Abstract
The utility model relates to the field of mechanical equipment, and in particular relates to a device for balancing a pump shaft of a rotary pump. The front end and the rear end of a main shaft of a shaft body are respectively provided with a sealing ring; the main shaft is provided with an angular contact bearing; the lower end of the main shaft is provided with a connecting shaft; the connecting shaft is provided with a sealing device; and the angular contact bearing is used for bearing the load of the shaft body along the positive axial direction and the negative axial direction, so that the load of a single bearing is reduced, the bearing is not easily damaged and is long in service life, and the operation is stable and reliable. The device is provided with the sealing rings and the sealing device, thus sealing effect is good; and the bearing is not easily damaged, so that the service life and the running stability of the bearing are improved.
Description
Technical field
The utility model relates to the machinery field, concretely, relates to a kind of pump shaft balancing device of rotary pump.
Background technique
Rotary pump sucks and discharges liquid by one or more rotor in pump, claims again rotor pump.
The form of rotary pump is a lot, but their operating principle is all similar.Comparatively commonly used in the chemical plant have gear pump and a screw pump.The feed flow of rotary pump can be controlled more accurately, is transferred material steady, and without destruction, rotating speed is low, and rotary pump can the transfer of highly viscous material, and the pressure head pressure head is higher, is fit to long square high-drag and quantitatively carries, and is simple in structure, easily unpicks and washes.Rotary pump is widely used in the fields such as power plant, oil, chemical industry, water purification, industrial and mining enterprise, food, pharmacy, papermaking, air-conditioning heating.
The pump shaft of rotary pump is provided with the pairing angular contact bearing, and axially positive and negative direction load relies on the pairing angular contact ball bearing to bear fully, and the pairing angular contact ball bearing is fragile, has a strong impact on normal operation.
The model utility content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of pump shaft balancing device of rotary pump.
Technological scheme to be solved in the utility model is as follows: a kind of pump shaft balancing device of rotary pump is made of seal ring, angular contact bearing, main shaft, axis body, coupling shaft, seal arrangement; The main shaft front end and back end of described axis body all has seal ring, and angular contact bearing is arranged on main shaft, and the main shaft lower end is coupling shaft, and seal arrangement is arranged on coupling shaft.
Described seal arrangement is two.
Described angular contact bearing is four.
Described angular contact bearing be 40 the degree angle.
The utility model has the advantage of: the main shaft front end and back end of axis body all has seal ring, and angular contact bearing is arranged on main shaft, and the main shaft lower end is coupling shaft, seal arrangement is arranged on coupling shaft, angular contact bearing is responsible for bearing the axial positive and negative direction load of axis body, has reduced the load of single bearing, and bearing is not fragile, long service life, turn round reliable and stable, have seal ring and seal arrangement, good sealing effect, bearing is not fragile, has improved working life and the operation stability of bearing.
