What cooling kind does screen pump have?

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The screen pump that is a major produces manufacturer. When type selecting of client screen pump, manufacturer of my company water pump can provide the before-sales service such as price of pump of screen pump model, screen, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge that has what cooling kind about screen pump:

       The circular liquid action inside screen pump has two, it is cooling electric machinery and bearing; 2 it is lubricant bearing is taken away wear away child. The kind of going from place to place that presses circular cooling fluid is different, screen pump can divide for the following 3 kinds:
Screen pump circulates inside 1. . Lubricate to be in what pump interior circulates to be with cooling fluid body inside circularly. The screen pump of this kind of type, the liquid that lubricates to be carried namely with cooling liquid to bearing. Circular liquid does not make pump housing outside, 2 use hollow axis to form close loop. Because do not try to cool to circular fluid, consequently, suit to carry normal temperature liquid only.
2. outer circulationScreen pump. Lubricate to make pump housing with cooling fluid body exterior, via circulating the canal flows into electromotor to be in those who undertake circular to be outer circulation. Those who press circular means is different can divide again it is two kinds;
1) direct cooling, namely from pump exit derivative one carries a liquid, undertake circular cooling, refrigeration hind returns entry point again. Means of this kind of loop, be carried by its liquid temperature, still can divide for two kinds of structures:
A. When carrying liquid temperature to be less than 50 degrees, electromotor does not take a snake to be in charge of condenser, from pump exit derivative liquid lubricates directly bearing and cooling electromotor
B. When carrying liquid temperature to reach 100 degrees in 50 degrees, electromotor contains a snake to be in charge of condenser, circular fluid is exported from pump derivative, after via the snake the canal is cooled, undertake lubricating to bearing, cooling electromotor.
2) alone refrigeration, its loop cooling fluid is carried by auxiliary impeller, become separate circulatory system oneself, electromotor sets a snake to be in charge of condenser (or special heat exchange unit) . This kind of type is commonly used spend prep above at carrying fluid temperature 100 degrees high temperature circumstance.
Pump of 3. mixed cycle screen. The combination with outer circulation means circulates inside.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction that has what cooling kind about screen pump, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company still produces fire pump, welcome you at any time seek advice.
