Dry oil centralized lubrication systems mainly come in two forms: single line and double line.Process lubricationThe system has two oil supply lines, which use solenoid valves for reversal. The reversal signal comes from a differential pressure switch or a pressure controller. The lubrication system consists of a lubrication pump, a fuel pump, a solenoid valve, a liquid level switch, a differential pressure switch, a distributor and other components. composition. The configuration of the model varies. The single-line lubrication system has only one oil supply line, which supplies oil to the lubrication point through a multi-stage single-line distributor. The electrical control box of the dry oil lubrication system is suitable for most signal dry oil lubrication systems. The electrical control box can set two times to control the monitoring time and interval time, and perform regular monitoring of the oil supply of the A and B pipelines respectively. , if the pressure cannot be achieved within the predetermined time, it is regarded as oil leakage in the pipeline. The oil supply of two pipelines A and B is one oil supply cycle. The time from the completion of one fuel supply cycle to the next fuel supply cycle is the interval time. Monitoring time can also be defined as working time to achieve regular reversal.

Using a single-chip microcomputer as the control system, the input signal is processed at high speed according to the requirements and then the processed signal is output to control the action of the actuator. The work of the microcontroller is controlled by software, and the functions of the control system are 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 microcontroller is divided into two parts: the main electrical part and the operation panel. Eight-digit LED tubes are used on the operation panel to display the monitoring time, interval time and working status respectively. The monitoring time is 1 second to 99 hours, 59 minutes and 59 seconds, and the interval time is 1 second to 99 hours, 59 minutes and 59 seconds, which can be adjusted at will. Each function key on the panel adopts a touch key, making the system beautiful and elegant. The electrical control box of the dry oil lubrication system has three working modes: continuous operation, remote control, and manual control. You can choose one of the working modes according to your needs. It also has protection functions such as overload.
