Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, the utility model discloses an embodiment of a pressure seal of plunger 111 for high-pressure pump examines equipment, including operation platform 1, operation platform is last to fix and is provided with fixed baseplate 2, the last plunger mounting hole 3 that is provided with of fixed baseplate, the fixed pump head 4 that is provided with on the surface along plunger mounting hole axial one end, be provided with pressure chamber 5 in the pump head, the pressure chamber is link up with the play water end 6 and the end 7 of intaking of pump head, be provided with check valve 8 and outlet valve 112 between play water end and the pressure chamber, be used for installing seal assembly 9 between pressure chamber and the plunger mounting hole, still be provided with pressure plate 10 along plunger mounting hole axial other end, be provided with two at least guide posts 11 on the pressure plate, the guide post passes guide holder 12 and is connected with stopper 13, the guide holder is fixed on fixed baseplate, the pressure plate is connected with; the end of intaking of pump head passes through force pump 15 and is connected with the water tank, and the play water end of pump head leads to pipe to be connected with the water tank.

The fixed baseplate can be formed by the cutting of a crankcase, the installation end part of the plunger is exposed, direct observation is facilitated, the plunger is in a translation type reciprocating movement mode, no requirement is imposed on the speed, oil does not need to be injected, the sealing assembly can be normally installed, and the matching degree of the sealing assembly and the plunger is effectively detected.

When in use, the guide post is clamped by the limiting block firstly, the limiting block is moved to the end part of the guide post, then the pressure plate is pulled out, so that the pressure plate and the fixed base have a sufficient length therebetween, the plunger is inserted from the space, then inserted into the plunger mounting hole and one end of the plunger mounting hole extends out of the plunger mounting hole, then the pressure plate is moved to ensure that the pressure plate is pressed against the end part of the plunger, then the oil seal of the seal assembly is mounted on the plunger, the water seal ring of the seal assembly is mounted on the pump head, and then the pump head is fixed on the fixed base, wherein, the plunger is required to be aligned with the pump head, the plunger extends into the pressure cavity, the distance between the pressure plate and the end part of the plunger is adjusted according to the stroke of the plunger, after the position is adjusted, the limit block is moved to abut against the guide seat and then fixed, thus, stroke fixation can be realized, and the plunger and the sealing assembly are always in a normal use position range in the detection process as shown in the figure 2. After the installation is finished, the water in the water tank is injected into the pump head by the pressure pump, the pressure intensity in the pump head is controlled by the injection pressure of the pressure pump, the water outlet valve is closed to be small, so that the water in the pressure cavity can not be normally discharged, the pressure is controlled by the water injection pressure and the water yield of the pressure pump, the pump head directly returns into the water tank after water is discharged, in the process, the pressure plate is pushed by the power source, the pressure plate moves towards the pump head against the plunger, then the power source is reset, because the pressure chamber has higher water pressure and the thrust of the plunger disappears, the water pressure presses the plunger to withdraw from the pressure chamber, therefore, the plunger can be reset against the pressure plate, the power source repeatedly acts to simulate the movement of the plunger, and the movement at the position cannot reach the displacement speed of the plunger in the high-pressure pump, but the quality of the matched seal of the plunger and the sealing assembly can be detected by moving, and whether water exists on the exposed surface of the plunger or not can be observed.

When needs pressurize experiment, can close the outlet valve, the water of pressure chamber can't be discharged like this, improves pressure through force pump water injection pressure, closes the force pump afterwards, and the pressure of guaranteeing the pressure intracavity waits the pressurize time quietly, and it can to observe whether there is rivers to flow or ooze.

The pump head can be also provided with a pressure gauge 19, and the pressure in the pressure cavity can be observed through the pressure gauge, so that the adjustment is convenient.

Specifically, the power source is an oil cylinder or an electric screw rod sliding table, the oil cylinder has strong thrust, and the electric screw rod sliding table can control the movement amount of reciprocating movement with high precision. In order to facilitate the operation, the limiting block is sleeved on the guide post and can be adjusted through sliding, a set screw 16 for fixing the limiting sleeve and the guide post is arranged on the periphery of the limiting block, the set screw supports the guide post from the radial direction, and therefore the limiting block is fixed, and the condition of convenient operation is met.

And the bottom of the fixed base is provided with a locking extension part 17, so that the installation firmness of the fixed base is improved. The fixed base is provided with a plurality of limiting rubber pads 18 on the surface of one side of the pressure plate, so that the plunger is prevented from being excessively pressed and damaged.
