Q:What is the high and low pressure circuit of diesel engine?

High pressure oil from the pump to the diesel engine combustion chamber nozzle before that, due to the movement of the piston engine in the process of pressurized environment into the combustion chamber of diesel oil injection so the pressure is high, the combustion chamber is higher than the minimum compression pressure environment stroke made, otherwise the oil can not be sprayed into the combustion chamber. So this section of the road is made of metal.

Q:HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?

The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.
