The positive displacement pump has a side clearance adjustment member (4) for moving a shaft (3) to the rotor (1) side or a side separated from the rotor (1) when rotating with respect to a pump main body (6).;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPITOGURA TADAHIRO...
DRAWING UP THE EVOLUTION PEDIGREE OF THE POSITIVE DISPLACEMENT PUMP MACHINE AND THE CREATIVE DESIGN——REVIEWING THE PAST HELPS ONE TO UNDERSTAND THE PRESENT The positive displacenent pump machine that produces periodical change of a closed volume can be designed to be an internal combustion engine,...
Rotary positive displacement pumps draw fluid into some type of chamber, which is then moved around by the rotary action of the pump from the inlet to the outlet of the pump, where the fluid is discharged. The clearances between the moving parts are typically close, so the pump spe...
The structure of the pump is mainly composed of pump body, active and passive screw, shaft seals, bearing frame device, synchronous gear, safety valve and other components (see structure schematic drawing). There is no thread in the middle of the active a...
When drawing liquid through a suction a pump generates a low pressure in the suction area, which, if it reaches vapour pressure, gives rise to gas coming out of solution and causing bubbles to form. An estimate of the margin above vapour pressure, used for many years, is Net Positive Suct...
2.after your company approved drawing ,we will make quotation. 3. final we make agreement on payment terms ,delivery time ,package ,shipment etc. 10.how about your company after-sale serivce ? 1. We provide long-term after-sale service. 2. we can do...
Negative pressure systems are commonly used for drawing materials from multiple sources to a single point. There is little or no pressure difference across the feeding device and so multiple-point feeding into a common line presents few problems. As a consequence, the feeding device can be a ver...
5. Is it available to print our own brand on the pump? Totally acceptable as international rules. 6.Can you make according to customer require? Yes, we can make according to your sample or drawing, OEM/ODM service provided. 7.What is your packing?
(as viewed in the drawing) is mounted at a different angle than the right side pump, thus in this embodiment the pumps operate at different flow rates, as may be desirable for example for two primers applied to a windshield. The pumps may alternatively be run at the same flow rate. In...
The drawing depicts a spray apparatus, including the paint pushout apparatus of this invention, for applying a two-component paint. The color resin is fed through color valve 7, through metering pump 4, through line 2 into spray gun 1, while at the same time the clear crosslinking agent ...
