What are the characteristics of the hydraulic system of the electric hydraulic pallet truck?

In the past, when choosing an electric hydraulic truck, a lot of consideration was taken, such as: performance, price, manufacturer, etc. Among them, the electric pallet truck manufacturer selected the solenoid valve for the battery truck Knowledge and focus are worthy of our attention. Then, let's talk about the reliability and usability of the hydraulic system of the truck.

1. Choose a reliable one.

1. The solenoid valve of the electric hydraulic truck is divided into normally closed and normally open. Our standard configuration is the normally closed type. The manufacturer of electric pallet trucks should remind everyone that the normally open type should be selected when the closing time is slightly shorter during use.

2. The standard configuration of the solenoid valve has no waterproof function. Please select a battery truck equipped with a waterproof solenoid valve if necessary.

3. The direct-acting type is suitable for the work intensity with high frequency of action and long working time, and high-speed series is selected for large specifications.

4. In addition, the electric pallet truck manufacturer also recommends that the high pressure in the hydraulic pipeline should not exceed the high nominal pressure of the solenoid valve, which is to avoid the shortening of the service life of the pallet truck or the anything unexpected happens.

5. If you are transporting corrosive goods, you should choose an all-stainless steel electric hydraulic truck with strong corrosion resistance, and choose a corrosion-resistant solenoid valve.

Second, the selection of applicability

1. The fluid in the pipeline should be consistent with the medium specified in the selected battery truck solenoid valve series standards, and Electric pallet truck manufacturers will recommend that the heat of the fluid is second only to the calibration temperature of the solenoid valve.

2. The allowable liquid viscosity of the solenoid valve is generally less than 20CST, and it should be stated if it exceeds 20CST.

3. The battery current and power consumption of the pallet truck should be selected according to the output capacity. Generally, the power supply voltage is not allowed to have a positive and negative difference of 10%. Be alert to the high VA value when the AC is started.

4. When the high pressure difference of the hydraulic pipeline of the electric hydraulic truck is less than 0.04MPA, the direct-acting type and the step-by-step direct-acting type should be used; when the low pressure difference is greater than 0.04MPA, the pilot type ( Differential pressure type) solenoid valve; the high working pressure difference should be less than the maximum calibration pressure of the solenoid valve.

5. When the fluid purity of the hydraulic system of the battery truck is not high, a filter should be installed in front of the solenoid valve. Generally, the solenoid valve needs better cleanliness for the medium. Electric pallet truck manufacturers recommend that you pay attention to the flow aperture and the diameter of the nozzle. Generally, the solenoid valve only needs to be controlled by two switches of the switch. If conditions permit, please install a bypass pipe for easy maintenance.
