The automatic control panel matched with the diesel water pump features strong environmental adaptability. It can withstand mechanical shocks, electrical interference, vibration stress, thermal loads, as well as the impact of humid environments that may occur under normal operating conditions.
I. Performance Specification of Automatic Control Panel
Upon receiving an external start signal in the form of a passive normally open contact, the control panel can automatically complete the startup of the pump set within 15 seconds. During the operation of the pump set, the control panel continuously monitors all operating parameters. Once a fault is detected, it will trigger an alarm signal in real time, and execute fault handling or protective shutdown in accordance with preset logic.
II.Preparations Before the First Startup
Before attempting the first startup of the diesel water pump, confirm that all equipment has been installed correctly, and complete the pre-start inspection following the steps below:
Engine Oil Filling
Fill engine oil of the correct grade through the diesel engine filler port and the pump bracket oil filler port respectively, then check via the dipstick to ensure the oil level reaches the specified scale mark.
Cooling Water Filling
Add coolant (clean water or antifreeze) to the diesel engine cooling system via the expansion tank, and keep the liquid level at approximately two-thirds of the total height of the expansion tank.
Fuel Filling & Air Venting
Fill the fuel tank with diesel fuel, then repeatedly press the manual fuel transfer pump to ensure diesel flows through the filter into the diesel engine, while venting all air trapped in the fuel pipeline.
Pipeline Connection & Valve Adjustment
Firmly connect the inlet and outlet pipelines together with gate valves to the water pump. Before startup, keep the gate valve on the outlet pipeline fully closed, and shut the cocks of the outlet pressure gauge and vacuum pressure gauge (if applicable).
Pump Priming & Air Venting
Fill the pump casing and inlet pipeline with water (or use a vacuum priming device), and completely exhaust all air inside the pump and pipelines.
External Circulation Cooling Water Turn-on
Open the inlet valve for the diesel engine’s external circulating cooling water to guarantee smooth circulation of the auxiliary cooling system.
III. First Startup & Operating Condition Adjustment
Start the diesel water pump set only when the inlet valve is fully open and the outlet valve is closed. After the diesel engine accelerates to its rated operating speed, slowly open the outlet pipeline valve. Meanwhile, monitor readings from the pressure gauge and flowmeter, and gradually adjust the pump to the required operating condition.
