YHCB Circular Arc Gear Pump

YHCB arc gear pump is mainly suitable for conveying various liquids with a temperature not exceeding 180 ℃, without solid particles or corrosive properties; Such as gasoline, kerosene, diesel mechanical lubricants, liquefied petroleum gas, diamine acetate, triamine acetate, and hexamine acetate.

YHCB arc gear pump is an energy-saving gear pump with advantages such as high flow rate, high pressure, small volume, low noise, good self suction performance, and convenient installation and maintenance. It is also an ideal pump type for the oil tank car modification industry and the petroleum sector,

YHCB arc gear pump refers to JB/T6434-92 standard.

Note: If used as a beverage pump or chemical raw material pump, materials can be used for production according to user requirements and actual media conditions.

Product Installation and Maintenance Rules for YHCB Circular Arc Gear Pump

1、 The pump can be installed in refueling vehicles and oil depot pump rooms, and the installation oil circuit design on the vehicle should comply with the specified functions in Article 4.18.1 of GB9414-88.

2、 When installing and using on a fuel truck, attention should be paid to:

(1) The pump is driven by the output shaft of the power take-off of the car gearbox. The pump should be installed as far forward as possible, and the inclination angle between the pump shaft and the transmission shaft should not exceed 7 degrees.

(2) The pump should be lifted onto an angle steel welded hanger, and the height of the pump can be determined based on the output shaft axis of the power take-off. The left and right positions of the pump should be as close as possible to the car longitudinal beam (to avoid interference between the pump and the car drive shaft), and fixed on the car longitudinal beam with bolts.

(3) The suction pipe mouth should not be less than 70mm, and the vertical suction should not exceed 5m

(4) During operation, the pressure gauge should not exceed 0.5Mpa. The vacuum gauge should not exceed -0.08Mpa.

3、 It is prohibited to operate the pump when the pump is not filled with liquid. Otherwise, it will burn out the seal.

4、 Before operating the YHCB arc gear pump, the motor direction, flange, and joint sealing should be verified. Carefully check whether each valve is opened and closed correctly. It is prohibited to start the oil pump without opening the valve in the pump outlet pipeline. To avoid accidents.

5、 Regularly, usually once every two weeks, clean the filter. To avoid blockages that affect flow, regularly check and adjust the oil pressure of the protective valve. The diameter of the inlet pipe shall not be lower than that of the outlet pipeline.

6、 The pump should run from low to high, slowly accelerating and maintaining the corresponding speed. It is not allowed to operate at excessive speed, nor can it fluctuate high or low.

7、 During the operation of the pump, attention should be paid to observing the readings on the pressure gauge and vacuum gauge. If the pressure gauge reading is too large, it indicates that the head is too high or the pump outlet pipeline is blocked and overloaded. If the vacuum gauge reading is too large, it indicates that the suction head is too large or the suction pipe is blocked, which is due to pump cavitation

8、 If the pump is stopped for a long time, it should be treated with rust prevention and properly stored.

9、 Add calcium based grease to the bearings every six months.

10、 The pipeline should have a pipe rack, and the pump is not allowed to bear the load of the pipeline. The installation height of the pump should not exceed the allowable vacuum suction height during pump operation.

11、 Turn off the motor within the parking time limit, and then close the outlet valve of the pump.
