All oil-free Air Compressor Dasheng DA7003 Power 2250w

Introduction

Oil-free Air Compressor is a device that provides air source for pneumatic equipment. As a general-purpose mechanical equipment, it is widely used in various industries. Due to different industry applications, there are also differences in types, such as screw type, piston type, etc. This DA7003 oil-free Air Compressor is a piston type oil-free Air Compressor. Through the reciprocating movement of the piston, the air pressure is generated and sent to the air In the tank, a pure oil-free design is adopted to prevent gas pollution and be environmentally friendly and energy-saving.

Dasheng DA7003 oil-free Air Compressor is a piston Air Compressor with 3 pump heads and a power of 2250w, which belongs to the standard series. The air storage tank of DA7003 oil-free Air Compressor has been treated with internal anti-rust treatment, and the volume is 90L. Dasheng brand has 19 years of production experience in the field of oil-free Air Compressors, and has obtained FDA, CE, ROHS, and ISO900 and 13485 certifications from Nande Company. Oil-free Air Compressors are widely used by domestic (CN) and foreign laboratories and are reliable. Good sex, professional and environmentally friendly.

Product Structure

Features

1. Ultra-quiet: The sound of the oil-free Air Compressor is extremely low when it is working, which can meet the requirements of all indoor applications.

2. Ultra-clean: The machine is pure oil-free design, unique oil-free lubricating piston system, high efficiency, low loss, ultra-clean exhaust gas, meets the needs of supporting equipment, ensures the safety of operators, and responds to "green environmental protection" global call.

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 ratio of pressure and gas production is based on the golden ratio. Under the condition of the least energy consumption, the most gas source can be produced quickly, and the start and stop of the Air Compressor are all automatically designed, which not only saves electricity, but also saves you 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: Dashengquan oil-free Air Compressors are equipped with multiple automatic protection systems, which automatically shut down when any abnormality such as Voltage, air pressure or current occurs in the operating environment 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.

Product real picture

Compressor Principle

The oil-free Air Compressor belongs to the micro-reciprocating piston-type oil-free Air Compressor, and the single-axis drive of the motor is a crank rocker mechanism with a 180 ° distribution. The main motion pair is a leather bowl piston ring, and the paid motion pair is a cylindrical surface with a protective layer of aluminum alloy. There is no need to add any lubricant between the motion pairs due to the self-lubrication of the piston ring. The oil-free Air Compressor makes the stroke volume of the cylinder change periodically through the swing of the crank rocker and the reciprocating motion of the conjoined piston. Due to the single-shaft double-cylinder structure, when the motor rotates once, each group of cylinders will have a change in the stroke volume of the cylinder in the opposite direction. When the piston travels to the shaft, the cylinder is under negative pressure. At this time, the atmospheric pressure is greater than the pressure in the cylinder. Air enters the cylinder through the intake valve. At this time, it is the suction process. When the piston travels to the cover, the gas entering the cylinder is compressed, and the pressure increases rapidly. When the pressure is greater than the pressure acting on the exhaust valve plate, the exhaust valve is opened. At this time, it is the exhaust process. The structure of the compressor's single-shaft double-cylinder makes the compressor's exhaust volume double that of the single cylinder. The crank-rocker mechanism with a wrong angle of 180 ° makes the first-order inertial force that affects the vibration of the compressor cancel each other, so that the vibration and noise are improved and the overall structure is more compact.

Principle of the whole machine

Due to the reciprocating 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 from the exhaust port through the metal hose, and the pointer of the pressure gauge rises to 0.8 Mpa, when the pressure is greater than 0.8 Mpa, the pressure switch is automatically closed, the motor stops working, and at the same time, it is evacuated through the solenoid valve to reduce the pressure in the compressor cylinder to 0. At this time, the pressure of the gas in the air switch and the gas storage tank is still 0.8 Mpa. When the gas is exhausted through the ball valve, the pressure in the gas storage tank will drop. When it drops to 0.5 Mpa, the pressure switch will automatically open and the compressor will start again. Work.
