"SINGLE CYLINDER DOUBLE ACTING, RECIPROCATING SUBMERESIBLE PUMP"

Abstract A single cylinder, double acting, reciprocating submersible pump comprising: - a cylindrical housing (1), the upper end of said housing being connected to a collector (10) through a pipe means, - a water jacket (2) surrounding the said housing, - two inlet ports on one of the vertical walls of said housing and water jacket, each of said port placed close to the upper and lower ends of the said houlsing respectively, the said inlet ports having suction valves (3,4) to permit entry of water from outside to inside of said housing, - two outlet ports (3,4) placed opposite the inlet ports on the opposite inner vertical wall of said housing for allowing the entry of water into the water jacket, each of said outlet port having delivery valves. - a piston placed within said housing connected to the handle of the pump by a piston rod.
Full Text The present invention relates to single cylinder, double acting, reciprocating submersible pump.
BACKGROUND
The prior pumps are either with two cylinders and pistons or a single cylinder with single piston. There are many disadvantages of these pumps. In double cylinder pumps the cost is higher and these pumps are unable to lift the water after a definite depth because separation will start after that particular depth. Similarly single cylinder, double acting pump is unable to lift the water after a particular depth.
The object of the present invention is to provide a pump so that there is no problem of water separation after a definite depth.
Another object of the present invention is lift water from any depth.
Yet another object of the present invention is that the discharge is approximately double from the prior single acting reciprocating pumps.
Accordingly the present invention describes a single cylinder, double acting, reciprocating submersible pump comprising
- a cylindrical housing, the upper end of said housing being connected to a collector through a connecting means, a water jacket surrounding the said housing,

two inlet ports on one of the vertical walls of the housing, each of said port placed close to the upper and lower ends of the said housing, the said inlet ports having suction valves to permit entry of water from outside to inside of the housing,
- two outlet ports placed opposite the inlet ports on the opposite wall of the housing for allowing the entry of water into the water jacket, each of said outlet port having delivery valves,
- a piston placed within the housing connected to the handle of the pump by a piston rod.
The length of the stroke is 230 mm.
The bore of the cylinder is 55 mm.
The discharge of water per cycle is approximately 1000 cm3 per cycle.
The present invention will now be described with reference to the accompanying drawing:
Figure 1 shows the submersible pump according to the present invention
Referring to the drawings, in figure 1, a cylindrical housing 1 is provided which is enclosed in a water jacket 2. Each vertical side of the cylinder has two inlet and outlet ports each (3,4,5 and 6). The inlet ports having suction valves (6, 7) and the opposite vertical wall having two delivery (8 and 9) valves. Each of said suction and delivery valves being positioned close to the upper and lower end of the cylindrical housing respectively.

The upper end of the cylinder is connected to a collector 10 by means of a pipe 11. Within the cylindrical housing is placed a piston 12 which is connected to a handle 13 by means of a piston rod 1.4.
WORKING
When the piston 12 goes down the suction valve 6 opens and water enters into the cylinder 1 from the well through this valve. When the piston goes up water enters into the cylinder in lower side of the piston through the suction valve 7 and the water entered into the cylinder in the previous stroke, goes outside from the cylinder through the delivery valve 8 (as this valve opens during upward stroke).
The delivery valve 9 and suction valve 6 remain closed during upward stroke. Similarly in the downward stroke the suction valve 6 and delivery valve 9 open and water enters into the cylinder above the piston and at the same time the water goes outside from the cylinder (through delivery valve 9) which was sucked during the upward stroke below the piston. The water, which is, delivered through the delivery valve 8 and 9 raises in the water jacket and it goes to the collector through a pipe and it flows outside from the collector through a tap. We can also provide a space for delivery of water from the cylinder through delivery valves by two cylinder liners of different diameters in place of water jackets in a single cylinder. In this way we get a continuous flow of the water or any other fluid.




We claim:
1. A single cylinder, double acting, reciprocating submersible pump
comprising:
- a cylindrical housing (1). the upper end of said housing being connected
to a collector (10) through a pipe means,
a water jacket (2)surrounding the said housing,
two inlet ports on one of the vertical walls of said housing and water jacket each of said port placed close to the upper and lower ends of the said housing respectively, the said inlet ports having suction valves (3,4) to permit entry of water from outside to inside of said housing,
- two outlet ports (3,4) placed opposite the inlet ports on the opposite inner vertical wall of said housing for allowing the entry of water into the water jacket, each of said outlet port having delivery valves,
- a piston placed within said housing connected to the handle of the pump by a piston rod.

2. A submersible pump as claimed in claim 1 wherein the length of the stroke is 230 mm.
3. A submersible pump as claimed in claim 1 wherein the bore of the housing is 55 mm.
4. A submersible pump as claimed in claim 1 wherein the discharge of water per cycle is approximately 1000 cm3 per cycle. .

5. A single cylinder, double acting, reciprocating submersible pump substantially as herein described with reference to the accompanying drawing.
