ZH-type vane adjustable side mounted vertical axial flow pump, is the company based on market demand and the use of self-developed a new product. The pump is a liquid axial flow pump along the axial direction of the pump, characterized by large unipolar flow, lift range, high efficiency, applicability, water or physical and chemical properties of other liquids similar to water. Pumping small investment, high reliability, no vibration, low noise, etc. Widely used in urban water supply and drainage, industrial transport circulating water, irrigation and drainage and other aspects of agricultural irrigation.
Structural features:
1, the pump directly connected with the motor through the motor support, looking down from the motor direction, the pump rotates clockwise.
2, the water pump axial thrust into a unit of internal force, not delivered to the foundation, greatly reducing the design load requirements of the basic strength.
3, pump installation, maintenance is very convenient, no intermediate transmission shaft.
4, the pump seal in the form of double-ended mechanical seal, almost no leakage, it runs smoothly.
5, all over-current components are made of high quality materials (316), effectively improve the anti-cavitation pump performance. Can transport 0 ~ 180 ℃ all kinds of strong corrosive media.
Precautions:
The pump in use, in addition to pay attention to the "general water pump" has the precautions (such as heavy pressure, blow and other external forces), but also pay attention to:
1, check the pump before running the rotation direction is correct, the pump is flexible operation;
2, pump in operation if found to have abnormal noise, they should immediately check the reasons;
3, the pump running at normal speed, and gradually open the outlet gate valve, until the required flow, lift so far, the pump in the long run, should be run within the specified performance range in order to obtain the best results;
4, the leakage of mechanical seals is not more than 10mL / h;
5, the pump in operation, the bearing surface temperature does not exceed 60 ℃, temperature does not exceed 35 ℃;
6, after long-term use of the pump, when the flow pressure dropped significantly, it should conduct a celebration of the inspection, timely replacement of worn parts, reduce unnecessary losses.
