Description
Technical field
The utility model relate to a kind of for heat supply, air-conditioning, water supply etc. greater than two with water pump as the be connected in parallel device of water pump of the field of transmitting power, belong to the water supply network equipment technical field.
Background technology
In the systems such as heat supply, air-conditioning, water supply, a large amount of water pumps that use supply water, and when determining to need the water pump quantity of use, need to consider following factor: or in order to increase system's water yield, or for system can move more flexibly, or be capital equipment of matching system etc.When many water pumps supply water, often adopt the mode of many water pump parallel connections to move.When in parallel, the Total Water of water pump certainly will be less than the flow sum of each water pump.At present the conventional way that is connected in parallel of water pump normally elbow or the threeway of water pump arm by 90 ° directly couple together.90 ℃ elbow or threeway are larger in the local resistance of water pump junction in actual use, cause the pressure at pump entrance place different, so that the pressure of exit of pump is also different, finally make the little pump capacity of pressure head little, even a water pump can appear opening more, the phenomenon that water yield increase is very little does not reach the anticipation effect of design and operation.
The utility model content
Technical problem to be solved in the utility model provides a kind of device of the water pump that is connected in parallel, and this device can reduce the resistance of threeway and water supply line junction, makes pump entrance pressure identical as far as possible, improves hydraulic stability and the pump efficiency of water pump operation.
The technical scheme that solves the problems of the technologies described above is:
A kind of device of the water pump that is connected in parallel, comprise water pump, water pump arm, threeway, vibration means for main pipe for supplying water, water outlet supervisor in its formation, its improvements are, vibration means for main pipe for supplying water and water outlet supervisor are reducer pipe, the diameter of vibration means for main pipe for supplying water reduces successively along the quantity of water supply direction according to threeway, and water outlet supervisor's diameter increases successively along the quantity of water outlet direction according to threeway.
The device of the above-mentioned water pump that is connected in parallel, the diameter of the two ends straight pipe of described threeway is different, wherein the diameter of an end is greater than the diameter of the other end, and transverse pipe is connected for inclination with straight pipe, and the axis of the axis of transverse pipe and straight pipe smaller diameter end is the angle of 15-25 degree.
The device of the above-mentioned water pump that is connected in parallel, the larger diameter end of the straight pipe of described threeway are connected with the larger diameter end of vibration means for main pipe for supplying water with the water outlet supervisor respectively, and smaller diameter end is connected with the smaller diameter end of vibration means for main pipe for supplying water with the water outlet supervisor respectively.
Usefulness of the present utility model is:
The utility model adopts the threeway that can reduce resistance to connect water pump, vibration means for main pipe for supplying water and water outlet supervisor are according to the uninterrupted reducing, to improve the hydraulic regime of pump entrance front and back, so that in the situation that as far as possible reduces local resistance loss, the flow velocity that the water pump supervisor enters each arm is identical, thereby make each exit of pump lift consistent, reduce the drag losses that brings thus, thereby improve system effectiveness.The utility model is novel in design, rational in infrastructure, hydraulic stability and pump efficiency that can the Effective Raise water pump operation.
