Return self-priming pump
I. Overview
ZXB back flow from the pump, is the digestion and absorption of the advantages of similar products abroad, mapping and improved design,
Compact structure and reasonable, and the production of precision.
Part of its self-priming pump ZXB pump body materials, are acid-resistant stainless steel (the international standard for the AIS1316),
Acid corrosion properties, particularly, in line with food hygiene requirements.
Superior to the characteristics of centrifugal pump is to draw on a mixture of liquid air or foam, and even the air in only when the same self-suction, the pump is positive displacement pump.
This pump is widely used in liquid level below the pump to draw in missing materials, such as in the breast pump, the milk from the milk can be sucked in barrels, or CIP automatic cleaning system, as the cleaning tank return pump, mechanical seal for the contents within the flow, the temperature of the liquid to draw no more than 80 ℃.
Second, the main technical parameters and performance
CHENG Yang-way flow of suction impeller diameter material import and export track speed-power
(T / h) (m) (m) (mm) (mm) (kw) (r / min)
3-8 3-4 18 150 40-50 1.1-1.5 1420 304 or 316L
15-20 3-4 20 190 50 4 1420 316
Third, performance, structure Description:
By the flow - lift curve (QH), we can see that the head with the flow increases. In addition, another feature of the pump is self-priming ability, a test report from analysis of the vacuum suction and flow, close to the relationship between direct proportion.
The self-priming pump is installed in the general conditions, the inhalation of high (including air) for 3 m, if in some occasions the need to further improve the inhalation of a high, then the installation should pay attention to the suction pipes as short as possible, pump suction valve should be avoided as far as possible doors, elbow, and three links. Discharge tube 1 m in vertical height, the pump outlet in a vertical 1 m, the middle bend is not set, then the pump can be the greatest height of 5 meters inhalation (available with air)
Self-priming pump from the pump cover, impeller, pump body, clamping ring, the motor of the stars of radiation-shaped impeller, pump cover and pump body cavity pump comprising, when the impeller in the cavity in the rotary pump, the impeller radiation cavity volume and the composition,
I play by the inhalation of increasing to the exit row, and gradually reduce the volume of the composition. Therefore, spoke impeller contained in liquid, can be pumped into a liquid and the reciprocating action, a certain self-absorption capacity.
Pump in contact with the materials the main materials used are high-quality stainless steel 316L, the other components of the demolition of the structure of easy, user-friendly cleaning. |
