Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes.
The invention provides fluid pressure type diving land reclamation pump, its operation principle is to drive main shaft by using variable hydraulic motor Rotate, realize the rotation of impeller, simplify equipment, reduce weight of equipment, it is stifled existing to avoid the occurrence of particle pump using unshrouded impeller As setting delivery port by the tail end in pump head, reduce the pump housing floods height, reaches and mitigates weight of equipment, reduces operation Difficulty, reduction water pump flood height, avoid pump stifled and improve the purpose of the operating efficiency of body.
With reference to embodiment and embodiment, the present invention is further detailed explanation.
As shown in figure 1, a kind of fluid pressure type diving land reclamation pump, includes pump head 1, the head end of the pump head is fixedly connected with change Hydraulic motor 2 is measured, is provided with main shaft 3 inside the pump head, one end of the main shaft is fixedly connected with the variable hydraulic motor, institute State pump head and circumference water inlet 4 is distributed with, the circumference water inlet is in 360 ° of circle distributions relative to the main shaft, the pump head Tail end is provided with delivery port 5, and the main shaft is provided with unshrouded impeller 6.
The present invention drives main axis by using variable hydraulic motor, realizes the rotation of impeller, simplifies equipment, reduces Weight of equipment, avoid the occurrence of particle pump using unshrouded impeller and block up phenomenon, delivery port is set by the tail end in pump head, reduced The pump housing floods height, reaches and mitigates weight of equipment, reduce operation difficulty, reduce water pump and flood height, avoid pump stifled and improve The purpose of the operating efficiency of body.
It is worth noting that, the tail end of the main shaft is cased with water lubriucated bearing 7.The tail end of main shaft is honoured using water lubrication shaft Protected.
It is worth noting that, the main shaft is provided with mechanical seal 8 and oil sealing 9.Edge is prevented using mechanical seal box oil sealing Main shaft is revealed, and is avoided the occurrence of gas leakage, be ensure that the water suction power of the pump housing, ensure that the work quality of the pump housing.
It is worth noting that, the water inlet goes out provided with intake end cover 10.Avoid inflow excessive using intake end cover and The pump housing is caused to damage.
It is worth noting that, the middle part of the lateral wall of the pump head and head end are additionally provided with double-row angular contact bal bearing 11.Profit The pump housing is born the power of axially and radially both direction with double-row angular contact bal bearing, also make the pump housing is alternative to carry out vertically Install or be horizontally mounted.
It is worth noting that, the material of the pump head is aerolite material.By using aerolite material system Make pump head, reduce the weight of the whole pump housing, make the pump housing easy to remove and adjust.
The specifically used step of the present invention is as follows：Again as shown in figure 1, in actual use, variable hydraulic motor（Tool Standby high rotating speed, low torque characteristic）Drive shaft 3 rotates, and drives unshrouded impeller 6 to rotate, the effect of variable hydraulic motor is by liquid Pressure produces driving torque, and as the power source of water pump, medium is after circumference water inlet 4 enters the import of unshrouded impeller 6, by equably It is oriented to unshrouded impeller 6.The unshrouded impeller 6 of rotation drives medium synchronous rotary, simultaneously because blade rotates, the medium on blade top Flow velocity will increase, and the flow velocity of bottom will reduce, and according to bernoulli's equation, the big local pressure of flow velocity is small, and flow velocity is small Local pressure is big.Due to the thrust that the change of this speed around blade and pressure has just produced a kind of upwards, this power is referred to as Lift, medium is then as this strand of lift enters in pipe network.
, more than by way of, fluid pressure type provided by the present invention is dived under water land reclamation pump, by using variable hydraulic motor band Dynamic main axis, realizes the rotation of impeller, simplifies equipment, reduce weight of equipment, particle is avoided the occurrence of using unshrouded impeller Pump blocks up phenomenon, and delivery port is set by the tail end in pump head, and reduce the pump housing floods height, reaches and mitigates weight of equipment, drop Low operation difficulty, reduction water pump flood height, avoid pump stifled and improve the purpose of the operating efficiency of body.
Above-described is only the preferred embodiment of fluid pressure type diving land reclamation pump disclosed in this invention, it is noted that For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, some changes can also be made Shape and improvement, these belong to protection scope of the present invention.
