YCB series non - embroidered steel arc pump

YCB series non - embroidered steel arc pump depends on the working volume change and movement formed between the pump cylinder and the meshing gear to transport liquid or pressurized rotary pump.

External meshing double gear pump structure. The teeth are of double arc sinusoidal shape, and a pair of meshing gears and pump cylinders separate the suction cavity from the discharge cavity. When the gear rotates, the volume of the teeth on the side of the suction cavity increases gradually, the pressure decreases, and the liquid enters the teeth under the action of pressure difference. As the gear rotates, the fluid between the teeth is carried to the discharge chamber. At this time, the volume between teeth at the engagement of the teeth on the side of the discharge chamber is gradually reduced, and the liquid is discharged. Gear pump is suitable for conveying lubricating liquid without solid particles, non-corrosive and large viscosity range. Pump flow up to 300 m 3/ h, pressure up to 3×107 pa. It is usually used for hydraulic pumps and transportation of various oil products. Gear pump structure is simple and compact, easy to manufacture, convenient maintenance, self-priming capacity, but flow, pressure pulsation and noise. Gear pump must be equipped with safety valve, in order to prevent due to some reason such as discharge pipe blockage so that the pump outlet pressure exceeds the allowable value and damage to the pump or prime mover, safety valve opening pressure is generally 1.5 times the working pressure.

YCB series non - embroidered steel arc pump is a positive displacement pump, composed of two gears, pump body and cover two closed space, when the gear rotation, gear off the side of the space volume from small to large, forming a vacuum, the liquid suction, gear meshing side of the space volume from large to small, and the liquid into the pipeline. The suction cavity and the discharge cavity are separated by the meshing lines of two gears.

The pressure of the outlet of the gear pump depends entirely on the size of the pump source resistance.
