Reciprocating piston rod seal between the pressure of seal series

Asked the pressure balance seal ring. 3.2.3 sealing pressure on the oil temperature of the open test is through the heat exchanger to control the oil temperature. Oil temperature curve. From the graph above,[link widoczny dla zalogowanych], the seal oil pressure not only affects the rate of temperature rise. But also affected the oil will eventually reach the equilibrium temperature curve of the figure shows, high pressure sealing system of the friction, heat also large. Therefore, the temperature rose quickly. Low pressure sealing system friction small. Fever also small, so the temperature rises slowly. At the same time,[link widoczny dla zalogowanych], can know. High pressure to reach balance in the final high temperature, low pressure will eventually reach the equilibrium temperature is low. And the equilibrium temperature affected by environmental temperature. In the hot summer. Relatively high temperature sealing system. Cooling measures must be taken at this time. To reduce the temperature to ensure a long life seals. Finally,[link widoczny dla zalogowanych], note should be sealed with the seal series is the series increase. Will bring great friction. Xia fever. High temperature seal life of a range of issues. At the same time, the seal structure and a sealing system seems complex and huge. Thus,[link widoczny dla zalogowanych], the most commonly used is the tandem seal series 2-3 level. And the temperature is generated by the friction. Figure 8 shows. \Good composition and size optimization, needs further study: 524 Conclusion (1) series pressure seal between the cover may be formed in two ways: one is when P ? '�� time. the outcome of Pb = Ps-PsPs-o. the outcome of P. <P5 ~. Ps - Pso and P '= Ps-11 (1 one by one () ��2) According to the series sealed sealed at all levels of the critical pressure, when the sealing pressure is known. you can use the form recursive method (see Table 1) and the formula m = P. +1. obtained the required seal series series ��3) The experimental results show that; balance the pressure by the press seal closure pressure. which is independent of temperature; the establishment of speed with temperature, sealing pressure is changed. and high temperature. speed; temperature is low, slow; pressure, high speed; pressure is low and slow.
