two Intel hydraulic motor Application of

Intel series Hydraulic motor It is a product manufactured by a professional hydraulic motor manufacturing company jointly established by a hydraulic motor factory in southern China, Italy Intemot Company, Italy Hydraulic Motor Research and Development Co., Ltd. (R&D.sR.L), and SA1 Hong Kong Branch. According to the field survey, the NHMM series hydraulic motors manufactured by this company have not only used the latest research achievements such as Italian zhuanli oil distributor, but also used the new domestic piston structure zhuanli. The product quality is guaranteed by the machining center and CNC machine tools made in Japan. Since our port adopted this type of motor in June 1998, it has the following advantages

1) It is a five piston structure with eccentric shaft and relatively low excitation frequency, so the noise is low.

2) The starting torque is large. The rated torque of 1JMD hydraulic motor of the same type is only 7350Nm, and the higher pressure is 22MPa; The NHM type can reach 9530Nm, the higher pressure can reach 32MPa, the adjustable range is large, the slow speed performance is stable, and it can operate stably at a lower speed.

3) The invented zhuanli plane compensation valve distributor has good stability and less leakage. The piston and cylinder hole are sealed by plastic piston rings, so it has high volumetric efficiency. Carry out anti blocking inspection, which has a higher working stability than that of the widely used blocking detection device. At the same time, as long as the national industry standards can be strictly implemented, the relevant national regulations on radiation protection can be met, the operating procedures can be strictly implemented, and the supervision of radioactive elements can be strengthened, the safety of the device will be fully guaranteed. However, in view of the radioactive elements used in the x-ray level meter, the following situations should be noted during use:

1) Before using the X-ray level meter, it shall be reported to the national competent authority for approval according to relevant regulations; After being approved, they can go to the local public security, health and environmental protection departments for filing, so as to carry out safety work together.

2) Although the radiation of the device to human body is not large, safety precautions should still be taken during use. In addition to the work needs, the field workers should avoid the radiation source as much as possible and try to avoid staying near the radiation source.

3) After years of use, the intensity of the radiation source will become weaker, and the instrument needs to be readjusted. The user department must not adjust it independently. It is not allowed to throw away the source chamber or bury it underground without authorization because of the weak intensity of the radiation source. It should be returned to the competent authority according to relevant regulations.

4) The crankshaft and connecting rod are supported by rollers, and the connection between the piston and connecting rod has used the mechanical energy invented by ZHUANLI. 816% higher than similar hydraulic motor of LJMD-100.

5) The direction of movement can be reversed, and the output shaft can carry radial and axial forces, and the speed ratio can be adjusted relatively large.

6) The connection methods of the output end of the hydraulic motor are diversified, especially the spline shaft connection. The assembly is convenient, and the operation is stable and reliable.

7) It has a high output power to weight ratio. Hydraulic motors of similar models are heavy in volume and small in volume.

8) NHM hydraulic motor The rough casting adopts nodular cast iron precision casting, which improves the internal and surface quality of the casting.

Application effect evaluation of 3NHM hydraulic motor

NHM type Low speed high torque hydraulic motor It has formed excellent economic returns and social values from Hong Kong, mainly as follows:

1) Because the NHM hydraulic motor operates stably and the equipment failure rate is low, the application availability of bucket wheel stacker reclaimer has increased by 516%.

2) According to calculation, since the application of Intel hydraulic motor, the coal loading rate of DQL1000f200:30 bucket wheel stacker reclaimer used in our port has increased by 712%, and the 1000 ton ship has decreased by 51.6% when stopping in the port, thanks to the large starting torque and high mechanical efficiency of NHM hydraulic motor.

3) Intel hydraulic motor has reliable cutting-edge technology and excellent manufacturing quality, which not only reduces the equipment failure rate of hydraulic motor, but also reduces the raw material consumption of the port. According to the survey, since the application of NHM type hydraulic motor to the four bucket wheel stackers and reclaimers in our port, only one hydraulic motor can save nearly 160000 yuan of maintenance materials for the port in one year.

4) It is convenient for staff to maintain equipment. Because the manufacturing quality of Intel hydraulic motor is reliable, it basically does not need routine maintenance, which greatly reduces the labor intensity of maintenance workers. In addition, our port uses the interface form of spline shaft connection, which not only makes the bucket wheel head of bucket wheel machine run stably and reliably, but also facilitates maintenance and installation. Previously, it usually took us six or seven hours to replace one hydraulic motor, and it can take us thirteen or three hours to replace one hydraulic motor. After adopting the Intel motor, it usually only took us two hours.
