Description
Technical field
The present invention relates to technical field of conveying machinery, more particularly, to a kind of durable single-stage non-leakage syrup pump.
Background technology
In the making course of conveying of syrup, after solid sugar material first being melted into syrup, it is delivered to by molasses pump to be added
Work area domain.Because syrup concentration is higher than water, transporting resistance is big, when holding conveying using existing molasses pump, syrup generally be present
Pump weak heat-dissipating, high temperature is easily caused to cause molasses pump service life reduction.The suction eye sealing of existing molasses pump all uses metal
Seal ring seal, easily there is impeller and damaged with sealing ring friction, influence pump performance, cause impeller stuck with sealing ring when serious
（Locking）.At the same time, containment member is easily because of hypertonia in high temperature, pump and frictional resistance is excessive produces aging or damage, and
Trigger leakage, maintenance cost remains high.
The content of the invention
The purpose of the present invention is intended to overcome the shortcomings of the prior art, there is provided and a kind of simple in construction, heat-sinking capability is strong,
The single-stage non-leakage syrup pump of sealed reliable and service life length.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of durable single-stage non-leakage syrup pump, including the pump housing, one end are provided with the pump shaft of impeller, the pump in canned pump body end portion
Lid, the bearing sleeve for being connected on the pump housing by branch sleeve and being connected by bearing with pump shaft, is installed on bearing sleeve end
Bearing gland, be arranged at pump cover and be set in the sealing device on pump shaft, and be arranged at suction eye and pump
Internal wall sealing ring in sealing contact；The bearing sleeve uses double layer hollow structure, and its hollow structure forms cooling water cavity；Institute
State the cooling water inlet that setting connects with cooling water cavity on the outer wall at bearing sleeve adjacent one end, the outer wall of other end vicinity
It is upper that the coolant outlet connected with cooling water cavity is set；The sealing device uses integrated mechanical sealing.
Preferably, the sealing ring is made of polytetrafluoroethylene (PTFE).
Preferably, on the pump shaft, one end of relative impeller is provided with shaft coupling.
Preferably, support has been bolted it on the bearing sleeve.
Preferably, the bearing sleeve is connected by bolt with branch sleeve.
Preferably, the branch sleeve is connected by bolt with the pump housing.
Compared with prior art, the invention has the advantages that：
1st, the pump belongs to cold making pump, and making is simple in construction, complete machine spare and accessory parts are less, can substantially reduce product inventory and be produced into
This, maintenance is convenient.
2nd, flow deflector is rationally disposed in pump housing runner, effectively reduces pump cavitation, strengthens pump body structure intensity, extends water pump
Service life.
3rd, larger cooling water chamber is provided with bearing body, effectively reduce bearing temperature,
4th, by using integrated mechanical sealing, because spring does not contact with medium, effectively extend mechanical seal uses the longevity
Life.
5th, the pump is sealed using food-grade soft PTFE inserts, and lubricity is preferable, super-high wear-resistant, high temperature resistant（200
℃~250℃）, can significantly extend the service life of water pump, it is ensured that pump performance, easy to maintenance quick, operating cost is ultralow.
