Hydraulic Station Testing Steps

1.Power On: Turn on the power to start the motor.

2.Main Pressure Adjustment: Hold the No. 1 relief valve spool and watch the main pressure gauge, ensuring it reads 8-10 MPa. If not, adjust the relief valve handle clockwise to increase pressure or counterclockwise to decrease pressure.

3.Activate Directional Valves:

Sequentially turn on the 1-9 electromagnetic directional valves. Once energized, oil will flow to the AB port, filling the cylinder with oil and causing it to operate normally. Note that longer oil pipes may delay cylinder action.

4.Flow Control:

Rotate the No. 4 knob to control the flow and adjust the cylinder speed. Clockwise rotation slows down the cylinder, and counterclockwise rotation speeds it up. Alternate the top of the No. 2 solenoid valve spool back and forth before adjusting the throttle valve to ensure smooth operation.

5.Pressure Adjustment:

Factory settings have each circuit pressure at 7 MPa. If adjustments are needed, rotate the No. 3 knob clockwise to increase pressure or counterclockwise to decrease pressure. Pressure adjustments should be done with the cylinder fully extended or retracted to show accurate readings.

Hydraulic Station Diagnostics

• No Cylinder Movement:

Solution: Check if the cylinder is full of oil. Run the cylinder back and forth a few times to expel air and initiate movement.

• One-Way Cylinder Action:

Solution: Check if the solenoid valve spool is properly energized and creating normal suction. If it is, ensure the relief valve is also energized. Verify that the top of the spool is adequately positioned with a 2mm elasticity, indicating that the solenoid valve is not stuck. Inspect the throttle valve to ensure it is not restricted; it should be open before and after the throttle valve for normal operation. Observe the pressure regulation—pressure will be displayed when the cylinder is fully extended or retracted, but not in the middle position. Adjust the No. 3 knob as necessary: turn clockwise to increase the pressure or counterclockwise to decrease it.

• Motor Clamping Issues:

Solution: Check if the solenoid valve spool is properly energized and creating normal suction. If it is, ensure the relief valve is also energized. Verify that the top of the spool is adequately positioned with sufficient depth, indicating that the solenoid valve is not stuck. Inspect the throttle valve to ensure it is not restricted; it should be open before and after the valve for normal operation. Observe if the motor is showing pressure. If there is no pressure, adjust the No. 3 knob as necessary: turn clockwise to increase the pressure or counterclockwise to decrease it. The motor should reach a pressure of 7-8 MPa to operate. If the pressure shows 8 MPa but the throttle valve is not fully open, ensure that the No. 1 solenoid relief valve is energized. Alternate the energization of the solenoid directional valve left and right a few times to ensure proper operation. Once the hydraulic motor reaches the correct pressure and the solenoid valve is not stuck, the motor should operate normally.

• Cross-Channel Actions(activating one channel also causes action in another channel):

Solution: If activating one channel also causes action in another channel (indicative of a stuck valve), alternate the top position of the electromagnetic directional valve spool back and forth. Check if the spool reaches the correct depth and has a slight elasticity of about 1 mm when in place. If the spool can normally achieve suction, it indicates proper function. If impurities have entered the solenoid valve, it can cause the valve to stick and fail to create suction. This issue, known as valve sticking or coil damage, requires cleaning. Unscrew the four screws to remove the solenoid valve and clean it thoroughly. Ensure the spool moves freely back and forth within the valve body. If it feels stiff, use fine sandpaper to smooth it and then clean with compressed air before reassembling.

(5)Stuck Valve with Pressure Indication:

Solution: Manually move the spool or clean the solenoid valve to remove impurities. Ensure the spool moves freely.

By following these steps and solutions, you can ensure the proper testing and operation of the ZMDE 4KW/9-channel Hydraulic Station. Regular maintenance and adherence to these instructions will help maintain optimal performance and longevity of the equipment.

3. Structure Principle, Adjustment, and Use

The machine is a roller conveyor high-performance shot blasting cleaning equipment. During the cleaning process, a speed-adjustable motor drives the conveyor rollers to send the workpiece into the blasting chamber. The workpiece surfaces are subjected to intense blasting from eight shot blasters from different spatial directions. The oxide scales and contaminants on the surfaces are quickly removed, and the surface obtains a certain level of roughness and brightness. The machine eliminates workpiece stress through intense impact, preventing deformation.

During the cleaning process, the mixture of shot and dust falls into the screw conveyor at the bottom of the chamber, which is then collected and lifted to the separator. Clean shots fall into the separator hopper, ready for reuse by the shot blasters. The dust-laden air is filtered by the dust removal system, achieving a dust removal efficiency of 99%.

This equipment consists of the following functional parts: main and auxiliary cleaning chambers, shot blaster assembly, conveying system, shot fall pipes, elevator, separator, shot conveying system, dust removal system, and electrical control system.

• Cleaning Chambers

(1) Structure

The cleaning chambers are composed of a main and auxiliary chamber. These are large cavity structures, with the upper part box-shaped and the lower part conical. Cleaning operations are performed within this sealed cavity, consisting of front and back auxiliary chambers, the main chamber, rubber curtains, protective guards in the shot blasting chamber, and shot blasters.

A: The main chamber has eight shot blasters installed at the top, bottom, front, and back. The spatial arrangement has been tested and proven to achieve optimal cleaning of the workpieces.

B: The cleaning chamber is a multi-chamber assembly, with both the front and back being sealed. It includes multiple layers of rubber curtains to prevent shot leakage and maintains a slight negative pressure to prevent dust from escaping.

C: Wear-resistant guards are installed inside the main chamber to protect the chamber walls from wear, significantly extending the chamber’s lifespan and utilizing the reflection of shots to continue effectively impacting the surface of the workpieces, thereby enhancing cleaning quality and efficiency.

D: The protective guards inside the shot blasting chamber are covered with wear-resistant nuts and are bolted on, protecting the bolt heads from damage and facilitating easy disassembly and replacement.

(2) Adjustment, Use, and Safety

A: The protective guards and cast nuts inside the shot blasting chamber are susceptible to wear and should be regularly checked for wear and replaced promptly. Care should be taken when installing the guards to ensure overlapping, preventing damage to the chamber walls and ensuring safety.

B: The rubber curtains inside the cleaning chamber are prone to wear and should be repaired or replaced promptly if damaged, to prevent the escape of shots and dust.

C: During operation, personnel should stay away from the chamber entrances and exits to prevent shot splatter into the eyes, and warning signs should be hung.

D: When entering the cleaning chamber for maintenance, the power must be disconnected in advance, warning signs hung, and powered operations are strictly forbidden as they could endanger personal safety.

• Roller Conveyor and Conveying

(1)Structure

• The workpiece conveying system consists of a roller conveyor powered by a cycloidal pinwheel reducer, which has a strong load capacity.

(2)Adjustment and Use

• Adjust the speed of the conveying system from slow to high, gradually based on the cleaning effect on the workpieces, to achieve a high-quality cleaning effect and good economic performance.

• Shot Blasters

(1)Structure

• The shot blasters consist of an impeller, blades, a directional sleeve, and an inlet pipe. Shots are fed into the distributor wheel through the inlet pipe, pre-accelerated, and then ejected through the mouth of the directional sleeve, with the blades continuing to accelerate them to high speeds to forcefully impact the workpieces for cleaning.

Adjustment and Use:

• A: To adjust the shot projection zone, first close the shot gate, place the workpiece in the projection area, stop the roller conveyor, ensure safety, then open the shot blaster, manually introduce a small number of shots into the shot pipe, and after the shot blaster stops, pull out the workpiece to check if the striking position is appropriate. Adjust the directional sleeve up or down as needed.
• B: Uneven wear on the impeller can cause severe vibration in the high-speed running shot blaster. Check the condition of the blades before each shift and replace them if they show deep grooves or are worn more than half. Blades must be replaced in symmetrical pairs, and the weight difference between two blades should not exceed 5 grams.
• C: Check the ammeter readings on the shot blaster; they should indicate the appropriate shot flow.
• D: Do not open the shot blaster’s cover while it is still moving or while the power is not completely disconnected.

• Elevator

(1)Structure

The machine features a flat belt-driven bucket-type elevator, with the housing welded into shape, used to lift the mixture of shots and dust from the lower spiral conveyor to the top of the machine.

A: The elevator uses large pulleys to increase friction, with the lower wheel being cage-type to prevent sand, slipping, and misalignment, ensuring smooth and reliable belt operation and effectively extending the belt’s lifespan.

B: If the belt in the elevator slips during operation, adjust the tensioning device or check for overload.

• Separator

(1) Structure and Principle

The separator is a BE-type curtain structure. The shot-dust mixture is evenly fed into the separation area by the feed screw conveyor, forming a uniform curtain of shot-dust, which passes through a 4-5 m/s horizontal airflow for shot-dust separation. Shots and waste materials are separated based on their specific gravity, with clean shots falling into their respective channels; after passing through a grid, they enter a hopper for use by the shot blasters, while fine dust is drawn into the dust removal system, and the purified air is discharged into the atmosphere, capturing particulate dust.

(2)Adjustment and Use

A: Adjusting the gap of the separator’s tongue plate can control the uniform distribution of the shot-dust curtain, achieving optimal separation effects.

B: The separator’s outlet and the dust removal system’s pipe connection have an airflow adjustment gate, which must be adjusted to an appropriate position to ensure that usable shots are not lost to the waste bin.

C: Qualified shots passing through the separator’s screen effectively prevent larger objects from entering the hopper, ensuring the safe operation of the shot blaster.

• Spiral Conveyor

(1)Structure

A spiral conveyor and shot fall chute are located under the cleaning chamber to collect the mixture of shots and dust, which is then sent to the elevator and on to the separator. They consist of a cycloidal pinwheel reducer, spiral shaft, housing, and bearing seat.

(2)Adjustment and Use

A: After installation, the spiral conveyor shaft should rotate flexibly without any jamming.

B: Excessive shots in the spiral conveyor trough can increase the starting torque, leading to equipment failures. Issues should be promptly resolved, and large quantities of shots should not be added to the collection hopper at once but rather introduced slowly.

• Shot Conveying Pipes

The shot conveying pipes have a dual function, each gate tube is equipped with a gate plate for adjusting the flow of shots and facilitating maintenance. The opening and closing are controlled by an electromagnetic valve below.

• Dust Removal System

The dust removal system mainly consists of dust removal pipes, a pulse cartridge dust collector, fans, and air ducts. The dust removal efficiency of this system is 99%, achieving high dust removal performance. The air containing dust can be directly discharged into the atmosphere after dust removal, without the need for purification equipment. This complies with the “Comprehensive Standards for the Control of Air Pollution” (GB16297-1996) and the “Industrial Standards for the Emission of Waste” (GBJ14-93).
