We are the leader of 15 years experiences and guarantee Based on "the Interim Regula tion of Lawyers of the People's Republic of China"(issued in 1980), the All China Lawyers Association (ACLA), founded in July of 1986, is a social organization as a legal person and a self-disciplined professional body for lawyers at national level which by law carries out professional administration over lawyers. All lawyers of the People's Republic of China are members of ACLA and the local lawyers associations are group members of ACLA. At present, ACLA has 31 group members, which are lawyers associations of provinces,fuel dispenser Fuel dispenser Partsautonomous regions and municipalities and nearly 110,000 individual members.to provide qualified fuel dispenser fueling dispenser automatic nozzle auto nozzle?pumping unit?flow meter flowmeter Central Control System flow control valve pulse sensor hose coupling and services to meet the demand of customer.

Let K, The hydraulic section of fuel dispenser is a comprehensive presentation of the applied hydrodynamics, mechanical manufacturing, engineering mechanics, engineering material, automotive control principle and metrology. The performance of hydraulic components and matching ration is symbolic of fuel dispenser. This chapter mainly introduces the structure of hydraulic components, working principle and troubleshooting of fuel dispenser, such pump, oil-air separator, measurement transducer, nozzle, oil indicator and solenoid valve. Since there are many brands of fuel dispenser that mounted different hydraulic parts it is difficult to comprehensively introduce domestic fuel dispenser's hydraulic components. In order to facilitate the reader to better understand hydraulic components and master maintenance technique, this handbook will present the popular fuel dispenser's structure, working principle and reparation methods. Despite different model of components there are still many similarities in their working principle. To learn the common components is conducive to know other model. As a failure phenomenon occurred by various causation, only deeply understand products one can precisely judge its trouble. Therefore, we spend a whole chapter to introduce the working principle of components. In fuel dispenser market there are many hydraulic parts with similar appearance and inner structure. Different manufacturers with different research and understanding provide various products in terms of performance and failure presentation. Readers could maintain not only according to the User's manual provided by manufacturer, but also analyze and repair to the knowledge introduced in this chapter. Professional maintenance operator assigned by manufacturer will be asked when meeting some much difficult trouble. The hydraulic source system of fuel dispenser composes of pump and motor. By delivery model it divides positive delivery and negative delivery. The former model adopts submersible pump, usually a centrifugal pump that be installed in oil; in some regions and mount areas adopts high bracket tank, to refuel through oil gravity. Under these two situations the inlet oil pressure of fuel dispenser is larger than atmospheric pressure. The latter model adopts volume pump --- often gear pump or vane pump, installing inside of fuel dispenser together with motor. A certain vacuum pressure occurs at the inlet of fuel dispenser when fueling. Fuel dispenser mounted submersible pump, its pump being inside of tank with low noise, has large room to facilitate design many nozzles. The negative pressure fuel dispenser, however, has the benefit of convenient maintenance and low price of whole system. At recent, as negative pressure one prevails in market, the article mainly introduce this kind of fuel dispenser. Negative pressure fuel dispenser normally selects a ration cubage pump. In order to ensure adjusting flow rate there is a bypass valve connected with pump in juxtaposition. When refueling fuel dispenser's discharge capacity is controlled by the return volume of bypass valve that, of course, ensure the hydraulic system security of fuel dispenser. This kind of bypass valve generally is overflow valve that is closed down while fuel dispenser dot work, and always open as fuelling. The return volume of overflow valve is changed by fuel dispenser's flowage. Pump is a key component. Its performance is measured through the following aspects: suction capacity, reliability, noise and stability. Of date, some manufacturer put pump and oil-air separator into a common frame, but some install these elements respectively. Some people in circle call pump and oil-air as pump source. Pump's performance only relate to its structure design and manufacturing level, not the connection of components. The handbook, therefore, introduce by the category of pump, not by the connection of oil-air separator. 1. Vance pump It is also called rolling broad pump. Tanks to less weigh than gear pump and column plug pump, high pollute-resistant, simple structure, low cost and convenient maintenance, vane pump is widely adopted in many industrial areas. Most of domestic manufacturer of fuel dispenser install vane pump as component. Vane pump includes ration pump and variable pump, the former is mounted in fuel dispenser. At recent years, the domestic noise research for vane pump has been achieved good progress conducted by fuel dispenser manufacturer. The noise of vane pump has remarkably been downed, reaching to less than 70 d B. it is introduced as followed: The Diagram 2-1 and 2-2 illustrate one kind of vane pump about its structure and tridimensional exploded drawing. This kind of pump prevails in domestic fuel dispenser market. Its structure, principle and maintenance will be introduced. Vane pump consists of overflow valve and vane pump illustrated in Diagram 2-1. Overflow valve is installed on the upper of body, including overflow valve seat, vale core, spring, spring bracket, jointer, adjusting bolt and cap nut. The lower body is pump section composed of gliding bearing, rotor subassembly, blade set, spring flat and pump cover with gliding bearing. The right side of diagram is inlet, the opposite outlet. The working principle, performance and common troubleshooting of vane pump and overflow valve will be presented respectively. ? Vane pump section The chamber in where rotor installed is pump chamber, its installing procedure showed in diagram 2-3. A centrifugal degree e between the center of chamber and rotor is illustrated in diagram. There are upper and down seal area, high pressure and low pressure transitional area, divided by the center of rotor. The angular degree in sealing area is larger than that of degree formed by the neared two vanes so as to prevent oil flow between low and high pressure areas.rate, one will reduce openness of nozzle so as to increase the outlet pressure of pump. In that case, openness of valve and returned oil increase due to overflow valve work on spring, the outlet flowage of fuel dispenser is lessened. When the pressure of hydraulic system in fuel dispenser is suddenly increased due to some cause, overflow valve overcome spring strength under high pressure, raise openness and returned oil flowage to reduce pump pressure and protect the hydraulic system. Clockwise turn adjusting bolt of overflow valve given the openness of nozzle is unchanged the flux of fuel dispenser will be increased; anticlockwise turn decrease flux. 1.2 Performance of vane pump 1.2.1 Suction capacity Like other pump the good performance of vane pump should has high suction capacity, excellent stability with less vibration, small transitional volume, low noise, nice reliability and maintainable. These traits depend upon rational structure design, right selection of material and manufacturin Suction capacity of pump is restricted not only by its structure but also by the oil physical trait and pipeline. Under a certain temperature, air pocket phenomenon of oil will generated when vacuum reaching a given degree, so that the pump can't suck oil normally. At high oil level, large resistance from pipeline, much higher vacuum pressure occurs at the inlet of pump; the higher temperature the more likely create air pocket. The phenomenon is likely to appear given the oil is gasoline. The phenomenon of cavitation is generated when partial pressure at inlet of pump is low than air pressure, the dissolved gas in oil begin separate out, and oil start gasifying than Strife would seem to be contrary to na hongyangword1hongyangword2hongyanggroupcopyright
