(1) The operation of the new machine should pay attention to the operation within three months During the operation of the new machine, should grasp the operational status checks, such as maintenance of the machine, the screws are loose, the oil temperature is not abnormal increase, whether the hydraulic oil Quickly deteriorated, check the conditions of use compliance and so on. (2) do not immediately after the start of the hydraulic pump to increase the load After the start of the hydraulic pump to be carried out for some time no-load idle (about 10 minutes to 30 minutes), especially when the temperature is very low, but also by the vehicle process, the hydraulic circuit cycle Normally added to the load, and confirm the operation status. (3) observe the changes in oil temperature Attention to check the maximum and minimum oil temperature changes, and find out the relationship between oil temperature and ambient temperature, so you can know the cooler capacity, storage tank capacity and the surrounding conditions, the conditions of use of each other, the cooling System troubleshooting also has its own way. (4) Pay attention to noise of hydraulic pump The new hydraulic pump has low initial wear and tear and is easily affected by air bubbles and dust. Poor lubrication at high temperatures or over-service conditions can cause adverse consequences and cause abnormal effects on the hydraulic pump. (5) Note Check the display value of the instrument class Observe the pressure gauge display value of the hydraulic circuit, pressure switch lights and other vibration conditions and stability at any time, in order to early detection of the hydraulic circuit function is normal. (6) Pay attention to observe the mechanical operation (for modified pump) Improper design of hydraulic circuit or component manufacturing is not easy to find in the initial use stage, so pay special attention to the operating conditions under various conditions of use. (7) Pay attention to the adjustment in each valve Fully understand the use of pressure control valve, flow control valve and directional control valve. Pay special attention to the adjustment range and limit, otherwise the adjustment error not only damages the machinery, but also poses a threat to safety. (8) check the status of the filter on the loop filter should be regularly removed and cleaned, and check the status of the filter and the net adsorption of dirt, analysis of quality, quantity and size, so you can observe the degree of pollution in the circuit, and even according to This concludes that the source of the pollution. (9) regular inspection of hydraulic oil changes every one or two months to check the analysis of hydraulic oil deterioration, discoloration and pollution changes in order to ensure the normal hydraulic transmission medium. (10) pay attention to the leakage part of the piping Hydraulic equipment piping good or bad, after a period of operation can be seen, the prosecution is oil spills, plumbing is loose. (11) Attention should be paid to the anomalous sound, vibration or abnormal signal of monitoring system, etc., at any time. When the abnormal phenomenon is found, the circuit diagram is immediately found and the diagram is taken. Careful observation is made as to whether the abnormal phenomenon is a temporary error . Assessment need not need parking treatment. All pressure, load, temperature, time, start, stop when it includes the possible causes of abnormal phenomena. Usually that should be one by one analysis and discussion.
The chips feature high dispersion, high transparency, high gloss, and bright color, without smell or dust, and meanwhile maintain stable performance, safety, and environmental protection, which generate great benefits in terms of storage and transportation. With its excellent compatibility and dispersibility, Keytec Pre-Dispersed Pigment Chips allow customers to prepare their ideal colorants in a short time. The relatively high pigment content generally ranges from 30% to 80% (which depends on system types), while the resin content can reach 20% to 70%.
