Description

Technical Field

[0001] The invention relates to the technical field of industrial pumps, and in particular to an industrial pump body protection device and a use method thereof. Background Art

[0002] With the rapid development of industrial technology, industrial pumps, as key equipment for fluid transportation, play an indispensable role in many industries such as chemical, petroleum, metallurgy, and electric power. However, during the operation of industrial pumps, the pump body often faces various severe working environments, such as high temperature, high pressure, corrosive media, and scouring of solid particles. These factors seriously threaten the safe and stable operation of the pump body, and even cause damage to the pump body, affecting production efficiency and equipment life. Therefore, a protective shell is often set outside the industrial pump to protect the industrial pump. However, the existing protective device for the pump body of the industrial pump has the following problems when used:

[0003] When an industrial pump is in use, it is connected and driven by the rotating shaft between the pump body and its driving motor. A bearing is often set in the rotating shaft to carry the rotating shaft. Since the motor drives the rotating shaft to rotate at high speed, the lubricating oil in the bearing will also be consumed. Therefore, the bearing of the rotating shaft needs to be maintained frequently.

[0004] Since industrial pumps are often provided with a protective shell as a protective device on the outside to prevent high temperature, high pressure, corrosive media and solid particles from affecting the industrial pumps, when maintaining the industrial pumps, the protective shell needs to be removed first, and then the oil filling port on the industrial pump can be maintained on the rotating shaft. In addition, the current industrial pump protective shells often use multiple sets of bolts and nuts to match the protective device to the industrial pump, which is more cumbersome during disassembly and installation. In order to ensure that high temperature, high pressure, corrosive media, etc. will not affect the industrial pumps, their protective devices are often relatively closed, which greatly affects the heat dissipation capacity of the industrial pump drive motor and its pump body, so improvements are needed.

A method for using an industrial pump body protection device according to any one of claims 1 to 6, characterized in that: The specific steps include: Step 1: First, connect the second oil filling pipe (607) of the oil filling assembly to the oil filling port (5), then lift the movable clamping rod (701), and align the first protective shell (1) and the second protective shell (2) with the pump body (3) and the drive motor (4), clamp the first protective shell (1) and the second protective shell (2) on the surfaces of the two, and at the same time, make the clamping block (703) on the movable clamping rod (701) pass through the inner side of the clamping ring (704), then lower the movable clamping rod (701), and directly install the mounting bolts through the first through hole (702), the second through hole (706) and the fixing hole (10) to fix the first protective shell (1) and the second protective shell (2); Step 2: When the first protective shell (1) and the second protective shell (2) are installed and combined, the hollow plug (806) is inserted into the socket (805), so that the first cavity (801) and the second cavity (802) are connected. At this time, the water inlet (803) can be used to connect external cooling water, so that the cooling water passes through the first protective shell (1) and the second protective shell (2) to cool the drive motor (4) and the pump body (3), and then flows back out through the reflux port (804); Step 3: Finally, when the rotating shaft between the driving motor (4) and the pump body (3) needs to be refilled with oil for maintenance, firstly, grease is added to the oil storage cylinder (601) through the refueling port (604), and then the electric telescopic rod (602) drives the plunger (603) to push the grease in the oil storage cylinder (601), and then the grease is diverted to each second oil filling pipe (607) through the first oil filling pipe (605) and the one-inlet and multiple-outlet solenoid valve (606), and then oil is filled into the oil filling port (5) to refill the rotating shaft support bearing.
