The YCB circular arc gear pump relies on the change of the working volume formed between the pump cylinder and the meshing gear to move the liquid or to make it pressurized.

Externally meshing dual gear pump structure. A pair of intermeshing gears and pump cylinders separate the suction chamber from the discharge chamber. When the gear rotates, the volume between the teeth of the suction chamber side gears gradually increases and the pressure decreases. The liquid enters the interdental space under pressure differential. With the rotation of the gear, the liquid between the teeth is brought to the discharge chamber. At this time, the interdental volume at the meshing position of the discharge chamber side is gradually reduced, and the liquid is discharged. The gear pump is suitable for conveying solid particles. Corrosive. Lubricity liquids with a wide range of viscosities. Pumps flow up to 300 m3/h and pressures up to 3 x 107 Pa. It is commonly used as a hydraulic pump and transports all types of oil. The gear pump is simple and compact in structure. Easy to manufacture, easy to maintain, and self-priming, but the flow rate and pressure pulsation are large and noisy. The gear pump must be equipped with a safety valve to prevent damage to the pump's outlet pressure exceeding the allowable value due to some cause such as the discharge pipe plugging. Pump or prime mover I. How it works:

YCB circular arc gear pump is a type of positive displacement pump. It consists of two gears. The pump body and the front and back cover form two closed spaces. When the gear rotates, the volume of the space on the gear disengagement side increases from small to large, forming a vacuum and the liquid Inhalation, the volume of the gear meshing side of the space from large to small, and the liquid squeezed into the pipeline. The suction chamber and the discharge chamber is separated by the meshing line of the two gears.

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

2. Operation and maintenance (1) Check all piping flanges and joints before starting.

(2) Disk coupling, no friction and impact sound.

(3) The first start should be injected into the pump to transport liquid.

(4) The valve in the suction and discharge line should be fully opened before start-up.

(5) After verifying the motor rotation direction, start the motor.

Three. YCB arc gear pump common faults and maintenance methods:

(1) Failure phenomenon: The pump can not be discharged Cause of failure: a The direction of rotation is reversed: b Inhalation or discharge valve is closed: c The inlet is without material or the pressure is too low: d The viscosity is too high and the pump cannot seize the material Countermeasure: a Confirm rotation direction: b Confirm whether the valve is closed: c Check the valve and pressure gauge: d Check the viscosity of the liquid. If the flow rate is proportional to the speed at low speed, if there is flow, then the flow will not be sufficient.

(2) Failure phenomenon: Insufficient pump flow rate Cause of fault: a. Intake/discharge valve closed: b Inlet pressure low: c. Outlet line blocked: d Packing box leakage: e Low rotation speed Countermeasure: a Confirm the valve is closed: b Check the valve Open: c Confirm that the discharge is normal. d Tighten: When a lot of leaks affect the production, stop the operation. Demolition check: e Check the actual speed of the pump shaft
