Description
Technical field
This utility model relates to the filling and drainage system of a kind of engine cooling water temperature regulation system, the cooling water of the test equipment in Engine Block Test test chamber, is particularly conducive to engine test.
Background technology
At present, the filling and drainage system of engine cooling water temperature regulation system, generally use 2 water pumps and 2 valves to complete function: when system carries out water-filling operation, charging pump and filling valve are opened, and draining pump and drain valve are closed, and system carries out water filling process；When system carries out drain operation, draining pump and drain valve are opened, and jet water pump and filling valve are closed, and system carries out drainage procedure.
Owing to water-filling and drainage procedure are separate, system employs 2 set water pumps, occupies the inner space that stand is more, meanwhile, too increases fault rate and the maintenance cost of equipment.
If in the filling and drainage system of the engine coolant of stand, designed by pipeline cleverly and valve, only with a water pump, it is achieved that water-filling, drain function, its advantage is to have saved a water pump, decreases the installation space within stand, reduce the fault rate of equipment, save the maintenance cost of equipment.
Summary of the invention
The purpose of this utility model is to design the filling and drainage system of a kind of engine cooling water temperature regulation system, designed by pipe valve cleverly, with a water pump and 4 valves, realize water-filling, drain function integration, saves a water pump, saves the internal unit installing space of stand, reduce the fault rate of equipment, save the maintenance cost of equipment.
The technical solution of the utility model is achieved in that the filling and drainage system of engine cooling water temperature of the present utility model regulation system includes water-filling water tank, fills draining water pump, water-filling loop and draining circuit, water-filling valve and water discharging valve, if filling main sewer, the water inlet pipe of one end and engine cooling water temperature regulation system of filling main sewer is connected；Water-filling loop includes being sequentially connected with the first water-filling valve by the outlet of water-filling water tank, filling draining water pump, the second water-filling valve, and the second water-filling valve connects the other end filling main sewer；Draining circuit includes and fills the first row penstock that the main sewer other end is connected, the other end of first row penstock is connected to fill the pipeline between draining water pump and the first water-filling valve, and second row penstock is connected to the water inlet of water-filling water tank by the second water-filling valve and the pipeline that fills between draining water pump.
Advantage of the present utility model: this utility model is designed by pipe valve cleverly, realizes water-filling, drain function with a water pump and 4 valves, its advantage is to save a water pump, save the internal unit installing space of stand, reduce the fault rate of equipment, save the maintenance cost of equipment.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of this utility model cooling water temperature control system and filling and drainage system.
Detailed description of the invention
Structural representation if Fig. 1 is cooling water temperature control system and filling and drainage system:
Engine cooling water temperature regulation system includes cooling water circulation water pump 5, plate type heat exchanger 1, proportioning valve 2, heater 3, bypass valve 4, cooling water tank 6, tank intake valve of water 7, during cooling water circulation water pump 5,1 engine test of plate type heat exchanger, the heat of generation is taken away, passing ratio valve 2, heater 3, accurately adjusts water temperature.
Filling and drainage system includes water-filling water tank 13, fills draining water pump 9, water-filling loop and draining circuit, water-filling valve and water discharging valve, if filling main sewer 14, the water inlet pipe of one end and engine cooling water temperature regulation system of filling main sewer 14 is connected；Water-filling loop includes the first water-filling valve 10 being sequentially connected with by the outlet of water-filling water tank 13, fills draining water pump the 9, second water-filling valve 8, and the second water-filling valve 8 connects the other end filling main sewer 14；Draining circuit includes and fills the first row penstock 11 that main sewer 14 other end is connected, the other end of first row penstock 11 is connected to fill the pipeline between draining water pump 9 and the first water-filling valve 10, and second row penstock 12 is connected to the water inlet of water-filling water tank 13 by the second water-filling valve 8 and the pipeline that fills between draining water pump 9.
During engine test, water system passes through cooling circulating water pump 5, plate type heat exchanger 1, and the heat produced during engine test is taken away.Passing ratio valve 2, heater 3, accurately adjust water temperature.
When changing different electromotor, it is necessary to carry out filling draining:
When system water-filling, filling draining water pump 9 and operate, the second water-filling valve 8, the first water-filling valve 10 opens, water discharging valve 11, and water discharging valve 12 is closed, and water pump is electromotor water-filling from water tank；
Upon draining of the system, water pump 9 operates, water discharging valve 11, and water discharging valve 12 is opened, water-filling valve 8, and water-filling valve 10 is closed, water pump draining in water tank 6；
After electromotor completes water-filling and draining, water pump 9 stops, valve 8, valve 10, valve 11, valve 12 Close All, and now, coolant water temperature Ore-controlling Role works, and is accurately controlled the temperature of electromotor.
This utility model utilizes a water pump and the reasonable Arrangement of four valves, has reached water-filling and draining purpose.
