As shown in Figure 1, it is the disclosed a kind of mortar pump of Chinese patent ZL99208642.6, and this mortar pump comprises the pump housing, pump head, motor, speed changer, piston, spring and driving mechanism.The driving mechanism of this pump is made up of cam 2 and roller 3, and the output shaft of transmission of cam defeated 1 and speed changer 12 is same axises, and cam 2 touches movingly and connects roller 3, and the rocking arm of roller 3 connects the connecting rod 4 of piston movingly.This mortar pump is at the pulp mouth of pipe of pump head 11 and go out all conjuncted installing buffering pressure regulation tube 10 on the slurry check valve, pressure regulation tube 10 top load pressure gauges 9.Simultaneously, on pump head 11 lateral bodys, be provided with pressure-relief valve 13.Be provided with buffering pressure regulation tube 10 on this mortar pump, make that the pressure and the flow of this kind mortar pump output mortar are more stable, but, this kind mortar pump does not have voltage regulation function, the pressure of its output mortar is certain, and be uncontrollable, and needing to export the mortar of different pressures in using at the scene sometimes, obviously above-mentioned mortar pump is can not satisfy the needs of The field.
The model utility content
The purpose of this utility model provides a kind of controlled mortar pump of delivery pressure of mortar, and is single in order to the pressure that solves existing mortar pump output mortar, can not satisfy the requirement of the mortar of the multiple pressure of site of deployment needs.
For achieving the above object, the utility model adopts following technological scheme: the controlled mortar pump of a kind of pressure, comprise the piston type pump housing, the drive system of one-way valve and the reciprocal suction campaign of the driven plunger formula pump housing, the described piston type pump housing comprises material cylinder and the piston of slidable fit in the material cylinder, described one-way valve has feed cavity, discharging chamber and the suction material chamber that is communicated with the material cylinder, described drive system is a hydraulic driving system, this hydraulic driving system comprises drive motor and changement, described one-way valve is provided with the pressure gauge with electric contact that is communicated with the discharging chamber, and described pressure gauge with electric contact is by controller and drive motor control connection.
Described changement comprises the mechanical switching valve, the driveshaft that is in transmission connection on the reversing maneuver bar of mechanical switching valve, driveshaft is provided with adjustable two blocks of spacing, the position at two block places is the commutation working position, be provided with the commutation slide block that is connected mutually with the piston rod of oil hydraulic cylinder between two blocks, described slide block is stirred at the commutation working position with block and is cooperated.
Be provided with first valve between described feed cavity and the suction material chamber, be provided with second valve between described suction material chamber and the discharging chamber.
The controlled mortar pump of the pressure of such scheme, its one-way valve is provided with a pressure gauge with electric contact, pressure gauge with electric contact is used for monitoring the pressure in discharging chamber, when the pressure in the discharging chamber that pressure gauge with electric contact records during more than or equal to the setting value of pressure gauge with electric contact, pressure gauge with electric contact can send control signal to controller, the motion of controller control corresponding drive motor, make the piston type valve body stop the suction action, when the pressure in the discharging chamber during less than the setting value of pressure gauge with electric contact, electric contact pressure sends control signal to the controller table once more, the motion of controller control corresponding drive motor makes the piston valve body weight newly begin the suction action.According to this working principle, can realize the purpose that the mortar pump delivery pressure is adjustable by the setting value that changes pressure gauge with electric contact, satisfied the requirement of the mortar of the multiple delivery pressure of needs in the on-the-spot use.Also have, adopt hydraulic driving system, its control response is fast, and is highly sensitive, overcome the mortar pump of existing employing cam driving system, because of the machinery inertial of cam driving system is big, protects control, the problem of poor sensitivity by the manual identification pressure gauge.In addition, adopt hydraulic driving system, can control the reciprocating speed of oil hydraulic cylinder by the series flow control valve in the regulating system, and then the output flow of mortar is controlled.In sum, the mortar pump of this scheme has been realized mortar delivery pressure and the adjustable function of flow, has satisfied and has used on-the-spot different needs to mortar flow and pressure.
