5 It specifies the model, basic parameters and overall dimensions, technical requirements, trial operation, inspection rules, marking, packaging, transportation and storage of single-line lubricatlon pumps 31.5MPa. This standard is suitable for a company that consumes 31.5MPa of grease and sodium. The standard is generally used for lubricating oils with a pressure of 100%. The standard is referred to as single lubricant (hereinafter referred to as single lubricant). 2 Reference standards The following standards contain clauses that are also referenced in relevant standards and become the text of this standard. When this standard is published, the versions shown are valid. All standards are subject to revision. All parties using the changed standards should discuss the use of the following standards for the repairability of the new version.

means
single load speed is under 1.15 of the nominal pressure, and there is no damage to the steel plate. 4.2 general
single load system is under 1.15 of the nominal area, and there is no full phenomenon at the external joints.
4.3 oil supply±
JB/T881.2:198
single line pressure is the nominal pressure when the The oil inlet should be adjustable within the specified range: its maximum oil supply should not be less than the specified maximum oil supply, and the oil supply should not be less than the specified maximum oil supply. 4. 1. When the back pressure of the single-line system tank is greater than the nominal pressure, the oil level alarm in the single-line system barrel should be able to send out an alarm when the oil is high and the minimum oil supply is low. 4. 6 The noise value of the single-line head should not be greater than 950m when the single-line is running down. 4. 8 Surface coating The surface coating of the single-line system should comply with the relevant standards. 4.9 Life span The service life of the system should not be less than 100% of the specified service life. When the maximum oil supply under nominal pressure is less than 7% of the specified maximum oil supply or the transmission parts are damaged and cannot be adjusted, it can be regarded as the service life of the single-line pump. 5. Test method
5.1 Test performance
single-line pump test medium is lubricating oil with a speed of 41.450.6mm/s, and the service life test quality is grease with a speed of 265~295 (5.1km: the test is reversed at room temperature and the steady-state positive force difference is 1% of the test result. The pressure gauge is 0~4CMHa, and the accuracy is 2.5.2 Test system
single-line pump test system principle is shown in basic 2.1-flow, 2.5.3.2.2.2.3.2.4.2.4.2.5.4.2 ... =MPa, adjust the oil volume to the maximum, measure the oil volume at the oil supply port! mn bell, the average should be equal to the provisions of 4.3. Adjust the volume of the card to thank the book, the volume can promote the change. 5.6 Pressure regulation and overpressure maintenance test
The pressure regulation and single-line recording time can be reduced to MP. Then wait for the pressure regulation on the single-line system to be synchronized with the low pressure sequence, and the single-line will be adjusted to 31.5MP. When the outlet pressure is less than 33MPA, the overpressure protection performance of the line should meet the requirements of 4.1: 5. In the pressure control test
, the lower limit gate and the alarm are connected, and the oil in the flow is connected. When the oil level in the monitoring outlet is lower than the low oil level, a low level alarm should be issued; when the oil level in the oil barrel is higher than the low oil level, the low-pressure high-pressure injection should be stopped! When the oil level in the oil barrel is higher than the high oil level, a high-level alarm should be issued: s. Talk about sound test
Each single line is at a certain height, when it is moving downward at the nominal stop, but there is one point in each of the four directions of the single line, and the average noise level is in accordance with the provisions of 4.
5.9 Cleaning method inspection
The single line is cleaned, and all the standard parts of the mold are flushed with exhausted petroleum ether (except the oil drum part). The flushed oil is dried in an oven at a temperature of 120°C, and the weighed medium-sized fixed plate is filtered through a paper filter, and then the filter is placed in a temperature-controlled place. 120% of the flag dried in the oven, taken out and filtered again, the difference between the weight of the filter and the power of the test is the impurity black weight. Its value should meet the requirements of 4.? 5.10 Surface screening inspection
Daily visual inspection of the pump surface coating, its quality should meet the requirements of 4.8, 5.1 Sea life test
Adjust the single line speed oil 1K force to 31.MPa. Feed the maximum amount. After running for 201, measure the supply pool according to the provisions of 5.5. The consumption should meet the requirements of 4.9.
6 Inspection rules
6.1 Factory inspection
The bus multi-mountain inspection is carried out according to 5.3.5.1, 5.5 and 5.10. 6.2 Type inspection
6.2.! Type inspection should be conducted when any of the following conditions occur: 9) First modification test, timing:
1) When the structure, material or process changes significantly, which may affect the performance of the product: L:> After 5 years of normal production.
6.2. Type inspection products should be taken from the finished products that have been inspected, and the number should not exceed two. 6.2.3 Type inspection report shall be carried out according to the provisions of Chapter 5. 6.3 If the type control test fails on the same day, double inspection shall be carried out. If the item fails on the same day, it shall be judged as unqualified product 7 Marking, packaging, transportation inspection and storage
