Diesel pump set, also known as emergency diesel pump set, is often used for emergency water supply when the cooling circulating water in the factory is cut off. At room temperature, the water quality can be clean water. The pump driven by diesel engine can be started automatically in case of power failure to prevent high temperature burning of industrial boiler and effectively ensure normal water supply.

As a standard, the diesel pump set is equipped with unmanned intelligent system. The emergency diesel pump set has the characteristics of advanced technology, high automation, perfect performance protection, reasonable structure, simple installation, high cost performance and so on. Automatic inspection of diesel pump full intelligent control; automatic program control; automatic process control; automatic data collection and display; automatic fault diagnosis and relay protection. Direct digital control of diesel pump, complete information display. The operation status of emergency diesel pumping unit includes: waiting, starting, oil supply, starting, starting delay, idling delay, normal operation, cooling shutdown and emergency shutdown.

The operation parameters display of diesel engine pump set includes: pump speed, pump head, cooling temperature, lubricating oil pressure, pump flow, operation time, fuel oil inventory, starting battery voltage and other parameters. The protection settings of diesel engine pump set include: overspeed, low speed, low oil pressure, high cooling temperature, low temperature (below 4 ° C), low oil level, low battery voltage, high battery voltage, uncalibrated speed signal and low diesel oil pump pressure pre alarm, such as overcurrent, no speed signal, overspeed, low speed, low oil pressure, high cooling temperature, start failure, shutdown failure, open / short oil pressure sensor Circuit, water temperature sensor open / short circuit, speed sensor open / short circuit, pump water pressure automatic alarm, such as low flow and over flow.

The original mechanical and electrical integration design of diesel engine pump in China, users only need to connect the water inlet and outlet pipes and exhaust pipes to work, and the diesel engine emergency pump group with communication interface can be directly connected with the control center to realize "four remotes" (remote regulation, remote communication). Cation, remote monitoring, remote control) monitoring and operation records; original domestic bottom oil tank, low level automatic drain pump for emergency start. Actions are effectively assured. The original water-cooling structure of diesel engine pump realizes the cooling of engine system through water / water heat exchanger and specially designed air / water air cooler (turbocharger type application). Equipment installation is not limited by space and area, which can effectively improve the efficiency of the same engine by 7% - 10%. Save investment cost directly for users.
