Abstract
The utility model discloses the improvement for a hand water pump used by families in the countryside. The utility model is characterized in that a sealing water chamber, a cylinder sleeve and a base are connected to form a sealing whole body through four fixed rods on the base and nuts; a water lifting rod drives a rubber piston to move in the cylinder sleeve from top to bottom, which can lead water to be lifted highly. The utility model has the advantages of low manufacturing cost, convenient usage, energy saving, labor saving, etc.
Description
The utility model relates to a kind of improvement of handlance pump, is mainly used in rural households' high-lift water lift of motor-pumped well.
Drink popularizing of water tower along with rural area family is small-sized, the peasant presses for a kind of high-lift pump.At present, piston type domestic water pump mainly contains two types, and a kind of is general expression handlance pump (seeing accompanying drawing 1), owing to this type of water pump hydroecium opens wide, thereby does not just possess high-lift this function; Another kind is an electric pump, is about to electric pump and places the motor-pumped well bottom, utilizes the high-lift water lift of electric power, but because voltage instability usually can cause electric pump to damage, and keeps in repair very inconveniently, thereby the application of electric pump also is subjected to certain restriction in the reality.
The utility model purpose just provides a kind of sealed type handlance pump, and it is to develop to form on the basis of former general expression handlance pump, has high-lift, cheap, energy and labour saving, plurality of advantages such as easy to use.
The utility model mainly is made of sealing hydroecium, cylinder sleeve, base, backwater envelope, rubber piston, water lifting rod, rocking handle, suction sleeve, outlet pipe etc.It is whole that sealing hydroecium, cylinder sleeve and base connect into sealing by four fixing rods on the base through nut, and sealing hydroecium top has a threaded water injection hole, is sealed by screw rod.Have a circular apertures in the middle of the base, the bottom surface, hole links to each other with suction sleeve, and the hole end face is covered by water seal, and suction sleeve or susceptor surface have a threaded exhaust port, communicate with cylinder sleeve, and exhaust port is by bolt seal.Have rubber piston and a water lifting rod identical with its internal diameter to be fixed together in cylinder sleeve, water lifting rod drives piston and can move up and down in cylinder sleeve, and water lifting rod is upward through the sealing hydroecium, in the sealed circle sealing in the contacting point of water lifting rod and sealing hydroecium.The water lifting rod top is connected with connecting rod, and connecting rod and rocking handle are linked together by the fixing frame on the sealing hydroecium, shake rocking arm, drives water lifting rod by connecting rod and moves up and down.Side at the sealing hydroecium has a water outlet, links to each other with outlet pipe, and outlet pipe is connected to threeway, and a valve is installed, and can control the flow direction of water.

Contrast accompanying drawing below, the utility model is explained in detail.
The utility model is mainly by sealing hydroecium (1), cylinder sleeve (2), base (3), backwater envelope (8), rubber piston (5), water lifting rod (4), rocking arm (16), suction sleeve (6), outlet pipe formations such as (11).It is whole that sealing hydroecium (1), cylinder sleeve (2) and base (3) connect into sealing by four fixing rods (9) on the base (3) through nut (10), and sealing hydroecium (1) top has a threaded water injection hole (14), by bolt seal.Have a circular apertures in the middle of the base (3), the bottom, hole links to each other with suction sleeve (6), and the hole end face is covered by backwater envelope (8), and there is a threaded exhaust port (7) on suction sleeve (6) or base (2) surface, communicate with cylinder sleeve (2), and exhaust port (7) is by bolt seal.In cylinder sleeve (2), there be a rubber piston (5) identical to be fixed together with a water lifting rod (4) with its internal diameter, water lifting rod (4) drives piston (5) and can move up and down in cylinder sleeve (2), water lifting rod (4) is upward through sealing hydroecium (1), in the sealed circle in contacting point (17) sealing of water lifting rod (4) and sealing hydroecium (1).Water lifting rod (4) top connects with connecting rod (15), and connecting rod (15) and rocking arm (16) are linked together by the fixing frame on the sealing hydroecium (1).Side at sealing hydroecium (1) has an outlet pipe (11), and outlet pipe (11) is connected to threeway, and its horizontal outlet pipe is installed a valve (12), can control the flow direction of water.During use, handlance pump is placed the motor-pumped well top, suction sleeve (6) is placed the motor-pumped well bottom, water is injected sealing hydroecium (1) and uses bolt seal along water injection hole (14), shake rocking arm (16), driving water lifting rod (4) by connecting rod (15) moves up and down along cylinder sleeve (2) inwall, under the effect of pressure, water is washed backwater envelope (8) open through suction sleeve (6) and is entered sealing hydroecium (1), because whole water pump system seals, thereby water discharges through outlet pipe (11) with high pressure, and twisting valve (12) can be controlled the flow direction of water.For avoiding destroying because of temperature sharp fall may cause water pump, can breakdown exhaust port (7), water is just return in the well automatically.
Claims (5)
1, a kind of rural households handlance pump comprises sealing hydroecium, cylinder sleeve, threeway, valve etc., and it is characterized in that: it is whole that four fixing rods on sealing hydroecium, cylinder sleeve and the base connect into sealing through nut.
2, handlance pump according to claim 1, it is characterized in that: outlet pipe is connected to threeway, and its horizontal outlet pipe is equipped with valve.
3, handlance pump according to claim 1 is characterized in that: suction sleeve or susceptor surface have a threaded exhaust port, communicate with cylinder sleeve, and exhaust port is by bolt seal.
4, handlance pump according to claim 1 is characterized in that: a threaded water injection hole is arranged at sealing hydroecium top, by bolt seal.
5, handlance pump according to claim 1 is characterized in that: sealing hydroecium and water lifting rod contacting point seal with seal ring.
