Embodiment 1

[0043] Embodiment 1: see Figure 1-Figure 5 , a method suitable for the stable operation of a bladder accumulator, the method comprising the following steps:

[0044] (1) Determine the minimum and maximum working pressure of the system and the capacity of the accumulator according to the design requirements of the system;

[0045] (2) According to the actual site and verification comparison, mainly determine the capacity of the accumulator (whether it needs to be increased);

[0046] (3) Determine the basic inflation pressure of the bladder accumulator according to the system flow rate and the detected actual working pressure;

[0047] (4) Determine the final inflation pressure of the bladder accumulator according to the different usage conditions of the bladder accumulator;

[0048] (5) Determine the nitrogen pressure that needs to be supplemented by detecting the actual inflation pressure of the accumulator;

[0049] (6) Charge the accumulator with nitrogen;

[0050] (7)...

Embodiment 2

[0073] see figure 2 A device suitable for the stable operation of bladder accumulators. To check the charging pressure of the accumulator, connect a pressure gauge 2 to the circuit shown in the figure, and slowly open the shut-off valve 3 to fill the accumulator 1. While the pressure oil is gradually leaking to the oil tank 4, pay attention to observe the pointer of the pressure gauge 2. The pointer of the pressure gauge 2 slowly turns to the low-pressure end first, and then quickly turns to zero after reaching a certain pressure value. At this time, the shut-off valve 3 is quickly closed. The pressure reading when there is a sudden change when the pointer rotates is exactly the inflation pressure of the accumulator 1.

Abstract

The present invention relates to a method suitable for the stable operation of a bladder accumulator. The method includes the following steps: (1) Determine the minimum and maximum working pressure of the system and the capacity of the accumulator according to the design requirements of the system; (2) Mainly determine the capacity of the accumulator (whether it needs to be increased) according to the actual situation on site and verify and compare; (3) Determine the basic inflation pressure of the bladder accumulator according to the system flow rate and the actual working pressure; (4) According to Determine the final inflation pressure of the bladder accumulator according to the different usage conditions of the bladder accumulator; (5) Determine the nitrogen pressure that needs to be supplemented by detecting the actual inflation pressure of the accumulator; (6) Fill the accumulator with nitrogen (7) The system runs stably, waiting for the next detection.

Description

technical field [0001] The invention relates to an accumulator, in particular to a method suitable for the stable operation of a bladder type accumulator, and belongs to the technical field of hydraulic structural components. Background technique [0002] The accumulator is a device that stores the potential energy of the working medium. In the gap load of high pressure and large flow or the continuous load system of different sizes, sometimes the flow required by each stage in a working cycle is also very different, and the peak flow load The time is often relatively short. For this situation, although there are many solutions, an important way is to use accumulators as auxiliary energy, especially in the hydraulic system of constant pressure variable pumps. Due to the bladder type accumulator Energy devices have the advantages of small size, light weight, small inertia, sensitive response and strong shock absorbing ability, etc., and are widely used. When the flow require...
