Description
Technical Field
The utility model relates to a hydraulic loom technical field, in particular to hydraulic pressure monitoring devices of hydraulic loom weft insertion system.
Background
The water jet loom uses water as weft insertion medium, and the water jet produces friction traction force to weft to drive the weft to enter a shed and interweave with warp into fabric. The weft insertion system of the water-jet loom comprises a water pump, an inlet one-way valve arranged on the water inlet end of the water pump, an outlet one-way valve arranged on the water outlet end of the water pump, a water inlet pipe connected with the inlet one-way valve, a water outlet pipe connected with the outlet one-way valve and a nozzle connected with the water outlet pipe.
The working principle is as follows: when the pump cam of the water pump is turned from a small radius to a large radius, the connecting shaft lever is driven by the pump cam lever to move leftwards, so that a pump spring of the water pump is compressed, negative pressure is formed in the water pump, the inlet check valve is opened, the outlet check valve is closed, and water is sucked into the water pump. When the cam of the water pump is suddenly reduced from the maximum radius to the minimum radius, the plunger of the water pump is rapidly moved rightwards under the action of the pump spring, and the pressure is directly acted on the water column sucked into the water pump, at the moment, the inlet one-way valve is closed, the outlet one-way valve is opened, the water is pressed out from the water pump and then is sprayed out from the nozzle through the water outlet pipe.
In the process that the jet water of the nozzle drives the weft yarn to enter a shed, if the water pressure of the jet water is too low, the friction traction force borne by the weft yarn is too low, so that the weft yarn cannot be interwoven with the warp yarn to form a fabric due to the reduction of the moving stroke of the weft yarn; if the water pressure of the sprayed water is too high, the friction traction force on the weft yarn is too high, and the weft yarn has certain elasticity, so that the quality of the fabric is influenced due to excessive deformation of the weft yarn; therefore, flexible weft insertion is led out, and then the water pressure of the sprayed water is smaller and better on the premise that the weft yarns and the warp yarns can form a fabric.
Therefore, in the process of driving the weft yarns to move by the sprayed water, the water pressure of the sprayed water is reduced on the premise that the weft yarns can be interwoven with the warp yarns into a fabric, and the weft yarns of different specifications are driven by the water pressure of different sprayed water; in practical production, in order to facilitate processing, the water pressure of the sprayed water is usually selected to be properly increased so as to ensure that the weft yarns of various specifications are driven to be interwoven with the warp yarns into a fabric, and the quality of the weft yarns is influenced at the moment.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: a water pressure monitoring device of a weft insertion system of a water jet loom comprises a water pump 1, an inlet one-way valve 2 arranged on the water inlet end of the water pump 1, an outlet one-way valve 3 arranged on the water outlet end of the water pump 1, a water inlet pipe 4 connected on the water inlet end of the water pump 1, a water outlet pipe 5 connected on the water outlet end of the water pump 1, and a nozzle 6 connected on the water outlet pipe 5, wherein the water pressure monitoring device is shown in figure 1. A first pressure sensor 7 for detecting the water pressure entering the water inlet pipe 4 is arranged at the water outlet end of the water pump 1, a second pressure sensor 8 for detecting the pressure in the pump body is arranged on the pump body of the water pump 1, and the first pressure sensor 7 and the second pressure sensor 8 are electrically connected with a display 9 through leads; the display 9 is used for receiving the electric signals from the first pressure sensor 7 and the second pressure sensor 8 and displaying the electric signals into pressure values.
The implementation effect is as follows: aiming at a certain type of weft yarn, the water pressure of the sprayed water is firstly increased for debugging, so that the weft yarn can be interwoven with the warp yarn into a fabric under the water pressure of the sprayed water, and the water pressure of the sprayed water is displayed on a display 9 through a first pressure sensing; gradually reducing the water pressure of the sprayed water, when the weft yarns are just interwoven with the warp yarns into a fabric under the driving of the water pressure of the sprayed water, the displayed water pressure on the display 9 is the lowest water pressure required by the weft yarns of the type, and recording the type of the weft yarns and the water pressure numerical value on the display 9; and replacing the weft yarns of different models, and repeating the steps to record the water pressure value of the lowest water pressure required by the weft yarns of various models. Finally, the fabric quality is improved, and water resources are saved.
When the pressure in the pump body of the water pump 1 is close to the pressure at the water outlet pipe 5, the water flows smoothly in the weft insertion system, when the influence caused by the gradual reduction of the pressure in the pump body due to the leakage of the water at the plunger of the water pump 1 is reduced, the water pressure value displayed on the display 9 by the first pressure sensor 7 needs to be smaller than the water pressure value displayed on the display 9 by the second pressure sensor 8 by replacing the inlet check valve 2 with different specifications, and the water pressure value displayed on the display 9 by the first pressure sensor 7 is close to the water pressure value displayed on the display 9 by the second pressure sensor 8, so that the specification of the inlet check valve 2 required in the weft machining of the type is determined.
Meanwhile, when a certain type of weft yarn is processed, one or more of the nozzle 6, the outlet check valve 3 and the water pump 1 of different specifications are replaced, so that the water pressure value displayed on the display 9 by the first pressure sensor 7 reaches the minimum water pressure required by the weft yarn, and the specifications of the nozzle 6, the outlet check valve 3 and the water pump 1 required by the weft yarn processing of the type are determined.
