Abstract
The utility model relates to an adjusting device used for adjustment the oil outlet flow rate of an oil pump, which is characterized in that a screw hole is drilled at the side wall of the oil outlet and an adjusting screw is embedded in the screw hole, the axis of the adjusting screw is vertical to the axis of the oil outlet, a throughhole is arranged on the adjusting screw along the vertical direction of screw axis, the effective area of oil outlet channel can be changed by rotating the adjusting screw and the adjustment for the flow rate of oil pump oil outlet can be realized. The utility model has the advantages of simple operation and avoiding effectively the oil spillage phenomenon.
Description
Technical field:
The utility model relates to a kind of controlling device that is used to regulate oil pump oil outlet place flow.
Background technique:
Oil pump is an equipment commonly used in the industrial and agricultural production, in actual the use, because oil pump oil outlet place pressure is bigger, can produce the phenomenon of flow rate of liquid instability, oil spilling, cause unnecessary waste and contaminated equipment,, oil pump oil outlet place flow is controlled for avoiding these unfavorable consequences, using the oil port hydrodynamic pressure and be controlled by in the suitable scope, is the method for a practical.
Summary of the invention:
The purpose of this utility model is to provide a kind of controlling device that can regulate oil pump oil outlet place flow, so that oil pump oil outlet place flow is in controllable state.
For achieving the above object, this controlling device has installed an adjusting screw rod additional at oil pump oil outlet place, and the axis at the axis of this screw rod and oil pump oil outlet place is realized adjusting to oil pump oil outlet place flow by rotary screw in vertical state.
For reaching this kind effect, need make a call to a screw in the side-walls of oil pump oil outlet and the position of oil outlet axis normal, adjusting screw rod screws in thus; Adjusting screw rod with the screw axis Vertical direction on make a call to a through hole too.When adjusting screw rod was screwed into certain position, oil pump oil outlet axis overlapped with through-bore axis on the adjusting screw rod, and both constitute a passage, this moment this passage the useful area maximum, the oil pump capacity maximum of oil pump; The rotation adjusting screw rod, when through-bore axis on the screw rod and oil pump oil outlet axis in vertical state the time, the useful area of oil discharge passage is zero, the oil pump capacity of oil pump be a minimum, is zero.In this course, the flow of oil pump oil outlet can be selected a suitable flow as required, regulates in 90 ° angle, makes the flow smooth change, realizes the uninterrupted continuously of flow regulated.
When oil pressure changes, as required and field condition, adjusting screw rod is screwed in or screws out adjusting, in the angle of half-twist, can finish the adjusting of 0-100% flow.
This device for mechanical is simple in structure, the pump housing itself need not to do big change, only needing that the oil pump oil outlet is installed additional an adjusting screw rod can realize the uninterrupted continuously of flow regulated, make the oil pump oil outlet be in suitable pressure state, effectively avoided the excessive oil spilling phenomenon that causes of oil pressure, and operating process is simple and easy to do.
Description of drawings:
Fig. 1 is the top cross-sectional view of controlling device, and wherein 1 is adjusting screw rod screw-in position.
Fig. 2 is the front view of controlling device, and 2 is oil outlet.
Fig. 3 is the front view of adjusting screw rod.3 is through hole.
Embodiment:
A through hole is made a call in position in oil pump oil outlet side-walls and oil outlet axis normal, and adjusting screw rod screws in thus; Adjusting screw rod is being made a call to a through hole too with the screw axis Vertical direction.When adjusting screw rod was screwed into certain position, oil pump oil outlet axis overlapped with through-bore axis on the adjusting screw rod, and both constitute a passage, at this moment the oil pump capacity maximum of oil pump; The rotation adjusting screw rod, when through-bore axis on the screw rod and oil pump oil outlet axis in vertical state the time, the oil pump capacity of oil pump be a minimum, is zero.In this course, the flow of oil pump oil outlet can be selected a suitable flow as required, regulates in 90 ° angle, by changing the useful area of oil outlet passage, makes the flow smooth change, realizes the uninterrupted continuously of flow regulated.
Claims (1)
1, a kind of oil pump flow controlling device, constitute by oil pump oil outlet and an adjusting screw rod, it is characterized in that, this adjusting screw rod with the screw axis Vertical direction on a through hole is arranged, the side-walls of oil pump oil outlet with the direction of oil outlet axis normal on a screw is arranged, adjusting screw rod screws in screw, is assemblied in the oil pump oil outlet thus, and adjusting screw rod can rotate in the screw at oil pump oil outlet place.
