Abstract
The utility model discloses a kind of miniature electric Pallet truck power unit, comprise the fuel tank and motor that are fixed on centre valve block two ends, in fuel tank centre valve block end face on be provided with the gear pump and return tube that are connected with fuel sucking pipe, described centre valve block is of a size of 80mm × 81mm × 35mm, its adjacent two side offers A hydraulic fluid port and B hydraulic fluid port respectively, B hydraulic fluid port place sidewall is provided with electromagnetism valve opening, opposing side sidewall offers pressure and mend valve opening and overflow valve opening, electromagnetism valve opening and pressure mend that valve opening is relative to be communicated with, be communicated with back oil road in valve body, overflow valve opening is relative with B hydraulic fluid port to be communicated with, be communicated with oil road in valve body.The utility model centre valve block size reduces, and an oil outlet is respectively established in adjacent two side, and pressure is mended valve and is retrofitted in side, and integral structure layout is compacter, and accessory size, weight reduce, and meet miniature electric Pallet truck installation requirement.
Description
Technical field
the utility model relates to hydraulic system power unit field, is specifically related to a kind of miniature electric Pallet truck power unit.
Background technique
Electric pallet truck is widely used in logistics, warehouse, factory, hospital, school, market, airport, stadiums, airport, station etc. place, instead of the heavy physical labor of a dead lift article, but some small space needs a kind of miniature electric Pallet truck to operate.Namely the market demand is the power of new product development, and the automobile-used power unit of electric pallet originally, because of accessory size, structure problem, cannot meet installation requirement.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of miniature electric Pallet truck power unit, and centre valve block size reduces, and an oil outlet is respectively established in adjacent two side, pressure is mended valve and is retrofitted in side, integral structure layout is compacter, and accessory size, weight reduce, and meet installation requirement.
The utility model is achieved through the following technical solutions:
A kind of miniature electric Pallet truck power unit, comprise the fuel tank and motor that are fixed on centre valve block two ends, in fuel tank centre valve block end face on be provided with the gear pump and return tube that are connected with fuel sucking pipe, described centre valve block is of a size of 80mm × 81mm × 35mm, its adjacent two side offers A hydraulic fluid port and B hydraulic fluid port respectively, B hydraulic fluid port place sidewall is provided with electromagnetism valve opening, opposing side sidewall offers pressure and mend valve opening and overflow valve opening, electromagnetism valve opening and pressure mend that valve opening is relative to be communicated with, be communicated with back oil road in valve body, overflow valve opening is relative with B hydraulic fluid port to be communicated with, be communicated with oil road in valve body.
The further improvement project of the utility model is, the solenoid valve installed in described electromagnetism valve opening is screw thread inserting type normally closed solenoid valve.
The utility model further improvement project is, described fuel tank is 1L fuel tank.
The utility model compared with prior art, has following obvious advantage:
The utility model centre valve block is by the size of original 105mm × 105mm × 53mm, change 80mm × 81mm × 35mm into, and change two adjacent surface oil outlets into by an oil outlet, the client that leaves matches installation according to the actual requirements, pressure is mended valve simultaneously and be retrofitted to side, be convenient to dismounting, integral layout is compacter, design of part size reduces, weight saving, meets miniature electric Pallet truck installation requirement.
