Vertical high temperature hot water circulation pump working principle is:
Vertical high temperature hot water circulation pump so can send the water is due to the effect of centrifugal force.Pump before work, pump body and feed line must be tank filled with water to form a vacuum, when the fast rotating impeller blade promote water quickly spin, spin the water under the action of centrifugal force, fly away from the impeller and pump in the water, after being thrown at the center of the impeller part form the vacuum area.Water in the original water at atmospheric pressure (or hydraulic) through the pipe network pressure under the action of the feed water pipe.So circulates, can achieve continuous pumping.
It is worth mentioning here: before starting the centrifugal pump must to the pump shell full of water, can start, otherwise will cause heat pump body, vibration, water yield reducing, damages to the pumps (hereinafter referred to as \"cavitation\") cause equipment accident!
Vertical high temperature hot water circulation pump products overview:
1. The pump is vertical structure, import and export of diameter is the same, and in the same center line, like valve installed on the line, compact appearance beautiful, cover an area of an area small, low construction investment, such as plus a shield can be placed in the outdoor use.
2 installed directly on the extension of the motor shaft, impeller, short axial dimensions, compact structure, the pump and motor bearing reasonable configuration, can effectively balance the radial and axial load of pump operation, so as to ensure the smooth operation of the pump, small vibration, low noise.
3, adopting the combination of mechanical seal or mechanical seal shaft seal adopts imported mechanical seal and sealing ring, medium, high temperature resistant titanium alloy using hard alloy material, wear-resistant sealing, can effectively extend the service life of mechanical seal.
4, convenient installation and maintenance, do not need to open pipe road system, as long as the discharge of couplet of pump rotor nut can be pulled out all the parts.
5, can be used according to the requirements of flow and head need to adopt pump series, in parallel operation mode.
6, can be adopted according to the requirements of piping layout of vertical and horizontal pump type installation.
Vertical high temperature hot water circulation pump product use:
1, the vertical pipeline centrifugal pump for conveying water or other liquid with similar physical and chemical quality Yu Qingshui, applicable to industrial and urban water supply and drainage, pressurized water supply in high-rise building, garden sprinkler irrigation, fire pressurization, long-distance transmission, hvac refrigeration cycle, cold and hot water circulation pressurization in the bathroom, etc, and form a complete set of equipment, using T temperature of 80 ℃ or less.
2 (high temperature), vertical hot water circulating pump is widely used in: energy, metallurgy, chemical industry, textile, papermaking, and hotels such as boiler high temperature hot water pressurization circulation and urban heating system cycle pump, which use temperature < T < 120 ℃, GRG type use temperature 240 ℃.
3, vertical pipeline chemical pump for conveying not containing solid particles, corrosive, similar to water in the liquid viscosity, suitable for petroleum, chemical industry, metallurgy, electric power, papermaking, food, pharmaceuticals and synthetic fibre etc, using temperature is 20 ℃ ~ + 120 ℃. -
4, vertical pipeline oil pump for conveying products such as gasoline, kerosene, diesel oil, temperature of medium to be delivered - 20 ℃ ~ + 120 ℃.
