Henan rubber lined pumps, 2pnjb rubber lined pumps, Yongchang Pump (certified merchants)

Rubber lined pump works with the same outer recirculation pump rubber lined rubber lined pumps 2pnjb, the difference is not just backwater flow impeller outer edge, and the flow of the impeller inlet. Within a mixed-type self-priming centrifugal rubber lined at startup pump impeller return valve must open before the bottom, so that the liquid flows back to the pump impeller inlet. Of water at high speed rotation of the impeller is mixed with the role of the air intake pipe to form a gas-water mixture is discharged to the separation chamber. Here the water and from the air exhaust recirculation valve returns to the impeller inlet. This is repeated until the air is drained, smoking Sheung Shui. Rubber lined pump self-priming height Chenjiao pump manufacturers, and the impeller clearance before sealing, the number of revolutions of the pump, the separation chamber liquid level and other factors. Impeller before sealing the smaller the gap, the greater the height of self-absorption, and generally 0.3 to 0.5 mm; in the gap increases, in addition to a high degree of self-absorption decreased, the pump head, the efficiency decreased. Pump self-priming height u2 with the peripheral speed of the impeller increases, but when the maximum height of self-absorption, while increasing the number of revolutions of self-priming height is no longer increased, but this time the self-priming time shortening; when the number of revolutions When dropped, the height of self-absorption, along with the decline. In other conditions remain unchanged, the height of self-absorption also increases storage height increases (but not exceed the height of the separation chamber optimum storage). In order to better enable self-priming pump gas and water mixing impeller blades to be less, so that the pitch of the cascade increases; and should adopt the semi-open impeller (or impeller wider channel impeller) rubber lined pumps This is more convenient to return to the penetration depth of the impeller cascade. Pipeline pump centrifugal pump chemical pump magnetic pump pump rubber lined pumps 2PNJB Chenjiao big advantage 1. Since rubber lined pumps 4PNJB 4PNJFB smooth flow channel, flow resistance is small, and therefore available to a larger traffic. 2. rubber lined body cavity surface pump 2PNJB look complex has a variety of rubber Office alternative. Therefore, have superior corrosion resistance characteristics. 3 rubber lined pumps 2PNJB. Enclosed piece of flexible rubber diaphragm. It also has a good tightness and minimum closing force ...
