As past over long service time, parts abrasion universally or cylinder severely damaged, a new measurement transducer should be installed to replace old one. As find exterior leakage, firstly inspec fuel dispenser t the bolts corresponding to leak section. Tightly screw loose bolts, if leakage is continued, disconnect and inspect the seal ring and gasket relative section. Substitute aging or damaged parts and reassemble. Apart from the above reasons of extensive colloid and surface abrasion, these trouble also cause abnormal operation of measurement transducer, such as position pin fall down from piston or deformation, small axis lost on upper and lower connecting rod, loose bolt between piston and connecting rod. The solution is that disassembling measurement transducer, replace damaged or unqualified components and reassemble. The products made in normal factory seldom appear these troubles. Since measurement transducer is core component of fuel dispenser, elaborate machining, disconnection and reassembly should be as careful as possible. All elements should be cleaned before reassembly, excluding water into inner. Bolts are tightened even and appropriately. Soft-piston measur fuel dispenser ement transducer As these merits --- small in size, light weight, beautiful appearance, high accuracy, piston exchangeable--- soft- fuel dispenser piston measurement transducer is widely adapted in domestic fuel dispenser market. It generally involves two structures: four-piston structure and double-piston structure. The latter model is selected universally. Therefore, this article will introduce the structure, working principal and maintenance of four- piston measurement transducer. Structure Diagram 2-20 and Diagram 2-21 show the cutaway view and exploded drawing of four-piston measurement transducer that is widely employed. The transducer mainly consists of sealed cover, upper subassembly, export axis, frame subassembly, piston subassembly, connecting rod and top cover, clearly presenting in Diagram 2-20 and Diagram 2-21.

cines and vaccines will come from companies not governments. Reputable ones will not put their work at risk in places without proper regulations. Doing the right thing can strengthen the BWC, and ma fuel dispenser ke commercial sense too. © 2006 .  About sponsorship Health and the haj Life, death and pilgrimage Dec 13th 2006 From The Economist print edition Pious travel is always a brush with mortality—but some risks can be reduced AFP NEARLY seven years ago, a middle-aged lady called Rashida travelled from her home in England to Saudi Arabia on the haj, the journey to Islam s holiest places which every Muslim is urged to make at least once. As her six children recall, she returned in a state of “radiance and exhilaration� thrilled to have accomplished the pilgrimage for three years in a row. But within a few days, she fell ill and died of a virulent type of meningitis known as W135; she had been vaccinated for two other strains, but not that one. As custom dictates, she was buried fuel dispenser in the ihram or simple white tunic that she, like any other pilgrim, had worn in Mecca. The haj, which will bring over 2m people fuel dispenser to Mecca towards the end of this month, has always been a somewhat perilous undertaking, and pilgrims� like devout travellers of every faith and era—see facing the dangers of the road as part of their spiritual duty. But the gathering in Mecca presents some unique challenges although there are Hindu sites which attract even greater numbers, there is no sacred spot which compares to Mecca in drawing together people from so many different places for such a short, intense, intimate time. In ages past, the journey to and from Mecca often Arafat the joys and risks of took several months; in the era of air travel, the pilgrim can be there and proximity back in eight days. But there are always some
