Description
Technical field:
The present invention relates to pumping plant, be specially adapted to externally-connected jet device with preposed water pump.
Background technique:
When centrifugal or Scroll-tupe water pump draws water, must on pump intake, be communicated with a preposition water injecting device by pipeline, this water injecting device structure connects water injecting pipe by one-way valve and forms, start preceding from pump outlet toward the water pump water filling, make fills with water in the water injecting pipe, and water surface elevation to flood the propeller cavitation of water pump.Starting mode of pump rear screw shaft place has water can take out the generation negative pressure like this, and water column just can follow up in the water injecting pipe, and water column rises and produces the one-way cock that negative pressure is communicated with the water injecting pipe lower end and open in the water injecting pipe, then is submerged in the pond one-way valve inflow water pump that just can constantly supply water.During the water pump stall, one-way valve is closed automatically and is made water pump propeller cavitation place keep enough water levels, if then restart propeller cavitation because of this water level of a variety of causes when not enough, then only can dally, and water filling could normally start once more.
This water injecting device structure does not produce the effect that improves pump head.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of externally-connected jet device with preposed water pump is provided.
The solution of the present invention is: liquid jetting device is made up of fluid director, jet mouth, jet pipe, jet pipe is body in a tubular form, its underpart is the step cylindrical shape, step cylindrical body underpart is an outside thread, jet pipe inner chamber bottom is a cone shape hole, and the cone shape hole upper end is one section cylindrical hole, and the cylindrical hole upper end is a reverse taper hole, the reverse taper hole upper end is a step hole, and this step hole inwall is an internal thread; Jet mouth bottom gabarit is the step cylindrical body, step cylindrical body bottom is an outside thread, jet mouth top gabarit is a taper, jet mouth inner chamber bottom is short circular hole, short circular hole upper end is a cone shape hole, behind the jet pipe installation in position, jet mouth upper-end surface is positioned at the central region in space, jet pipe inner chamber lower taper hole; The fluid director gabarit is a tubular body, the underpart is provided with the outside thread of corresponding connection with one-way valve, the internal thread that the upper end portion is provided with is realized being threaded with jet pipe underpart outside thread, fluid director middle part sidewall has a hole and to the both sides L type tubular body that respectively extends, two L type tubular bodies are formed a U type pipe, the U type pipe outside vertically is provided with the internal thread that connects corresponding to the water injecting pipe outside thread in the pipe upper end portion, U type pipe inboard vertically pipe and the same shaft axis of fluid director gabarit tubular body, this inboard is vertically managed the internal thread of upper end portion setting and is realized being threaded with jet mouth underpart outside thread.
The invention has the advantages that: utilize and draw back water on the water pump and enter liquid jetting device and produce jet, cause high negative pressure, water injecting device water column upflow velocity is strengthened, the flow velocity of water pump water inlet just causes water flow velocity greatly and strengthens, strengthen once more and go out the also related liquid jetting device backwater flow velocity that enters of water flow velocity increasing, form optimum speed-raising circulation, thereby greatly improve pump head.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Structure of the present invention is characterized in that: be made up of fluid director (2), jet mouth (3), jet pipe (4), jet pipe (4) is body in a tubular form, its underpart is the step cylindrical shape, step cylindrical body underpart is an outside thread, jet pipe (4) inner chamber bottom is a cone shape hole, and the cone shape hole upper end is one section cylindrical hole, and the cylindrical hole upper end is a reverse taper hole, the reverse taper hole upper end is a step hole, and this step hole inwall is an internal thread; Jet mouth (3) bottom gabarit is the step cylindrical body, step cylindrical body bottom is an outside thread, jet mouth (3) top gabarit is a taper, jet mouth (3) inner chamber bottom is short circular hole, short circular hole upper end is a cone shape hole, behind jet pipe (4) installation in position, jet mouth (3) upper-end surface is positioned at the central region in space, jet pipe (4) inner chamber lower taper hole; Fluid director (2) gabarit is a tubular body, the underpart is provided with the outside thread with the corresponding connection of one-way valve (1), the internal thread that the upper end portion is provided with is realized being threaded with jet pipe (4) underpart outside thread, fluid director (2) middle part sidewall has a hole and to the both sides L type tubular body that respectively extends, two L type tubular bodies are formed a U type pipe, the U type pipe outside vertically is provided with the internal thread that connects corresponding to the water injecting pipe outside thread in the pipe upper end portion, U type pipe inboard vertically pipe and the same shaft axis of fluid director (2) gabarit tubular body, this inboard is vertically managed the internal thread of upper end portion setting and is realized being threaded with jet mouth (3) underpart outside thread.
Owing in water injecting device, insert the external coupling type liquid jetting device, backwater is upwards sprayed by jet mouth (3) through U type pipe, the current that come up at jet pipe (4) lower taper hole area of space and one-way valve (1) form and conflux, and drive is confluxed by short circular hole formation high-velocity flow, this high-velocity flow rises to the inverted cone pipe of jet pipe (4) inner chamber top divergent contour, forms to expand the stream effect.This expands the stream effect and also just produces high negative pressure, and the current that impel one-way valve (1) to come up quicken.Water pump (5) influence that flow velocity strengthens of being supplied water, its lift must improve, and water pump (5) water outlet flow velocity improves makes the return pipe flow velocity improve again, thereby produces optimum speed-raising circulation, in like manner improves lift and also can carry high suction depth.
