump, and tank volume table accurate or not oil tank monitoring system they will determine whether the oil station can be improved inventory control. Domestic oil tank monitoring system is currently used mostly for one-time and long-buried put to use, in the course of running the inevitable deformation, tilt and other phenomena, so that the tank volume table with the factory when there are oil tank monitoring system some errors.The main work of calibration of vertical cylindrical tanks is to determine the retail fuel dispensers radius of the circle plate. The main method of current confining gauge method, capacity comparison method, optical plumb method, optical reference line method and optical triangulation method, each method is closely related with the oil tank monitoring system tool, the ultimate goal is to determine the radius of the circle plate. With the oil tank monitoring system improvement tank automation system of processing mode, new measurement tools of mathematics, we can expect a new calibration method will emerge.Removing the fuel system in any of the components, the fuel system must first release the pressure within the system in order to avoid pressure oil spray.
