VP500B with power showed in Diagram 4-4. As the simplest design, it could be installed at end of reclaiming pipe, namely, near to tank and inlet. It can simultaneously reclaim 12 nozzles, applicable to fuel dispenser with suction pump or submersible pump. Center-type reclaiming vacuum pump VP500B without power showed in fuel dispenser Diagram 4-5. This type of pump is very applicable to city filling station, which is powered by submersible pump, mounted 8 nozzles of reclaiming. The deployment of vapor pipe and air vent of tank ensures station’s normal operation. Distributed reclaiming vacuum pump: each fuel dispens fuel dispenser er is mounted vapor reclaiming vacuum pump. Diagram 4-6: VP vacuum pump Diagram 4-7: Separated jointer Diagram 4-8: Coaxial hose Separated jointer: its main function is used as convert jointer to separate vapor and oil. Repeated use breakaway: used for protecting fuel dispenser in case of pull down by vehicle. As exterior pull reaching 310~350lb, breakaway is automatically closed, at same time switch off pipelines of vapor and oil. Coaxial hose: a kind of hose with two layers that delivery vapor in internal and exterior oil. Nozzle: with double-layer pipes, mounted vapor valve. Fuel dispenser with vapor recovery system This kind of fuel dispenser with vapor recovery function is used for reclaiming volatile oil vapor near outlet without affecting normal refueling. There are two types widely adopting in domestic market, one is the new developed fuel dispenser that has vapor recovery f fuel dispenser unction; the other type is improved fuel dispenser based upon traditional dispenser and added vapor recovery function. Generally, these are divided into two categories: submersible type and built-in pump type. Diagram 4-9: Vapor recovery nozzle Submersible fuel dispenser with vapor recovery function If adopt vacuum-aid vapor recovery system, the matching fuel dispenser with vapor recovery function should adopt submersible fuel dispenser. Its working principle is that center vacuum pump g

BASE　　This part of the document details the standard data organisation for a car wash.　　Every data element in the car wash database is described in this chapter. The access to the　　data element is done by a database address DB_Ad and a data identifier DataID.　　The data elements are presented in the following form:　 fuel dispenser 　 DATABASE　　 DB_Ad =　　 DataI Field Type ReadWrite MO　　 Data Element Name　　 D fuel dispenser in State　　 Description　　The DataID is a unique identifier for a data element in a database. The database is defined by　　the database address DB_Ad (for details see document Part II Communication　　Specification).　　In the second column the name of the data element is defined. In this column is also the　　description of the data element.　　The field types in column three are described in IFSF Engineering Bulletin No. 11.　　The ReadWrite in State column indicates if the related data can be Read andor Written by　　any device and in which CWP state (states are indicated between brackets).　　The MO column (MandatoryOptional) indicates if the data element must be supported　　implemented by the CWP s and any CD controlling Washing Points. M indicates that the　　data element must be supported; O indicates that the data element is optional.　　Note: All mandatory data eleme fuel dispenser nts must be supportedimplemented for a device to be IFSF　　compatible.　　3.1 Database Address　　Every data element in a device is stored in a database. In some implementation it may be real　　database or only a software organisation (object or tasks) for instance if a separate processor　　manages each washing point.　　These database levels are addressed by the Database Address (DB_Ad) using a variable　　number of bytes.
