Description

Technical Field

[0001] The utility model relates to the technical field of grouting equipment, in particular to a grouting equipment with an adjustable pressure lubrication oil circuit. Background Art

[0002] At present, the working principle of the plunger pump is mostly to achieve the movement of slurry by causing an imbalance in internal pressure through the reciprocating motion of the plunger. As a plunger pump that achieves internal slurry movement through pressure, it itself has a better requirement for sealing.

[0003] During the reciprocating motion of the plunger, it is necessary to add lubricating oil or set up an oil circuit to ensure the reciprocating motion effect of the plunger. However, when the slurry pressure is too large and the sealing plug is prone to wear after long-term use, the slurry will enter the lubricating oil through the gap, reducing the purity of the lubricating oil, affecting the reciprocating motion of the plunger, resulting in a decrease in the transmission efficiency of the slurry and affecting the construction. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the above-mentioned technology and provide a grouting device with an adjustable pressure lubricating oil circuit.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a grouting equipment with an adjustable pressure lubricating oil circuit, including a cylinder body, a connecting sleeve, a grouting channel, and a plunger; the connecting sleeve is inserted into the cylinder body, and a protective sealing ring is provided between the connecting sleeve and the cylinder body; a groove body is provided on the left side of the connecting sleeve, a rear sealing ring is provided inside the groove body, and a front sealing ring is provided on the right side of the cylinder body, and an oil circuit is formed between the front sealing ring and the connecting sleeve; the grouting channel is located on the right side of the cylinder body and communicates with the inside of the cylinder body; a through hole is provided on the connecting sleeve for use with the plunger; the end of the plunger passes through the rear sealing ring, the through hole, The oil circuit and the front sealing ring are located in the grouting channel; an oil inlet channel is provided on the upper side of the cylinder body, and a discharge channel is provided on the lower side of the cylinder body, and the oil inlet channel and the discharge channel are both connected with the oil circuit; a compression spring and a ball are provided inside the oil inlet channel, one end of the compression spring is fixedly connected to the oil inlet channel, and the other end of the compression spring is fixedly connected to the ball; an oil pot is provided on the top of the oil inlet channel, and the ball is against the oil outlet of the oil pot; a pull rod is provided inside the discharge channel, and an auxiliary spring is provided on the outside of the pull rod, the auxiliary spring is fixedly connected to the discharge channel, and the bottom end of the pull rod is located outside the discharge channel; a discharge port is provided on the discharge channel.

[0006] Preferably, the pull rod is T-shaped.

[0007] Preferably, the number of the discharge ports is 2 to 4.

[0008] The beneficial effects of the utility model are: 1. The pressure of the grouting channel is changed by the reciprocating motion of the plunger, thereby realizing the transportation of slurry; when the slurry pressure is too high and the front sealing ring is worn out after long-term use, the slurry will penetrate into the oil circuit through the gap. The slurry is generally water-soluble and will sink to the bottom of the oil circuit, and will press the pull rod down to be discharged through the discharge channel. At this time, the internal pressure of the oil circuit becomes smaller, the ball pressure of the oil inlet channel increases, and the compression spring is squeezed. The oil pot is connected with the oil inlet channel, and the lubricating oil in the oil pot will enter the oil circuit to supplement the missing lubricating oil, so that the lubricating oil in the oil circuit is always kept full and the oil circuit pressure requirement is met, thereby ensuring the stable and efficient operation of the plunger and increasing the grouting effect.

[0009] 2. When the oil circuit needs to be cleaned, manually pull the pull rod outward to connect the oil circuit and the discharge channel for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The pull rod 16 is T-shaped and will resist the inlet of the discharge channel 12. When the pressure in the oil circuit exceeds the elastic force of the auxiliary spring 17, the pull rod 16 will move downward to connect the oil circuit 9 with the discharge channel 12, thereby discharging excess slurry or lubricating oil.

[0016] The number of the discharge ports 18 is 2 to 4.

[0017] When the utility model is used, the pressure of the grouting channel 3 is changed by the reciprocating motion of the plunger 4, thereby realizing the transportation of the slurry; when the slurry pressure is too high and the front sealing ring 8 is worn out after long-term use, the slurry will penetrate into the oil circuit 9 through the gap.

After the compression spring 13 is squeezed, the oil pot 15 is connected with the oil inlet channel 11. The lubricating oil in the oil pot 15 will enter the oil circuit 9 to supplement the missing lubricating oil, so that the lubricating oil in the oil circuit 9 is always kept full and the pressure requirement of the oil circuit 9 is met, thereby ensuring the stable and efficient operation of the plunger 4 and increasing the grouting effect.

[0018] When the oil circuit 9 needs to be cleaned, the pull rod 16 is manually pulled outward to connect the oil circuit 9 with the discharge channel 12 for cleaning.
