(1) hose in a mobile or stationary, and can not bend over, it can not be bent at the root, at least to start bending at 1.5 times its diameter;
(2) hose moved to the extreme position not pull it too tight, should be more relaxed;
(3) try to avoid the hose twisting deformation;
(4) hose as far as possible away from the heat radiating member, fashion necessary insulation boards;
(5) Avoid hose external damage, such as the use of the same long-term friction surface of the member;
(6) If the hose caused by excessive weight deformation, should support members.
Pre-installed piping
1 Introduction pipeline
(1) two-director and branch Gas Control Valve: From lubrication pump out until all the oil inlet distributor, relatively high under pressure. Usually cold drawn seamless steel gas heater valve, the material is 10 or 15 gauge steel. Severe corrosion of the pipe must not be used;
(2) to the pipeline: from the distributor to all lubrication points out the inlet (bearing hole), under pressure is relatively low. Usually drawn copper, easy to bend when the gas heater control valve. There is also cold drawn seamless steel or stainless steel pipe;
(3) the use of hose fittings encountered active site connections.
Piping layout requirements
(1) gas heater valve to try to avoid the heat radiation and cooling water temperature is too high or too low, such as spraying of the Department, particularly hose fittings;
(2) piping and other equipment should not affect the operation of the host, to be safe, reliable, easy to work, observations, maintenance;
(3) To smooth vertical and horizontal piping, neat appearance. As little as possible, or small-angle bend elbows, using a large arc, thus reducing oil flow resistance;
When the conflict (4) installation occurs, a small tube let bassoon, low-pressure Gas Heater Control Valve so that high-pressure pipe;
(5) the pipeline can not be contacted at the intersecting should spaced;
(6) parallel pipe joints should be staggered installation, to avoid affecting the installation and removal;
(7) In order to facilitate disassembly pipeline cleaning, the union should be properly installed, but to use less, reducing the possibility of leaks.
