Application characteristics and maintenance methods of diesel engine mobile pump truck
The diesel engine mobile pump truck is an intelligent control product, and the operation information is displayed in informational information. The running status display of diesel engine mobile pump truck includes: waiting, starting, fuel supply, starting, starting delay, idling delay, normal operation, cooling shutdown, emergency shutdown. The display of equipment operating parameters includes: water pump speed, water pump head, cooling temperature, lubricating oil pressure, water pump flow, running time, fuel stock, starting battery voltage and other parameters. Equipment protection settings include: overspeed, low speed, low oil pressure, high cooling temperature, low air temperature (below 4°C), low fuel level, low battery voltage, high battery voltage, uncalibrated speed signal, and water pump water pressure is too low and over Flow and other pre-alarms; no speed signal, overspeed, low speed, low oil pressure, high cooling temperature, start failure, shutdown failure, oil pressure sensor open/short circuit, water temperature sensor open/short circuit, speed sensor open/short circuit, water pump water pressure over Automatic alarm for low and over flow;
When the diesel engine mobile pump truck is working, the diesel engine water pump relies on the high-speed rotating impeller, and the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. Before the centrifugal pump works, the pump body and the inlet pipeline must be filled with liquid medium to prevent cavitation. When the impeller rotates rapidly, the blades make the medium rotate quickly, and the rotating medium flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. While continuously inhaling liquid, it continuously gives the inhaled liquid a certain amount of energy to discharge the liquid. The diesel engine water pump just works continuously like this.
How to maintain the diesel engine water pump? In fact, as long as you do this, the life of your product will be much longer than others.
Maintenance method of diesel engine mobile pump truck:
(1) Regularly check the boom of the mobile drainage pump truck, and check every weld as much as possible. If there is cracking or desoldering, remedy it immediately.
(2) Check whether the diesel oil, engine oil, cooling water, transfer case oil, and rotating motor oil are normal.
(3) Check the hydraulic oil level. If the oil level is low or lower than this level after the outriggers and booms are deployed, fill the hydraulic oil immediately. When filling, pay attention to the cleanliness of the oiling equipment, and there should be no sand or sundries.
