Tractor pump is an important part of the tractor hydraulic system, usually refers to the piston oil pump, mainly composed of pump body, plunger, plunger spring, eccentric wheel, steel ball and check valve. This single-piston pump is easy to process and reliable to use, and because the control and safety valves are also mounted on the pump body, they are compact and have few oil leaks.
In the Tractor Pump, the plunger spring keeps the plunger in constant contact with the 108 ball bearing, and there is an annular groove in the north of the plunger that communicates with the inlet and return ports. There is a radial through hole drilled in the groove, and the through hole communicates with the axial hole in the center of the plunger to form the oil inlet channel of the oil pump. The steel ball is installed below the shaft hole (it plays the role of a check valve when pressing oil), and a limit pin is installed above the steel ball to limit the height of the steel ball in the plunger suction stroke. There is a check valve under the plunger, which consists of a check valve body, a check spring, and a check screw cover. In addition, the Tractor Pump includes a safety valve and a control valve. The control valve is a rotary valve directional control valve, which is used to control the flow direction of oil, and has three positions: lifting, neutral and descending, which can make the farm tools lift, maintain a certain height and reduce three working conditions.
When using a tractor pump, you need to pay attention to checking and maintaining the hydraulic system to ensure that the pump is working properly. At the same time, it is also necessary to pay attention to safety during operation, comply with operating procedures, and avoid accidents.
Tractor Pump Daily Inspection:
1. Check the appearance of the tractor pump to make sure there are no oil leaks, damaged or loose parts.
2. Check the oil level to ensure that the oil level is within the recommended range. If the oil level is too low, a suitable hydraulic oil should be added in time.
3. Check the connections and fixings of the pump to ensure that they are fastened and reliable.
Tractor Pump Cleaning:
1. Clean the Tractor Pump and its surroundings regularly to avoid dust and debris from entering the pump.
2. Keep the surface of the pump body dry and avoid contact with moisture and corrosive substances.
Check the seals:
1. Check all seals of the pump, such as O-rings, oil seals, etc., to make sure they are not worn or aged.
2. If the seal is found to be damaged, it should be replaced in time.
Inspect tubing and fittings:
1. Check all the pipes and fittings connected to the pump to make sure they are not leaking or loose.
2. If it is found that the pipeline or joint is leaking, it should be repaired or replaced in time.
Check performance regularly:
1. During the working process of the tractor, regularly check the working performance of the pump, such as flow, pressure, etc.
2. If the performance is found to be degraded or unstable, it should be stopped in time for inspection, find out the cause and repair.
Tractor Pump Maintenance:
1. According to the manufacturer's recommendations, carry out regular maintenance, such as changing the engine oil, cleaning the filter, etc.
2. Appropriate tools and materials should be used during maintenance to ensure correct operation.
The above recommendations are for reference only, and specific maintenance and inspection steps may vary depending on the tractor pump model and manufacturer. Therefore, when performing maintenance and inspections, be sure to refer to the owner's manual of the tractor pump you are using or consult the manufacturer's technical support personnel.
