Rawsun Standard model
High reliability, low noise, high safety lightweight, small volume, double insulation design, high protection level
Rawsun Dual power model
In case of failure of high voltage, it will automatically switch to low-voltage power supply mode to ensure the continuous normal operation of the booster pump.
The product is small in size, light in weight and high in power density.It has the functions of monitoring, self-diagnosis and protection of input and output state and other parameters, such as overtemperature automatic downgrading, overcurrent, short circuit, reverse connection, pre-charging circuit, voltage detection, current detection, internal circuit self-diagnosis, CAN bus diagnosis, etc.
Scope of applications
Rawsun steering pumps are wisely apply for electric minibuses, big buses, electric buses, electric trucks, electric sanitation, electric cargo trucks, etc. Wide coverage: power from 1kW to 4kW, can cover all electric vehicles steering power requirements.
1. The steering pump assembly shall meet the requirements of QC/T 299 “Technical Conditions for Automobile Power Steering Pump”;
2. Mechanical drive impact is not allowed when the assembly is working;
3. Measure the noise at 1000mm from the front of the assembly. In no-load operation, the working noise of the assembly is less than 65dB;
4. The stay time of the steering wheel when it turns to the limit position is not allowed to exceed 10S, and the system does not allow the shutdown phenomenon of overcurrent protection;
5. There is a reliable grounding protection wire interface on the surface of the motor, which must be effectively grounded after installation;
6. The steering machine shall be equipped with a stroke unloading valve, and the stroke opening pressure at the limit position of the direction shall be less than 5MPa;
7. During wiring, the phase sequence corresponds to the position of the plug-in. At this point, from the direction of the pump head, the motor rotation direction is counterclockwise (left rotation), whereas the motor rotation direction is opposite and the steering pump does not work.
8. Working environment temperature: -40℃+80℃;
9. Clean appearance, no foreign matter, dirt, damage and other defects, good bonding surface between the assembly and the parts, no air leakage, no oil leakage and other phenomena;
10. Add dust cover to the inlet and outlet to prevent pollution during transportation and storage;
11. The foot shall install the shock cushion with the assembly.
