Woodworking cold press is a complete set of woodworking machinery equipped by general hot press manufacturers and furniture factories. It is mainly used to leveling and setting furniture. It can also make the bonding between boards more robust, less pressure and no backlash. Yesterday and we fragmented an article about how to make smooth operation of carpenter cold press. Today, Xiaobian shares with us the article that assumes that the smooth operation of carpenter cold press will bring harm to the cold press if it is not timely.
The defect of smooth part of carpenter cold press is not the problem of smooth system itself, but it will also lead to the defect of system. For example, improper selection of piston ring structure in cylinder and improper processing equipment can constitute many oil-running phenomena; abnormal leakage of shaft seal will also make the oil surface in crankcase decrease significantly, leading to oil suction; small vacancies of connecting rod, large and small head bearing bush and front and rear main bearing equipment, too dirty smooth oil and smooth oil deterioration will increase the moving parts. Conflict and wear; when cylinder wear is severe, it will appear high and low pressure gas channeling, which will lead to crankcase heating, oil temperature rising, and smooth oil viscosity decreasing, which will constitute a vicious cycle of smooth conditions and smooth system defects.
The first sign of normal operation of smooth system of carpenter cold press is:
1. Oil pressure gauge indicates stability. Indicative pressure is 0.05-0.3 MPa higher than suction pressure for piston-type cold press and 0.2-0.3 MPa higher than condensation pressure for screw-type cold press.
2. The oil temperature in the crankcase should be kept between 10 and 65 degrees C, and the suitable operating temperature should be 35 to 55 degrees C.
3. The oil level in the crankcase should be high enough and stable for a long time.
4。 The filter element of the oil filter should not be blocked, and the fine oil filter with differential pressure should have blocked transmission instructions。
The common defects of smooth system are pressure-free oil pump, pressure regulation failure and severe shaking of pressure gauge pointer。 The primary reasons are:
1。 It is difficult for oil pump to absorb oil because of the low oil temperature in crankcase, the large clearance of frozen smooth oil, the dense filter screen at pump inlet, the blockage of filter element and the low oil surface。
2. The oil pump works for a long time, the wear of the pump is severe, the internal leakage is too large, and the volume effect is significantly reduced.
3. The pressure regulating valve core is stuck in the open position or the tension spring of the pressure regulating valve is invalid.
4. Serious leakage of the system.
Therefore, the defect analysis of smooth system should be comprehensive, that is to say, besides the problems of smooth system itself, the operation condition of cold press should be checked, analyzed and judged.
When the woodworking cold press is working, there will be more loss of each part. As for some carpenter cold presses used in daily life, they need smoothness, but they are not often used more smoothly. It is assumed that if the carpenter cold presses are not smoothed, the cold presses will be damaged. When smooth operation is done well, the service life of carpenter cold press can be extended to a relative extent.
