Dry oil centralized lubrication systems are mainly available in single and double lines. The process lubrication system has two oil supply lines, which use solenoid valves to commutate. The commutation signal comes from a differential pressure switch or a pressure controller. And other components. The configuration of the model is different. The single-line lubrication system has only one oil supply line, and supplies oil to the lubrication point through a multi-stage single-line distributor. The electric control box of the dry oil lubrication system is suitable for most of the signals of the dry oil lubrication system. The electric control box can be set for two times to achieve the control of the monitoring time and the interval time. If the pressure cannot be reached within the predetermined time, the pipeline is considered to be leaking oil. The oil supply of the two pipelines A and B is a fuel supply cycle. The interval from the completion of one fueling cycle to the next fueling cycle is the interval. The monitoring time can also be defined as the working time to realize timing commutation.

The single-chip microcomputer is used as the control system, and the processed signals are output after high-speed arithmetic processing on the input signals according to requirements to control the action of the actuator. The work of the one-chip computer is controlled by software, the function of the control system is determined by software. The contacts of signal sensors such as differential pressure switches and liquid level switches are powered by low-voltage DC, without AC220V voltage, and work stably. The electrical control box of the single-chip microcomputer is composed of a main electrical part and an operation panel. Eight-bit LED tubes are used to display the monitoring time, interval time and working status on the operation panel. The monitoring time is from 1 second to 99:59:59, and the interval time is from 1 second to 99:59:59. Each function key on the panel adopts touch keys, and the system is beautiful and generous. The electric control box of the dry oil lubrication system is provided with three working modes of continuous operation, remote control and manual control, and one of the working modes can be selected according to the needs. It also has protection functions such as overload.
