Small electric truck manufacturers talk about the common sense of the hydraulic system of the truck

We will take into account many factors when choosing a truck on a daily basis, such as: performance, price, brand, etc. Among them, the common sense and attention points of small electric truck manufacturers in the selection of solenoid valves for trucks are very worthy of our attention. Then, let's talk about the reliability and applicability of the hydraulic system of the truck.

I. Reliability
1. Solenoid valve is divided into normally closed and normally open. Closed; but small electric pallet truck manufacturers should remind everyone that the normally open type should be used when the opening time is very long and the closing time is very short.
2. The solenoid valve has no waterproof function, please choose the waterproof type under necessary conditions.
3. When the action time is very short and the frequency is high, it is recommended to choose the direct-acting type, and the quick-acting series for large diameters.
4. In addition, small electric truck manufacturers also recommend that the high nominal pressure of the solenoid valve must exceed the high pressure in the pipeline, in order to prevent shortened service life or other accidents.
5. In the environment with corrosive liquid, all stainless steel type should be used; strong corrosive fluid should use plastic king solenoid valve.

II. Applicability
1. The fluid in the pipeline should be the same as the medium calibrated in the selected solenoid valve series, and the small electric The truck manufacturer reminds everyone that the temperature of the fluid should be lower than the calibration temperature of the solenoid valve.
2. The allowable liquid viscosity of the solenoid valve is generally below 20CST, and if it is greater than 20CST, it should be indicated.
3. The power supply current and power consumption should be selected according to the output capacity. Generally, the power supply voltage is not allowed to be about 10% plus or minus. It must be noted that the VA value is relatively high during AC starting.
4. When the maximum pressure difference of the pipeline is less than 0.04MPA, direct-acting and step-by-step direct-acting types should be used; when the low working pressure difference is greater than 0.04MPA, a pilot-operated (differential pressure type) solenoid valve can be selected; The differential pressure should be less than the maximum calibrated pressure of the solenoid valve.
5. When the cleanliness of the fluid is not high, a filter should be installed in front of the solenoid valve. Generally, the solenoid valve requires better cleanliness for the medium. Small electric pallet truck manufacturers remind everyone to pay attention to the flow aperture and the diameter of the nozzle. The solenoid valve is generally controlled by only two switches. If conditions permit, please install a bypass pipe for easy maintenance.

The above is the relevant content about the reliability and applicability of the hydraulic system of the pallet truck brought to you by the small electric pallet truck manufacturer. I hope it can be helpful to everyone when choosing a truck in daily life.
