branded advantages

Dasheng brand has passed the ISO9001-2008 and ISO13485-2012 quality system certification of TUV, Germany, and is a national industrial product production license manufacturer approved by the General Administration of Quality Supervision, Inspection and Quarantine of China has obtained EU industrial CE, EU medical CE certification, and American food FDA certification issued by the Drug Administration.

Features and advantages

1. Ultra-quiet: The sound of the reciprocating compressor is extremely low when it works, which can meet the requirements of all indoor applications.

2. Ultra-clean: Dasheng DA7002 reciprocating compressor is pure oil-free design, unique oil-free lubricating piston system, high efficiency, low loss, ultra- clean exhaust gas, which meets the needs of supporting equipment and ensures the safety of operators. More in response to the global call for "green environmental protection".

3. Anti-rust spraying: The interior of the gas storage tank is treated with anti-rust and anti-bacteria to ensure the cleanliness of the gas and the safety of the product from the source.

4. Low energy consumption: The pressure and gas production ratio is based on the golden ratio, which can quickly produce the most gas sources under the condition of low energy consumption, and the start and stop of the air compressor are automatically designed, which not only saves electricity, but also saves worry.

5. Core technology: Cylinder liner system specializes in the development of nano-coating technology, abandoning the oil-free materials commonly used by ordinary manufacturers, making it quieter, cleaner, and longer-lasting, adapting to higher-demand fields, such as the food and pharmaceutical industries.

6. Safe use: Dasheng air compressors are equipped with multiple automatic protection systems. Any abnormality in the operating environment, such as voltage, air pressure, or current, will automatically shut down the air compressor to ensure the safety of equipment and personnel.

7. Easy to operate: ready to use when connected to electricity, automated design, work without special personnel on duty; air pressure can be adjusted freely according to the requirements of use, without complicated maintenance, only regular drainage.

Principle of reciprocating compressor

Due to the round-trip movement of the piston, the air enters the compressor through the filter, and then the air is compressed, so that the compressed gas enters the air storage tank by opening the check valve through the metal hose through the exhaust port. The pressure gauge pointer display rises to 0.8Mpa. When the pressure is greater than 0.8Mpa, the pressure switch automatically shuts off, the motor stops working, and at the same time, it is emptied through the solenoid valve to reduce the pressure in the compressor cylinder to 0. At this time, the pressure of the air switch and the gas in the air storage tank is still 0.8Mpa. When the gas is discharged through the ball valve, the pressure in the air storage tank drops. When it drops to 0.5Mpa, the pressure switch automatically turns on and the compressor starts working again.

Principle

The reciprocating compressor belongs to the miniature reciprocating piston air compressor, and the single-axis motor drives the crank- rocker mechanism with a staggered angle of 180°. The main kinematic pair is a cup-type piston ring, and the auxiliary kinematic pair is a cylindrical surface of aluminum alloy with a protective layer. There is no need to add any lubricant between the kinematic pairs due to the self-lubrication of the piston rings. The compressor makes the stroke volume Due to the single-axis double-cylinder structure, when the motor rotates once, each group of cylinders will have a secondary direction. Contrary to changes in cylinder stroke volume. When the piston travels toward the shaft, there is a negative pressure in the cylinder. At this time, the atmospheric pressure is greater than the pressure in the cylinder, and the air enters It is compressed, and the pressure increases rapidly. When the pressure is greater than the pressure acting on the exhaust valve, the exhaust valve is opened, which is the exhaust process. The single-shaft and double-cylinder structure of the compressor makes the displacement of double that of the single cylinder, and the vibration due to the crank-rocker mechanism with a staggered angle of 180° makes the first-order inertial forces that affect the vibration of the compressor cancel each other out, so that Vibration and noise are improved, and the overall structure is more compact.

Maintenance

1) The reciprocating compressor is an oil-free air compressor, and it is strictly forbidden to add any lubricating oil.

2) During the use of the DA7002 reciprocating compressor, the water should be drained and the silencer filter should be cleaned every one to two days.

3) If the reciprocating compressor stops suddenly and cannot be restarted within a short period of time (the voltage is normal), it may be because the drive motor has been working for a long time and the motor is overheated, and the motor thermal protector automatically cuts off the power to protect the motor. It is a normal phenomenon, when the temperature drops, the compressor will start automatically and continue to work.

4) The reciprocating compressor cannot start normally. Please check whether the power supply is normal and whether the power plug is in good contact. If these are normal, the motor itself or the control system may be faulty.
