Water pump and engine

Abstract

The invention provides a water pump used for an engine. The water pump comprises a pump shell (3), a belt wheel (4), an inner integral ball bearing (5) and an impeller (6), and further comprises a pump base (1) fixedly connected with the pump shell (3). One side of the pump base (1) is provided with a thermostat installation plate (11) which is provided with a stepped groove (12) used for installation of a thermostat. The step of the stepped groove (12) is further provided with a locating groove (13) used for locating the thermostat. The step groove is formed in the thermostat installation plate and used for installing the thermostat so that the thermostat can further extend into the pump base. Water flowing out of holes of a warm water outlet pipe directly hits the thermostat, heat transfer temperature sensing is replaced, the temperature sensing effect is enhanced, and control is more accurate. In addition, the invention provides the engine comprising the water pump.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a water pump and an engine. Background technique [0002] In the prior art, the integral automobile engine water pump is commonly used. After the engine forms a vortex chamber through the pump housing integrated on the engine and the pump base, the cooling in the impeller channel will The liquid is thrown around, passes through the volute, and enters the cylinder body. A vacuum environment is formed at the inlet of the impeller. The coolant in the water tank is sucked along the suction pipe to replenish the formed vacuum space. The heated coolant in the cylinder body is pressed into the water tank. The coolant that enters the water tank will be cooled down and sucked into the cylinder block again, so that it circulates continuously to cool down the engine. [0003] However, in the actual production and application of this water pump, the thermostat should be opened reasonably to...

Problems solved by technology

[0003] However, in the actual production and application of this water pump, the thermostat should be opened reasonably to carry out the circulation of the water channel, which needs to be vacuumed thoroughly. The conditions are relatively harsh, which is not conducive to self-replacing the coolant. After self-replacement, the air is not easy to remove, and the water temperature of the engine is high; When the thermostat is in contact with the water pump, since there is no positioning device, the installation position of the thermostat is not easy to determine, which brings inconvenience to the installation process. The effect of the coolant is not accurate, resulting in high requirements for the production and assembly process
