Diesel pumps are powered by diesel engines and are driven through an elastic coupling. These pumps feature an advanced and rational design, high efficiency, excellent cavitation performance, minimal vibration, low noise, smooth operation, and convenient installation. They are typically used in fire protection systems as backup main pumps, known as XBC diesel fire pumps. Additionally, they are suitable for industrial emergency applications such as boiler feed water and high-temperature feed water. The ZCSB model is specifically designed for agricultural irrigation in areas without a power supply.
These pumps are generally composed of a horizontal centrifugal pump, diesel engine, and electrical instruments, all mounted on a sturdy chassis. Control and signal lines are connected to the electrical cabinet for efficient operation. Before starting the diesel engine water pump for the first time, it's essential to check the installation of all components and follow the correct startup procedures.
First, fill the diesel engine and pump suspension with engine oil via the oil inlet and verify that the oil level meets the required height using the oil gauge. Next, add cooling water to the expansion tank, aiming to reach approximately two-thirds of the tank’s height. Fill the fuel tank with diesel and use the manual pressure pump to ensure the fuel passes through the filter and enters the system properly.
Connect the inlet and outlet pipes along with gate valves, and close the outlet gate valves, pressure gauges, and vacuum gauges. Ensure the pump and inlet pipes are filled with water and that any air inside is removed. Open the external circulating cooling water valve and, once the inlet valve is fully open and the outlet valve is closed, start the diesel pump. Once the diesel engine reaches normal speed, gradually open the outlet pipe valve and adjust the system to the desired operating mode.
The diesel pump is ideal for flood control, drainage, and sewage pumping. It features a self-priming capability, ensuring reliable operation even in challenging conditions. This model is particularly effective in handling large volumes of wastewater and is widely used in municipal and industrial applications. Its robust construction and efficient performance make it a preferred choice for critical operations where continuous and uninterrupted pumping is essential.
