PRODUCT DETAILS

Type 2 cy gear pump is suitable for conveying containing no solid particles and fibers, non-corrosive, temperature is not higher than 80 ℃, the viscosity of 5 x 10-6-1.5 x 10-3 m2 / s (5 to 1500 CST) the nature of the lubricating oil or other similar oil liquid and used for hydraulic rotation system.

High temperature gear pump is essential equipment for polyester melt transportation, pressurization and melt measurement.Heat pump more than any other type of melt pump compact structure, reliable operation, low energy consumption, high volumetric efficiency and the effect on the melt shear small, flow stability in high viscosity and high pressure, outlet pressure fluctuations.The unique advantages of the pump and its key role in the process make it play an irreplaceable role in polyester production.

A complete gear pump comprises a motor, a reducer, a coupling, and a pump head, which consists of a pump housing, a front and rear cover, a gear shaft, a sliding bearing, and a shaft seal.The high temperature gear pump belongs to the positive displacement pump, which relies on the change of working volume caused by the meshing of the main and driven gears to transport the melt.The working volume consists of the tooth groove of pump body and gear and the bearing with side plate function.

2CY type gear pump

It can be used as transmission and pressure pump in oil transportation system.

In the fuel system can be used as transport, pressure, jet fuel pump.

It can be used as a hydraulic pump to provide hydraulic power in the hydraulic drive system.

It can be used for lubricating oil pump in all industrial fields.

The 2CY gear pump mainly consists of gear, shaft, pump body, pump cover, bearing sleeve, shaft end seal and other components.The gears and shafts are subjected to strict heat treatment and have high hardness and abrasion resistance.All operating parts in the pump are lubricated by the medium they transport.

The four bearing sleeves in the gear pump are installed floating in the pump body, and the end face interval is automatically adjusted with the working pressure. Therefore, the pressure of the pump is stable, the output flow fluctuation is small, and the volume efficiency is high.

(l) the disassembly and cleaning of the pump, the lifting and cooling of the pump, and the starting and stopping of the pump shall be carried out in strict accordance with the regulations to avoid undue losses.

Matters needing attention

(2) attention should be paid to keeping the population pressure of the booster pump stable so that it has a stable volumetric efficiency, which is conducive to the stable operation of the pump itself and the stability of the downstream spinning quality.

(3) the stuffing shaft seal pump with negative population pressure shall keep the packing gland pressure higher than the external atmospheric pressure.When the back pressure is reduced, the pressure of the stuffing box should be adjusted in time, otherwise the pump will inhale the air, resulting in a broken belt of the cast strip, affecting the granulation, leading to the discharge of the granulator.

(4) the temperature of the heat medium jacket should be constantly checked, and the temperature of the main body should be consistent with that of the front cover and the back cover.

(5) every increase production, to the time of the production, rotational speed, the record, inlet pressure, current value, and to compare the data before and after the careful analysis, in order to detect anomalies, handle in time.
