Definitions

  • the invention relates to a pump drive for connection to a container pump or a container equipped with an integrated pump.
  • Such container pumps are used to convey liquids from containers, such as barrels or tanks.
  • a pump roughly consists of a pumping station and a pump head. The pumping station is introduced into the liquid to be pumped.
  • a rotor shaft rotates, which is assigned a rotor on the output side, and thus causes a vacuum in the pumping dome, so that the liquid in the pumping dome is sucked upwards.
  • the pumping station is followed by a withdrawal nozzle, through which the liquid conveyed upwards can be removed.
  • the sampling port is sealed off from the overlying pump head, so that the pumped liquid can not penetrate into the motor.
  • This connects above the pumping station. It comprises a drive whose shaft is operatively connected to the rotor shaft of the pumping station and which drives the pump.
  • a hose can be connected to the sampling nozzle to divert the liquid from the sampling nozzle.
  • a nozzle or a drain cock over which the process can be controlled.
  • the invention has for its object to provide a pump drive, which allows a simple and effective connection of the pump drive with a container pump and / or a container.
  • the pump drive is encompassed by a housing which has at least one handle.
  • This at least one handle actuates a locking mechanism which locks the pump drive after putting the motor on the interface of the pumping station with this.
  • the lock Upon actuation of the handle, the lock is disengaged and the pump drive can be positioned on the pumping station. Due to the fact that the motor is sometimes held on the at least one handle in the case of two-handed operation, no hand has to be used for opening and closing the bolt.
  • the pump drive is placed with the handle pressed, then the handle is released. This puts the lock in engagement with the pumping station, so that the pump drive can be released safely.
  • the pump drive according to the invention is usefully further developed in that the housing has two handles. As a result, the position of both hands is specified on the drive. Through a meaningful, even distribution the handles around the circumference of the housing, the weight of the pump drive is evenly distributed, so that the handling of the device simplifies and facilitates. Moreover, the user is thus stopped and encouraged to hold both hands in the designated positions so as to avoid pinching or coming in contact with the conveyed liquids.
  • the handles on a contact edge along which the handle rests in its locking position on the housing.
  • the handle has a rotating end and a locking end.
  • the rotating end is fixedly connected to the lock, which is pivotally connected via a rotation axis to the housing.
  • the locking end is detachably connectable to the housing.
  • a loop edge is rotatably connected to the housing wall, while the opposite loop edge is also rotatably connected to the handle.
  • the breakpoints of this loop are concealed behind the contact edge, since the handle has a recess in this area.
  • the breakpoints are also offset in the direction of the contact edge, so that when pivoting the handle rotation of the loop around both breakpoints occurs.
  • the unlocking state represents, the lock is disengaged, so that the pump drive can be inserted into the pumping station or removed from it.
  • the widest deflection of the handle is determined by the size of the loop, which aligns in the deflected state in the direction of force of a pulling force on the handle.
  • the applied state which is also the locking state, the lock is fixed and the drive can not be removed from the pumping station or flanged.
  • each handle a security lock is assigned.
  • This safety lock holds the handle in the locked state. This avoids accidentally opening the handles during operation and disengaging the running motor from the pump shaft, which can result in damage or injury.
  • each lathe must be rotatably mounted with respect to their point of attack in any way. However, it makes sense if this is done by the lock.
  • the pump drive When placing the pump drive on the pumping station, it may happen that the pump drive is not discontinued in the intended position on the pumping station. By twisting the pump drive relative to the pumping station, however, this position can be achieved. Only in the correct position, the handles can be brought into the locked position. If, for example, a polygonal recess on the pumping station ensured the torsional strength, the pump drive would possibly have to be replaced in a different position.
  • such a speed controller is positively integrated into the housing.
  • the rotary handle of this speed controller is arranged on the driver opposite side of the housing.
  • the hands are again kept out of the field of power transmission as far as possible.
  • the motor In order to protect the motor from both moisture and vibration, it is surrounded by a foam insert inside the housing. As a result, the engine is indeed connected to the case conclusive, but it is an elastic connection that largely absorbs occurring forces.
  • universal motors are used, the advantage is that they increase their torque at a speed reduction occurring due to loads and thus counteract the effect of slowing down. In addition, it can be operated with both direct current and alternating current, which makes it interesting for many different applications.
  • the pump drive is assigned a removal nozzle equal.
  • the engine can be used with a container pump, which consists only of a pumping station and dispenses with its own sampling nozzle.
  • container pumps integrated in containers have the advantage that the containers are easily stackable.
  • the integrated pumping stations are arranged in a deep-drawn well, so that the pump connections do not overlap the upper edge of the container.
  • the housing has an inlet opening through which air can be sucked from the outside.
  • the air is guided by a fan in an air channel formed from the housing and the foam insert to the motor top. From there, the air falls through the engine and then through the fan and is discharged via outlet openings. This allows an efficient delivery of heat to the cooling air and ensures a speedy removal of the heated air out of the housing.
  • FIG. 1 shows a pump drive, which has a housing 1 with two handles 4.
  • the handles 4 are arranged laterally opposite one another in the direction of the longitudinal extension of the housing 1. This makes it possible to handle the pump drive with two hands, to wear and also set up on a pumping station 9 with two hands.
  • the pump drive locks 3 which engage non-positively in corresponding recesses in the pumping station 9.
  • a driver 8 which is mounted on the drive shaft 2 of the motor 11 housing wall.
  • a rounded rotary handle 5 is arranged, which is a speed controller operated inside the case.
  • the speed of the motor 11 can be adjusted and thereby the engine power to the requirements, such as the viscosity, the density or the flow rate and - be adapted.
  • this recessed grip 7 Since the user of such pump drives usually wear work gloves, this helps in the operation of the drive. If the pump drive is now to be placed on a pumping station, the latches are disengaged by means of the handles 4, the drive is put on and the latches are brought back into engagement.
  • FIG. 2 This procedure shows FIG. 2 in which the pump drive with pivoted handles 4 is shown.
  • the handles 4 have a contact edge 13, along which they rest in their locking position on the housing 1.
  • One end of this contact edge 13 is a rotating end 14, the other is the free locking end 15.
  • the handles 4 are pivotally hinged to the housing 1 by means of swivel joints.
  • each handle 4 is assigned along an edge rotatably connected to the housing 1 metal loop with a rectangular opening cross-section. This loop is also rotatably connected to the respective handle 4 in such a way that the holding points of the loop are arranged behind the latter when the handle 4 is applied in the direction of the contact edge.
  • the locking end 15 can be detachably connected to the housing 1 by means of a latch 10 on the housing, or by means of a safety lock 6 on the handles 4.
  • the handle 4 with its locking end 15 are pivoted back from the housing 1.
  • the metal loop limits the deflection in such a way that the metal loop is aligned with the handle 4 completely swiveled away in the direction of the pulling force to be exerted for swiveling the handle 4.
  • the latches 3 are thus disengaged, so that the pump drive is placed in this state on the pumping station 9.
  • FIG. 3 shows the mounted on the 9 pumping pump drive.
  • the handles 4 are again applied to the housing 1, so that the latches 3 engage in the corresponding recesses of the pumping station 9.
  • the safety locks 6 are closed. This avoids accidental opening of the latches 3, which could lead to accidental tipping out of the possibly running pump drive from the receiving socket of the pumping station 9 and thus to damage.
  • FIG. 4 finally shows a sectional view of the pump drive.
  • the position of the motor 11 can be seen.
  • This is encompassed by a foam insert 12, which cushion it against the housing wall and at the same time forms an air channel with this.
  • Cooling air is sucked into the housing 1 via an inlet opening by means of a fan 16 through this air channel.
  • the air initially flows through this air duct in the direction of the upper side of the housing, so that it is located above the motor 11. From there, a cooling passage passes through the entire length of the engine 11. Below this cooling channel the fan 16 is arranged so that the air which has passed through the engine 11 can be discharged through it.
  • On the side facing away from the motor 11 of the fan 16 outlet openings 17 are present in the housing wall, via which the heated air leaves the housing 1.
