Brief description of the working principle of the screw pump

1. The single-screw pump is a volumetric pump with internal rotation eccentrically rotating. The main components of the pump are: a single-screw rotor and a stator with a double screw which is usually made of elastic material. When the rotor is in the cavity When planetary rotation is performed around the axis of the stator, the closed wrist formed between the rotating stators is displaced along the rotor spiral; therefore, the medium is continuously, evenly, and constantly delivered from the suction inlet to the extrusion end. This feature, single-screw pump is particularly suitable for the following working conditions.

2. Delivery of high-viscosity media: According to the size of the pump can be transferred from 37000-200000 centipoise media.

3. Medium containing particles or fibers: The particle diameter can be 30mm ( no more than rotor eccentricity ) . The fiber length can be 350mm ( corresponding to a pitch of 0.4 rotor ) . Its content is generally up to 40% of the medium pit , and if the solid matter in the medium is a fine powder, a high content of 60% or more can also be transported.

4. It is desirable to use a single-screw pump for conveying when the delivery pressure is stable and the inherent structure of the medium does not like damage.

Air Supply System for the spray paint room operating area by the temperature, humidity, filter clean fresh air equipment. The amount of air flow depends on the size of the wind in the painting room. The size, temperature, humidity and dust removal of the painting room depend on the type of paint sprayed, the appearance quality of the coating and the working environment of the operator. Paint room Typical air conditioning air supply system: bird fence (air inlet) â†’ suction adjustment blinds â†’ pre (early) filter â†’ preheater â†’ washing section and retaining plate â†’ after heater â†’ fan â†’ after filter â†’ Muffler â†’ air conditioning shutters. According to the different needs of users, air conditioning system can have more than the composition of different segments. They are installed in a channel-type body made of galvanized steel. Because the air volume is bigger, only has the heating heating function, because the summer reduces the temperature to consume the energy and the investment is big, generally does not have the cooling device, does not have the cooling function. Heating heat source for hot water, steam, electricity, fuel oil, thermal oil, natural gas. In the northern winter, the outdoor temperature dropped to -20 â„ƒ the following occasions, can be installed in the suction nozzle of natural gas combustion, direct heating, sandstorms in the large area of the inlet can be added sand filter. In the south, the green environment is good, less sand and high humidity occasions, in order to save investment, can be saved washed section. Water section of the sink, wall panels made of stainless steel, the supply of water quality is better. In the filter before and after the general installation of a pressure gauge, when the pressure reaches a certain value should be replaced when the filter element. The filter element is made of a non-woven filter material. Generally from the plant outside the suction, suction outlet in the strong wind when the sand and dusty places, away from the paint room exhaust outlet a little farther or in the wind at the side, the suction outlet should be installed metal mesh or fence to prevent inhalation of birds . In order to prevent the fan noise into the paint room, in the fan after the air duct should be muffler.

Fan size According to the size of the spray booth and the number of ventilation to determine the number of hours of air supply unit for the spray booth hours per hour and the volume of indoor ventilation product. Temperature, humidity and degree of dust removal depends on the spray paint varieties, coating quality requirements and appearance of the operator's operating environment.
