Gear pumps (gear pump) rely on the work of the pump cylinder and the volume change and move the engagement between the gear formed to transport liquid or pressurized so that the rotary pump. Intermeshing twin gear pump outside the structure. A pair of intermeshing gears of the pump cylinder and the suction chamber and a discharge chamber are separated. When the gear rotates, the gear teeth are disengaged from each side of the suction chamber at a gradually increasing volume of the teeth, the pressure drops, the liquid in the pressure differential into the teeth. With the rotation of the gear, the teeth of one are brought to the liquid discharge chamber. In this case the volume of the discharge chamber side teeth meshing is gradually reduced, while the liquid is discharged. Gear pump for conveying solid particles, non-corrosive, lubricating viscosity range larger liquid. Pump flow can be up to 300 m 3 / h, pressure up to 3 × 107 Pa. It is usually used for transporting various types of hydraulic pumps and oil. Gear pump structure is simple and compact, easy to manufacture, easy maintenance, self-priming capability, but the flow, pressure pulsation large and noisy. Gear pumps must be equipped with safety valve to prevent some reason, such as clogging the pump discharge pipe outlet pressure exceeds the allowable value of damage to the pump or prime mover (a), it works: gear pump is a positive displacement pump consists of two a gear pump consists of two front and rear cap closed space when the gear rotates, the gear disengagement side volume from larger space, forming a vacuum, the liquid inhalation, the volume of the side gears space from large to small, and squeeze the liquid pipeline to go. Suction chamber and the discharge chamber is by wire meshing gears to separate the two. Gear pump discharge pressure at the outlet of the pump depends entirely on the size of the source resistance. (Two), operation and maintenance of a starter: Check all pipe flange (1) Before starting, sealing joints. (2) dynamic disk couplings, friction and collision sound. (3) The first time you start the transmission fluid should be injected into the pump. (4) Before starting the suction and discharge piping should be fully open the valve, non-closing valve starts. (5) After verifying the motor rotation direction, start the motor. 2 Parking: (1) Close the motor. (2) Close the inlet and outlet valves of the pump. [Company Name] Tengzhou Machine Co., Ltd.
