First, an overview of LG, DL series pump vertical single-suction multistage centrifugal pump. The pump is installed vertically, the motor shaft and the pump shaft are connected by a flexible block coupling, which has the advantages of compact structure, low noise and small occupied area. For the transport of water or physical and chemical properties similar to the water liquid, mainly used in high-rise building water supply can also be used in water supply and drainage enterprises and mines, and low-pressure boiler cycle water. LG, DL medium temperature is less than 80 ℃, LGR, DLR medium temperature is less than 130 ℃ LG (R), DL (R) building feed pump Second, the model significance 65DL (LG) (R) 30-16 × 5 65 --- pump Import diameter 65mm DL --- Building Feed Pump 1450r / min LG --- Building Feed Pump 2900r / min R ---- Hot water type 30 --- Flow rate 30m3 / h 16 --- Single-stage lift 16m 5-- - Series Three, the performance range of flow: 1 ~ 200m3 / h Head: 16 ~ 260m Fourth, product characteristics LG, DL-type pump compared with the horizontal multistage pump, vertical multistage pump rotor with a smaller deflection, Therefore, smooth operation, small vibration, low noise, long service life, at the same time with a compact, small footprint, easy installation features.
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
