Water level in the feed cistern 2 remains on the 1000mm of 6 tops, ground usually; Therefore the water inlet and being higher than that is higher than the water inlet trunk line 71 of cooling water recirculation system of the water level in the cistern is connected the water inlet of the water pump that respectively cools off branch road 9 92 on the water trunk line 71 into; Therefore the water level in the feed cistern 2 can make water pump 92 obtain sufficient low-pressure water, and water pump 92 need not aspirate when starting and just be full of low-pressure water; Its technique effect, the one, compare the power consumption that has reduced water pump with the drawing-in type cistern of present employing.The 2nd, the water level in feed cistern 2 can make the water inlet of water pump 92 remain at very sufficient low water pressure conditions, in case the water pump gland wearing and tearing, low-pressure water can leak out, the maintenance personal's discovery that can in time be patrolled and examined, and can in time obtain maintenance.The 3rd, air can not infiltrate in the circulatory system, and water pump 92 can be exported the maximum output output that does not have bubble to exist.
When the pump housing of one or several water pump 92 of injection workshop cooling water recirculation system of the present invention or corresponding motor need keep in repair; Only need closing fault water pump 92 pairing water inlet maintenance gate valve 91-1 and backwater maintenance gate valve 94-1; Can carry out maintenance operation then; Can not impact, can not influence the injection moulding of whole workshop yet and produce whole cooling recirculation system.And for only supply-water pump of prior art or with after two to several the supply-water pump parallel connections in injection workshop supply water the simultaneously system of cool cycles of each injection machine; In case when water pump needs repairing, will the production of whole injection workshop be impacted even stop production.
The energy-conservation comparison of injection workshop cooling water recirculation system of the present invention and existing system:
With the happy plastics of Changzhou Wan Jia Co., Ltd 20 (large, medium and small) injection machines of injection workshop is example:
Adopt system of the present invention, for 15 medium and small injection machines, every water pump (15 * 125 watts=1875 watts) that disposes 125 watts; For 5 large size plastic jetting-moulding devices; Two water pumps of every configuration, one 125 watts water pump, (5 * 125 watts=625 watts on one 550 watts water pump; 5 * 550 watts w=2750 watt, amount to 3375 watts); All open general power 5.25kW.
When using the existing system design arrangement, pump power is generally two 7kW water pump parallel connections.It is 14kW (as start one then be 7kW) that 2 7kW water pumps are opened power, in whole year production 300 days:
A 7kW power water pump used annual 300 days in 24 hours: 7kW * 24 * 300=50400kWh/.
Two 7kW power water pump parallel connections are used: 7kW * 2 * 24 * 300=100800kWh/.
Adopt novel water-cooled but circulatory system general power be 5.25kW * 24 * 300=37800kWh/.
Use the annual power consumption of 7kW water pump 50400kWh relatively, adopt after the system of the present invention (50400kWh-37800kWh=12600kWh), can save energy the whole year: 12600kWh.
Use the annual power consumption of two 7kW water pumps 100800kWh relatively, adopt after the system of the present invention (100800kWh-37800kWh=63000kWh), can save energy the whole year: 63000kWh.The said kWh of energy unit is kilowatt-hour, is called for short kilowatt hour, also is the number of degrees that are commonly called as electricity consumption.
Therefore cooling water recirculation system of the present invention can reduce the mass energy waste, meets the overall regulation and control policy of national energy-saving and emission-reduction.
