A pump or air compressor is required to move hydraulic fluid through the system. Both achieve this goal and through different methods of operation. The pump can move liquids or gases. Due to the natural compressibility, compressors usually only deliver gas. Pumps and compressors have high pressure rises.

In general, the characteristic curves given by the Plastic Pump manufacturer mostly refer to the characteristic curve when conveying clean cold water. With the power pump, as the viscosity of the liquid increases, the head and the efficiency decrease, and the shaft power increases. Therefore, in the industry, the liquid having a large viscosity is sometimes heated to make the viscosity small to improve the conveying efficiency.

The traditional cordless paint sprayer uses compressed air to atomize the paint. The spray speed of the paint is generally 10 m / s. Such a fast spray speed leads to overspray and severe rebound of the paint, and brings back a large number of paint molecules. The paint is scattered, which not only wastes a lot of paint, but also causes serious pollution to the air, and the surface of the coating is prone to smashing.

The cordless paint sprayer is sprayed, and the oil quantity is not easy to be controlled. The spraying effect is not uniform, resulting in large oil consumption. The machine can carry out multiple spraying at one time, and the shape and oil quantity and uniformity can be controlled.

When the oil-free compressor is installed in the field, it can be judged that the compressor rotates in the correct direction according to the decrease of the suction pressure and the increase of the exhaust pressure. In addition, if the refrigeration compressor is reversed, the compressor noise is abnormal and the operating current is significantly lower than normal operation.

Inspect the China glue gun for signs of damage. Before inserting the power supply or using the applicator, carefully inspect the applicator and check for signs of cracking, chipping, or any other damage, and see if the wires are worn or broken.
Make sure that the nozzle has no old glue. There should be a clear melt path at the tip of the glue gun. If necessary, remove the nozzle, wipe with aluminum foil, remove the dry glue, or use a toothpick to clean the hole.

1. After each spraying, pour the thinner/day water into the watering can and spray it clean until the spray coating channel is clean. Do not put the China spray gun into the water or thinner. The result is Damage to the seal assembly inside the gun, resulting in reduced gun performance or direct use;
2. The spray gun should not be cleaned with a steel ball-like cleaning tool. Which brush should be used for cleaning to avoid nozzle and atomizing cap wear;
3. When appropriate, the spray width, paint adjustment button, etc. can be removed to wipe off some lubricating oil to ensure smoothness during mediation.

The oil-free compressor industry chain includes upstream supply of various types of steel, copper rods and copper and zinc. Midstream compressor parts manufacturing, such as blades, balance blocks, cross-ring connectors and other accessories and compressor assembly, and downstream The compressor is applied to other fields such as household electric appliances. Among them, the midstream compressor parts are the core of the entire industrial chain, and it is the key part to determine the technical level of the whole machine.

oil lubricated compressor can be divided into low back pressure type, medium back pressure type and high back pressure type according to the application range. Low back pressure type (evaporation temperature -35 ~ -15 °C), generally used in household refrigerators, food freezers, etc. Medium back pressure type (evaporation temperature -20 ~ 0 °C), generally used in cold drinks cabinets, milk refrigerators, etc. High back pressure type (evaporation temperature -5 ~ 15 °C), generally used for room air conditioners, dehumidifiers, heat pumps, etc.
