Definitions

  • the utility model belongs to the technical field of a plunger pump, and particularly relates to a plunger oil-free high pressure pump. Background technique
  • the plunger pump has been widely applied to various fields such as industry and life.
  • many cities a large number of washing machines, atomizers and the like are applied, and the pumps on the washing machine and the atomizer are the key components of the whole equipment.
  • the quality of the pump directly affects the efficiency of the entire equipment; the pumps on the existing cleaning machines and atomizers generally use oil-lubricated high-pressure pumps, which are used in the pump head and pump body. All kinds of lubricating oils or greases are used for lubrication. Lubricating oil and grease are used in the up and down movement of the plunger in the pump body.
  • the oil Once the oil is cleaned, it needs to be changed once a month after the maintenance period, and the energy consumption is large. 2.
  • the oil can be replaced to a certain degree of pollution to the environment. 3.
  • the sealing requirements are high.
  • the drive mechanism driven by the motor is composed of crankshaft and connecting rod.
  • the connecting rods are inconvenient to install on the crankshaft, which increases the production cost; 4. Improper installation can easily cause oil leakage damage caused by oil leakage.
  • the purpose of the utility model is to provide a plunger oil-free high-pressure pump which has simple structure, no pollution, high pressure, high efficiency, long service life and can operate without any lubricating oil or grease.
  • the pump head is mounted on the pump body, and a plunger pressurizing mechanism driven by the pump main shaft is installed in the pump body, and the plunger pressurizing mechanism is: at least two connecting rods are spaced apart and parallel to each other
  • the ground is coaxially disposed on the pump main shaft, one end of the connecting rod is disposed on the bearing, the bearing is fixed on the eccentric sleeve, the eccentric sleeve is fixed on the pump main shaft, and the other end of the connecting rod is hinged with the plunger.
  • the plunger is installed in the cavity of the pump body, and a self-lubricating plunger sleeve is arranged between the pump body and the plunger, and a sealing ring and a gasket are arranged at the contact portion between the end of the plunger and the pump head.
  • the connecting rod and the plunger are hinged to provide a groove opening at the joint of the plunger, and a bearing is arranged in the connecting hole of the connecting rod, and the connecting rod and the bearing thereon extend into the groove opening of the plunger and are hinged
  • the rods are connected.
  • the eccentric sleeve described above is positioned on the pump spindle by a shaft key.
  • the self-lubricating plunger sleeve described above is an engineering plastic.
  • the above-mentioned connecting rods are arranged on the pump main shaft at intervals on the eccentric sleeve between the adjacent two connecting rods.
  • the utility model uses the eccentric sleeve of the pump spindle to fix the eccentric sleeve instead of the multi-plunger crankshaft transmission, which is easy to manufacture, convenient to disassemble and assemble, and has low production cost.
  • the utility model is provided with a self-lubricating plunger sleeve at the contact portion between the pump body and the plunger, and the self-lubricating plunger sleeve has the characteristics of wear resistance, high temperature resistance and automatic lubrication of the plunger, so that the pump body of the utility model Without the use of various lubricating oils or greases, the plunger can move freely, saving energy and no pollution.
  • the plunger pressurizing mechanism of the utility model has three sets, which are driven by a pump main shaft, thereby improving the working efficiency of the device.
  • FIG. 1 is a schematic structural view of a transmission mechanism of the present invention
  • Figure 2 is a schematic view of the structure of the present invention.
  • the plunger has no oil high pressure pump, and the pump head 10 is mounted on the pump body 20.
  • the pump body 20 is provided with a plunger pressurizing mechanism driven by the pump main shaft 40.
  • the plunger pressurizing mechanism is: at least two connected
  • the rods 31 are coaxially disposed on the pump main shaft 40 at intervals and parallel to each other.
  • the connecting rod 31 ends are fixed on the bearing 50, and the bearing 50 is fixed on the eccentric sleeve 60, and the eccentric sleeve 60 is fixed on the pump main shaft 40.
  • the other end of the connecting rod 31 is hinged with the plunger 70.
  • the plunger 70 is installed in the cavity of the pump body 20.
  • a self-lubricating plunger sleeve 80 is disposed between the pump body 20 and the plunger 70.
  • a sealing ring 82 and a gasket 81 are provided at the contact portion of the end portion with the pump head 10.
  • the connecting rod 31 and the plunger 70 are hinged to provide a groove opening 71 at the joint of the plunger 70.
  • the connecting hole 72 of the connecting rod 31 is provided with a bearing 51.
  • the connecting portion of the connecting rod 31 and the bearing 51 thereon extend into the connecting rod 31.
  • the groove opening 71 of the plunger is connected by a hinge 90 plunger pin.
  • the above-mentioned connecting rod 31, the plunger 70 associated with the connecting rod 31, the self-lubricating plunger sleeve 80, the water sealing ring 82, the gasket 81 and the pump head 10 have three sets of plunger pressurizing mechanisms.
  • the eccentric sleeve 60 described above is positioned on the pump spindle 40 via the shaft key 91.
  • the self-lubricating plunger sleeve 80 described above is an engineering plastic.
  • the above-mentioned connecting rods 31 are spaced apart from each other on the pump main shaft 40, and a spacer collar 61 is sleeved on the eccentric sleeve 60 between the adjacent two connecting rods 31.
