Instructions for installation and use of hydraulic power unit of ordinary environmental protection vehicle

Date of release:2019-06-16 Author: Click:

1. Fix the hydraulic power unit in an appropriate position.

2. The thread of the main valve plate connected with the pipe connector is: M16*1.5.In addition, several tees are respectively connected with the rising and falling oil ports of two oil cylinders, which are connected with high-pressure hoses.

3. Fill the tank with anti-wear hydraulic oil (summer # 46, winter # 23).

Connect the power supply.Motor 380V, three-position four-way solenoid valve 24V.

Action process car lift power unit

1. Ascending or forward movement

Start the motor, three - way solenoid valve solenoid coil control the rising end to get electricity, until the desired elevation.The motor and solenoid valve lose power, and the oil cylinder is in the rising position, holding the pressure.

Step down or step back

Power off the motor, the other end of the three-position four-way solenoid valve power, the oil cylinder to achieve the drop, until the required position.Motor, solenoid valve, action completed.

Three, travel speed adjustment

Below the three-position four-way solenoid valve is a double one-way throttle valve, if the speed needs to be adjusted, the handle can be rotated to slow down.Instead, accelerate.

The motor of the hydraulic power unit of the lifting machine is started, the coil at the rising end of the three-position four-way solenoid valve is energized, and the oil cylinder is raised.(if not rising, the other end of the coil can be charged) reach the specified position.The single oil cylinder rising is powered by two two-way check valve coils and then rising.Reach the designated position, the rise action is complete.

Three-position four-way solenoid valve down control one end of the coil to get electricity, double-acting cylinder down.(double-acting oil cylinder rising and falling motor must be in working state, it is driven by hydraulic oil to achieve action)

Single-acting oil cylinder drop is a two-way check valve with a manual solenoid valve at the same time to achieve electricity.(at this time the motor can be closed, it is on the deadweight oil road connected to the drop) as a single oil cylinder, which know which two-way check valve connected to work.When the rise does not need to be accompanied by manual solenoid valve electrified, when the fall must be accompanied by manual solenoid valve electrified.

Double-acting oil cylinder speed control

This system has a double one-way throttle valve, which can speed the travel speed.Slow forward spin, fast reverse spin.The system normally takes less than two minutes to implement with one action.During debugging, do not work for more than two minutes.After a few minutes of discontinuous action, there is no impact on the system.

This product has been tested and adjusted before delivery. The pressure has been set. Please do not adjust it again to avoid damage to the motor.

The first use of hydraulic oil half a year to replace, after a year to replace.
