What empty running of screw empty press points to is to enter gas a powerful person to shut, but a powerful person that take energy of life has one alveolus to still be in into gas, the interior of the lube that assures pneumatics opportunity in order to keep constant pressure circulates normally. Still have certain load, cannot saying so is true empty running.

(1) the air inlet duct in dismantling engine of next screw type pneumatics, tear open next inlet valve and exhaust valve at the same time.
(2) open always receive water valve, adjust each refrigeration to pay tubal flow, pass inspect water implement observe whether each canalage current is expedite, it is normal that the examination indicates appearance each.
(3) start rare oily station to assist oil pump, adjust pressure to achieve formulary requirement.
(4) the turning number of pneumatics machine turns, affirm locomotive component is reached without abnormal noise shake a phenomenon.
(5) the instant starts motor, crankshaft of examination pneumatics machine changes direction correct. Stop machine of pneumatics of the examination after machine each component circumstance. If do not have unusual appearance hind, can undertake the 2nd times starting.
(6) 5min of the movement after be being started the 2nd times, check each component to have without overheat, vibration unusual wait for a phenomenon, discover the problem stops machine hind to should prove a cause, eliminate in time.
(After 7) is started the 3rd times, press into line space machine is no load locomotive mouth is no load locomotive time is 4 hours commonly.
2. is no load how should do when movement
(Unusual noise and vibration should be not had in 1) movement.
(2) lubricant system job is regular. Lube spends the regulation in according with product manual to be worth for oil pressure force, stannum.
(3) job of cooling water system is regular, water supply pressure, temperature should accord with the regulation in operation instruction handbook to be worth.
(Temperature of lever of piston of place of 4) filling flange does not exceed 1-O ℃ . Main shaft tile, connecting rod covers with tiles temperature does not exceed 5 Celsius.
(5) electromotor temperature, electric current should not exceed the formulary value in electromotor nameplate.
(6) job of equipment of electric, appearance is regular.
