Automatic lubrication pump works 
 The design requirements of the user according to the lubrication system, installed all the divider and piping connected to the power supply can boot oil. 
 1, the initial state 
 A system installation is good, this lubricating device power, oil-free jerry, jerry, low level switch is turned on, pumps oil to the lubrication pump jerry, the level rose to the highest Level, High Level Switch turn off pumps to stop refueling. 
 B, manual work status 
 The two main supply pipe and the distributor oil pipeline due to the beginning of oil, no oil, so the first change-over switch to switch in the state of the ongoing work to start the lubrication pump, a main oil pipeline oil through the valve to , when the pipeline is full of oil distributor spool action time, the pressure inside the tubes began to increase and promote the valve spool to another root of the main oil pipeline oil distributor spool once again the action , the pressure within the oil pipeline began to rise, to promote the reversing valve to the first root of the main oil pipeline oil supply, this back and forth, constantly changing the oil for lubricants to the lubrication points. Until the lubricating oil supply sent to all lubrication points, when the change-over switch to switch to the automatic state. 
 2, automatic working state 
 When the changeover switch honestly change in the status of the work automatically, the interval relay delay intervals equipment lubrication requirements set by the user (usually set at 3 to 5 hours), when the interval time delay to reach set given time, the lubrication pump is connected to a pipeline oil and the injection timing relay to work, to monitor the injection time, once all distributor oil, fuel end-of-pipe pressure began to increase valve began to change to another pipe oil supply. Same when all the distributor to complete the oil, the end-of-pipe pressure began to rise, reversing valve, pressure switch signals this time valve, lubricate the pump stops working, interval relay delay work. The system is a work readiness. 
 Electrical control part of the device with the oil leakage caused by extended time due to somewhere, overpressure, jerry waited in vain for fault alarm signal, the user can solve the problem according to the alarm signal point, to ensure that the system is in good working condition. The purchase of automatic lubrication pump, select the manufacturer of lubrication pumps to find Qidong Roewe lubrication equipment
