Hegemonic power pump will batch produced in zhejiang r&d has been very successful

The goal of the initiative is to communicate the deficiency of existing skills and provide a way to use cylinder vacuum suction type fire power station pump electric pump body, its use their cylinder body tightly compressed structure to carry out the suction drainage, do not need to add smoke exhaust oxygen inside the vacuum pumps installation, suction, high pressure, large Yang Chengyuan help senior strengths.

Skills things referenced solution is:

Cylinder type electric pump body, including housing, crankshaft, connecting rod, cylinder block parts, check valve, pressure pipe, outlet pipe, fittings, pressure release valve joint.

Specific implementation, will use the dynamics, the up and down movement of a cylinder and one-way valve of the tacit understanding to carry out the water and drainage.

1. The facility at least refer to two cylinder above, using the up and down movement of cylinder suction and thrust to fluid intake and withdraws from the partnership.

Between 2. The cylinder head and the suction pipe, outlet pipe are connected by a one-way valve, when the cylinder inwards to narrow a check valve on the suction tube fluid intake and outlet side automatically closed, when the cylinder pushing outward bibulous imported automatic check valve failure forced to outlet suction fluid outlet check valve open at this time will be derived fluid, overturned action constitutes a row of the cycle of chain.

(3) at the outlet is equipped with pressure relief valve, when the water inlet at the suction pipes and pumps the water body can pass attached in advance when I get the water pressure increasing good relief valve will draw off, so you can embankment water pressure beyond a brigadier general facilities may damage the water pressure.

4. At the water inlet is laden with exhaust switch, open the switch in front of the facilities to start with the outside world made appear to make oxygen insertion, embankment feed line starting difficulty, begin a new line into the water growth after the electric pump to start the requirements to work up the collapse of the exhaust gas switch forced suction inlet pipe water suction.

5. Positive and negative pressure gauge, the positive pressure gauge and outlet connection to observe the positive pressure working conditions, the negative pressure gauge and pressure pipe connection to observe the condition of pressure pipe leakage, the positive and negative pressure gauge is installed on the appropriate coordinate in order to observe the stress status, through the reasonable connection of the above parts into a complete cylinder type fire pumps. The fire pumps skills of initiative will overthrow the crowd must be called upon to pump impeller can absorb water concept of thinking, simple pump cylinder type water power station in operation at the same time will greatly mobilize of each function.

Specific coefficient is as follows: (if you have little control in control after data)

Vertical bibulous ply 20 meters, take quick connectors;

Suction style cylinder, not vacuum pumps installation;

Power 20 ps, 3600 / min speed;

Vertical 20 meters water time 10 seconds;

Positive pressure pressure 3.5 MPa, Yang Cheng 300 meters;

Inlet pipe oral arm 80 mm, water oral arm is 65 mm;

Startup mode: manual, electric;
