Abstract
Description
Technical Field
[0001] The working cylinder of the pump body of the present utility model relates to the technical field, and particularly relates to an isolation cavity structure for a double-feed pump body working cylinder. Background Art
[0002] As Figure 1 shown, the material in the existing double-feed pump body working cylinder is in direct contact with the end face of the power cylinder. After the sealing ring in the guide sleeve reaches its service life during long-term operation of the equipment, it will be damaged. At this time, the hydraulic oil in the power cylinder will leak and mix in the material. Sometimes, the material will enter the hydraulic oil through the damaged sealing ring in the guide sleeve, polluting the hydraulic oil; affecting the user's use and causing economic losses. Summary of the Utility Model
[0003] The purpose of the present utility model is to provide an isolation cavity structure for a double-feed pump body working cylinder to reduce the mixing and pollution of material and hydraulic oil in view of the deficiencies in the above background art.
[0004] To achieve the above purpose, an isolation cavity structure for a double-feed pump body working cylinder of the present utility model adopts the following technical solutions:
[0005] An isolation cavity structure for a double-feed pump body working cylinder includes two symmetrically arranged working cylinders. A power cylinder is arranged between the two working cylinders. A piston rod is slidably arranged in the power cylinder. Pistons are arranged at both ends of the piston rod and are located in the working cylinders. An isolation plate is arranged in the working cylinder. There is a gap between the isolation plate and the power cylinder. A discharge port is further arranged below the gap between the isolation plate and the power cylinder. An overflow pipe is arranged on the isolation plate and communicates with the outside of the working cylinder.
[0006] A further improvement of the isolation cavity structure for a double-feed pump body working cylinder of the present utility model is that end faces of the power cylinder are arranged at both ends of the power cylinder, and an isolation cavity is formed between the end faces of the power cylinder and the isolation plate.
[0007] A further improvement of the isolation cavity structure for a double-feed pump body working cylinder of the present utility model is that the overflow pipe passes through the end face of the power cylinder.
[0008] A further improvement of the isolation cavity structure for a double-feed pump body working cylinder of the present utility model is that the working cylinder includes a front section and a rear section. The isolation plate is arranged in the rear section. The front section and the rear section, and the rear section and the end face of the power cylinder are connected by bolt members.
[0009] A further improvement of the isolation cavity structure for a double-feed pump body working cylinder of the present utility model is that the isolation plate is welded to the inner side wall of the rear section, and the overflow pipe is welded to the isolation plate.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] The utility model is provided with a partition plate for blocking the materials in the material cavity of the working cylinder. The partition plate blocks the contact between the materials and the end face and the guide sleeve of the oil cylinder. When the sealing rings on the partition plate or in the guide sleeve are worn out after a long service time, the hydraulic oil in the guide sleeve or the materials in the material cavity leak into the cavity behind the partition plate and are discharged from the oil-water discharge port below the working cylinder. By observing the oil-water discharge port, the sealing parts can be replaced in time to avoid the loss of hydraulic oil and the entry of materials into the hydraulic oil.
