Description

Engine-driving centrifugal water pump is from cooling system
Technical field
The utility model belongs to pump technical field of auxiliary equipment, relates to a kind of engine-driving centrifugal water pump from cooling system.
Background technique
The centrifugal water pump that existing portable engine drives, what all adopt be forced air cooling mode is engine temperature reducing, to guarantee that engine works in rational temperature range.Fan is by bent axle Direct driver, and through wind scooper wind guided into the positions such as the cylinder that needs heat radiation and cylinder head to complete heat radiation, the fan turns of this radiating mode needs the power of consumption of engine to obtain.Motor also needs to arrange that larger radiating fin is to increase heat diffusion area, and cause volume to become large, weight increases.Forced air cold engine uses chilling temperature too low under also there is cold conditions, motor cannot reach normal temperature range, gasification of fuel oil efficiency and combustion efficiency is caused to reduce, power also reduces thereupon simultaneously, and carbonizing of engine can be caused too much, destroy the sealing effect of piston ring and rational compression ratio.Need to increase manual maintenance number of times, otherwise machine performance can be reduced or damage machine, use when heat and there is heat radiation deficiency, temperature is too high cause power rapidly under, fall so that the appearance of fault, therefore, the fan rotated with crankshaft-synchronous to ensure that motor obtains optimum working temperature when severe cold and heat.
Model utility content
The utility model provides a kind of engine-driving centrifugal water pump from cooling system, to solve the cooling problem of centrifugal water pump, improves the cooling effect of motor, reduces energy ezpenditure, reduce maintenance cost.
The technical solution of the utility model is, engine-driving centrifugal water pump, from cooling system, comprises the pump housing, support, cylinder and cylinder head, and the pump housing and cylinder are connected, and cylinder head is positioned at the top of cylinder.Be provided with from cooling system and cool back water pipe and cool water pipe.The pump housing is provided with backwater entrance and coolant outlet.Cylinder head is provided with cooling water inlet and backwater outlet.Cool back one, water pipe to export with backwater and be connected, one is connected with backwater entrance.Cooling carrys out one, water pipe and is connected with cooling water inlet, and other end is connected with coolant outlet.
Cooling back water pipe and cooling water pipe is around property Stainless Steel Tube, rubber pipe or plastic tube.Be provided with paraffin thermostat from cooling system, coolant outlet carrys out water pipe by cooling and is connected to paraffin thermostat entrance, and the outlet of paraffin thermostat is connected to cooling water inlet.
The utility model engine-driving centrifugal water pump carrys out water pipe and cools back water pipe to set up cooling circuit between cylinder head and the pump housing by cooling from cooling system, realize the automatic cooling to motor, utilize the pressure reduction in water pump to make water flow through cylinder head to dispel the heat, there is no power loss, be conducive to reducing energy ezpenditure.Use the utility model cooled engine, cut the parts such as fan, radiating fin, connected element, wind scooper, alleviated pump housing weight, easy to carry and transport.Water route series connection paraffin thermostat, can make engine work in optimum temperature range.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model engine-driving centrifugal water pump from cooling system;
Wherein:
1-support, 2-cylinder head, 3-cool back water pipe, 4-cooling come water pipe, 5-pump case, the outlet of 6-backwater, 7-cooling water inlet, 8-backwater entrance, 9-coolant outlet, 10-cylinder.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.The utility model protection domain is not limited to embodiment, and those skilled in the art make the scope that any change also belongs to the utility model protection in the scope that claim limits.
The utility model engine-driving centrifugal water pump from cooling system as shown in Figure 1, comprises the pump housing 5, support 1, cylinder 10, cylinder head 2, cools back water pipe 3 and cool water pipe 4.The pump housing and cylinder are connected, and cylinder head is positioned at the top of cylinder.Cooling back water pipe 3 and cooling water pipe 4 is around property Stainless Steel Tube.The pump housing is provided with backwater entrance 8 and coolant outlet 9.Cylinder head is provided with cooling water inlet 7 and backwater outlet 6, is provided with cooling channel, cooling channel and cooling water inlet and backwater outlet in cylinder head.Cool back one, water pipe to export with backwater and be connected, one is connected with backwater entrance.Cooling carrys out one, water pipe and is connected with cooling water inlet, and other end is connected with coolant outlet.
Engine-driving centrifugal water pump vane rotary, water is subject to centrifugal action and is thrown out of impeller, impeller central forms negative pressure, extraneous water water under barometric pressure effect is pressed into suction sleeve and enters impeller, be subject to again the impeller action of High Rotation Speed, be thrown out of impeller and enter outlet conduit, go round and begin again and reach the object of pump water.
Water pump vane operationally, water route not termination of pumping water, the outer rim pressure of centrifugal impeller is high, near impeller central, pressure is low, there is larger pressure reduction, according to this characteristic, select high low pressure two place respectively to establish a pipeline, water endlessly being guided into motor needs the cylinder cap of heat radiation and cylinder position to realize the object of cooling.Air thermal conductivity is at normal temperatures 0.026, and the thermal conductivity of water is 0.62, and the coefficient of heat transfer of water is 23.84 times of air, utilizes the water-cooled effect that water pump water flows through cylinder head to significantly improve than air heat dissipation rate.
