Abstract

The utility model discloses a hydraulic system of a roll squeezer. The hydraulic system comprises a hydraulic station (1), a valve seat (2), an energy accumulator (3) and a hydraulic cylinder (4), wherein the hydraulic station (1) is connected with one end of the valve seat (2) through a first pressure pipe (5); the other end of the valve seat (2) is connected with the hydraulic cylinder (4) through a second pressure pipe (6); the energy accumulator (3) is mounted on the valve (2); and a high-pressure two-way filter (7) is connected onto the second pressure pipe (6) between the valve seat (2) and the hydraulic cylinder (4) in series. With the adoption of the hydraulic system of the roll squeezer, impurities are prevented from entering into the hydraulic cylinder, the condition of the valves on the valve seat and the hydraulic cylinder are not be damaged is ensured; and the hydraulic system of the roll squeezer has characteristics of reasonable in design, easy in implementation and convenient in cleaning and the like.

Description

Rolling machine hydraulic system
Technical field
The utility model belongs to the roll squeezer technical field, specifically, and the particularly hydraulic system of roll squeezer.
Background technique
The hydraulic system of roll squeezer is made up of parts such as hydraulic station, valve seat, accumulator, oil hydraulic cylinder and forcing pipes, owing to do not have the mounting filtering device on the pipeline between valve seat and the oil hydraulic cylinder, causes the generation of following problem easily:
1) because vibrations is prone to cause accumulator to damage, comprising the damage of parts such as pin, bolt and O RunddichtringO; The parts of these damages and the welding slag of pipeline residual etc. are by high pressure oil PF cylinder pressure; Finally retain in the rodless cavity of oil hydraulic cylinder, the to-and-fro motion meeting of oil hydraulic cylinder damage hydraulic cylinder body, piston and seal ring wants to come out the thing complete liquidation of the inside like this; Have only the dismounting oil hydraulic cylinder to clean, both having wasted man-hour has also increased operating cost.
2) impurity that retains in the oil hydraulic cylinder (mainly be because accumulator damaged part form) can not timing by the hydraulic oil refunds valve seat in the oil hydraulic cylinder rodless cavity, cause cartridge valve to stop up, even damage etc., thereby influence the proper functioning of hydraulic system.
The model utility content
The utility model technical problem to be solved is to provide a kind of impurity that can effectively prevent to get into the rolling machine hydraulic system that the valve member on oil hydraulic cylinder, the protection valve seat is not damaged.
The technological scheme of the utility model is following: a kind of rolling machine hydraulic system; Comprise hydraulic station (1), valve seat (2), accumulator (3) and oil hydraulic cylinder (4); Said hydraulic station (1) is connected with an end of valve seat (2) through first forcing pipe (5); The other end of valve seat (2) is connected with oil hydraulic cylinder (4) through second forcing pipe (6); Accumulator (3) is housed on said valve seat (2), and its key is: on second forcing pipe (6) between said valve seat (2) and the oil hydraulic cylinder (4), be in series with high-voltage bidirectional filter (7).
The utility model is set up the high-voltage bidirectional filter on second forcing pipe between valve seat and the oil hydraulic cylinder; This high-voltage bidirectional filter plays a part to filter out impurities; Can prevent effectively that the parts of accumulator damage and the welding slag of pipeline residual from getting into oil hydraulic cylinder; Protect expensive hydraulic equipment so on the one hand, increased the running rate of roll squeezer; On the other hand, cleaning only need be taken the high-voltage bidirectional filter during impurity apart and cleaned and get final product, not only makes things convenient for but also quick.
As preferably, two accumulators (3) are installed side by side on said valve seat (2).
Beneficial effect: the utility model can prevent that impurity from getting in the oil hydraulic cylinder, has guaranteed that the valve member on oil hydraulic cylinder and the valve seat is not damaged, and has reasonable in design, characteristics such as enforcement is easy, convenience for washing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1, the utility model is made up of parts such as hydraulic station 1, valve seat 2, accumulator 3, oil hydraulic cylinder 4, first forcing pipe 5, second forcing pipe 6 and high-voltage bidirectional filters 7, and two accumulators 3 are installed on valve seat 2 side by side.One end of said valve seat 2 is connected with hydraulic station 1 through first forcing pipe 5, and the other end of valve seat 2 is connected with oil hydraulic cylinder 4 through second forcing pipe 6, on second forcing pipe 6 between said valve seat 2 and the oil hydraulic cylinder 4, is in series with high-voltage bidirectional filter 7.Said high-voltage bidirectional filter 7 plays impurity screening, and high-voltage bidirectional filter 7 is a product on sale on the market, and its structure and working principle are not done at this and given unnecessary details.

Claims (2)

1. rolling machine hydraulic system; Comprise hydraulic station (1), valve seat (2), accumulator (3) and oil hydraulic cylinder (4); Said hydraulic station (1) is connected with an end of valve seat (2) through first forcing pipe (5); The other end of valve seat (2) is connected with oil hydraulic cylinder (4) through second forcing pipe (6); Accumulator (3) is housed on said valve seat (2), it is characterized in that: on second forcing pipe (6) between said valve seat (2) and the oil hydraulic cylinder (4), be in series with high-voltage bidirectional filter (7).
2. rolling machine hydraulic system according to claim 1 is characterized in that: two accumulators (3) are installed on said valve seat (2) side by side.
